“To admit uncertainty is to admit to weakness, to powerlessness, and to believe in yourself despite both. It is a frailty, but in this frailty there is a strength: the conviction to live in your own mind, and not in someone else’s.”

“Love's but a frailty of the mind,
When 'tis not with ambition joined.”

“Nothing is more intolerable than to have admit to yourself your own errors.”

“As that the walls worn thin, permit the mind
To look out thorough, and his frailty find. 1”

“Don't argue for other people's weaknesses. Don't argue for your own. When you make a mistake, admit it, correct it, and learn from it / immediately.”

“There are moments in your life when you see yourself through someone else’s eyes, when your only hope of believing you’re capable of doing something is because someone else believes it for you.”

“Scientists are just as vulnerable to wishful thinking, just as likely to be tempted by base motives, just as venal and gullible and forgetful as the rest of humankind. Scientists don't consider themselves to be saints; they don't even pretend to be priests (who according to tradition are supposed to do a better job than the rest of us at fighting off human temptation and frailty). Scientists take themselves to be just as weak and fallible as anybody else, but recognizing those very sources of error in themselves and in the groups to which they belong, they have devised elaborate systems to tie their own hands, forcibly preventing their frailties and prejudices from infecting their results.”

“Christianity is at the root of the evil that has corrupted the West. This is the truth, and it does not admit uncertainty.”

“It takes strength and courage to admit the truth.”

“I live lies because I cannot endure the weakness of anger, and I cannot admit the irrationality of love.”
