“The idea has grown up that the scientific approach can alone properly be said to be intellectual, whereas the approach of religion cannot, and that therefore the tendency of religion is to impede intellectuality. This is not to be wondered at in people for whom the word "intellectuality" implies no more than conformity to the scientific approach; but if the goal of intellectuality is not a better understanding of the origin, nature and end of man and of the universe, what is it? It is just such an understanding that religion claims to offer, and in so far as that claim is justified, religion, very far from impeding intellectuality, is an essential part of it.”

Context: But the imparting of religion is not to be sought in books, like that of intellectual conceptions and scientific knowledge. The pure impression of the original product is too far destroyed in this medium, which, in the same way that dark-colored objects absorb the greatest proportion of the rays of light, swallows up everything belonging to the pious emotions of the heart, which cannot be embraced in the insufficient symbols from which it is intended again to proceed. Nay, in the written communications of religious feeling, everything needs a double and triple representation; for that which originally represented, must be represented in its turn; and yet the effect on the whole man, in its complete unity, can only be imperfectly set forth by continued and varied reflections. It is only when religion is driven out from the society of the living, that it must conceal its manifold life under the dead letter. Neither can this intercourse of heart with heart, on the deepest feelings of humanity, be carried on in common conversation.

Context: It is the business of the preacher, not only to state moral truths, but to inspire his hearers with a realising sense of their value, and to awaken in them the desire to act accordingly. He can do this only by putting his own purpose as a yeast into their hearts. The influence of the right sort of preachers cannot be spared. The human race is not yet so far advanced that it can dispense with the impulses that come from men of more than average intensity of moral energy.
Let us produce, through the efficacy of a better moral life and of a deeper moral experience, a surer faith in the ultimate victory of the good.
Let us found religion upon a basis of perfect intellectual honesty. Religion, if it is to mean anything at all, must stand for the highest truth. How then can the cause of truth be served by the sacrifice, more or less disguised, of one's intellectual convictions?

Context: The moral nature of man is more sacred in my eyes than his intellectual nature. I know they cannot be divorced — that without intelligence we should be Brutes — but it is the tendency of our gaping, wondering dispositions to give pre-eminence to those faculties which most astonish us. Strength of character seldom, if ever, astonishes; goodness, lovingness, and quiet self-sacrifice, are worth all the talents in the world.
