The whole of society rests upon industry. Industry is the sole guarantee of its existence, the single source of all its wealth and all its prosperity… - Claude Henri de Rouvroy, comte de Saint-Simon

The philosophy of the last century was revolutionary ; that of the nineteenth century must be constructive. Lack of institutions leads to the destruction of all society; outworn institutions prolong the ignorance and the prejudices of the times which produce them. Shall we be forced to choose between barbarism and stupidity? Writers of the nineteenth century, you alone can avert this frightful dilemma.

Politics is the science of production.

The philosopher places himself at the summit of thought; from there he views what the world has been and what it must become. He is not just an observer, he is an actor; he is an actor of the highest kind in a moral world because it is his opinion of what the world must become that regulates society.
