Wittgenstein, Ludwig

"A picture is laid against reality like a ruler."

"Whereof we cannot think clearly, we cannot speak."

"In nature we find not prophecies of our destiny but problems to be solved."

"Man has to awaken to wonder—and so perhaps do peoples. Science is a way of sending him to sleep again."

"The problems are solved, not by giving new information, but by arranging what we have always known."

"All religious discourse is irreducibly metaphorical."

"The world exists independently of what is thought about it."

"Everything we do in philosophy must be reviewed for its practical consequences."

"You cannot solve human problems by technology and material progress alone."

"In order to tell if a line is crooked, you must have some idea of a straight line."

"The limits of language define the limits of the self."

"The more you own, the more it owns you."

"A picture holds a thousand words, but philosophy holds a thousand pictures."

"Don't think, but look! Look at the world with fresh eyes."

"The difficulty in philosophy is to say no more than we know."

"Life is not a problem to be solved but a reality to be experienced."

"Whereof one cannot speak, thereof one must be silent."

"The world of those who are happy is different from the world of the unhappy."

"An inner process stands in need of outward criteria."

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

"It is not how things are in the world that is mystical, but that it exists."

"To imagine a language means to imagine a form of life."

"The subject does not belong to the world; rather, it is a limit of the world."

"What we cannot speak about we must pass over in silence."

"Knowledge is not something to be possessed but something to be lived."

"The purpose of philosophy is to show the fly the way out of the bottle."

"Don't ask for the meaning, ask for the use."

"A man will be imprisoned in a room with an open door that he does not see."

"The facts are not the only thing that matters."

"Our language can be seen as an ancient city; a maze of little streets and squares."
