Giacomo Casanova (Jacques Casanova de Seingal)

Even if astrology had been a real science, I knew nothing about it. We find countless events in real history which would never have occurred if they had not been predicted. This is because we are the authors of our so-called destiny, and all the 'antecedent necessities' of the Stoics are chimerical; the argument which proves the power of destiny seems strong only because it is sophistical. Cicero laughed at it. Someone whom he had invited to dinner, who had promised to go, and who had not appeared, wrote to him that since he had not gone it was evident that he had not been iturus ('going to go'). Cicero answers him: Veni ergo cras, et veni etiamsi venturus non sis ('Then come tomorrow, and come even if you are not going to come'). At this date, when I am conscious that I rely entirely on my common sense, I owe this explanation to my reader, despite the axiom, Fata viam inveniunt ('Destiny finds the way'). If the fatalists are obliged by their own philosophy to consider the concatenation of all events necessary, a parte ante ('a priori'), what remains of man's moral freedom is nothing; and in that case he can neither earn merit nor incur guilt. I cannot in conscience admit that I am a machine.

I have written the history of my life, and I have a perfect right to do so; but am I wise in throwing it before a public of which I know nothing but evil? No, I am aware it is sheer folly, but I want to be busy, I want to laugh, and why should I deny myself this gratification?

Man is free; yet we must not suppose that he is at liberty to do everything he pleases, for he becomes a slave the moment he allows his actions to be ruled by passion. The man who has sufficient power over himself to wait until his nature has recovered its even balance is the truly wise man, but such beings are seldom met with.
