Man Can Learn Nothing Unless He Proceeds

The Fact That Knowledge Endlessly Recedes As The Investigator Is About To Grasp It Is What Constitutes At The Same Time His Torment And Happiness.

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.

Even Mistaken Hypotheses And Theories Are Of Use In Leading To Discoveries. This Remark Is True In All The Sciences. The Alchemists Founded Chemistry By Pursuing Chimerical Problems And Theories Which Are False. In Physical Science, Which Is More Advanced Than Biology, We Might Still Cite Men Of Science Who Make Great Discoveries By Relying On False Theories.

It Is What We Know Already That Often Prevents Us From Learning.

Particular Facts Are Never Scientific; Only Generalization Can Establish Science.
