Experiment Is Fundamentally Only Induced Observation.

When Entering On New Ground We Must Not Be Afraid To Express Even Risky Ideas So As To Stimulate Research In All Directions. As Priestley Put It, We Must Not Remain Inactive Through False Modesty Based On Fear Of Being Mistaken.

Man Does Not Limit Himself To Seeing; He Thinks And Insists On Learning The Meaning Of Phenomena Whose Existence Has Been Revealed To Him By Observation. So He Reasons, Compares Facts, Puts Questions To Them, And By The Answers Which He Extracts, Tests One By Another. This Sort Of Control, By Means Of Reasoning And Facts, Is What Constitutes Experiment, Properly Speaking; And It Is The Only Process That We Have For Teaching Ourselves About The Nature Of Things Outside Us.

In Every Enterprise ... The Mind Is Always Reasoning, And, Even When We Seem To Act Without A Motive, An Instinctive Logic Still Directs The Mind. Only We Are Not Aware Of It, Because We Begin By Reasoning Before We Know Or Say That We Are Reasoning, Just As We Begin By Speaking Before We Observe That We Are Speaking, And Just As We Begin By Seeing And Hearing Before We Know What We See Or What We Hear.

Art Is 'i'; Science Is 'we'.

Man Can Learn Nothing Unless He Proceeds From The Known To The Unknown.
