What is Life?

WHAT IS LIFE? ERWIN SCHRODINGER

First published 1944 What is life? 

The Physical Aspect of the Living Cell. Based on lectures delivered under the auspices of the Dublin Institute for Advanced Studies at Trinity College, Dublin, in February 1943.



What Is Life? is a 1944 non-fiction science book written for the lay reader by physicist Erwin Schrödinger. The book was based on a course of public lectures delivered by Schrödinger in February 1943, under the auspices of the Dublin Institute for Advanced Studies at Trinity College, Dublin. The lectures attracted an audience of about 400, who were warned "that the subject-matter was a difficult one and that the lectures could not be termed popular, even though the physicist’s most dreaded weapon, mathematical deduction, would hardly be utilized."[1] Schrödinger's lecture focused on one important question: "how can the events in space and time which take place within the spatial boundary of a living organism be accounted for by physics and chemistry?"[1]

In the book, Schrödinger introduced the idea of an "aperiodic crystal" that contained genetic information in its configuration of covalent chemical bonds. In the 1950s, this idea stimulated enthusiasm for discovering the genetic molecule. Although the existence of DNA had been known since 1869, its role in reproduction and its helical shape were still unknown at the time of Schrödinger's lecture. In retrospect, Schrödinger's aperiodic crystal can be viewed as a well-reasoned theoretical prediction of what biologists should have been looking for during their search for genetic material. Both James D. Watson,[2] and independently, Francis Crick, co-discoverers of the structure of DNA, credited Schrödinger's book with presenting an early theoretical description of how the storage of genetic information would work, and each respectively acknowledged the book as a source of inspiration for their initial researches.[3]

Background


The book is based on lectures delivered under the auspices of the Institute at Trinity College, Dublin, in February 1943 and published in 1944. At that time DNA was not yet accepted as the carrier of hereditary information, which only was the case after the Hershey–Chase experiment of 1952. One of the most successful branches of physics at this time was statistical physics, and quantum mechanics, a theory which is also very statistical in its nature. Schrödinger himself is one of the founding fathers of quantum mechanics.
Max Delbrück's thinking about the physical basis of life was an important influence on Schrödinger.[4] Geneticist and 1946 Nobel-prize winner H.J. Muller had in his 1922 article "Variation due to Change in the Individual Gene"[5] already laid out all the basic properties of the heredity molecule that Schrödinger derives from first principles in What is Life?, properties which Muller refined in his 1929 article "The Gene As The Basis of Life"[6] and further clarified during the 1930s, long before the publication of What is Life?[7] [verification needed] But the role of the macromolecule DNA as the genetic material was not yet suspected in 1929, rather, some form of protein was expected to be the genetic material at that time.

Content


In chapter I, Schrödinger explains that most physical laws on a large scale are due to chaos on a small scale. He calls this principle "order-from-disorder." As an example he mentions diffusion, which can be modeled as a highly ordered process, but which is caused by random movement of atoms or molecules. If the number of atoms is reduced, the behaviour of a system becomes more and more random. He states that life greatly depends on order and that a naive physicist may assume that the master code of a living organism has to consist of a large number of atoms.

In chapter II and III, he summarizes what was known at this time about the hereditary mechanism. Most importantly, he elaborates the important role mutations play in evolution. He concludes that the carrier of hereditary information has to be both small in size and permanent in time, contradicting the naive physicist's expectation. This contradiction cannot be resolved by classical physics.

In chapter IV, Schrödinger presents molecules, which are indeed stable even if they consist of only a few atoms, as the solution. Even though molecules were known before, their stability could not be explained by classical physics, but is due to the discrete nature of quantum mechanics. Furthermore mutations are directly linked to quantum leaps.
He continues to explain, in chapter V, that true solids, which are also permanent, are crystals. The stability of molecules and crystals is due to the same principles and a molecule might be called "the germ of a solid." On the other hand an amorphous solid, without crystalline structure, should be regarded as a liquid with a very high viscosity. Schrödinger believes the heredity material to be a molecule, which unlike a crystal does not repeat itself. He calls this an aperiodic crystal. The aperiodic nature allows to encode an almost infinite number of possibilities with a small number of atoms. He finally compares this picture with the known facts and finds it in accordance with them.
In chapter VI Schrödinger states:

...living matter, while not eluding the "laws of physics" as established up to date, is likely to involve "other laws of physics" hitherto unknown, which however, once they have been revealed, will form just as integral a part of science as the former.
He knows that this statement is open to misconception and tries to clarify it. The main principle involved with "order-from-disorder" is the second law of thermodynamics, according to which entropy only increases in a closed system (such as the universe). Schrödinger explains that living matter evades the decay to thermodynamical equilibrium by homeostatically maintaining negative entropy (today this quantity is called information[8]) in an open system.

In chapter VII, he maintains that "order-from-order" is not absolutely new to physics; in fact, it is even simpler and more plausible. But nature follows "order-from-disorder", with some exceptions as the movement of the celestial bodies and the behaviour of mechanical devices such as clocks. But even those are influenced by thermal and frictional forces. The degree to which a system functions mechanically or statistically depends on the temperature. If heated, a clock ceases to function, because it melts. Conversely, if the temperature approaches absolute zero, any system behaves more and more mechanically. Some systems approach this mechanical behaviour rather fast with room temperature already being practically equivalent to absolute zero.

