If there is something you men cannot understand, you either imagine that it is spiritual or that it does not exist. Both conclusions are quite false. The proof of this is the fact that there are perhaps a million things in the universe which you would need a million quite different organs to know. Myself, for example, I know from my senses what attracts the lodestone to the pole, how the tides pull the sea, what becomes of an animal after its death.
The Demon of Socrates, in Cyrano de Bergerac's Comical History of the States and Empires of the Moon, 1656
