Thomas Sowell, The Vision of the Anointed quote-12 應景的quote

“Evidence is fact that discriminates between one theory and another. Facts do not „speak for themselves.” they speak for or against competing theories. Theories can be devastated by facts but they can never be proven correct by facts.
What empirical verification can do is to reveal which of the competing theories currently being considered is more consistent with that which is known factually. Some other theory may come along tomorrow that is still more consistent with the facts, or explains those facts with fewer, clearer, or more manageable assumptions.”
