Society rests upon conscience, not upon science.

Common sense is the measure of the possible; it is composed of experience and prevision; it is calculation applied to life.

[T]he habit of scientific analysis ... exhausts the material offered to it...

[I]t is truth alone-scientific, established, proved, and rational truth-which is capable of satisfying nowadays the awakened minds of all classes. We may still say perhaps, 'faith governs the world,'-but the faith of the present is no longer in revelation or in the priest-it is in reason and in science.
