“I tell them that if they will occupy themselves with the study of mathematics they will find in it the best remedy against the lusts of the flesh.”

“Isn't it grand, isn't it good, that language has only one word for everything we associate with love - from utter sanctity to the most fleshly lust? The result is perfect clarity in ambiguity, for love cannot be disembodied even in its most sanctified forms, nor is it without sanctity even at its most fleshly. Love is always simply itself, both as a subtle affirmation of life and as the highest passion; love is our sympathy with organic life.”

“I hope that you have nothing against malice, my good engineer. In my eyes it is the brightest sword that reason has against the powers of darkness and ugliness. Malice, sir, is the spirit of criticism, and criticism marks the origin of progress and enlightenment.”

“You Christians studied them,” Settembrini exclaimed, “studied the classical poets and philosophers until you broke out in a sweat, attempted to make their precious heritage your own, just as you used the stones of their ancient edifices for your meeting houses. Because you were well aware that no new art could come from your own proletarian souls and hoped to defeat antiquity with its own weapon. And so it will be again, so it will always be. And you with your crude visions of a new morning will likewise have to be taught by those whom—so at least you would like to persuade yourselves, and others—you despise. For without education you cannot prevail before humanity, and there is only one kind of education—you call it bourgeois, but in fact it is human.”

“Consciousness of self was an inherent function of matter once it was organized as life, and if that function was enhanced it turned against the organism that bore it, strove to fathom and explain the very phenomenon that produced it, a hope-filled and hopeless striving of life to comprehend itself, as if nature were rummaging to find itself in itself - ultimately to no avail, since nature cannot be reduced to comprehension, nor in the end can life listen to itself.”

“For I must tell you that we artists cannot tread the path of Beauty without Eros keeping company with us and appointing himself as our guide.”

“Disease, and most specially opprobrious, suppressed, secret disease, creates a certain critical opposition to the world, to mediocre life, disposes a man to be obstinate and ironical toward civil order, so that he seeks refuge in free thought, in books, in study.”
