I have a voice, too, and for good or evil mine is the speech that cannot be silenced

Do not talk to me of Archimedes' lever. He was an absent-minded person with a mathematical imagination. Mathematics commands my respect, but I have no use for engines. Give me the right word and the right accent and I will move the world.

They talk of a man betraying his country, his friends, his sweetheart. There must be a moral bond first. All a man can betray is his conscience.

I have a voice, too, and for good or evil mine is the speech that cannot be silenced

I remember my youth and the feeling that will never come back any more /the feeling that I could last for ever, outlast the sea, the earth, and all men; the deceitful feeling that lures us on to joys, to perils, to love, to vain effort /to death; the triumphant conviction of strength, the heat of life in the handful of dust, the glow in the heart that with every year grows dim, grows cold, grows small, and expires /and expires, too soon, too soon /before life itself

All a man can betray is his conscience.

I would not unduly praise the virtue of restraint. It is often merely temperamental. But it is not always a sign of coldness. It may be pride. There can be nothing more humiliating than to see the shaft of one's emotion miss the mark of either laughter or tears. Nothing more humiliating! And this for the reason that should the mark be missed, should the open display of emotion fail to move, then it must perish unavoidably in disgust or contempt.
