We Must Alter Theory To Adapt It

The Stability Of The Internal Medium Is A Primary Condition For The Freedom And Independence Of Certain Living Bodies In Relation To The Environment Surrounding Them.

If I Had To Define Life In A Single Phrase, I Should Clearly Express My Thought Of Throwing Into Relief One Characteristic Which, In My Opinion, Sharply Differentiates Biological Science. I Should Say: Life Is Creation.

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.

The Minds That Rise And Become Really Great Are Never Self-satisfied, But Still Continue To Strive.

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.
