Excuse this rhapsody, my dear friend, you know it is originally derived from you, and it is due to the passion that inspired it. I do not take upon me to instruct you, by repeating your own maxims, but endeavour to enforce their application to yourself. Now is the time to put in practice your own precepts, and to shew how well you can act what you so well know to teach. Though it is not expected you should be put to the trials of a Cato, or a Regulus, yet every man ought to cherish a love for his country, resolution and integrity, and to keep his promise inviolable, even at the expense of his life. Private virtues are often the more sublime as they less aspire to public approbation, but have their end in the testimony of a good conscience, which gives the virtuous a more solid satisfaction, than the loudest applauses of the multitude. Hence you may see true greatness is confirmed to no one station of life, and that no man can be happy who is not the object of his own esteem; for, if the height of self- enjoyment consists in the contemplation of the truly beautiful, how can the vicious man admire the beauty of virtue in others, and not be forced to despise himself. I am not apprehensive of your being corrupted by sensual pleasures; a heart so refined as yours will be in little danger from the gross seductions of appetite. But there are others more dangerous and sentimental. I dread the effects of the maxims and lessons of the world; I dread the force of vicious examples, so constantly present, and so generally extensive: I dread those subtle sophisms by which vice is excused and defended: I dread, in short, lest your heart should impose upon itself, and render you less difficult about the means of acquiring importance than you would be, if our union were not to be the consequence. I only caution you, my friend, against the danger; your own discretion must do the rest: a foresight of accidental evils, however, is no small step towards their prevention. I will add but one reflection more, which, in my opinion, disproves the false arguments of vice, exposes the mistaken conceits of folly, and ought alone to direct a wise man to pursue his sovereign good. This is, that the source of true happiness is not confined to the desired object, nor to the heart which possesses it, but consists in a certain relation between the one and the other: that every object of our desires will not produce the happiness sought in its possession, nor is the heart at all times in a disposition to receive it. If the utmost refinement of intellectual pleasure is not sufficient alone to constitute our felicity, surely all the voluptuous pleasures on earth cannot make the depraved man happy. There is on both sides a necessary preparative, a certain combination of causes, from which results that delightful sensation so earnestly sought after by every sensible being, and for ever unexperienced by the pretended philosopher, who coldly nips his pleasures in the bud, for want of
