The work of science is to substitute facts for appearances, and demonstrations for impressions.

Volume IIIJohn Ruskin
"Bosh," he said, "On what else is the whole world run but immediate impressions? What is more practical? My friend, the philosophy of this world may be founded on facts, but its business is run on spiritual impressions and atmospheres."
Gilbert Keith Chesterton
Cosmology is a science which has only a few observable facts to work with.
Robert Woodrow Wilson
It was mathematics, the non-empirical science par excellence, wherein the mind appears to play only with itself, that turned out to be the science of sciences, delivering the key to those laws of nature and the universe that are concealed by appearances.
Hannah Arendt
Rules necessary for demonstrations. To prove all propositions, and to employ nothing for their proof but axioms fully evident of themselves, or propositions already demonstrated or admitted; Never to take advantage of the ambiguity of terms by failing mentally to substitute definitions that restrict or explain them.
Blaise Pascal
Facts and not merely opinions are what we want. Emotionalism is not a substitute for the truth.
