[单项选择] For most thinkers since the Greek philosophers, it was self-evident that there is something called human nature, something that constitutes the essence of man. There were various views about what constitutes it, but there was agreement that such an essence exists -- that is to say, that there is something by virtue of which man is man.

An examination of the history of humanity suggested that man in our epoch is so different from man in previous times that it seemed unrealistic to assume that men in every age have had in common something that can be called "human nature".
