Science Admits No Exceptions; Otherwise There Would

The Constancy Of The Internal Environment Is The Condition For Free And Independent Life: The Mechanism That Makes It Possible Is That Which Assured The Maintenance, With The Internal Environment, Of All The Conditions Necessary For The Life Of The Elements.

All The Vital Mechanisms, Varied As They Are, Have Only One Object, That Of Preserving Constant The Conditions Of Life In The Internal Environment.

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.

In A Word, I Consider Hospitals Only As The Entrance To Scientific Medicine; They Are The First Field Of Observation Which A Physician Enters; But The True Sanctuary Of Medical Science Is A Laboratory; Only There Can He Seek Explanations Of Life In The Normal And Pathological States By Means Of Experimental Analysis.

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