There is no trifling with nature; it is always true, grave, and severe; it is always in the light, and the faults and errors fall to our share. It defies incompetency, but reveals its secrets to the competent, the truthful, and the pure.

No wise combatant underestimates their antagonist.

Only the soul that loves is happy

Whatever you can do or dream, begin it.

The more one knows, the more one comprehends, the more one realizes that everything turns in a circle.

If you have a great work in your head, nothing else thrives near it; all other thoughts are repelled, and the pleasure of life itself is for the time lost.

What a torment it is to see so much loveliness passing and repassing before us, and yet not dare to lay hold of it!
