Conservatism is not an economic theory, though it has economic implications. The shoe is precisely on the other foot: it is Socialism that subordinates all other considerations to man's material well-being. It is Conservatism that puts material things in their proper place --that has a structured view of the human being and of human society, in which economics plays only a subsidiary role.
The root difference between Conservatives and the Liberals of today is that Conservatives take account of the whole man, while the Liberals tend to look only at the material side of man's nature. The Conservative believes that man is, in part, an economic, an animal creature; but that he is also a spiritual creature with spiritual needs and spiritual desires. What is more, these needs and desires reflect the superior part of man's nature, and thus take precedence over his economic wants. Conservatism therefore looks upon the enhancement of man's spiritual nature as the primary concern of political philosophy. Liberals, on the other hand, --in the name of a concern for "human beings"-- regard the satisfaction of economic wants as the dominant mission of society. They are, moreover, in a hurry. So that their characteristic approach is to harness the society's political and economic forces into a collective effort to compel "progress." In this approach I believe they fight against Nature.
