“Convince me, but without convictions. Convictions no longer convince me.”

“The patient typically finds himself impelled by some deep, inner conviction that something is true, or right, or virtuous: a conviction that doesn't seem to owe anything to evidence or reason, but which, nevertheless, he feels as totally compelling and convincing. We doctors refer to such a belief as "faith."”

“People over forty can seldom be permanently convinced of anything. At eighteen our convictions are hills from which we look; at forty-five they are caves in which we hide.”

“He's the kind of liar who totally forgets what he told you the last time, but he believes every single lie with such conviction that sometimes he can convince you of it.”

“Conviction without experience makes for harshness.”

“Teach me to treat all that comes to me with peace of soul and with firm conviction that Your will governs all.”

“When we are convinced of some great truths, and feel our convictions keenly, we must not fear to express it, although others have said it before us. Every thought is new when an author expresses it in a manner peculiar to himself.”

“When once—which every body must be—you are convinced of the wickedness and deceit of men, it is impossible to preserve untainted your own innocence of heart. Experience will prove the depravity of mankind, and the conviction of it only serves to create distrust, suspicion—caution—and sometimes causelessly.”

“Disease is a conviction, and I was born with that conviction.”

“Someone once described me as a maverick and that's what I would say. I'm a maverick not by choice but by conviction.”
