I wish to propose a doctrine which may, I fear, appear wildly paradoxical and subversive. The doctrine in question is this: that it is undesirable to believe a proposition when there is no ground whatever for supposing it true. I must, of course, admit that if such an opinion became common it would completely transform our social life and our political system; since both are at present faultless, this must weigh against it. (Carl Sagan)

As far as I am concerned, I resign from humanity. I no longer want to be, nor can still be, a man. What should I do? Work for a social and political system, make a girl miserable? Hunt for weaknesses in philosophical systems, fight for moral and esthetic ideals? It's all too little. I renounce my humanity even though I may find myself alone. But am I not already alone in this world from which I no longer expect anything?

Emil Cioran

All the critics who could not make their reputations by discovering you are hoping to make them by predicting hopefully your approaching impotence, failure and general drying up of natural juices. Not a one will wish you luck or hope that you will keep on writing unless you have political affiliations in which case these will rally around and speak of you and Homer, Balzac, Zola and Link Steffens.

Ernest Hemingway

I can imagine no greater disservice to the country than to establish a system of censorship that would deny to the people of a free republic like our own their indisputable right to criticise their own public officials. While exercising the great powers of the office I hold, I would regret in a crisis like the one through which we are now passing to lose the benefit of patriotic and intelligent criticism.

Reporter: How many people who labor in the same musical vineyard in which you toil - how many are protest singers? That is, people who use their music, and use the songs to protest the, uh, social state in which we live today: the matter of war, the matter of crime, or whatever it might be. Bob Dylan: Uh, I think there's about, uh...136. Reporter: You say about 136, or you mean exactly 136? Bob Dylan: Uh, it's either 136 or 142.

Is not a patron, my lord, one who looks with unconcern on a man struggling for life in the water, and when he has reached ground encumbers him with help The notice which you have been pleased to take care of my labors, had it been early, had been kind but it has been delayed till I am indifferent, and cannot enjoy it till I am solitary, and cannot impart it till I am known, and do not want it.

Samuel Johnson
