“Books should to one of these four ends conduce,
For wisdom, piety, delight, or use.”

The Figure a Poem Makes (1939)
Variant: A poem begins in delight and ends in wisdom.
Context: It should be of the pleasure of a poem itself to tell how it can. The figure a poem makes. It begins in delight and ends in wisdom. The figure is the same for love.

Sermon 37 "The Nature of Enthusiasm"
Sermons on Several Occasions (1771)
Context: Beware, lastly, of imagining you shall obtain the end without using the means conducive to it. God can give the end without any means at all; but you have no reason to think He will. Therefore constantly and carefully use all those means which He has appointed to be the ordinary channels of His grace. Use every means which either reason or Scripture recommends, as conducive (through the free love of God in Christ) either to the obtaining or increasing any of the gifts of God. Thus expect a daily growth in that pure and holy religion which the world always did, and always will, call “enthusiasm;” but which, to all who are saved from real enthusiasm, from merely nominal Christianity, is “the wisdom of God, and the power of God;” the glorious image of the Most High; “righteousness and peace;” a “fountain of living water, springing up into everlasting life!”

The portion of "The figure a poem makes. It begins in delight and ends in wisdom." is often misquoted as: Poetry begins in delight and ends in wisdom.
The Figure a Poem Makes (1939)
Context: It should be of the pleasure of a poem itself to tell how it can. The figure a poem makes. It begins in delight and ends in wisdom. The figure is the same as for love. No one can really hold that the ecstasy should be static and stand still in one place. It begins in delight, it inclines to the impulse, it assumes direction with the first line laid down, it runs a course of lucky events, and ends in a clarification of life-not necessarily a great clarification, such as sects and cults are founded on, but in a momentary stay against confusion. It has denouement. It has an outcome that though unforeseen was predestined from the first image of the original mood-and indeed from the very mood. It is but a trick poem and no poem at all if the best of it was thought of first and saved for the last. It finds its own name as it goes and discovers the best waiting for it in some final phrase at once wise and sad-the happy-sad blend of the drinking song.

Context: Oh how delightful is the taste of wisdom to those who are thus steeped in it from its very fount and origin. They who have not tried this cannot feel the delight of wisdom, just as a sick man cannot estimate the flavour of food. But because they are affected with this sort of mental sickness, and their intellect in this matter is as it were deaf from their very birth, so as not to appreciate the delight of harmony, on this account they grieve not at this so great loss of wisdom, though indeed without doubt it is an infinite loss.

Context: Books permit us to voyage through time, to tap the wisdom of our ancestors. The library connects us with the insights and knowledge, painfully extracted from Nature, of the greatest minds that ever were, with the best teachers, drawn from the entire planet and from all of our history, to instruct us without tiring, and to inspire us to make our own contribution to the collective knowledge of the human species. Public libraries depend on voluntary contributions. I think the health of our civilization, the depth of our awareness about the underpinnings of our culture and our concern for the future can all be tested by how well we support our libraries.
