we need to darwinize actively. In the sciences that have to do with plants, and with the rest of the animals besides man, naturalists have been so active in their darwinizing that the pre-Darwinian stuff is once for all laid by on the shelf. When man, however, engages on the subject of his noble self, the tendency still is to say: We accept Darwinism so long as it is not allowed to count, so long as we may go on believing the same old stuff in the same old way.