Schrödinger concludes this chapter and the book with philosophical speculations on determinism, free will, and the mystery of human consciousness. He believes he must reconcile two premises: (1) the body fully obeys the laws of quantum mechanics, where quantum indeterminacy plays no important role except to increase randomness at the quantum scale; and (2) there is "incontrovertible direct experience" that we freely direct our bodies, can predict outcomes, and take responsibility for our choice of action. Schrödinger rejects the idea that the source of consciousness should perish with the body because he finds the idea "distasteful". He also rejects the idea that there are multiple immortal souls that can exist without the body because he believes that consciousness is nevertheless highly dependent on the body. Schrödinger writes that, to reconcile the two premises,
The only possible alternative is simply to keep to the immediate experience that consciousness is a singular of which the plural is unknown; that there is only one thing and that what seems to be a plurality is merely a series of different aspects of this one thing...
Any intuitions that consciousness is plural, he says, are illusions. Schrödinger is sympathetic to the Hindu concept of Brahman, by which each individual's consciousness is only a manifestation of a unitary consciousness pervading the universe - which corresponds to the Hindu concept of God. Schrödinger concludes that "...'I' -am the person, if any, who controls the 'motion of the atoms' according to the Laws of Nature. However, he also qualifies the conclusion as "necessarily subjective" in its "philosophical implications." In the final paragraph, he points out that what is meant by "I" is not the collection of experienced events but "namely the canvas upon which they are collected." If a hypnotist succeeds in blotting out all earlier reminiscences, he writes, there would be no loss of personal existence - "Nor will there ever be."[9]

Schrödinger's "paradox"


In a world governed by the second law of thermodynamics, all isolated systems are expected to approach a state of maximum disorder. Since life approaches and maintains a highly ordered state - some argue that this seems to violate the aforementioned Second Law implicating a paradox. However, since life is not an isolated system, there is no paradox. The increase of order inside an organism is more than paid for by an increase in disorder outside this organism. By this mechanism, the Second Law is obeyed, and life maintains a highly ordered state, which it sustains by causing a net increase in disorder in the Universe. In order to increase the complexity on Earth - as life does - you need energy. Most of the energy for life here on Earth is provided by the Sun.

Fractals and Antennas and The Economy




 The intuitive framework has to recognize that you have already worked the angles and that such intuition is gathered from all that has been worked. This contradicts what you are saying. I am not saying it is right just that I have seen this perspective in development with regard to scientists as they push through the wall that has separated them from moving on. This then details a whole set of new parameters in which the thinking mind can move forward with proposals.


 
 I never quite could get the economy either, until I understood the idea of Fractals as a gesture of the underlying pattern of all of the economy in expression. Of course that is my point of view.  I might of called it the algorithm before.

 The idea here is that all thing are expression of the underlying pattern and you might call the end result psychology or sociology of thinking and life as a result.

 It seems that the accumulated reference of mind as a place in it's evolution is to see that all the statistical information is already parametrized by the judgements in which you give them personally?

 Ultimately this is the setting for which your conclusions guide your perspective, yet, it is when we look back, one can choose too, "guide their brain?"



If you did not pick it up, Benoit was able to reduce the economy too, and used an inductive deductive facility in regard to what is self evident. But I would point out what you might have interpreted as illusory in terms of the graph he sees on the board was instrumental to his penetrating the pattern in the economy.

Just raising the name of Nassim Nicholas Taleb and the idea of the Black Swan in relation to the basis of the economy Benoit raises deeper questions and does garner a look for me. I don't know what to expects is opening up the door to understanding more about such erudition's but they are with regard to the economy.




 Taleb was collaborating with Benoit Mandelbrot on a general theory of risk management Collaborations

A simple assumption about heads and tails, leads to bell curves and such?

Taleb, N. N. (2008) Edge article: Real Life is Not a Casino

So you are looking at both sides of the coin.

More on the Black Swan here.



 While these writings are disparate pieces, do they indeed come together under this post book review?? As a scientist and mathematics person are you not intrigued about "the pattern?" I was shocked.....yet is made sense.

Now Nassim adds dimension to the subject. "He calls for cancellation of the Nobel Memorial Prize in Economics, saying that the damage from economic theories can be devastating".

Game theory if you know how it works it is used in all types of negotiation.

John Maynard Smith,[1] F.R.S. (6 January 1920 – 19 April 2004) was a British theoretical evolutionary biologist and geneticist. Originally an aeronautical engineer during the Second World War, he then took a second degree in genetics under the well-known biologist J.B.S. Haldane. Maynard Smith was instrumental in the application of game theory to evolution and theorized on other problems such as the evolution of sex and signalling theory.

Biography

Early years

John Maynard Smith was born in London, the son of a surgeon, but following his father's death in 1928 the family moved to Exmoor, where he became interested in natural history. Quite unhappy with the lack of formal science education at Eton College, Maynard Smith took it upon himself to develop an interest in Darwinian evolutionary theory and mathematics, after having read the work of old Etonian J.B.S. Haldane, whose books were in the school's library despite the bad reputation Haldane had at Eton for his communism.
On leaving school, Maynard Smith joined the Communist Party of Great Britain and started studying engineering at Trinity College Cambridge. When the Second World War broke out in 1939, he defied his party's line and volunteered for service. He was rejected, however, because of poor eyesight and was told to finish his engineering degree, which he did in 1941. He later quipped that "under the circumstances, my poor eyesight was a selective advantage—it stopped me getting shot". The year of his graduation, he married Sheila Matthew, and they later had two sons and one daughter (Tony, Carol, and Julian). Between 1942 and 1947 he applied his degree to military aircraft design.

