"The materialist, secure in the certainty of sensation, mocks at fine-spun theories, at star-gazers and dreamers, and believes that his life is solid, that he at least takes nothing for granted, but knows where he stands, and what he does. Yet how easy it is to show him, that he also is a phantom walking and working amid phantoms, and that he need only ask a question or two beyond his daily questions, to find his solid universe growing dim and impalpable before his sense."
Ralph Waldo Emerson (The Transcendentalist)
