“There are some very curious phenomena connected with the origin and growth of these dispositions,” replied the surgeon. “In the first place, all dispositions are formed in the individual by the pressure of external circumstances, no matter how or from whence directed: evil dispositions and good, and they arise at different times and sometimes in succession. When created, they set with a certain impetus in a certain direction; and as in these the extremes meet, if another impetus is given, they will proceed from bad to good to the same distance they advanced from good to bad. This is the cause of individuals having been notorious for vice becoming eminent for virtue. Water flowing from the top of a mountain is capable by its own power of finding its level on a mountain of a similar elevation; and the impetus of vice being carried down a certain way ascends by the impetus of good a like height. This accounts for the old proverb, ‘The greater the sinner the greater the saint;’ that is to say, the force in one produces a like force in the other. Again, the disposition to love has frequently been followed by the disposition to hate, as nearly as possible to the same extent; and the disposition to happiness may as frequently be succeeded by the disposition to misery.”

“But supposing the impetus to be carried down, it will want the application of no other power to carry it up; and if carried up, will unassisted carry itself down,” remarked the professor.

“Not so,” replied the doctor: “Evil is of a heavy nature; and when it descends, clings to the soil at the bottom, unless it receive another impetus: and good is of a light nature, that naturally rises, and when it has attained its highest elevation would there remain, were it not sent down with a similar force.”

“The idea is ingenious, certainly,” said the young merchant.

“And that is all the merit it possesses,” observed Fortyfolios, whose more orthodox notions could not tolerate such an hypothesis. “Were such a theory generally adopted, its mischief would be incalculable. It would loosen our sense of the moral obligations, and utterly destroy all the established ideas of right and wrong.”

“As for the moral obligations, don’t you see,” replied Tourniquet, “I am perfectly convinced that it would place them on a much more secure footing than they now possess; and if established notions on the subject are erroneous, which I can prove them to be, the sooner they are knocked on the head the better. I have already shown to you, in the instance of the natural child, that the idea of virtue in the community is very vague, unsettled, and unphilosophical, and creates more mischief than it does good; and if we take the ideas of the same principle existing at different times and in different communities, we shall find even this confusion worse confounded. Things the most opposite to the true character of virtue have been considered worthy of general adoption as virtues. Thieving has existed as a virtue; drunkenness has existed as a virtue; profligacy has existed as a virtue; murder has existed as a virtue; and many others of the most abominable vices have, at various intervals, with various people, been practised, avowed, and defended, as if they were the most admirable of virtues. It is not many centuries since the natives, on the coast of Guinea, and the inhabitants of other countries, were taught to steal, and the cleverest thief was an object of as much admiration among them as the most virtuous member of the community; but there is no necessity to go to a state of barbarism for an illustration of the honour with which dishonesty has been regarded; for in all speculations, in all trading dealings, in all gambling transactions, and in all appropriations of property acquired by one party from another by a certain cunning or skill, of which the other is not possessed, there is nothing else but stealing; and yet a person acquiring property by such means is generally thought to be respectable, and respectability is considered a virtue.”

“I am afraid, if your argument be true, that there is but little real honesty in the world,” remarked Oriel.

“It is as I have stated,” replied the doctor. “I have read of states in which the man who could swallow some half a dozen bottles of wine, and make his friends follow his example—in other words, a man who practised habitual intoxication—had the reputation of being ‘a good fellow,’ when amongst the same people goodness was considered virtue; but even at the present day, in some parts of the world, intemperance is regarded as a thing to be applauded rather than censured, although it is not only a vice, but being the most direct channel to all other vices ought to be held in detestation as the most vicious of evil inclinations.”

Oriel Porphyry thought of the scene he had witnessed at Canton; but he smiled, and said nothing.