Second degree

Maynard Smith then took a change of career, entering University College London (UCL) to study fruit fly genetics under Haldane. After graduating he became a lecturer in Zoology at UCL between 1952 and 1965, where he directed the Drosophila lab and conducted research on population genetics. He published a popular Penguin book, The Theory of Evolution, in 1958 (with subsequent editions in 1966, 1975, 1993).
He became gradually less attracted to communism and became a less active member, finally leaving the Party in 1956 like many other intellectuals, after the Soviet Union brutally suppressed the Hungarian Revolution (Haldane had left the party in 1950 after becoming similarly disillusioned).

University of Sussex

In 1962 he was one of the founding members of the University of Sussex and was a Dean between 1965-85. He subsequently became a professor emeritus. Prior to his death the building housing much of Life Sciences at Sussex was renamed the John Maynard Smith Building, in his honour.

Evolution and the Theory of Games

In 1973 Maynard Smith formalised a central concept in game theory called the evolutionarily stable strategy (ESS), based on a verbal argument by George R. Price. This area of research culminated in his 1982 book Evolution and the Theory of Games. The Hawk-Dove game is arguably his single most influential game theoretical model.
He was elected a Fellow of the Royal Society in 1977. In 1986 he was awarded the Darwin Medal. He also developed and recovered from colon cancer.

Evolution of sex and other major transitions in evolution

Maynard Smith published a book entitled The Evolution of Sex which explored in mathematical terms, the notion of the "two-fold cost of sex". During the late 1980s he also became interested in the other major evolutionary transitions with the biochemist Eörs Szathmáry. Together they wrote an influential 1995 book The Major Transitions in Evolution, a seminal work which continues to contribute to ongoing issues in evolutionary biology.[2][3] . A popular science version of the book, entitled The Origins of Life: From the birth of life to the origin of language was published in 1999.
In 1991 he was awarded the Balzan Prize for Genetics and Evolution "For his powerful analysis of evolutionary theory and of the role of sexual reproduction as a critical factor in evolution and in the survival of species; for his mathematical models applying the theory of games to evolutionary problems" (motivation of the Balzan General Prize Committee). In 1995 he was awarded the Linnean Medal by The Linnean Society and in 1999 he was awarded the Crafoord Prize jointly with Ernst Mayr and George C. Williams. In 2001 he was awarded the Kyoto Prize.
In his honour, the European Society for Evolutionary Biology has an award for extraordinary young evolutionary biology researchers named The John Maynard Smith Prize.

Animal Signals

His final book, Animal Signals, co-authored with David Harper was published in 2003 on signalling theory.

Death

He died of lung cancer[4]—sitting in a high-backed chair, surrounded by books—at his home in Lewes, East Sussex on April 19, 2004, 122 years to the day after the death of Darwin. At his funeral, one of his grandchildren said, "he was very smart... and a jolly nice person". He was survived by his wife Sheila and their children.

Psychohistory

Hari Seldon, a fictional character, is the intellectual hero of Isaac Asimov's Foundation Series. In his capacity as mathematics professor at Streeling University on Trantor, he developed psychohistory, allowing him to predict the future in probabilistic terms. His prediction of the eventual fall of the Galactic Empire is the reason behind his nickname "The Raven" Seldon.
Psychohistory is a fictional science in Isaac Asimov's Foundation universe which combines history, sociology, and mathematical statistics to make (nearly) exact predictions of the collective actions of very large groups of people, such as the Galactic Empire. It was first introduced in the five short stories (1942–1944) which would later be collected as the 1951 novel Foundation.

The Theory of Moral Sentiments

Author Adam Smith
Publication date 1759
The Theory of Moral Sentiments was written by Adam Smith in 1759. It provided the ethical, philosophical, psychological, and methodological underpinnings to Smith's later works, including The Wealth of Nations (1776), A Treatise on Public Opulence (1764) (first published in 1937), Essays on Philosophical Subjects (1795), and Lectures on Justice, Police, Revenue, and Arms (1763) (first published in 1896).

