Society lives by faith, and develops by science....

I'm not interested in age. People who tell me their age are silly. You're as old as you feel.

Let us be true: this is the highest maxim of art and of life, the secret of eloquence and of virtue, and of all moral authority.

To know how to suggest is the great art of teaching. To attain it we must be able to guess what will interest we must learn to read the childish soul as we might a piece of music. Then, by simply changing the key, we keep up the attraction and vary the song.

The credit of advancing science has always been due to individuals and never to the age.
