Imagination is not something apart and hermetic, not a way of leaving reality behind; it is a way of engaging reality.

Were it not for imagination a man would be as happy in the arms of a chambermaid as of a duchess.

Almost any man may like the spider spin from his own inwards his own airy citadel.

Heard melodies are sweet, but those unheard Are sweeter.

The problems of the world cannot possibly be solved by skeptics or cynics whose horizons are limited by the obvious realities. We need men who can dream of things that never were.

Imagination is the mad boarder.

Imagination grows by exercise and contrary to common belief is more powerful in the mature than in the young.

Only imagination that towers can reproduce evanescence and render rigidity flexible.

The eyes are not responsible when the mind does the seeing.

That which we know is but little; that which we have a presentiment of is immense; it is in this direction that the poet outruns the learned man.
