Health is the soul that animates all the enjoyments of life, which fade and are tasteless without it.

I know that I am intelligent, because I know that I know nothing.

I knew I belonged to the public and to the world, not because I was talented or even beautiful, but because I had never belonged to anything or anyone else.

Man is the only creature that refuses to be what he is.

Let us permit nature to have her way. She understands her business better than we do.
