Finally, good sense is the body of poetic genius, fancy its drapery, motion its life, and imagination the soul that is everywhere and in each; and forms all into one graceful and intelligent whole.
When forced to work within a strict framework, the imagination is taxed to its utmost and will produce its richest ideas. Given total freedom, the work is likely to sprawl.
Imagination is a very high sort of seeing, which does not come by study, but by the intellect being where and what it sees, by sharing the path, or circuits of things through forms, and so making them translucid to others.
You can be a thorough-going Neo-Darwinian without imagination, metaphysics, poetry, conscience, or decency. For 'Natural Selection' has no moral significance: it deals with that part of evolution which has no purpose, no intelligence, and might more appropriately be called accidental selection, or better still, Unnatural Selection, since nothing is more unnatural than an accident. If it could be proved that the whole universe had been produced by such Selection, only fools and rascals could bear to live.
Most churches don't have the resources for these tricks and inducements but are still bound to the imagination that church happens on a Sunday in a building.
