Such was the penalty which the great man paid for scorning all new knowledge as _idéalogie_. The principles set forth by Quesnay, Turgot, and Adam Smith were to him mere sophistical juggling. He once said to Mollien: "I seek the good that is practical, not the ideal best: the world is very old: we must profit by its experience: it teaches that old practices are worth more than new theories: you are not the only one who knows trade secrets."[230] This was his general attitude towards the exponents of new financial or commercial views. Indeed, we can hardly think of this great champion of external control and state intervention favouring the open-handed methods of _laisser faire_. Unhappy France, that gave this motto to the world but let her greatest ruler emphasize her recent reaction towards commercial mediævalism! Luckless Emperor, who aspired to found the United States of Europe, but outraged the principle which most surely and lastingly works for international harmony, that of Free Trade! While the Trianon tariff sought to hinder the import of England's colonial products, or, failing that, to reap a golden harvest from them, Napoleon further endeavoured to terrify continental dealers from accepting any of her manufactures. His Fontainebleau decree of October 18th, 1810, ordered that all such goods should be seized and publicly burnt; and five weeks later special tribunals were instituted for enforcing these ukases and for trying all persons, whether smugglers caught red-handed or shopkeepers who inadvertently offered for sale the cottons of Lancashire or the silks of Bengal.
