I will not make use of any of those subtle arguments you have taught me to despise; and which, though they fill so many volumes, never yet made one man virtuous. Peace to those gloomy reasoners! to what ravishing delights their hearts are strangers! leave, my friend, those idle moralists, and consult your own breast. It is there you will always find a spark of that sacred fire, which hath so often inflamed us with love for the sublimest virtue. It is there you will trace the lasting image of true beauty, the contemplation of which inspires us with a sacred enthusiasm; an image which the passions may continually defile, but never can efface. [19] Remember those tears of pleasure, those palpitations of heart, those transports which raised us above ourselves at the recital of heroic examples, which have done honour to human nature. Would you know which is most truly desirable, riches or virtue? reflect on that which the heart prefers in its unprejudiced moments: think on that which interests us most in the perusal of history. Did you never covet the riches of Croesus, the honours of Caesar, nor the pleasures of Heliogabalus? If they were happy, why did you not wish to be placed in the same situation? But they were not, you were sensible they were not, happy; you were sensible they were vile and contemptible; and that bad men, however fortunate, are not objects of envy.
What characters did you then contemplate with the greatest pleasure? what examples did you most admire? which did you desire most to imitate? inexpressible are the charms of ever-blooming virtue: it was the condemn’d Athenian, drinking hemlock; it was Brutus, dying for his country: it was Regulus, in the midst of tortures: it was Cato, plunging his dagger in his breast. These were the unfortunate heroes, whose virtues excited your envy, while your own sensations bore witness of that real felicity they enjoyed, under their apparent misfortunes. Think not this sentiment peculiar to yourself; it is the sentiment of all mankind, and that frequently in spite of themselves. That divine image of virtue, imprinted universally on the mind, displays irresistible charms even to the least virtuous. No sooner doth passion permit us to contemplate its beauty, but we wish to resemble it; and, if the most wicked of mankind could but change his being, he would chuse to be virtuous.
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 knowing how to conduct them to lasting felicity. What helps it, then, to obtain one advantage at the expense of another? to gain _without_ what we lose from _within_; to procure the means of happiness, and lose the art of employing them. Is it not better also, if we can but enjoy one of these advantages, to sacrifice what the power of fortune may restore, to that which once lost can never be recovered? none should know better than I, who have imbittered all the sweets of my life, by thinking to increase them. Let the vicious and profligate then, who display their good fortune but keep their hearts a secret, let them advance what they will; be assured that if there be one instance of happiness upon earth it must be found in the breast of the virtuous. Heaven hath bestowed on you an happy inclination for what is virtuous and good: listen then only to your own desires, follow only your own inclinations, and think above all on the growth of our infant affections. So long as the remembrance of those delightful moments of innocence shall remain, it will be impossible that you should cease to love that which rendered them so endearing; it will be impossible the charms of moral excellence should ever be effaced from your mind, or that you should wish to obtain Eloisa by means unworthy of yourself. Can anyone enjoy a pleasure for which he has lost the taste? no, to be able to possess that which one loves, it is necessary the heart that loved it should be still the same.
I come now to my second point: you see I have not forgot my logic; it is possible, my friend, without love to have the sublime sentiments of a great mind; but a love like ours supplies its flame, which being once extinguished, the soul becomes languid; and a heart once exhausted is good for nothing. Tell me, what should we be if we ceased to love? is it not better to lose our existence than our sensibility? or could you resolve to endure the life of an ordinary being, after having tasted every delight that can ravish the heart of man? you are going to visit populous cities, where your age and figure, rather than your merit, will lay a thousand snares for your fidelity. Insinuating coquetry will affect the language of tenderness, and please without deceiving you. You will not seek love, but enjoyment; you will taste it without love, and not know it for the same pleasure. I know not whether you will find in another the heart of Eloisa; but of this I am certain, you will never experience with another those ecstasies you have tasted with her. The vacancy of your exhausted mind will forebode the destiny I predict. Sadness and care will overwhelm you in the midst of frivolous amusements. The remembrance of our first transports will pursue you in spite of yourself; my image, an hundred times more beautiful than I ever was, will overtake you. In a moment the veil of disgust will be thrown over all your delights, and a thousand bitter reflections rush into your mind. My best beloved, my amiable friend, Oh, should you ever forget me----Alas! I can but die; but you, you, shall live base and unhappy, and my death will be but too severely revenged.
Forget not then that Eloisa, who lived for you, and whose heart can never be another’s. I can say nothing more regarding that dependence in which Providence hath placed me: but, after having recommended fidelity to you, it is but just to give you the only pledge of mine that is in my power. I have consulted, not my duty, my distracted mind knows that no longer, but I have examined my heart, the last guide of those who can follow no other; and behold the result of its examination: I am determined never to be your wife without the consent of my father, but I will never marry another without your consent; of this I give you my word, which, whatever happens, I will keep sacred, nor is there a power on earth can make me break my promise. Be not, therefore, disquieted at what may befall me in your absence. Go, my dear friend, pursue, under the auspices of the most tender love, a destiny worthy to crown your merit: mine is in your hands, as much as it is in my power to commit it, and never shall it be altered but with your consent.
