I only know two very real evils in life: remorse and illness. The only good is the absence of those evils. To live for myself avoiding those two evils is my whole philosophy now.

Context

““ Yes, we know that, but the harm I am conscious of in myself is something I cannot inflict on others, ” said Prince Andrew, growing more and more animated and evidently wishing to express his new outlook to Pierre. He spoke in French. I only know two very real evils in life: remorse and illness. The only good is the absence of those evils. To live for myself avoiding those two evils is my whole philosophy now. “ And love of one’s neighbor, and self-sacrifice? ” began Pierre. “ No, I can’t agree with you! To live only so as not to do evil and not to have to repent is not enough. I lived like that, I lived for myself and ruined my life.” source
