with his creator, as far as his narrow sphere of action will permit, in the production of happiness.  And thus the happiness and misery of a future state will be the just reward or punishment of promoting or preventing happiness in this.  So artificially, by this means, is the nature of all human virtue and vice contrived, that their rewards and punishments are woven, as it were, in their very essence; their immediate effects give us a foretaste of their future, and their fruits, in the present life, are the proper samples of what they must unavoidably produce in another.  We have reason given us to distinguish these consequences, and regulate our conduct; and, lest that should neglect its post, conscience also is appointed, as an instinctive kind of monitor, perpetually to remind us both of our interest and our duty.”

“Si sic omnia dixisset!” To this account of the essence of vice and virtue, it is only necessary to add, that the consequences of human actions being sometimes uncertain, and sometimes remote, it is not possible, in many cases, for most men, nor in all cases, for any man, to determine what actions will ultimately produce happiness, and, therefore, it was proper that revelation should lay down a rule to be followed, invariably, in opposition to appearances, and, in every change of circumstances, by which we may be certain to promote the general felicity, and be set free from the dangerous temptation of doing evil that good may come.  Because it may easily happen, and, in effect, will happen, very frequently, that our own private happiness may be promoted by an act injurious to others, when yet no man can be obliged, by nature, to prefer, ultimately, the happiness of others to his own; therefore, to the instructions of infinite wisdom, it was necessary that infinite power should add penal sanctions.  That every man, to whom those instructions shall be imparted, may know, that he can never, ultimately, injure himself by benefiting others, or, ultimately, by injuring others benefit himself; but that, however the lot of the good and bad may be huddled together in the seeming confusion of our present state, the time shall undoubtedly come, when the most virtuous will be most happy.

I am sorry, that the remaining part of this letter is not equal to the first.  The author has, indeed, engaged in a disquisition, in which we need not wonder if he fails, in the solution of questions on which philosophers have employed their abilities from the earliest times,

  “And found no end, in wand’ring mazes lost.”

He denies, that man was created perfect, because the system requires subordination, and because the power of losing his perfection, of “rendering himself wicked and miserable, is the highest imperfection imaginable.”  Besides, the regular gradations of the scale of being required, somewhere, “such a creature as man, with all his infirmities about him; and the total removal of those would be altering his nature, and, when he became perfect, he must cease to be man.”
