Science Rejects The Indeterminate.

Theories Are Like A Stairway; By Climbing, Science Widens Its Horizon More And More, Because Theories Embody And Necessarily Include Proportionately More Facts As They Advance.

In Science, The Best Precept Is To Alter And Exchange Our Ideas As Fast As Science Moves Ahead.

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.

The Physiologist Is Not A Man Of The World, He Is A Scientist, A Man Caught And Absorbed By A Scientific Idea That He Pursues; He No Longer Hears The Cries Of The Animals, No Longer Sees The Flowing Blood, He Sees Only His Idea: Organisms That Hide From Him Problems That He Wants To Discover. He Doesn't Feel That He Is In A Horrible Carnage; Under The Influence Of A Scientific Idea, He Pursues With Delight A Nervous Filament Inside Stinking And Livid Flesh That For Any Other Person Would Be An Object Of Disgust And Horror.

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.
