A man's ethical behavior should be based effectually on sympathy, education, and social ties; no religious basis is necessary. Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death.
Albert Einstein
False facts are highly injurious to the progress of science, for they often endure long; but false views, if supported by some evidence, do little harm, for every one takes a salutary pleasure in proving their falseness.
Charles Darwin
The aphorism in which I am the first master among Germans, are the forms of "eternity"; my ambition is to say in ten sentences what everyone else says in a book - what everyone else does not say in a book.
Friedrich Nietzsche
There is no greater fallacy than the belief that aims and purposes are one thing, while methods and tactics are another.
Emma Goldman
There have been tyrants and murderers and for a time they seem invincible but in the end, they always fall -- think of it, ALWAYS.
Mohandas Karamchand Gandhi
An honest man in politics shines more there than he would elsewhere.
Mark Twain
Most of our so-called reasoning consists in finding arguments for going on believing as we already do.
James Harvey Robinson
No two people see the external world in exactly the same way. To every separate person a thing is what he thinks it is – in other words, not a thing, but a think.
Penelope Fitzgerald
It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.
Sir Arthur Conan Doyle
Intellectual ‘work’ is misnamed; it is a pleasure, a dissipation, and is its own highest reward.
Mark Twain
We get the belief in the old age of mankind, the belief, at all times harmful, that we are late survivals, mere epigoni.
Nietzsche
The most advanced methods of science and rational calculation in the hands of a social system that is at odds with human needs produce nothing but irrationality; the more advanced the science and the more rational the calculations, the more swiftly and calamitously is this irrationality engendered. Like Captain Ahab, the capitalists say, “all my means are sane, my motives and object mad.”
Harry Braverman
An aphorism is a generalization of sorts, and our present-day writers seem more at home with the particular.
