The Greeks bequeathed to us one of the most beautiful words in our language--the word 'enthusiasm'--en theos--a god within. The grandeur of human actions is measured by the inspiration from which they spring. Happy is he who bears a god within, and who obeys it.

Let me tell you the secret that has led me to my goal. My strength lies solely in my tenacity.

Little science takes you away from God but more of it takes you to Him.

Are the atoms of the dextroacid (tartaric) grouped in the spirals of a right-hand helix or situated at the angles of an irregular tetrahedron, or arranged in such or such particular unsymmetrical fashion? We are unable to reply to these questions. But there can be no reason for doubting that the grouping of the atoms has an unsymmetrical arrangement with a non-superimposable image. It is not less certain that the atoms of the laevo-acid realize precisely an unsymmetrical arrangement of the inverse of the above.

How do you know that the incessant progress of science will not compel scientists to consider that life has existed during eternity, and not matter?

Where observation is concerned, chance favors only the prepared mind.

These are the living springs of great thoughts and great actions. Everything grows clear in the reflections from the Infinite.
