When Entering On New Ground We Must Not Be Afraid To Express Even Risky Ideas So As To Stimulate Research In All Directions. As Priestley Put It, We Must Not Remain Inactive Through False Modesty Based On Fear Of Being Mistaken.

Well-observed Facts, Though Brought To Light By Passing Theories, Will Never Die; They Are The Material On Which Alone The House Of Science Will At Last Be Built.

The Joy Of Discovery Is Certainly The Liveliest That The Mind Of Man Can Ever Feel.

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.

I Do Not ... Reject The Use Of Statistics In Medicine, But I Condemn Not Trying To Get Beyond Them And Believing In Statistics As The Foundation Of Medical Science. ... Statistics ... Apply Only To Cases In Which The Cause Of The Facts Observed Is Still [uncertain Or] Indeterminate. ... There Will Always Be Some Indeterminism ... In All The Sciences, And More In Medicine Than In Any Other. But Man's Intellectual Conquest Consists In Lessening And Driving Back Indeterminism In Proportion As He Gains Ground For Determinism By The Help Of The Experimental Method.
