We live amid surfaces, and the true art of life is to skate well on them

Ideas must work through the brains and the arms of good and brave men or they are no better than dreams.

Look out! Behind you!

It never was in the power of any man or any community to call the arts into being. They come to serve his actual wants, never to please his fancy.

A man must be in sympathy with society around him, or else, not wish to be in sympathy with it. If neither of these two, he must be wretched.

Insist upon yourself. Be original.

Research is not seeing what others do not see, it is seeing the same thing as other people and thinking what they do not.
