“Religion, in its purity, is not so much a pursuit as a temper; or rather it is a temper, leading to the pursuit of all that is high and holy. Its foundation is faith; its action, works; its temper, holiness; its aim, obedience to God in improvement of self, and benevolence to men.”

Autobiography (1936; 1949; 1958)
Context: Organised religion allying itself to theology and often more concerned with its vested interests than with the things of the spirit encourages a temper which is the very opposite of science. It produces narrowness and intolerance, credulity and superstition, emotionalism and irrationalism. It tends to close and limit the mind of man and to produce a temper of a dependent, unfree person.
Even if God did not exist, it would be necessary to invent Him, so Voltaire, said … perhaps that is true, and indeed the mind of man has always been trying to fashion some such mental image or conception which grew with the mind's growth. But there is something also in the reverse proposition: even if God exist, it may be desirable not to look up to Him or to rely upon Him. Too much dependence on supernatural forces may lead, and has often led, to loss of self-reliance in man, and to a blunting of his capacity and creative ability. And yet some faith seems necessary in things of the spirit which are beyond the scope of our physical world, some reliance on moral, spiritual, and idealistic conceptions, or else we have no anchorage, no objectives or purpose in life. Whether we believe in God or not, it is impossible not to believe in something, whether we call it a creative life-giving force, or vital energy inherent in matter which gives it its capacity for self-movement and change and growth, or by some other name, something that is as real, though elusive, as life is real when contrasted with death. <!-- p. 524 (1946)

Context: Because the peculiarity of man is that his machinery for reaction on external things has involved an imaginative transcript of these things, which is preserved and suspended in his fancy; and the interest and beauty of this inward landscape, rather than any fortunes that may await his body in the outer world, constitute his proper happiness. By their mind, its scope, quality, and temper, we estimate men, for by the mind only do we exist as men, and are more than so many storage-batteries for material energy. Let us therefore be frankly human. Let us be content to live in the mind.
