“Perhaps the best illustration of the current misconceptions of the individualism of Adam Smith and his group is the common belief that they have invented the bogey of the “economic man” and that their conclusions are vitiated by their assumption of a strictly rational behavior or generally by a false rationalistic psychology. They were, of course, very far from assuming anything of the kind. It would be nearer the truth to say that in their view man was by nature lazy and indolent, improvident and wasteful, and that it was only by the force of circumstances that he could be made to behave economically or carefully to adjust his means to his ends. But even this would be unjust to the very complex and realistic view which these men took of human nature. Since it has become fashionable to deride Smith and his contemporaries for their supposedly erroneous psychology, I may perhaps venture the opinion that for all practical purposes we can still learn more about the behavior of men from the Wealth of Nations than from most of the more pretentious modern treatises on “social psychology.”
However that may be, the main point about which there can be little doubt is that Smith’s chief concern was not so much with what man might occasionally achieve when he was at his best but that he should have as little opportunity as possible to do harm when he was at his worst. It would scarcely be too much to claim that the main merit of the individualism which he and his contemporaries advocated is that it is a system under which bad men can do least harm. It is a social system which does not depend for its functioning on our finding good men for running it, or on all men becoming better than they now are, but which makes use of men in all their given variety and complexity, sometimes good and sometimes bad, sometimes intelligent and more often stupid. Their aim was a system under which it should be possible to grant freedom to all, instead of restricting it, as their French contemporaries wished, to “the good and the wise.””
