I have thus briefly sketched the various important inquiries, which the philosophy of mind, in its most extensive sense, may be said to comprehend. The nature of our spiritual being, as displayed in all the phenomena of feeling and thought--the ties which bind us to our fellow-men, and to our Creator--and the prospect of that unfading existence, of which life is but the first dawning gleam; such are the great objects to which in the department of your studies committed to my charge, it will be my office to guide your attention and curiosity. The short period of the few months to which my course is necessarily limited, will not, indeed, allow me to prosecute, with such full investigation as I should wish, every subject that may present itself in so various a range of inquiry. But even these few months, I flatter myself, will be sufficient to introduce you to all which is most important for you to know in the science, and to give such lights as may enable you, in other hours, to explore, with success, the prospects that here, perhaps, may only have opened on your view. It is not, I trust, with the labours of a single season that such inquiries, on your part, are to terminate. Amid the varied occupations and varied pleasures of your future years,--in the privacy of domestic enjoyment, as much as in the busier scenes of active exertion,--the studies on which you are about to enter must often rise to you again with something more than mere remembrance; because there is nothing that can give you interest, in any period or situation of your life, to which they are not related. The science of mind, is the science of yourselves; of all who surround you; of every thing which you enjoy or suffer, or hope or fear: so truly the science of your very being, that it will be impossible for you to look back on the feelings of a single hour, without constantly retracing phenomena that have been here, to a certain extent, the subjects of your analysis and arrangement. The thoughts and faculties of your own intellectual frame, and all which you admire as wonderful in the genius of others,--the moral obligation, which, as obeyed or violated, is ever felt by you with delight or with remorse,--the virtues, of which you think as often as you think of those whom you love; and the vices, which you view with abhorrence, or with pity,--the traces of divine goodness, which never can be absent from your view, because there is no object in nature which does not exhibit them,--the feeling of your dependence on the gracious Power that formed you,--and the anticipation of a state of existence more lasting than that which is measured by the few beatings of a feeble pulse,--these in their perpetual recurrence, must often recal to you the inquiries that, in this place, engaged your early attention. It will be almost as little possible for you to abandon wholly such speculations, as to look on the familiar faces of your home with a
