Of memory, which makes so large a part of the excellence of the human soul, and which has so much influence upon all its other powers, but a small portion has been allotted to the animal world. We do not find the grief with which the dams lament the loss of their young, proportionate to the tenderness with which they caress, the assiduity with which they feed, or the vehemence with which they defend them. Their regard for their offspring, when it is before their eyes, is not, in appearance, less than that of a human parent; but when it is taken away, it is very soon forgotten, and, after a short absence, if brought again, wholly disregarded. That they have very little remembrance of any thing once out of the reach of their senses, and scarce any power of comparing the present with the past, and regulating their conclusions from experience, may be gathered from this, that their intellects are produced in their full perfection. The sparrow that was hatched last spring makes her first nest the ensuing season, of the same materials, and with the same art, as in any following year; and the hen conducts and shelters her first brood of chickens with all the prudence that she ever attains. It has been asked by men who love to perplex any thing that is plain to common understandings, how reason differs from instinct; and Prior has with no great propriety made Solomon himself declare, that to distinguish them is _the fool's ignorance, and the pedant's pride_. To give an accurate answer to a question, of which the terms are not completely understood, is impossible; we do not know in what either reason or instinct consists, and therefore cannot tell with exactness how they differ; but surely he that contemplates a ship and a bird's nest, will not be long without finding out, that the idea of the one was impressed at once, and continued through all the progressive descents of the species, without variation or improvement; and that the other is the result of experiments, compared with experiments, has grown, by accumulated observation, from less to greater excellence, and exhibits the collective knowledge of different ages and various professions. Memory is the purveyor of reason, the power which places those images before the mind upon which the judgment is to be exercised, and which treasures up the determinations that are once passed, as the rules of future action, or grounds of subsequent conclusions. It is, indeed, the faculty of remembrance, which may be said to place us in the class of moral agents. If we were to act only in consequence of some immediate impulse, and receive no direction from internal motives of choice, we should be pushed forward by an invincible fatality, without power or reason for the most part to prefer one thing to another, because we could make no comparison but of objects which might both happen to be present.
