“No man — prince, peasant, pope, — has all the light, who says else is a mountebank. I claim no private lien on truth, only a liberty to seek it, prove it in debate, and to be wrong a thousand times to reach a single rightness.”

“Rights give rise to legal claims. Ultimately, the more rights animals are granted, the greater the legal lien exercised on their behalf against the liberty and property of people.”

“The man who is unprincipled in private life will never make a good public servant, nor will one who is of no account at home prove a man of light and leading with the embassy in Macedonia; for he has only changed his abode, not his nature.”

“Only those afraid of the truth seek to silence debate, intimidate those with whom they disagree, or slander their ideological counterparts. Those who know they are right have no reason to stifle debate because they realize that all opposing arguments will ultimately be overcome by fact.”

“For history, I say again, has this and this only for its own: if a man will start upon it, he must sacrifice to no God but Truth; he must neglect all else; his sole rule and unerring guide is this – to think not of those who are listening to him now, but of the yet unborn who shall seek his converse.”

“No amount of experimentation can ever prove me right; a single experiment can prove me wrong.”

“Innocence has a single voice that can only say over and over again, "I didn't do it." Guilt has a thousand voices, all of them lies.”

“The only man who has the right to say that he is justified by grace alone is the man who has left all to follow Christ.”

“Let the seeking man reach a place where life and lips join to say continually, "Be thou exalted," and a thousand minor problems will be solved at once.”

“We study the glory of God, and the honour and liberty of parliament, for which we unanimously fight, without seeking our own interests… I profess I could never satisfy myself on the justness of this war, but from the authority of the parliament to maintain itself in its rights; and in this cause I hope to prove myself an honest man and single-hearted.”
