"I believe I am not interested to know whether Vivisection produces results that are profitable to the human race or doesn't. To know that the results are profitable to the race would not remove my hostility to it. The pains which it inflicts upon unconsenting animals is the basis of my enmity towards it, and it is to me sufficient justification of the enmity without looking further. It is so distinctly a matter of feeling with me, and is so strong and so deeply-rooted in my make and constitution, that I am sure I could not even see a vivisector vivisected with anything more than a sort of qualified satisfaction."

“"It has become a sarcastic proverb that a thing must be true if you saw it in a newspaper. That is the opinion intelligent people have of that lying vehicle in a nutshell. But the trouble is that the stupid people–who constitute the grand overwhelming majority of this and all other nations–do believe and are moulded and convinced by what they get out of a newspaper, and there is where the harm lies."... "That awful power, the public opinion of a nation, is created in America by a horde of ignorant, self-complacent simpletons who failed at ditching and shoemaking and fetched up in journalism on their way to the poorhouse."”

“It [the press] has scoffed at religion till it has made scoffing popular. It has defended official criminals, on party pretexts, until it has created a United States Senate whose members are incapable of determining what crime against law and the dignity of their own body is—they are so morally blind—and it has made light of dishonesty till we have as a result a Congress which contracts to work for a certain sum and then deliberately steals additional wages out of the public pocket and is pained and surprised that anybody should worry about a little thing like that.”

“Is not this insanity plea becoming rather common? Is it not so common that the reader confidently expects to see it offered in every criminal case that comes before the courts? [...] Really, what we want now, is not laws against crime, but a law against insanity.”

“Get your facts first, and then you can distort them as much as you like.”

“The humorous story is told gravely; the teller does his best to conceal the fact that he even dimly suspects that there is anything funny about it.”

“In the first place God made idiots. This was for practice. Then He made School Boards.”