Contents

Overview

Broadly speaking, Smith followed the views of his mentor, Francis Hutcheson of the University of Glasgow, who divided moral philosophy into four parts: Ethics and Virtue; Private rights and Natural liberty; Familial rights (called Economics); and State and Individual rights (called Politics).
More specifically, Smith divided moral systems into:
  • Categories of the nature of morality. These included Propriety, Prudence, and Benevolence.
  • Categories of the motive of morality. These included Self-love, Reason, and Sentiment.
Hutcheson had abandoned the psychological view of moral philosophy, claiming that motives were too fickle to be used as a basis for a philosophical system. Instead, he hypothesised a dedicated "sixth sense" to explain morality. This idea, to be taken up by David Hume (see Hume's A Treatise of Human Nature), claimed that man is pleased by utility.
Smith rejected his teacher's reliance on this special sense. Starting in about 1741, Smith set on the task of using Hume's experimental method (appealing to human experience) to replace the specific moral sense with a pluralistic approach to morality based on a multitude of psychological motives. The Theory of Moral Sentiments begins with the following assertion:
How selfish soever man may be supposed, there are evidently some principles in his nature, which interest him in the fortunes of others, and render their happiness necessary to him, though he derives nothing from it, except the pleasure of seeing it. Of this kind is pity or compassion, the emotion we feel for the misery of others, when we either see it, or are made to conceive it in a very lively manner. That we often derive sorrow from the sorrows of others, is a matter of fact too obvious to require any instances to prove it; for this sentiment, like all the other original passions of human nature, is by no means confined to the virtuous or the humane, though they perhaps may feel it with the most exquisite sensibility. The greatest ruffian, the most hardened violator of the laws of society, is not altogether without it.
Smith departed from the "moral sense" tradition of Shaftesbury, Hutcheson, and Hume, as the principle of sympathy takes the place of that organ. "Sympathy" was the term Smith used for the feeling of these moral sentiments. It was the feeling with the passions of others. It operated through a logic of mirroring, in which a spectator imaginatively reconstructed the experience of the person he watches:
As we have no immediate experience of what other men feel, we can form no idea of the manner in which they are affected, but by conceiving what we ourselves should feel in the like situation. Though our brother is on the rack, as long as we ourselves are at our ease, our senses will never inform us of what he suffers. They never did, and never can, carry us beyond our own person, and it is by the imagination only that we can form any conception of what are his sensations. Neither can that faculty help us to this any other way, than by representing to us what would be our own, if we were in his case. It is the impressions of our own senses only, not those of his, which our imaginations copy. By the imagination, we place ourselves in his situation.
Sympathy arose from an innate desire to identify with the emotions of others. It could lead people to strive to maintain good relations with their fellow human beings and provide the basis both for specific benevolent acts and for the general social order. Thus was formed within the beast the psychological basis for the desire to obey natural laws. The Theory of Moral Sentiments culminated in man as self-interested and self-commanded. Individual freedom, according to Smith, was rooted in self-reliance, the ability of an individual to pursue his self-interest while commanding himself based on the principles of natural law.
However, Smith rejected the idea that Man was capable of forming moral judgements beyond a limited sphere of activity, again centered around his own self-interest:
The administration of the great system of the universe ... the care of the universal happiness of all rational and sensible beings, is the business of God and not of man. To man is allotted a much humbler department, but one much more suitable to the weakness of his powers, and to the narrowness of his comprehension: the care of his own happiness, of that of his family, his friends, his country.... But though we are ... endowed with a very strong desire of those ends, it has been entrusted to the slow and uncertain determinations of our reason to find out the proper means of bringing them about. Nature has directed us to the greater part of these by original and immediate instincts. Hunger, thirst, the passion which unites the two sexes, and the dread of pain, prompt us to apply those means for their own sakes, and without any consideration of their tendency to those beneficent ends which the great Director of nature intended to produce by them.
It was in the TMS that Smith first referred to the "invisible hand" to describe the apparent benefits to society of people behaving in their own interests. Smith writes (6th ed. p. 350):
... In spite of their natural selfishness and rapacity, though they mean only their own conveniency, though the sole end which they propose ... be the gratification of their own vain and insatiable desires, they divide with the poor the produce of all their improvements. They are led by an invisible hand to make nearly the same distribution of the necessaries of life, which would have been made, had the earth been divided into equal portions among all its inhabitants, and thus without intending it, without knowing it, advance the interest of the society.
In a published lecture, Vernon L. Smith further argued that Theory of Moral Sentiments and Wealth of Nations together encompassed:
"one behavioral axiom, 'the propensity to truck, barter, and exchange one thing for another,' where the objects of trade I will interpret to include not only goods, but also gifts, assistance, and favors out of sympathy ... whether it is goods or favors that are exchanged, they bestow gains from trade that humans seek relentlessly in all social transactions. Thus, Adam Smith's single axiom, broadly interpreted ... is sufficient to characterize a major portion of the human social and cultural enterprise. It explains why human nature appears to be simultaneously self-regarding and other-regarding."[1]

The Theory of Moral Sentiments: The Fourth Edition

Consists of 6 parts:
  • Part I: Of the propriety of action
  • Part II: Of merit and demerit; or of the objects of reward and punishment
  • Part III: Of the foundations of our judgments concerning our own sentiments and conduct, and of the sense of duty.
  • Part IV: Of the effect of utility upon the sentiments of approbation.
  • Part V: Of the influence of custom and fashion upon the sentiments of moral approbation and disapprobation.
  • Part VI: Of systems of moral philosophy

Part I: Of the propriety of action

Part one of the Theory of Moral Sentiments consists of three sections:
  • Section 1: Of the sense of propriety
  • Section 2: Of the degrees of which different passions are consistent with propriety
  • Section 3: Of the effects of propriety and adversity upon the judgment of mankind with regard to the propriety of action; and why it is more easy to obtain their approbation in the one state than the other

