“Propositions are truth-functions of elementary propositions. (An elementary proposition is a truth-function of itself.) (5)”

Ludwig Wittgenstein (1889–1951) Austrian-British philosopher

Original German: Der Satz ist eine Wahrheitsfunktion der Elementarsätze
1920s, Tractatus Logico-Philosophicus (1922)

“Philosophy must be of some use and we must take it seriously; it must clear our thoughts and so our actions. Or else it is a disposition that we have to check, and an inquiry to see that this is so; i. e. the chief proposition of philosophy is that philosophy is nonsense. And again we must then take seriously that it is nonsense, and not pretend, as Wittgenstein does, that it is important nonsense!”

Frank P. Ramsey (1903–1930) British mathematician, philosopher

"Philosophy" (1929) as quoted by Nils-Eric Sahlin, The Philosophy of F. P. Ramsey (1990)

“Notwithstanding their attacks on the basic conception of rationalism, on synthetic a priori judgments, that is, material propositions that cannot be contradicted by any experience, the empiricist posits the forms of being as constant.”

Max Horkheimer (1895–1973) German philosopher and sociologist

“Wherever Mathematics is mixed up with anything, which is outside its field, you will find attempts to demonstrate these merely conventional propositions a priori, and it will be your task to find out the false deduction in each case.”

Carl Gustav Jacob Jacobi (1804–1851) German mathematician

“[Relativist] Rel. There is a well-known proposition of Euclid which states that "Any two sides of a triangle are together greater than the third side." Can either of you tell me whether nowadays there is good reason to believe that this proposition is true?
[Pure Mathematician] Math. For my part, I am quite unable to say whether the proposition is true or not. I can deduce it by trustworthy reasoning from certain other propositions or axioms, which are supposed to be still more elementary. If these axioms are true, the proposition is true; if the axioms are not true, the proposition is not true universally. Whether the axioms are true or not I cannot say, and it is outside my province to consider.”

Arthur Stanley Eddington (1882–1944) British astrophysicist

“What you do speaks so loudly that I cannot hear what you say.”

Variant: Your actions speak so loudly, I can not hear what you are saying.

“The longer he practised his craft, the more conscious he became of the dynamic of language, of speech and writing as events in themselves. The simplest and most obvious proposition, stated in the most elementary language, could so mutate itself in the mind of the reader that it could express the opposite of what the writer had intended. What he wrote as evidence for the defence could hang the man he was defending.”

“It is perfectly obvious that the whole world is going to hell. The only possible chance that it might not is that we do not attempt to prevent it from doing so.”

“I just can’t sit while people are saying nonsense in a meeting without saying it’s nonsense.”

“Some say we need to be more patient. What we cannot, must not do is sit back and hope for the best.”
