I believe, sir, in all the progress. Air navigation is the result of the oceanic navigation: from water the human has to pass in the air. Everywhere where creation will be breathable to him, the human will penetrate into the creation. Our only limit is life.

Virtue has a veil, vice a mask.

Sire, you are looking at a plain man, and I am looking at a great man. Each of us may benefit.

To learn to read is to light a fire.

Nobody loves the light like the blind man.

No man is more unhappy than the one who is never in adversity; the greatest affliction of life is never to be afflicted.

One only needs to see a smile in a white crape bonnet in order to enter the palace of dreams.
