Common sense is the genius of humanity.

Errors belong to libraries; truth, to the human mind.

All truths are old, and all that we have to do is recognize and utter them anew.

Gifts come from above in their own peculiar forms.

The true, prescriptive artist strives after artistic truth; the lawless artist, following blind instinct, after an appearance of naturalness. The one leads to the highest peaks of art, the other to its lowest depths.

It is only necessary to grow old to become more charitable and even indulgent. I see no fault committed by others that I have not committed myself.

I let everyone follow his own bent, that I may be free to follow mine.