 Part I, Section I: Of the Sense of Propriety

Section 1 consists of 5 chapters:
  • Chapter 1: Of sympathy
  • Chapter 2: Of the pleasure of mutual sympathy
  • Chapter 3: Of the manner in which we judge of the propriety or impropriety of the affections of other men by their concord or dissonance with our own
  • Chapter 4: The same subject continued
  • Chapter 5: Of the amiable and respectable virtues
Part I, Section I, Chapter I: Of Sympathy
According to Smith humans have a natural tendency to care about the well-being of others for no other reason than the pleasure one gets from seeing them happy. He calls this sympathy, defining it "our fellow-feeling with any passion whatsoever" (p. 5). He argues that this occurs under either of two conditions:
  • We see firsthand the fortune or misfortune of another person
  • The fortune or misfortune is vividly depicted to us
Although this is apparently true, he follows to argue that this tendency lies even in "the greatest ruffian, the most hardened violator of the laws of society" (p.2).
Smith also proposes several variables that can moderate the extent of sympathy, noting that the situation that is the cause of the passion is the large determinant of our response:
  • The vividness of the account of the condition of another person
An important point put forth by Smith is that the degree to which we sympathize, or "tremble and shudder at the thought of what he feels", is proportional to the degree of vividness in our observation or the description of the event.
  • Knowledge of the causes of the emotions
When observing the anger of another person, for example, we are unlikely to sympathize with this person because we "are unacquainted with his provocation" and as a result cannot imagine what it is like to feel what he feels. Further, since we can see the "fear and resentment" of those who are the targets of the person's anger we are likely to sympathize and take side with them. Thus, sympathetic responses are often conditional on or their magnitude is determined by the causes of the emotion in the person being sympathized with.
  • Whether other people are involved in the emotion
Specifically, emotions such as joy and grief tell us about the "good or bad fortune" of the person we are observing them in, whereas anger tells us about the bad fortune with respect to another person. It is the difference between intrapersonal emotions, such as joy and grief, and interpersonal emotions, such as anger, that causes the difference in sympathy, according to Smith. That is, intrapersonal emotions trigger at least some sympathy without the need for context whereas interpersonal emotions are dependent on context.

He also proposes a natural 'motor' response to seeing the actions of others: If we see a knife hacking off a person's leg we wince away, if we see someone dance we move in the same ways, we feel the injuries of others as if we had them ourselves.

Smith makes clear that we sympathize not only with the misery of others but also the joy; he states that observing an emotional state through the "looks and gestures" in another person is enough to initiate that emotional state in ourselves. Furthermore, we are generally insensitive to the real situation of the other person; we are instead sensitive to how we would feel ourselves if we were in the situation of the other person. For example, a mother with a suffering baby feels "the most complete image of misery and distress" while the child merely feels "the uneasiness of the present instant" (p. 8).
Part I, Section I, Chapter II: Of Pleasure and mutual sympathy
Smith continues by arguing that people feel pleasure from the presence of others with the same emotions as one's self, and displeasure in the presence of those with "contrary" emotions. Smith argues that this pleasure is not the result of self-interest: that others are more likely to assist oneself if they are in a similar emotional state. Smith also makes the case that pleasure from mutual sympathy is not derived merely from a heightening of the original felt emotion amplified by the other person. Smith further notes that people get more pleasure from the mutual sympathy of negative emotions than positive emotions, but we feel "more anxious to communicate to our friends" (p. 13) our negative emotions.

Smith proposes that mutual sympathy heightens the original emotion and "disburdens" the person of sorrow. This is a 'relief' model of mutual sympathy, where mutual sympathy heightens the sorrow but also produces pleasure from relief "because the sweetness of his sympathy more than compensates the bitterness of that sorrow" (p. 14). In contrast, mocking or joking about their sorrow is the "cruelest insult" one can inflict on another person:
To seem to not be affected by the joy of our companions is but want of politeness; but to not wear a serious countentance when they tell us their afflictions, is real and gross inhumanity (p. 14).
He makes clear that mutual sympathy of negative emotions is a necessary condition for friendship, whereas mutual sympathy of positive emotions is desirable but not required. This is due to the "healing consolation of mutual sympathy" that a friend is 'required' to provide in response to "grief and resentment", as if not doing so would be akin to a failure to help the physically wounded.

Not only do we get pleasure from the sympathy of others, but we also obtain pleasure from being able to successfully sympathize with others, and discomfort from failing to do so. Sympathizing is pleasurable, failing to sympathize is aversive. Smith also makes the case that failing to sympathize with another person may not be aversive to ourselves but we may find the emotion of the other person unfounded and blame them, as when another person experiences great happiness or sadness in response to an event that we think should not warrant such a response.
Part I, Section I, Chapter III: Of the manner in which we judge of the propriety or impropriety of the affections of other men by their concord or dissonance with our own
Smith presents the argument that approval or disapproval of the feelings of others is completely determined by whether we sympathize or fail to sympathize with their emotions. Specifically, if we sympathize with the feelings of another we judge that their feelings are just, and if we do not sympathize we judge that their feelings are unjust.
This holds in matters of opinion also, as Smith flatly states that we judge the opinions of others as correct or incorrect merely by determining whether they agree with our own opinions. Smith also cites a few examples where our judgment is not in line with our emotions and sympathy, as when we judge the sorrow of a stranger who has lost her mother as being justified even though we know nothing about the stranger and do not sympathize ourselves. However, according to Smith these non-emotional judgments are not independent from sympathy in that although we do not feel sympathy we do recognize that sympathy would be appropriate and lead us to this judgment and thus deem the judgment as correct.

Next, Smith puts forth that not only are the consequences of one's actions judged and used to determine whether one is just or unjust in committing them, but also whether one's sentiments justified the action that brought about the consequences. Thus, sympathy plays a role in determining judgments of the actions of others in that if we sympathize with the affections that brought about the action we are more likely to judge the action as just, and vice versa:
If upon bringing the case home to our own breast we find that the sentiments which it gives occasion to, coincide and tally with our own, we necessarily approve of them as proportioned and suitable to their objects; if otherwise, we necessarily disapprove of them, as extravagant and out of proportion (p. 20).
Part I, Section I, Chapter IV: The same subject continued
Smith delineates two conditions under which we judge the "propriety or impropriety of the sentiments of another person":
  • 1 When the objects of the sentiments are considered alone
  • 2 When the objects of the sentiments are considered in relation to the person or other persons
When one's sentiments coincide with another person's when the object is considered alone, then we judge that their sentiment is justified. Smith lists objects that are in one of two domains: science and taste. Smith argues that sympathy does not play a role in judgments of these objects; differences in judgment arise only due to difference in attention or mental acuity between people. When the judgment of another person agrees with us on these types of objects it is not notable; however, when another person's judgment differs from us, we assume that they have some special ability to discern characteristics of the object we have not already noticed, and thus view their judgment with special approbation called admiration.

