Science brings men nearer to God.

The artificial products do not have any molecular dissymmetry; and I could not indicate the existence of a more profound separation between the products born under the influence of life and all the others.

The more I know, the more nearly is my faith that of the Breton peasant. Could I but know all I would have the faith of a Breton peasant woman.

In the fields of observation chance favors only those minds which are prepared.

I give them experiments and they respond with speeches.

Change only favours minds that are diligently looking and preparing for discovery.
