Man Can Learn Nothing Unless He Proceeds

But While I Accept Specialization In The Practice, I Reject It Utterly In The Theory Of Science.

To Be Worthy Of The Name, An Experimenter Must Be At Once Theorist And Practitioner. While He Must Completely Master The Art Of Establishing Experimental Facts, Which Are The Materials Of Science, He Must Also Clearly Understand The Scientific Principles Which Guide His Reasoning Through The Varied Experimental Study Of Natural Phenomena. We Cannot Separate These Two Things: Head And Hand. An Able Hand, Without A Head To Direct It, Is A Blind Tool; The Head Is Powerless Without Its Executive Hand.

Men Who Have Excessive Faith In Their Theories ... Make Poor Observations, Because They Choose Among The Results Of Their Experiments Only What Suits Their Object, Neglecting Whatever Is Unrelated To It And Carefully Setting Aside Everything Which Might Tend Toward The Idea They Wish To Combat

Science Increases Our Power In Proportion As It Lowers Our Pride.

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.
