Mediocre Men Often Have The Most Acquired Knowledge. It Is In The Darker. It Is In The Darker Regions Of Science That Great Men Are Recognized; They Are Marked By Ideas Which Light Up Phenomena Hitherto Obscure And Carry Science Forward.

The Fact That Knowledge Endlessly Recedes As The Investigator Is About To Grasp It Is What Constitutes At The Same Time His Torment And Happiness.

The Terrain Is Everything; The Germ Is Nothing.
