Catherine Rowett quote: “Philosophy asks for a reason, not just a scientific fact.”

“The philosophy of science is concerned with how you decide if a scientific finding is correct or true. You have to establish criteria to determine if the finding or theory is valid. Validity is a fundamental problem in the philosophy of science, but the fundamental problem in the philosophy of scientific administration is the question of value. Two scientific activities are equally valid if they achieve results that are true. Now, how do you decide which activity is more valuable? The question of value is the basic question that the scientific administrator asks so that decisions can be made about funding priorities.”

Alvin M. Weinberg (1915–2006) American nuclear physicist

“Scientific inquiry shouldn't stop just because a reasonable explanation has apparently been found.”

“All that progressives ask or desire is permission — in an era when "development," "evolution," is the scientific word — to interpret the Constitution according to the Darwinian principle; all they ask is recognition of the fact that a nation is a living thing and not a machine.”

Woodrow Wilson (1856–1924) American politician, 28th president of the United States (in office from 1913 to 1921)

“Logic is the last scientific ingredient of Philosophy; its extraction leaves behind only a confusion of non-scientific, pseudo problems.”

“When I have asked thinking men what reason they had to believe that every fact in the universe is precisely determined by law, the first answer has usually been that the proposition is a "presupposition " or postulate of scientific reasoning. Well, if that is the best that can be said for it, the belief is doomed. Suppose it be " postulated " : that does not make it true, nor so much as afford the slightest rational motive for yielding it any credence.”

Charles Sanders Peirce (1839–1914) American philosopher, logician, mathematician, and scientist

The Doctrine of Necessity Examined (1892)
Context: When I have asked thinking men what reason they had to believe that every fact in the universe is precisely determined by law, the first answer has usually been that the proposition is a "presupposition " or postulate of scientific reasoning. Well, if that is the best that can be said for it, the belief is doomed. Suppose it be " postulated " : that does not make it true, nor so much as afford the slightest rational motive for yielding it any credence. It is as if a man should come to borrow money, and when asked for his security, should reply he "postulated " the loan. To "postulate" a proposition is no more than to hope it is true. There are, indeed, practical emergencies in which we act upon assumptions of certain propositions as true, because if they are not so, it can make no difference how we act. But all such propositions I take to be hypotheses of individual facts. For it is manifest that no universal principle can in its universality be compromised in a special case or can be requisite for the validity of any ordinary inference.
