sensations, recall each other mechanically. On this principle, as a ground work, he built up the whole system of human language, as one continued process of association. He showed in what sense not only general terms, but generic images, — under the name of abstract ideas, — actually existed, and in what consist their nature and power. As one word may become the general exponent of many, so by association a simple image may represent a whole class. But in truth Hobbes himself makes no claims to any discovery, and introduces this law of association, or (in his own language) discursion of mind, as an admitted fact, in the solution alone of which, and this by causes purely physiological, he arrogates any originality. His system is briefly this; whenever the senses are impinged on by external objects, whether by the rays of light reflected from them, or by effluxes of their finer particles, there results a correspondent motion of the innermost and subtlest organs. This motion constitutes a representation, and there remains an impression of the same, or a certain disposition to repeat the same motion. Whenever we feel several objects at the same time, the impressions that are left, (or in the language of Mr. Hume, the ideas,) are linked together. Whenever therefore any one of the movements, which constitute a complex impression, is renewed through the senses, the others succeed mechanically. It follows of necessity, therefore, that Hobbes, as well as Hartley and all others who derive association from the connection and interdependence of the supposed matter, the movements of which constitute our thoughts, must have reduced all its forms to the one law of Time. But even the merit of announcing this law with philosophic precision cannot be fairly conceded to him. For the objects of any two ideas need not have coexisted in the same sensation in order to become mutually associable. The same result will follow when one only of the two ideas has been represented by the senses, and the other by the memory.

      Long however before either Hobbes or Des Cartes the law of association had been defined, and its important functions set forth by Ludovicus Vives. Phantasia, it is to be noticed, is employed by Vives to express the mental power of comprehension, or the active function of the mind; and imaginatio for the receptivity (via receptiva) of impressions, or for the passive perception. The power of combination he appropriates to the former: “quae singula et simpliciter acceperat imaginatio, ea conjungit et disjungait phantasia.” And the law by which the thoughts are spontaneously presented follows thus: “quae simul sunt a phantasia comprehensa, si alterutrum occurrat, solet secum alterum representare.” To time therefore he subordinates all the other exciting causes of association. The soul proceeds “a causa ad effectum, ab hoc ad instrumentum, a parte ad totum;” thence to the place, from place to person, and from this to whatever preceded or followed, all as being parts of a total impression, each of which may recall the other. The apparent springs “saltus vel transitus etiam longissimos,” he explains by the same thought having been a component part of two or more total impressions. Thus “ex Scipione venio in cogitationem potentiae Turcicae, propter victorias ejus de Asia, in qua regnabat Antiochus.”

      But from Vives I pass at once to the source of his doctrines, and (as far as we can judge from the remains yet extant of Greek philosophy) as to the first, so to the fullest and most perfect enunciation of the associative principle, namely, to the writings of Aristotle; and of these in particular to the treatises De Anima, and “De Memoria,” which last belongs to the series of essays entitled in the old translations Parva Naturalia. In as much as later writers have either deviated from, or added to his doctrines, they appear to me to have introduced either error or groundless supposition.

      In the first place it is to be observed, that Aristotle’s positions on this subject are unmixed with fiction. The wise Stagyrite speaks of no successive particles propagating motion like billiard balls, as Hobbes; nor of nervous or animal spirits, where inanimate and irrational solids are thawed down, and distilled, or filtrated by ascension, into living and intelligent fluids, that etch and re-etch engravings on the brain, as the followers of Des Cartes, and the humoral pathologists in general; nor of an oscillating ether which was to effect the same service for the nerves of the brain considered as solid fibres, as the animal spirits perform for them under the notion of hollow tubes, as Hartley teaches — nor finally, (with yet more recent dreamers) of chemical compositions by elective affinity, or of an electric light at once the immediate object and the ultimate organ of inward vision, which rises to the brain like an Aurora Borealis, and there, disporting in various shapes, — as the balance of plus and minus, or negative and positive, is destroyed or reestablished, — images out both past and present. Aristotle delivers a just theory without pretending to an hypothesis; or in other words a comprehensive survey of the different facts, and of their relations to each other without supposition, that is, a fact placed under a number of facts, as their common support and explanation; though in the majority of instances these hypotheses or suppositions better deserve the name of upopoiaeseis, or suffictions. He uses indeed the word kinaeseis, to express what we call representations or ideas, but he carefully distinguishes them from material motion, designating the latter always by annexing the words en topo, or kata topon. On the contrary, in his treatise De Anima, he excludes place and motion from all the operations of thought, whether representations or volitions, as attributes utterly and absurdly heterogeneous.

      The general law of association, or, more accurately, the common condition under which all exciting causes act, and in which they may be generalized, according to Aristotle is this. Ideas by having been together acquire a power of recalling each other; or every partial representation awakes the total representation of which it had been a part. In the practical determination of this common principle to particular recollections, he admits five agents or occasioning causes: first, connection in time, whether simultaneous, preceding, or successive; second, vicinity or connection in space; third, interdependence or necessary connection, as cause and effect; fourth, likeness; and fifth, contrast. As an additional solution of the occasional seeming chasms in the continuity of reproduction he proves, that movements or ideas possessing one or the other of these five characters had passed through the mind as intermediate links, sufficiently clear to recall other parts of the same total impressions with which they had coexisted, though not vivid enough to excite that degree of attention which is requisite for distinct recollection, or as we may aptly express it, after consciousness. In association then consists the whole mechanism of the reproduction of impressions, in the Aristotelian Psychology. It is the universal law of the passive fancy and mechanical memory; that which supplies to all other faculties their objects, to all thought the elements of its materials.

      In consulting the excellent commentary of St. Thomas Aquinas on the Parva Naturalia of Aristotle, I was struck at once with its close resemblance to Hume’s Essay on Association. The main thoughts were the same in both, the order of the thoughts was the same, and even the illustrations differed only by Hume’s occasional substitution of more modern examples. I mentioned the circumstance to several of my literary acquaintances, who admitted the closeness of the resemblance, and that it seemed too great to be explained by mere coincidence; but they thought it improbable that Hume should have held the pages of the Angelic Doctor worth turning over. But some time after Mr. Payne showed Sir James Mackintosh some odd volumes of St. Thomas Aquinas, partly perhaps from having heard that he had in his Lectures passed a high encomium on this canonized philosopher; but chiefly from the fact, that the volumes had belonged to Mr. Hume, and had here and there marginal marks and notes of reference in his own hand writing. Among these volumes was that which contains the Parva Naturalia, in the old Latin version, swathed and swaddled in the commentary afore mentioned

      It remains then for me, first to state wherein Hartley differs from Aristotle; then, to exhibit the grounds of my conviction, that he differed only to err: and next as the result, to show, by what influences of the choice and judgment the associative power becomes either memory or fancy; and, in conclusion, to appropriate the remaining offices of the mind to the reason, and the imagination. With my best efforts to be as perspicuous as the nature of language will permit on such a subject, I earnestly solicit the good wishes and friendly patience of my readers, while I thus go “sounding on my dim and perilous way.”

      That Hartley’s system, as far as it differs from that of Aristotle, is neither tenable in theory, nor founded in facts.
