on the principles of government, comprised in about three hundred pages octavo.  He has lately published a third work on Political Economy, comprising the whole subject within about the same compass; in which all its principles are demonstrated with the severity of Euclid, and, like him, without ever using a superfluous word.  I have procured this to be translated, and have been four years endeavoring to get it printed:  but, as yet, without success.  In the mean time, the author has published the original in France, which he thought unsafe while Bonaparte was in power.  No printed copy, I believe, has yet reached this country.  He has his fourth and last work now in the press at Paris, closing, as he conceives, the circle of metaphysical sciences.  This work, which is on Ethics, I have not seen, but suspect I shall differ from it in its foundation, although not in its deductions.  I gather from his other works that he adopts the principle of Hobbes, that justice is founded in contract solely, and does not result from the constitution of man.  I believe, on the contrary, that it is instinct and innate, that the moral sense is as much a part of our constitution as that of feeling, seeing, or hearing; as a wise creator must have seen to be necessary in an animal destined to live in society:  that every human mind feels pleasure in doing good to another:  that the non-existence of justice is not to be inferred from the fact that the same act is deemed virtuous and right in one society which is held vicious and wrong in another; because, as the circumstances and opinions of different societies vary, so the acts which may do them right or wrong must vary also; for virtue does not consist in the act we do, but in the end it is to effect.  If it is to effect the happiness of him to whom it is directed, it is virtuous, while, in a society under different circumstances and opinions, the same act might produce pain, and would be vicious.  The essence of virtue is in doing good to others, while what is good may be one thing in one society, and its contrary in another.  Yet, however we may differ as to the foundation of morals (and as many foundations have been assumed as there are writers on the subject nearly), so correct a thinker as Tracy will give us a sound system of morals.  And, indeed, it is remarkable, that so many writers, setting out from so many different premises, yet meet all in the same conclusions.  This looks as if they were guided unconsciously, by the unerring-hand of instinct.
