"Today political science is often said to be ‘descriptive’ or ‘empirical,’ concerned with facts; political philosophy is called ‘normative’ because it expresses values. But these terms merely repeat in more abstract form the difference between political science, which seeks agreement, and political philosophy, which seeks the best."

“The simplified notion of self-interest used by our political and social science cannot tolerate the tension between one’s own and the good, for that tension leaves human behavior unpredictable. One cannot penetrate into every individual’s private thoughts, and there is no clear way to judge among different conceptions of the good. So in order to overcome the tension, science tries to combine one’s own and the good in such a way as to preserve neither. It generalizes one’s own as the interest of an average or, better to say, predictable individual who lives his life quantifiably so as to make its study easier for the social scientist. And for the same purpose it vulgarizes the good by eliminating the high and the mighty in our souls , transforming our aspiration to nobility and truth into personal preferences of whose value science is incognizant, to which it is indifferent.”

“Science wants the fruits of science, and it does not tolerate much doubt about the goodness of those fruits. ... Scientists had a bad conscience about making the atom bomb, it’s fair to say, but their doubts were not prompted, still less endorsed by their science.”

“Self-interest, when simple, is universal; I would do the same as you. I would be propelled toward an obvious good, or toward a good I thought obvious. If self-interest is obvious, it is not really your very own; it has been generalized, perhaps artificially.”

“People want to stand for something, which means opposing those who stand for something else. In the course of opposing they will often resort to insults and name-calling, which are normal in politics though never in your interest. The demand for more civility in politics today should be directed toward improving the quality of our insults, seeking civility in wit rather than blandness.”

“Having eliminated the soul, modern science cannot understand the body in its most important aspect, which is its capacity for self-importance. Modern biology, particularly the theory of evolution, is based on the overriding concern for survival in all life. This is surely wrong in regard to human life. If you cannot look around you and must insist on indulging a taste for the primitive, you have only to visit the ruins of an ancient people and ponder how much of its GNP was devoted to religion, to its sense of the meaning of human life rather than mere survival.”

“The way out from complication and doubt is to reduce the good to pleasure, something close to the body, or to utility, something useful to the body. ... The body is considered as a factor all human beings have in common, hence an easy basis for generalization.”
