As thinkers, mankind has ever divided into two sects, Materialists and Idealists; the first class founding on experience, the second on consciousness; the first class beginning to think from the data of the senses, the second class perceive that the senses are not final and say, The senses give us representations of things, but what are the things themselves, they cannot tell. The materialist insists on facts, on history, on the force of circumstances and the animal wants of man; the idealists on the power of Thought and Will, on inspiration, on miracle, on individual culture.
Ralph Waldo Emerson
