“Most of the propositions and questions to be found in philosophical works are not false but nonsensical.”

“In philosophy it is always good to put a question instead of an answer to a question. For an answer to the philosophical question may easily be unfair; disposing of it by means of another question is not.”

“Der Zweck der Philosophie ist die logische Klärung der Gedanken.Die Philosophie ist keine Lehre, sondern eine Tätigkeit.Ein philosophisches Werk besteht wesentlich aus Erläuterungen.Das Resultat der Philosophie sind nicht »philosophische Sätze«, sondern das Klarwerden von Sätzen.Die Philosophie soll die Gedanken, die sonst, gleichsam, trübe und verschwommen sind, klar machen und scharf abgrenzen.4.112The object of philosophy is the logical clarification of thoughts.Philosophy is not a theory but an activity.A philosophical work consists essentially of elucidations.The result of philosophy is not a number of "philosophical propositions", but to make propositions clear.Philosophy should make clear and delimit sharply the thoughts which otherwise are, as it were, opaque and blurred.”

“A serious and good philosophical work could be written consisting entirely of jokes.”

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

“Don't for heaven's sake, be afraid of talking nonsense! But you must pay attention to your nonsense.”

“The philosopher is not a citizen of any community of ideas, that is what makes him a philosopher.”
