Facts do not find their way into the world in which our beliefs reside; they did not produce our beliefs, they do not destroy them; they may inflict on them the most constant refutations without weakening them, and an avalanche of afflictions or ailments succeeding one another without interruption in a family will not make it doubt the goodness of its God or the talent of its doctor.

We passionately long that there may be another life in which we shall be similar to what we are here below. But we do not pause to reflect that, even without waiting for that other life, in this life, after a few years we are unfaithful to what we have been, to what we wished to remain immortally.
