VI. The Age of Kant and Goethe

It is, namely, absolutely certain that in following merely mechanical principles of nature we cannot even become sufficiently acquainted with organisms and their inner possibility, much less explain them.

Such a knowledge must, on the contrary, be altogether denied to man.
