The soul is... but an empty word, of which no one has any idea, and which an enlightened man should use only to signify the part in us that thinks...

He who has the most imagination should be regarded as having the most intelligence or genius, for all these words are synonymous...

If one's organism is... the preeminent advantage, and the source of all others, education is the second. The best made brain would be a total loss without it...

Whatever the virtue may be, from whatever source it may come, it is worthy of esteem... Mind, beauty, wealth, nobility, although the children of chance, all have their own value, as skill, learning and virtue have theirs.

Man's preeminent advantage is his organism. ...Only through nature do we have any good qualities; to her we owe all that we are.

Imagination is the soul, since it plays all the roles of the soul.

Why should we divide the sensitive principle which thinks in man? ...For a thing that is divided can no longer without absurdity be regarded as indivisible.

Everything is the work of imagination, and... all the faculties of the soul can be correctly reduced to pure imagination...
