Oration on Lafayette (1834)
Context: There have doubtless been, in all ages, men, whose discoveries or inventions, in the world of matter or of mind, have opened new avenues to the dominion of man over the material creation; have increased his means or his faculties of enjoyment; have raised him in nearer approximation to that higher and happier condition, the object of his hopes and aspirations in his present state of existence.
Lafayette discovered no new principle of politics or of morals. He invented nothing in science. He disclosed no new phenomenon in the laws of nature. Born and educated in the highest order of feudal Nobility, under the most absolute Monarchy of Europe, in possession of an affluent fortune, and master of himself and of all his capabilities at the moment of attaining manhood, the principle of republican justice and of social equality took possession of his heart and mind, as if by inspiration from above. He devoted himself, his life, his fortune, his hereditary honors, his towering ambition, his splendid hopes, all to the cause of liberty. He came to another hemisphere to defend her. He became one of the most effective champions of our Independence; but, that once achieved, he returned to his own country, and thenceforward took no part in the controversies which have divided us. In the events of our Revolution, and in the forms of policy which we have adopted for the establishment and perpetuation of our freedom, Lafayette found the most perfect form of government. He wished to add nothing to it.

Human nature is evil

Die Nachfrage des Ökonomen ist nicht die wirkliche Nachfrage, seine Konsumtion ist eine künstliche. Dem Ökonomen ist nur der ein wirklich Fragender, ein wirklicher Konsument, der für das, was er empfängt, ein Äquivalent zu bieten hat.
