Philosophy is not a theory but an activity.
Ludwig Wittgenstein

The real discovery is the one which enables me to stop doing philosophy when I want to. The one that gives philosophy peace, so that it is no longer tormented by questions which bring itself into question.
Ludwig Wittgenstein

Philosophy is like trying to open a safe with a combination lock: each little adjustment of the dials seems to achieve nothing, only when everything is in place does the door open.
Ludwig Wittgenstein

Philosophy is a battle against the bewitchment of our intelligence by means of language.
Ludwig Wittgenstein

What is your aim in philosophy? To show the fly the way out of the fly-bottle.
Ludwig Wittgenstein

I set forth a humble and inglorious life; that does not matter. You can tie up all moral philosophy with a common and private life just as well as with a life of richer stuff. Each man bears the entire form of man's estate.
Michel de Montaigne

My pitching philosophy is simple - keep the ball way from the bat.
Satchel Paige

It is possible to be a master in false philosophy, easier, in fact, than to be a master in the truth, because a false philosophy can be made as simple and consistent as one pleases.
George Santayana

The philosophy of the common man is an old wife that gives him no pleasure, yet he cannot live without her, and resents any aspersions that strangers may cast on her character.
George Santayana

The love of all-inclusiveness is as dangerous in philosophy as in art.
George Santayana

The hunger for facile wisdom is the root of all false philosophy.
George Santayana

Science is what you know, philosophy is what you don't know.
Bertrand Russell

Dogmatism and skepticism are both, in a sense, absolute philosophies; one is certain of knowing, the other of not knowing. What philosophy should dissipate is certainty, whether of knowledge or ignorance.
Bertrand Russell

The point of philosophy is to start with something so simple as not to seem worth stating, and to end with something so paradoxical that no one will believe it.
Bertrand Russell

I think we ought always to entertain our opinions with some measure of doubt. I shouldn't wish people dogmatically to believe any philosophy, not even mine.
Bertrand Russell

To teach how to live without certainty and yet without being paralysed by hesitation is perhaps the chief thing that philosophy, in our age, can do for those who study it.
Bertrand Russell

The theoretical understanding of the world, which is the aim of philosophy, is not a matter of great practical importance to animals, or to savages, or even to most civilised men.
Bertrand Russell

I remain convinced that obstinate addiction to ordinary language in our private thoughts is one of the main obstacles to progress in philosophy.
Bertrand Russell

The history of philosophy is to a great extent that of a certain clash of human temperaments.
William James

There is no heresy or no philosophy which is so abhorrent to the church as a human being.
James Joyce
