The sight of a planet through a telescope is worth all the course on astronomy; the shock of the electric spark in the elbow outvalues all theories; the taste of the nitrous oxide, the firing of an artificial volcano, are better than volumes of chemistry.

Postpone not your life.

The tempered light of the woods is like a perpetual morning.

Are you not scared by seeing that the gypsies are more attractive to us than the apostles?

There is no chance and anarchy in the universe. All is system and gradation. Every god is there sitting in his sphere.
