It would be a miscomprehension to believe that because we say that a modern version of philosophy must rest on science, we mean that science alone is to be its foundation. That would be quite wrong. For it must not, need not, and cannot desert its other traditional bases such as mysticism, religion, art, and the teaching of bygone sages.
