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.

But it is not an exaggeration to say that mystical experience is everywhere unitary in the same sense that everywhere aesthetic experience is unitary. British, American, German, Indian, Chinese, Japanese art are of course very different from one another. Yet they have one root in their basic experience of beauty.

Religion can probably out live any scientific discoveries which could be made. It can accommodate itself to them. The root cause of the decay of faith has not been any particular discovery of science, but rather the general spirit of science and certain basic assumptions upon which modern science, from the seventeenth century onwards, has proceeded.
