Murray Rothbard on human uniqueness and human progress

One of the most important facts about human nature is the great diversity among individuals... Each person is unique in his tastes, interests, abilities, and chosen activities. Animal activities, routine and guided by instinct, tend to be uniform and alike. But human individuals, despite similarities in ends and values, despite mutual influences, tend to express the unique imprint of the individual’s own personality. The development of individual variety tends to be both the cause and the effect of the progress of civilization. As civilization progresses, there is more opportunity for the development of a person’s reasoning and tastes in a growing variety of fields. And from such opportunities come the advancement of knowledge and progress which in turn add to the society’s civilization. Furthermore, it is the variety of individual interests and talents that permits the growth of specialization and division of labor, on which civilized economies depend.
