La lecture de tous les bons livres est comme une conversation avec les plus honnêtes gens des siècles passés.

The reading of all good books is like conversation with the finest men of past centuries.

Dubium sapientiae initium (Doubt is the origin of wisdom).
The dreams we imagine when we are asleep should not in any way make us doubt the truth of the thoughts we have when we are awake.
