"I say that conceit is just as natural a thing to human minds as a centre is to a circle. But little-minded people's thoughts move in such small circles that five minutes' conversation gives you an arc long enough to determine their whole curve. An arc in the movement of a large intellect does not sensibly differ from a straight line. Even if it have the third vowel as its centre, it does not soon betray it. The highest thought, that is, is the most seemingly impersonal; it does not obviously imply any individual centre."

“Time, time only, can gradually wean us from our Epeolatry, or word-worship, by spiritualizing our ideas of the thing signified.”

“Boston State-house is the hub of the solar system. You couldn't pry that out of a Boston man if you had the tire of all creation straightened out for a crow-bar.”

“I do not know in what shape the practical question may present itself to you; but I will tell you my rule in life, and I think you will find it a good one. Treat bad men exactly as if they were insane. They are in-sane, out of health, morally. Reason, which is food to sound minds, is not tolerated, still less assimilated, unless administered with the greatest caution; perhaps, not at all. Avoid collision with them, so far as you honorably can; keep your temper, if you can,—for one angry man is as good as another; restrain them from violence, promptly, completely, and with the least possible injury, just as in the case of maniacs,—and when you have got rid of them, or got them tied hand and foot so that they can do no mischief, sit down and contemplate them charitably...”

“I try his head occasionally as housewives try eggs,— give it an intellectual shake and hold it up to the light, so to speak, to see if it has life in it, actual or potential, or only contains lifeless albumen.”

“I have always considered my face a convenience rather than an ornament.”

“Insanity is often the logic of an accurate mind overtasked. Good mental machinery ought to break its own wheels and levers, if anything is thrust among them suddenly which tends to stop them or reverse their motion. A weak mind does not accumulate force enough to hurt itself; stupidity often saves a man from going mad.”
