“It may be considered folly by common opinion but this refusal to destroy life unnecessarily, this reverence for it, must become a deeply implanted part of his ethical standard.”
“Ethics, too, are nothing but reverence for life. This is what gives me the fundamental principle of morality, namely, that good consists in maintaining, promoting, and enhancing life, and that destroying, injuring, and limiting life are evil.”
“When considering a man's motives, remember you must not measure his wheat with your bushel. He may not be using the same standard at all.”
“The latter part of a wise person's life is occupied with curing the follies, prejudices and false opinions they contracted earlier.”
“He who considers more deeply knows that, whatever his acts and judgements may be, he is always wrong.”
“But it may be the hard part of a friend to rebuke a friend's folly.”
