The Joy Of Discovery Is

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.

Il Ne Fallait Jamais Faire Des Expériences Pour Confirmer Ses Idées, Mais Simplement Pour Les Contrôler. We Must Never Make Experiments To Confirm Our Ideas, But Simply To Control Them.

Our Ideas Are Only Intellectual Instruments Which We Use To Break Into Phenomena; We Must Change Them When They Have Served Their Purpose, As We Change A Blunt Lancet That We Have Used Long Enough.

Men Who Have Excessive Faith In Their Theories Or Ideas Are Not Only Ill Prepared For Making Discoveries; They Also Make Very Poor Observations. Of Necessity, They Observe With A Preconceived Idea, And When They Devise An Experiment, They Can See, In Its Results,only A Confirmation Of Their Theory. In This Way They Distort Observation And Often Neglect Very Important Facts Because They Do Not Further Their Aim.

Science Rejects The Indeterminate.
