Nature, as man has always known it, he knows no more. Since he has learned to esteem signs above symbols, to suppress his emotional reactions in favor of practical ones and make use of nature instead of holding so much of it sacred, he has altered the face, if not the heart, of reality.

The power of understanding symbols, i.e. of regarding everything about a sense-datum as irrelevant except a certain form that it embodies, is the most characteristic mental trait of mankind.
