The unfinished is nothing.

Order is man's greatest need, and his true well-being.

Time is but the measure of the difficulty of a conception. Pure thought has scarcely any need of time, since it perceives the two ends of an idea almost at the same moment.

Action and faith enslave thought, both of them in order not be troubled or inconvenienced by reflection, criticism, and doubt.

He who is silent is forgotten; he who does not advance falls back; he who stops is overwhelmed; out distanced, crushed; he who ceases t grow becomes smaller; he who leaves off, gives up; the condition of standing still is the beginning of the end.

Self-interest is an inexhaustible source of convenient illusions. The number of beings who wish to see truly is extraordinarily small.

Latent genius is but a presumption. Everything that can be, is bound to come into being, and what never comes into being is nothing.