Smith continues by noting that we assign value to judgments not based on usefulness (utility) but on similarity to our own judgment, and we attribute to those judgments which are in line with our own the qualities of correctness or truth in science, and justness or delicateness in taste. Thus, the utility of a judgment is "plainly an afterthought" and "not what first recommends them to our approbation" (p. 24).

Of objects that fall into the second category, such as the misfortune of oneself or another person, Smith argues that there is no common starting point for judgment but are vastly more important in maintaining social relations. Judgments of the first kind are irrelevant as long as one is able to share a sympathetic sentiment with another person; people may converse in total disagreement about objects of the first kind as long as each person appreciates the sentiments of the other to a reasonable degree. However, people become intolerable to each other when they have no or sympathy for the misfortunes or resentment of each other: "You are confounded at my violence and passion, and I am enraged at your cold insensibility and want of feelings" (p. 26).

Another important point Smith makes is that our sympathy will never reach the degree or "violence" of the person who experiences it, as our own "safety" and comfort as well as separation from the offending object constantly "intrude" on our efforts to induce a sympathetic state in ourselves. Thus, sympathy is never enough, as the "sole consolation" for the sufferer is " to see the emotions of their hearts, in every respect, beat time to his own, in the violent and disagreeable passions" (p. 28). Therefore, the original sufferer is likely to dampen her feelings to be in "concord" with the degree of sentiment expressible by the other person, who feels only due to the ability of one's imagination. It is this which is "sufficient for the harmony of society" (p. 28). Not only does the person dampen her expression of suffering for the purpose of sympathizing, but she also takes the perspective of the other person who is not suffering, thus slowly changing her perspective and allowing the calmness of the other person and reduction of violence of the sentiment to improve her spirits.

As a friend is likely to engage in more sympathy than a stranger, a friend actually slows the reduction in our sorrows because we do not temper our feelings out of sympathizing with the perspective of the friend to the degree that we reduce our sentiments in the presence of acquaintances or a group of acquaintances. This gradual tempering of our sorrows from repeated perspective taking of someone in a more calm state make "society and conversation...the most powerful remedies for restoring the mind to its tranquility" (p. 29).
Part I, Section I, Chapter V: Of the amiable and respectable virtues
Smith starts to use an important new distinction in this section and late in the previous section:
  • The "person principally concerned": The person who has had emotions aroused by an object
  • The spectator: The person observing and sympathizing with the emotionally aroused "person principally concerned"
These two people have two different sets of virtues. The person principally concerned, in "bring[ing] down emotions to what the spectator can go along with" (p. 30), demonstrates "self-denial" and "self-government" whereas the spectator displays "the candid condescension and indulgent humanity" of "enter[ing]into the sentiments of the person principally concerned."

Smith returns to anger and how we find "detestable...the insolence and brutality" of the person principally concerned but "admire...the indignation which they naturally call forth in that of the impartial spectator" (p. 32). Smith concludes that the "perfection" of human nature is this mutual sympathy, or "love our neighbor as we love ourself" by "feeling much for others and little for ourself" and to indulge in "benevolent affections" (p. 32). Smith makes clear that it is this ability to "self-command" our "ungovernable passions" through sympathizing with others that is virtuous.

Smith further distinguishes between virtue and propriety:

Part I, Section II: Of the degrees of which different passions are consistent with propriety

  • Chapter 1: Of the passions which take their origins from the body
  • Chapter 2: Of the passions which take their origins from a particular turn or habit of the imagination
  • Chapter 3: Of the unsocial passions
  • Chapter 4: Of the social passions
  • Chapter 5: Of the selfish passions
Smith starts off by noting that the spectator can sympathize only with passions of medium "pitch". However, this medium level at which the spectator can sympathize depends on what "passion" or emotion is being expressed; with some emotions even the most justified expression of cannot be tolerated at a high level of fervor, at others sympathy in the spectator is not bounded by magnitude of expression even though the emotion is not as well justified. Again, Smith emphasizes that specific passions will be considered appropriate or inappropriate to varying degrees depending on the degree to which the spectator is able to sympathize, and that it is the purpose of this section to specify which passions evoke sympathy and which do not and therefore which are deemed appropriate and not appropriate.
Part I, Section II, Chapter I: Of the passions which take their origins from the body
Since it is not possible to sympathize with bodily states or "appetites which take their origin in the body" it is improper to display them to others, according to Smith. One example is "eating voraciously" when hungry, as the impartial spectator can sympathize a little bit if there is a vivid description and good cause for this hunger, but not to a great extent as hunger itself cannot be induced from mere description. Smith also includes sex as a passion of the body that is considered indecent in the expression of others, although he does make note that to fail to treat a woman with more "gaiety, pleasantry, and attention" would also be improper of a man (p. 39). To express pain is also considered unbecoming.

