“I have been accused of a habit of changing my opinions. I am not myself in any degree ashamed of having changed my opinions. What physicist who was already active in 1900 would dream of boasting that his opinions had not changed during the last half century? In science men change their opinions when new knowledge becomes available; but philosophy in the minds of many is assimilated rather to theology than to science. The kind of philosophy that I value and have endeavoured to pursue is scientific, in the sense that there is some definite knowledge to be obtained and that new discoveries can make the admission of former error inevitable to any candid mind. For what I have said, whether early or late, I do not claim the kind of truth which theologians claim for their creeds. I claim only, at best, that the opinion expressed was a sensible one to hold at the time when it was expressed. I should be much surprised if subsequent research did not show that it needed to be modified. I hope, therefore, that whoever uses this dictionary will not suppose the remarks which it quotes to be intended as pontifical pronouncements, but only as the best I could do at the time towards the promotion of clear and accurate thinking. Clarity, above all, has been my aim.”

“When I hear another express an opinion which is not mine, I say to myself, he has a right to his opinion, as I to mine. Why should I question it? His error does me no injury, and shall I become a Don Quixote, to bring all men by force of argument to one opinion? ...Be a listener only, keep within yourself, and endeavor to establish with yourself the habit of silence, especially in politics.”

“I don't want to become obsessed with work or money or change any of the values I have now. I don't have reason to believe that I ever should change, as much as I have this feeling of urgency to pursue my dreams...”

“In America, everyone is entitled to an opinion, and it is certainly useful to have a few when a pollster shows up. But these are opinions of a quite different roder from eighteenth- or nineteenth-century opinions. It is probably more accurate to call them emotions rather than opinions, which would account for the fact that they change from week to week, as the pollsters tell us. What is happening here is that television is altering the meaning of 'being informed' by creating a species of information that might properly be called disinformation. I am using this world almost in the precise sense in which it is used by spies in the CIA or KGB. Disinformation does not mean false information. It means misleading information--misplace, irrelevant, fragmented or superficial information--information that creates the illusion of knowing something but which in fact leads one away from knowing. In saying this, I do not mean to imply that television news deliberately aims to deprive Americans of a coherent, contextual understanding of their world. I mean to say that when news is packaged as entertainment, that is the inevitable result. And in saying that the television news show entertains but does not inform, I am saying something far more serious than that we are being deprived of authentic information. I am saying we are losing our sense of what it means to be well informed. Ignorance is always correctable. But what shall we do if we take ignorance to be knowledge?”

“My own opinion is enough for me, and I claim the right to have it defended against any consensus, any majority, anywhere, any place, any time. And anyone who disagrees with this can pick a number, get in line, and kiss my ass.”

“I am, now as before, of the opinion that I did the best that I could do for my nation. I therefore do not regret my conduct and will bear the consequences that result from my conduct.”
