"Most scientists would make very hard work of explaining how the concept of soul fits into the material universe, where there is nothing but "atoms and the void." Was this what Blake meant when he said that science was a tree of death? The death of religion? Of imagination? Both have been frequently suggested. ...Science is certainly our prime weapon against superstition and irrationalism, but in a world in which science flourishes—with or without God—love and fear remain, as do pleasure and regret, poetry and humor, art and music. The arts are not lessened by the sciences. Blake was mistaken: man's ineradicable gift, his questing curiosity, the divine discontent, is the common source of the arts and sciences."