Smith believes the cause of lack of sympathy for these bodily passions is that "we cannot enter into them" ourselves (p. 40). Temperance, by Smith's account, is to have control over bodily passions.

On the contrary, passions of the imagination, such as loss of love or ambition, are easy to sympathize with because our imagination can conform to the shape of the sufferer, whereas our body cannot do such a thing to the body of the sufferer. Pain is fleeting and the harm only lasts as long as the violence is inflicted, whereas an insult lasts to harm for longer duration because our imagination keeps mulling it over. Likewise, bodily pain that induces fear, such as a cut, wound or fracture, evoke sympathy because of the danger that they imply for ourselves; that is, sympathy is activated chiefly through imagining what it would be like for us.
Part I, Section II, Chapter II: Of the passions which take their origins from a particular turn or habit of the imagination
Passions which "take their origins from a particular turn or habit of the imagination" are "little sympathized with". These include love, as we are unlikely to enter into our own feeling of love in response to that of another person and thus unlikely to sympathize. He further states that love is "always laughed at, because we cannot enter into it" ourselves.
Instead of inspiring love in ourselves, and thus sympathy, love makes the impartial spectator sensitive to the situation and emotions that may arise from the gain or loss of love.

Again this is because it is easy to imagine hoping for love or dreading loss of love but not the actual experience of it, and that the "happy passion, upon this account, interests us much less than the fearful and the melancholy" of losing happiness (p. 49). Thus, love inspires sympathy for not for love itself but for the anticipation of emotions from gaining or losing it.
Smith, however, finds love "ridiculous" but "not naturally odious" (p. 50). Thus, we sympathize with the "humaneness, generosity, kindness, friendship, and esteem" (p. 50) of love. However, as these secondary emotions are excessive in love, one should not express them but in moderate tones according to Smith, as:
All these are objects which we cannot expect should interest our companions in the same degree in which they interest us.
Failing to do so makes bad company, and therefore those with specific interests and "love" of hobbies should keep their passions to those with kindred spirits ("A philosopher is company to a philosopher only" (p. 51)) or to themselves.
Part I, Section II, Chapter III: Of the unsocial passions
Smith talks of hatred and resentment next, as "unsocial passions." According to Smith these are passions of imagination, but sympathy is only likely to be evoked in the impartial spectator when they are expressed in moderate tones. Because these passions regard two people, namely the offended (resentful or angry person) and the offender, our sympathies are naturally drawn between these two. Specifically, although we sympathize with the offended person, we fear that the offended person may do harm to the offender, and thus also fear for and sympathize with the danger that faces the offender.

The impartial spectator sympathizes with the offended person in a manner, as emphasized previously, such that the greatest sympathy occurs when the offended person expresses anger or resentment in a temperate manner. Specifically, if the offended person seems just and temperate in coping with the offense, then this magnifies the misdeed done to the offended in the mind of the spectator, increasing sympathy. Although excess anger does not beget sympathy, neither does too little anger, as this may signal fear or uncaring on the part of the offended. This lack of response is just as despicable to the impartial spectator as is the excesses of anger.

However, in general, any expression of anger is improper in the presence of others. This is because the "immediate effects [of anger] are disagreeable" just as the knives of surgery are disagreeable for art, as the immediate effect of surgery is unpleasant even though long-term effect is justified. Likewise, even when anger is justly provoked, it is disagreeable. According to Smith, this explains why we reserve sympathy until we know the cause of the anger or resentment, as if the emotion is not justified by the action of another person, than the immediate disagreeableness and threat to the other person (and by sympathy to ourselves) overwhelm any sympathy that the spectator may have for the offended. In response to expressions of anger, hatred, or resentment, it is likely that the impartial spectator will not feel anger in sympathy with the offended but instead anger toward the offended for expressing such an aversive. Smith believes that there is some form of natural optimality to the aversiveness of these emotions, as it reduces the propagation of ill will among people, and thus increases the probability of functional societies.

