Theodore Roszak on William Blake

“Blake deeply admired science; he never failed to portray it heroically. But he was concerned that science saw the universe from an odd angle that hid as much as it revealed. Science screened the value of things, the beauty of things, the sacredness of things as if these qualities might not really be there. Blake called this Single Vision, and contrasted it with his ideal Fourfold vision: an understanding that included the poetic, the sensuous, and the visionary along with the rational. ...he fervently prayed for our culture to be saved from the scientist's severe abbreviation of reality: "God us keep from Single Vision and Newton's Sleep."”

“Freud was frank to admit that Romantic artists like Blake had discovered the unconscious before he had. But... he could hardly adopt Blake's unsettling view of the scientific psyche.”
