Obervation Is A Passive Science, Experimentation Is

We Must Never Make Experiments To Confirm Our Ideas, But Simply To Control Them.

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.

Obervation Is A Passive Science, Experimentation Is An Active Science.

We Achieve More Than We Know. We Know More Than We Understand. We Understand More Than We Can Explain.

With The Aid Of These Active Experimental Sciences Man Becomes An Inventor Of Phenomena, A Real Foreman Of Creation; And Under This Head We Cannot Set Limits To The Power That He May Gain Over Nature Through Future Progress Of The Experimental Sciences.