Smith also puts forth that anger, hatred, and resentment are disagreeable to the offended mostly because of the idea of being offended rather than the actual offense itself. He remarks that we are likely able to do without what was taken from us, but it is the imagination which angers us at the thought of having something taken. Smith closes this section by remarking that the impartial spectator will not sympathize with us unless we are willing to endure harms, with the goal of maintaining positive social relations and humanity, with equanimity, as long as it does not put us in a situation of being "exposed to perpetual insults" (p. 59). It is only "with reluctance, from necessity, and in consequence of great and repeated provocations" (p. 60) that we should take revenge on others. Smith makes clear that we should take very good care to not act on the passions of anger, hatred, resentment, for purely social reasons, and instead imagine what the impartial spectator would deem appropriate, and base our action solely on a cold calculation.
Part I, Section II, Chapter IV: Of the social passions
The social emotions such as "generosity, humanity, kindness, compassion, mutual friendship and esteem" are considered overwhelmingly with approbation by the impartial spectator. The agreeableness of the "benevolent" sentiments leads to full sympathy on the part of the spectator with both the person concerned and the object of these emotions and are not felt as aversive to the spectator if they are in excess.
Part I, Section II, Chapter V: Of the selfish passions
The final set of passions, or "selfish passions", are grief and joy, which Smith considers to be not so aversive as the unsocial passions of anger and resentment, but not so benevolent as the social passions such as generosity and humanity. Smith makes clear in this passage that the impartial spectator is unsympathetic to the unsocial emotions because they put the offended and the offender in opposition to each other, sympathetic to the social emotions because they join the lover and beloved in unison, and feels somewhere in between with the selfish passions as they are either good or bad for only one person and are not disagreeable but not so magnificent as the social emotions.
Of grief and joy, Smith notes that small joys and great grief are assured to be returned with sympathy from the impartial spectator, but not other degrees of these emotions. Great joy is likely to be met with envy, so modesty is prudent for someone who has come upon great fortune or else suffer the consequences of envy and disapprobation. This is appropriate as the spectator appreciates the lucky individual's "sympathy with our envy and aversion to his happiness" especially because this shows concern for the inability of the spectator to reciprocate the sympathy toward the happiness of the lucky individual. According to Smith, this modesty wears on the sympathy of both the lucky individual and the old friends of the lucky individual and they soon part ways; likewise, the lucky individual may acquire new friends of higher ranks who he must also be modest to, apologizing for the "mortification" of now becoming their equal:
He generally grows weary too soon, and is provoked, by the sullen and suspicious pride of the one, and by the saucy contempt of the other, to treat the first with neglect, and the second with petulance, till at last he grows habitually insolent, and forfeits the esteem of them all...those sudden changes of fortune seldom contribute much to happiness (p. 66).
The solution is to ascend social rank by gradual steps, with the path cleared for one by approbation before one takes the next step, giving people time to adjust, and thus avoiding any "jealousy in those he overtakes, or any envy in those he leaves behind" (p. 66).
Small joys of every day life are met with sympathy and approbation according to Smith. These "frivolous nothings which fill up the void of human life" (p. 67) divert attention and help us forget problems, reconciling us as with a lost friend.
The opposite is true for grief, with small grief triggering no sympathy in the impartial spectator, but large grief with much sympathy. Small griefs are likely, and appropriately, turned into joke and mockery by the sufferer, as the sufferer knows how complaining about small grievances to the impartial spectator will evoke ridicule in the heart of the spectator, and thus the sufferer sympathizes with this, mocking himself to some degree.

Part I, Section III

Of the effects of propriety and adversity upon the judgment of mankind with regard to the propriety of action; and why it is more easy to obtain their approbation in the one state than in the other

Part V, Section V, Chapter I: Of the influence of Custom and Fashion upon the Sentiments of Approbation and Disapprobation

Smith argues that two principles, custom and fashion, pervasively influence judgment. These are based on the modern psychological concept of associativity: Stimuli presented closely in time or space become mentally linked over time and repeated exposure. In Smith's own words:
When two objects have frequently been seen together, the imagination requires a habit of passing easily from one to the other. If the first is to appear, we lay our account that the second is to follow. Of their own accord they put us in mind of one another, and the attention glides easily along them. (p. 1)
Regarding custom, Smith argues that approbation occurs when stimuli are presented according to how one is accustomed to viewing them and disapprobation occurs when they are presented in a way that one is not accustomed to. Thus, Smith argues for social relativity of judgment meaning that beauty and correctness are determined more by what one has previously been exposed to rather than an absolute principle. Although Smith places greater weight on this social determination he does not discount absolute principles completely, instead he argues that that evaluations are rarely inconsistent with custom, therefore giving greater weight to customs than absolutes:
I cannot, however, be induced to believe that our sense of external beauty is founded altogether on custom...But though I cannot admit that custom is the sole principle of beauty, yet I can so far allow the truth of this ingenious system as to grant, that there is scarce any one external form to please, if quite contrary to custom...(p.14-15).
Smith continues by arguing that fashion is a particular "species" of custom. Fashion is specifically the association of stimuli with people of high rank, for example, a certain type of clothes with a notable person such as a king or a renowned artist. This is because the "graceful, easy, and commanding manners of the great" (p.3) person are frequently associated with the other aspects of the person of high rank (e.g., clothes, manners), thus bestowing upon the other aspects the "graceful" quality of the person. In this way objects become fashionable. Smith includes not only clothes and furniture in the sphere of fashion, but also taste, music, poetry, architecture, and physical beauty.
Smith also points out that people should be relatively reluctant to change styles from what they are accustomed to even if a new style is equal to or slightly better than current fashion: "A man would be ridiculous who should appear in public with a suit of clothes quite different from those which are commonly worn, though the new dress be ever so graceful or convenient" (p. 7).
Physical beauty, according to Smith, is also determined by the principle of custom. He argues that each "class" of things has a "peculiar conformation which is approved of" and that the beauty of each member of a class is determined by the extent to which it has the most "usual" manifestation of that "conformation":
Thus, in the human form, the beauty of each feature lies in a certain middle, equally removed from a variety of other forms that are ugly. (p. 10-11).

Part V, Section V, Chapter II: Of the influence of Custom and Fashion upon Moral Sentiments

Smith argues that the influence of custom is reduced in the sphere of moral judgment. Specifically, he argues that there are bad things that no custom can bring approbation to:
But the characters and conduct of a Nero, or a Claudius, are what no custom will ever reconcile us to, what no fashion will ever render agreeable; but the one will always be the object of dread and hatred; the other of scorn and derision. (p. 15-16).
Smith further argues for a "natural" right and wrong, and that custom amplifies the moral sentiments when one's customs are consistent with nature, but dampens moral sentiments when one's customs are inconsistent with nature.
Fashion also has an effect on moral sentiment. The vices of people of high rank, such as the licentiousness of Charles VIII, are associated with the "freedom and independency, with frankness, generosity, humanity, and politeness" of the "superiors" and thus the vices are endued with these characteristics.
