must denominate this intermediate faculty in all its degrees and determinations, the IMAGINATION. But, in common language, and especially on the subject of poetry, we appropriate the name to a superior degree of the faculty, joined to a superior voluntary control over it. Contemporaneity, then, being the common condition of all the laws of association, and a component element in the materia subjecta, the parts of which are to be associated, must needs be co-present with all. Nothing, therefore, can be more easy than to pass off on an incautious mind this constant companion of each, for the essential substance of all. But if we appeal to our own consciousness, we shall find that even time itself, as the cause of a particular act of association, is distinct from contemporaneity, as the condition of all association. Seeing a mackerel, it may happen, that I immediately think of gooseberries, because I at the same time ate mackerel with gooseberries as the sauce. The first syllable of the latter word, being that which had coexisted with the image of the bird so called, I may then think of a goose. In the next moment the image of a swan may arise before me, though I had never seen the two birds together. In the first two instances, I am conscious that their co-existence in time was the circumstance, that enabled me to recollect them; and equally conscious am I that the latter was recalled to me by the joint operation of likeness and contrast. So it is with cause and effect: so too with order. So I am able to distinguish whether it was proximity in time, or continuity in space, that occasioned me to recall B on the mention of A. They cannot be indeed separated from contemporaneity; for that would be to separate them from the mind itself. The act of consciousness is indeed identical with time considered in its essence. I mean time per se, as contra-distinguished from our notion of time; for this is always blended with the idea of space, which, as the opposite of time, is therefore its measure. Nevertheless the accident of seeing two objects at the same moment, and the accident of seeing them in the same place are two distinct or distinguishable causes: and the true practical general law of association is this; that whatever makes certain parts of a total impression more vivid or distinct than the rest, will determine the mind to recall these in preference to others equally linked together by the common condition of contemporaneity, or (what I deem a more appropriate and philosophical term) of continuity. But the will itself by confining and intensifying [25] the attention may arbitrarily give vividness or distinctness to any object whatsoever; and from hence we may deduce the uselessness, if not the absurdity, of certain recent schemes which promise an artificial memory, but which in reality can only produce a confusion and debasement of the fancy. Sound logic, as the habitual subordination of the individual to the species, and of
