The task of thought in our time is to replace the lost religious and metaphysical foundation of morals by a secular and naturalistic foundation. - Walter Terence Stace

All religious thought and speech are through and through symbolic. And this fundamental insight is perhaps as old as religion itself.

The most important, the central characteristic in which all fully developed mystical experiences agree, and which in the last analysis is definitive of them and serves to mark them off from all other kinds of experiences, is that they involve the apprehension of an ultimate nonsensuous unity in all things, a oneness or a One to which neither the sense nor the reason can penetrate.

It must now be added that these attempts at proof not only fail of their purpose, and so do no good to religion, but that they positively degrade it.
