Feeling Alone Guides The Mind.

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.

Man Can Learn Nothing Unless He Proceeds From The Known To The Unknown.

In The Patient Who Succumbed, The Cause Of Death Was Evidently Something Which Was Not Found In The Patient Who Recovered; This Something We Must Determine, And Then We Can Act On The Phenomena Or Recognize And Foresee Them Accurately. But Not By Statistics Shall We Succeed In This; Never Have Statistics Taught Anything, And Never Can They Teach Anything About The Nature Of The Phenomenon.

First Causes Are Outside The Realm Of Science.
