“A monk should surely love his books with humility, wishing their good and not the glory of his own curiosity; but what the temptation of adultery is for laymen and the yearning for riches is for secular ecclesiastics, the seduction of knowledge is for monks.”

“I felt like poisoning a monk.”

“On sober reflection, I find few reasons for publishing my Italian version of an obscure, neo-Gothic French version of a seventeenth century Latin edition of a work written in Latin by a German Monk toward the end of the fourteenth century...First of all, what style should I employ?”

“There, I said to myself, are the reasons for the silence and darkness that surround the library: it is the preserve of learning but can maintain this learning unsullied only if it prevents its reaching anyone at all, even the monks themselves. Learning is not like a coin, which remains whole even through the most infamous transactions; it is, rather, like a very handsome dress, which is worn out through use and ostentation. Is not a book like that, in fact?”

“There must be a connection between the lust for power and impotentia coeundi. I liked Marx, I was sure that he and his Jenny had made love merrily. You can feel it in the easy pace of his prose and in his humor. On the other hand, I remember remarking one day in the corridors of the university that if you screwed Krupskaya all the time, you'd end up writing a lousy book like Materialism and Empiriocriticism.”

“You always want someone to hate in order to feel justified in your own misery. Hatred is the true primordial passion. It is love that’s abnormal. That is why Christ was killed: he spoke against nature. You don’t love someone for your whole life - that impossible hope is the source of adultery, matricide, betrayal of friends … But you can hate someone for your whole life - provided he’s always there to keep your hatred alive. Hatred warms the heart.”

“I dared, for the first and last time in my life, to express a theological conclusion: "But how can a necessary being exist totally polluted with the possible? What difference is there, then, between God and primogenial chaos? Isn't affirming God's absolute omnipotence and His absolute freedom with regard to His own choices tantamount to demonstrating that God does not exist?”
