He who sees without loving is only straining his eyes in the darkness.

Our reason may prove what it will: our reason is only a feeble ray that has issued from Nature.

It is only in the space that our thoughts and our feelings enclose that our happiness can breathe in freedom.

Physical suffering apart, not a single sorrow exists that can touch us except through our thoughts.

Remember that happiness is as contagious as gloom. It should be the first duty of those who are happy to let others know of their gladness.

To have known how to change the past into a few saddened smiles-is this not to master the future?

They think that nothing will happen because they have closed their doors, and they do not know that it is in the soul that things always happen, and that the world does not end at their housedoor.
