“The life of the cenobite is a human problem. When we speak of convents, those seats of error but innocence, of mistaken views but good intentions, of ignorance but devotion, of torment but martyrdom, we must nearly always say yes or no...The monastery is a renunciation. Self-sacrifice, even when misdirected, is still self-sacrifice. To assume as duty a strict error has its peculiar grandeur.”

“self-development is a higher duty than self-sacrifice.”

“For centuries, the battle of morality was fought between those who claimed that your life belongs to God and those who claimed that it belongs to your neighbors - between those who preached that the good is self-sacrifice for the sake of ghosts in heaven and those who preached that the good is self-sacrifice for the sake of incompetents on earth. And no one came to say that your life belongs to you and that the good is to live it.”

“Self-sacrifice? But it is precisely the self that cannot and must not be sacrificed.”

“One of the reasons for its success is that science has a built-in, error-correcting machinery at its very heart. Some may consider this an overbroad characterization, but to me every time we exercise self-criticism, every time we test our ideas against the outside world, we are doing science. When we are self-indulgent and uncritical, when we confuse hopes and facts, we slide into pseudoscience and superstition.”

“This is the secret of life: the self lives only by dying, finds its identity (and its happiness) only by self-forgetfulness, self-giving, self-sacrifice, and agape love.”
