Definition of Emotion

It is a postulate implicit in all metaphysical poetry that nothing is ineffable, that the most rarefied feeling can be exact and exactly expressed. If you cease to be able to express feelings, you cease to be able to have them, and sensibility is replaced by sentiment, in the end by the vague expression of the vague, and poetry degenerates into a diversity of noises.

[T. S. Eliot, The Varieties of Metaphysical Poetry, 200]
