Art Is 'i'; Science Is 'we'.

A Man Of Science Rises Ever, In Seeking Truth; And If He Never Finds It In Its Wholeness, He Discovers Nevertheless Very Significant Fragments; And These Fragments Of Universal Truth Are Precisely What Constitutes Science.

[those] Who Have An Excessive Faith In Their Theories Or In Their Ideas Are Not Only Poorly Disposed To Make Discoveries, But They Also Make Very Poor Observations.

It Is What We Know Already That Often Prevents Us From Learning.

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

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.
