"Perhaps not all of these people believe in that stuff about the Devil to whom one can sell one's soul; but all those who have to know something about the soul, because they draw a good income out of it as clergy, historians or artists, bear witness to the fact that it has been ruined by mathematics and that in mathematics is the source of a wicked intellect that, while making man the lord of the earth, also makes him the slave of the machine."
