Ah! why have you deceived me?--Has a six months' absence obliterated from your remembrance the precept I so earnestly and incessantly laboured to inculcate--the value and importance of unequivocal sincerity? A precept, which I now take shame to myself for not having more implicitly observed! Had I supposed your affection for Joanna more than a boyish partiality; had I not believed that a few months' absence would entirely erase it from your remembrance; had I not been assured that her heart was devoted to another object, a circumstance of which she had herself frankly informed you; I should not now have distrusted your fortitude, when obliged to wound your feelings with the intelligence--that the woman, whom you have so wildly persecuted, was, yesterday, united to another. TO THE SAME I resume my pen. Your letter, which Joanna a few days since put into my hands, has cost me--Ah! my Augustus, my friend, my son--what has it not cost me, and what impressions has it not renewed? I perceive the vigour of your mind with terror and exultation. But you are mistaken! Were it not for the insuperable barrier that separates you, for ever, from your hopes, perseverance itself, however active, however incessant, may fail in attaining its object. Your ardent reasoning, my interesting and philosophic young friend, though not unconsequential, is a finely proportioned structure, resting on an airy foundation. The science of morals is not incapable of demonstration, but we want a more extensive knowledge of particular facts, on which, in any given circumstance, firmly to establish our data.--Yet, be not discouraged; exercise your understanding, think freely, investigate every opinion, disdain the rust of antiquity, raise systems, invent hypotheses, and, by the absurdities they involve, seize on the clue of truth. Rouse the nobler energies of your mind; be not the slave of your passions, neither dream of eradicating them. Sensation generates interest, interest passion, passion forces attention, attention supplies the powers, and affords the means of attaining its end: in proportion to the degree of interest, will be that of attention and power. Thus are talents produced. Every man is born with sensation, with the aptitude of receiving impressions; the force of those impressions depends on a thousand circumstances, over which he has little power; these circumstances form the mind, and determine the future character. We are all the creatures of education; but in that education, what we call chance, or accident, has so great a share, that the wisest preceptor, after all his cares, has reason to tremble: one strong affection, one ardent incitement, will turn, in an instant, the whole current of our thoughts, and introduce a new train of ideas and associations.
