I would be virtuous for my own sake, though nobody were to know it; as I would be clean for my own sake, though nobody were to see me.

The greatest of fools is he who imposes on himself, and in his greatest concern thinks certainly he knows that which he has least studied, and of which he is most profoundly ignorant.

The most natural beauty in the world is honesty and moral truth. For all beauty is truth. True features make the beauty of the face; true proportions, the beauty of architecture; true measures, the beauty of harmony and music.

True courage is cool and calm. The bravest of men have the least of a brutal, bullying insolence, and in the very time of danger are found the most serene and free.

I would be virtuous for my own sake, though nobody were to know it; as I would be clean for my own sake, though nobody were to see me.

True features make the beauty of a face, and true proportions the beauty of architecture.

It is the hardest thing in the world to be a good thinker without being a good self examiner.
