These are the dangers that threaten the morality of the character when too intimate an association is attempted between sensuous instincts and moral instincts, which can never perfectly agree in real life, but only in the ideal. I admit that the sensuous risks nothing in this association, because it possesses nothing except what it must give up directly duty speaks and reason demands the sacrifice. But reason, as the arbiter of the moral law, will run the more risk from this union if it _receives as a gift_ from inclination what it might _enforce_; for, under the appearance of freedom, the feeling of _obligation_ may be easily lost, and what reason accepts as a favor may quite well be refused it when the sensuous finds it painful to grant it. It is, therefore, infinitely safer for the morality of the character to suspend, at least for a time, this misrepresentation of the moral sense by the sense of the beautiful. It is best of all that reason should command by itself without _mediation_, and that it should show to the will its true master. The remark is, therefore, quite justified, that true morality only knows itself in the school of adversity, and that a continual prosperity becomes easily a rock of offence to virtue. I mean here by prosperity the state of a man who, to enjoy the goods of life, need not commit injustice, and who to conform to justice need not renounce any of the goods of life. The man who enjoys a continual prosperity never sees moral duty face to face, because his inclinations, naturally regular and moderate, always _anticipate_ the mandate of reason, and because no temptation to violate the law recalls to his mind the idea of law. Entirely guided by the sense of the beautiful, which represents reason in the world of sense, he will reach the tomb without having known by experience the dignity of his destiny. On the other hand, the unfortunate man, if he be at the same time a virtuous man, enjoys the sublime privilege of being in _immediate_ intercourse with the divine majesty of the moral law; and as his virtue is not seconded by any inclination, he bears witness in this lower world, and as a human being, of the freedom of pure spirits!
