Quote by Wittgenstein, Richard
"A proposition has sense only if we know what would be the case if it were true."
More from Wittgenstein, Richard
"Whereof one cannot speak, thereof one must be silent."
"The limits of my language mean the limits of my world."
"A picture held us captive. And we could not get outside it, for it lay in our language and language seemed to repeat it to us inexorably."
"If you wish to leave a track in the history of the world, you must pay with your soul."
