"Have the philosophers, who presided over your highness's education, ever entertain'd you on the nature of the soul?" "Oh! very often," said Mangogul; "but all their systems had no other end, but giving me uncertain notions of it; and were it not for an inward sentiment, which seems to suggest to me, that it is a substance different from matter, I should either have denied its existence, or confounded it with the body. Would you undertake to clear up this chaos?" "So far from it," replied Mirzoza, "that I am not farther advanced on that head than your pedagogues. The only difference between them and me, is that I suppose the existence of a substance different from matter, and that they hold it demonstrated. But this substance, if it exists, must be lodged somewhere. Have they not preached many extravagances to you on that article?" "No," said Mangogul: "they all pretty generally agreed, that it resides in the head; and this opinion to me seemed probable. 'Tis the head that thinks, imagines, reflects, judges, disposes, commands; and we say every day of a man who does not think, that he has no brains, or that he wants a head." "Well then," replied the Sultana, "the result of your long studies and of all your philosophy, is, to suppose a fact, and to ground it on popular expressions. Prince, what would you say of your first geographer, if he presented your highness with a map of your dominions, in which he had put the east in the west, and the north in the south?" "That is too gross an error," answered Mangogul, "for any geographer to have ever committed." "That may be," continued the favorite; "and in the case before us, your philosophers are greater bunglers, than the most bungling geographer can be. They had not a vast empire to survey; the business was not to fix the limits of the four parts of the world: all they had to do, was to enter into themselves, and there mark the true seat of their soul. Yet they have placed the east in the west, and the south in the north. They have pronounced that the soul is in the head, whereas the greatest part of mankind dye, without it's ever inhabiting that appartment; and its first residence is in the feet." "In the feet!" interrupted the Sultan. "That is the most empty notion that I have ever heard." "Yes, in the feet," replied Mirzoza, "and this opinion, which to you seems so silly, will, upon thoroughly examining it, become rational; contrary to all those, which you allow as true, and which upon a thorough examination are found to be false. Your highness agreed with me just now, that the existence of our soul was founded on the interior testimony alone, which it bore to itself; and I will now demonstrate, that all the proofs imaginable of sense concur to fix the soul in the seat which I have assigned it." "There we expect you," said Mangogul.
