“I regret,” said Valerius Maximus,[131] “to speak of the youth of Themistocles, when I see, on the one hand, his father disinheriting him with ignominy, and, on the other, his mother, from shame of such a son, hanging herself with grief.” Sallust, who wrote such beautiful tirades on virtue, passed his life in debauchery. Speusippus, the disciple of Plato, was killed in the act of adultery.[132] Democritus is said to have blinded himself because he could not look at a woman without desiring her. Aristippus, under the mask of austerity, abandoned himself to debauchery. Anaxagoras denied a deposit confided to him by strangers; Aristotle basely flattered Alexander. Theognis wrote moral maxims, particularly on a happy death, and bequeathed his patrimony to a prostitute (?), leaving his own family destitute. Euripides, Juvenal, and Aretino remarked that women of letters were nearly always licentious. Thus Sappho, Philena, and Elephantina were prostitutes, as was Leontion, philosopher and priestess, who gave herself to all the philosophers; and Demophila who told little love stories, and put them in practice. At the Renaissance, Veronica Franco, Tullia of Aragon, and other prostitutes, were as well known for their licentiousness as for their poetry. Voigt considers that immorality was a characteristic feature of the Renaissance period.[133] In my _Uomo Delinquente_ I have considered criminal genius. Sallust, Seneca, and Bacon were accused of peculation; Cremani was a forger, Demme a poisoner. One may also refer to Casanova, who was declared to have forfeited his nobility for a crime the nature of which is not known, and Avicenna, an epileptic, who in old age plunged into debauchery, and took opium in excess, so that it was said of him that philosophy had not enabled him to live honestly, nor medicine to live healthily.[134] Among poets and artists criminality is, unfortunately, well marked. Many among them are dominated by passion which becomes the most powerful spur of their activity; they are not protected by the logical criticism and judgment with which men of science are armed. This is why we must count among criminals Bonfadio, Rousseau, Aretino, Ceresa, Brunetto Latini, Franco, Foscolo, possibly Byron. Observe that I leave out of the question ancient times and barbarous countries among which brigandage and poetry went hand in hand.
