What was more needed by this old man who divided the leisure hours of his life, where he had so little leisure, between gardening in the daytime, and contemplation at night? Was not this narrow enclosure, with the sky for a background, enough to enable him to adore God in his most beautiful as well as in his most sublime works? Indeed, is not that all, and what more can be desired? A little garden to walk, and immensity to reflect upon. At his feet something to cultivate and gather; above his head something to study and meditate upon: a few flowers on the earth, and all the stars in the sky.

Great grief is a divine and terrible radiance which transfigures the wretched.

Being good is easy, what is difficult is being just.

To know, to think, to dream. That is everything.

The straight line, a respectable optical illusion which ruins many a man.
