I hate facts. I always say the chief end of man is to form general propositions - adding that no general proposition is worth a damn.
Oliver Wendell Holmes
I hold that the propositions embodied in natural science are not derived by any definite rule from the data of experience, and that they can neither be verified nor falsified by experience according to any definite rule.
Michael Polanyi
It is thus necessary to examine all things according to their essence, to infer from every species such true and well established propositions as may assist us in the solution of metaphysical problems.
Maimonides
Let that which stood in front go behind, let that which was behind advance to the front, let bigots, fools, unclean persons, offer new propositions, let the old propositions be postponed.
Walt Whitman
Liberalism is an attitude rather than a set of dogmas - an attitude that insists upon questioning all plausible and self-evident propositions, seeking not to reject them but to find out what evidence there is to support them rather than their possible alternatives.
Morris Raphael Cohen
Not that the propositions of geometry are only approximately true, but that they remain absolutely true in regard to that Euclidean space which has been so long regarded as being the physical space of our experience.
Arthur Cayley
Now obviously the propositions of the system have reference to matters of empirical fact; if they did not, they could have no claim to be called scientific.
Talcott Parsons
One does afford oneself the luxury to come into the studio and all day, every day, spend one's life making aesthetic propositions. What an immense luxury.
Anish Kapoor
Propositions show what they say: tautologies and contradictions show that they say nothing.
Ludwig Wittgenstein
That is, a system starts with a group of interrelated propositions which involve reference to empirical observations within the logical framework of the propositions in question.
Talcott Parsons
The first, or theoretic branch, that which explains the nature, production, and distribution of wealth, will be found to rest on a very few general propositions, which are the result of observation, or consciousness.
Nassau William Senior
True science is never speculative; it employs hypotheses as suggesting points for inquiry, but it never adopts the hypotheses as though they were demonstrated propositions.
Cleveland Abbe
