I do not mean to say that formal economic analysis is worthless, and that anybody's opinion on economic matters is as good as anyone else's. On the contrary! I am a strong believer in the importance of models, which are to our minds what spear-throwers were to stone age arms: they greatly extend the power and range of our insight. In particular, I have no sympathy for those people who criticize the unrealistic simplifications of model-builders, and imagine that they achieve greater sophistication by avoiding stating their assumptions clearly. The point is to realize that economic models are metaphors, not truth. By all means express your thoughts in models, as pretty as possible (more on that below). But always remember that you may have gotten the metaphor wrong, and that someone else with a different metaphor may be seeing something that you are missing.

The particular conception of ideology operates primarily with a psychology of interests, while the total conception uses a more formal functional analysis, without any reference to motivations, confining itself to an objective description of the structural differences in minds operating in different social settings. The former assumes that this or that interest is the cause of a given lie or deception. The latter presupposes simply that there is a correspondence between a given social situation and a given perspective, point of view, or apperception mass. In this case, while an analysis of constellations of interests may often be necessary it is not to establish causal connections but to characterize the total situation. Thus interest psychology tends to be displaced by an analysis of the correspondence between the situation to be known and the forms of knowledge.

The predictions of physical theories for the most part concern situations where initial conditions can be precisely specified. If such initial conditions are not found in nature, they can be arranged. Such arrangements are considerably easier to realize with inanimate than with animate matter, because the properties of animate matter are much more sensitive to being tampered with than inanimate matter. In particular, living tissue in vitro may behave quite differently than in situ. Controlled biological experiments are, of course, possible, but they are more difficult and their scope is more limited than that of physical experiments. For this reason, biology has had to depend to a greater extent than physics on theories of larger speculative scope, in which reasoning by imaginative analogy plays a more important role.

The unremitting division of labour resulted in admirable levels of productivity. The company's success appeared to bear out the principles of efficiency laid down at the turn of the twentieth century by the Italian economist Vilfredo Pareto, who theorized that a society would grow wealthy to the extent that its members forfeited general knowledge in favour of fostering individual ability in narrowly constricted fields. In an ideal Paretan economy, jobs would be ever more finely subdivided to allow for the accumulation of complex skills, which would then be traded among workers. ... But however great the economic advantages of segmenting the elements of an afternoon's work into a range of forty-year-long careers, there was reason to wonder about the unintended side effects of doing so. In particular, one felt tempted to ask ... how meaningful the lives might feel as a result.

Do you believe in God, Andrei? No. Neither do I. But that's a favorite question of mine. An upside-down question, you know. What do you mean? Well, if I asked people whether they believed in life, they'd never understand what I meant. It's a bad question. It can mean so much that it really means nothing. So I ask them if they believe in God. And if they say they do-then, I know they don't believe in life. Why? Because, you see, God-whatever anyone chooses to call God-is one's highest conception of the highest possible. And whoever places his highest conception above his own possibility thinks very little of himself and his life. It's a rare gift, you know, to feel reverence for your own life and to want the best, the greatest, the highest possible, here, now, for your very own. To imagine a heaven and then not to dream of it, but to demand it.

With mankind the differences between the sexes are greater than in most species of Quadrumana, but not so great as in some, for instance, the mandrill. Man on an average is considerably taller, heavier, and stronger than woman, with squarer shoulders and more plainly-pronounced muscles. ... Man is more courageous, pugnacious, and energetic than woman, and has a more inventive genius. His brain is absolutely larger, but whether relatively to the larger size of his body, in comparison with that of woman, has not, I believe been fully ascertained. In woman the face is rounder; the jaws and the base of the skull smaller; the outlines of her body rounder, in parts more prominent; and her pelvis is broader than in man; but this latter character may perhaps be considered rather as a primary than a secondary sexual character. She comes to maturity at an earlier age than man.
