Ludwig Wittgenstein on Truth

"To convince someone of the truth, it is not enough to state it, but rather one must find the path from error to truth."

"Like everything metaphysical the harmony between thought and reality is to be found in the grammar of the language."

"There is no more light in a genius than in any other honest man—but he has a particular kind of lens to concentrate this light into a burning point."

"A tautology's truth is certain, a proposition's possible, a contradiction's impossible."

"205. If the true is what is grounded, then the ground is not true, nor yet false."

"It is quite impossible for a proposition to state that it itself is true."

"You can't be reluctant to give up your lie and still tell the truth."

"Propositions are truth-functions of elementary propositions."

"One often makes a remark and only later sees how true it is."

"The truth can be spoken only by someone who is already at home in it; not by someone who still lives in untruthfulness, and does no more than reach out towards it from within untruthfulness."

"206. If someone asked us 'but is that true?' we might say "yes" to him; and if he demanded grounds we might say "I can't give you any grounds, but if you learn more you too will think the same."

"94. I did not get my picture of the world by satisfying myself of its correctness; nor do I have it because I am satisfied of its correctness. No: it is the inherited background against which I distinguish between true and false."

"This remark provides the key to the problem, how much truth there is in solipsism. For what the solipsist means is quite correct; only it cannot be said, but makes itself manifest. The world is my world: this is manifest in the fact that the limits of language mean the limits of my world."
