Science Rejects The Indeterminate.

We Must Keep Our Freedom Of Mind, ... And Must Believe That In Nature What Is Absurd, According To Our Theories, Is Not Always Impossible.

Experiment Is Fundamentally Only Induced Observation.

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.

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.

Men Who Believe Too Firmly In Their Theories, Do Not Believe Enough In The Theories Of Others. So ... These Despisers Of Their Fellows ... Make Experiments Only To Destroy A Theory, Instead Of To Seek The Truth.
