Science Starts With Preconception, With The Common Culture, And With Common Sense. It Moves On To Observation, Is Marked By The Discovery Of Paradox, And Is Then Concerned With The Correction Of Preconception. It Moves Then To Use These Corrections For The Designing Of Further Observation And For More Refined Experiment. And As It Moves Along This Course The Nature Of The Evidence And Experience That Nourish It Becomes More And More Unfamiliar; It Is Not Just The Language That Is Strange [to Common Culture].
