Science Does Not Permit Exceptions.

Feeling Alone Guides The Mind.

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

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.

We Achieve More Than We Know. We Know More Than We Understand. We Understand More Than We Can Explain.

The Great Experimental Principle, Then, Is Doubt, That Philosophic Doubt Which Leaves To The Mind Its Freedom And Initiative, And From Which The Virtues Most Valuable To Investigators In Physiology And Medicine Are Derived.
