An irresistible inducement on the present occasion to pursue towards you the course to which I have so long been prompted both by principle and habit, is, that _this_ is certainly the last opportunity I shall ever have of addressing you as pupils. The connexion of teachers and scholars which has subsisted for so many years between yourselves and my family, is about to be dissolved forever. But this circumstance has greatly augmented my solicitude to render the last admonitions I shall ever give you in my character of adviser, of some permanent service to you. They will relate to such endowments of mind and qualities of heart as you will most frequently have occasion to exercise in future life. These are, self-control, gentleness and benevolence of disposition, purity and rectitude of conduct, courtesy and politeness of manner.
The necessity for acquiring self-control arises, not only from the impossibility of gratifying all, even of our lawful wishes--to say nothing of those unhallowed ones which increase in a tenfold proportion from every indulgence--but from the almost continual calls for its exercise in all our intercourse with society. At home or abroad--in the depths of solitude, or in the busiest haunts of men--in all our domestic relations, as well as in those which place us in a more extended sphere of action, this all important quality is in continual demand. In governing ourselves it is indispensable; nor is it much less necessary when duty requires us to govern, direct or persuade others. Even when we are casually brought into the company of strangers, and for a short time only, it often enables us to command respect and to gain esteem, by manifesting the vast superiority of a well regulated mind over one which yields to every impulse of passion that assails it. This inestimable quality of self-control gives additional zest to all our lawful pleasures, and enhances our highest enjoyments, by causing us always to stop short of satiety; while it enables us by God's help, resolutely and undisturbed, to meet all the crosses and trials to which others may subject us. In a word, it arms us against the strongest temptation of our own passions, and empowers us to disregard the worst that can be attempted against us by the passions of other people. It is in fact the _regulator_, (if I may so express myself,) which governs all the machinery of our minds in such a manner as to prevent them from going either too fast or too slow. How many mortifications and disappointments--how much anger, resentment and grief does it not prevent our suffering from the envy, hatred, malice and uncharitableness of the world around us! How often does it save us from the shame and degradation of sensual indulgence; from the turpitude of sin; from the anguish of remorse. It is the effectual check to the depravity of our nature, which a merciful God will enable us always to apply, if we will only ask it of him as we ought--that is, by continual prayer and supplication.
