Many years ago I saw in the window of a print shop in Oxford Street a picture that I can see now with my mind’s eye. It was a drawing of a nice pink baby in nature’s garb sitting on the bare earth in a wilderness of space. Beneath the picture was some such legend as this: What? Whence? Whither? It was a clever hint of the everlasting quest of man. Ever since he found himself—that is, since he began to think—man has been asking those three questions, and he has found many answers, and the answers have varied with his knowledge of his surroundings.
