Temperament also enters fully into the system of illusions and shuts us in a prison of glass which we cannot see. There is an optical illusion about every person we meet. In truth they are all creatures of given temperament, which will appear in a given character, whose boundaries they will never pass: but we look at them, they seem alive, and we presume there is impulse in them. In the moment it seems impulse; in the year, in the lifetime, it turns out to be a certain uniform tune which the revolving barrel of the music-box must play. Men resist the conclusion in the morning, but adopt it as the evening wears on, that temper prevails over everything of time, place, and condition, and is inconsumable in the flames of religion. Some modifications the moral sentiment avails to impose, but the individual texture holds its dominion, if not to bias the moral judgments, yet to fix the measure of activity and of enjoyment. I thus express the law as it is read from the platform of ordinary life, but must not leave it without noticing the capital exception. For temperament is a power which no man willingly hears any one praise but himself. On the platform of physics we cannot resist the contracting influences of so-called science. Temperament puts all divinity to rout. I know the mental proclivity of physicians. I hear the chuckle of the phrenologists. Theoretic kidnappers and slave-drivers, they esteem each man the victim of another, who winds him round his finger by knowing the law of his being; and by such cheap signboards as the color of his beard or the slope of his occiput, reads the inventory of his fortunes and character. The grossest ignorance does not disgust like this impudent knowingness. The physicians say they are not materialists; but they are:--Spirit is matter reduced to an extreme thinness: O so thin!--But the definition of spiritual should be, that which is its own evidence. What notions do they attach to love! what to religion! One would not willingly pronounce these words in their hearing, and give them the occasion to profane them. I saw a gracious gentleman who adapts his conversation to the form of the head of the man he talks with! I had fancied that the value of life lay in its inscrutable possibilities; in the fact that I never know, in addressing myself to a new individual, what may befall me. I carry the keys of my castle in my hand, ready to throw them at the feet of my lord, whenever and in what disguise soever he shall appear. I know he is in the neighborhood hidden among vagabonds. Shall I preclude my future by taking a high seat and kindly adapting my conversation to the shape of heads? When I come to that, the doctors shall buy me for a cent.--'But, sir, medical history; the report to the Institute; the proven facts!'--I distrust the facts and the inferences. Temperament is the veto or limitation-power in the constitution, very justly applied to restrain an opposite excess in the
