The imagination is the spur of delights... all depends upon it, it is the mainspring of everything; now, is it not by means of the imagination one knows joy? Is it not of the imagination that the sharpest pleasures arise?

Imperious, choleric, irascible, extreme in everything, with a dissolute imagination the like of which has never been seen, atheistic to the point of fanaticism, there you have me in a nutshell, and kill me again or take me as I am, for I shall not change.

Happiness is ideal, it is the work of the imagination.

Never lose sight of the fact that all human felicity lies in man's imagination, and that he cannot think to attain it unless he heeds all his caprices. The most fortunate of persons is he who has the most means to satisfy his vagaries.

Truth titillates the imagination far less than fiction.

Nature, who for the perfect maintenance of the laws of her general equilibrium, has sometimes need of vices and sometimes of virtues, inspires now this impulse, now that one, in accordance with what she requires.
