makes it true or false;
Turns truth to falsehood, falsehood into truth,
By virtue of the Babylonian's tooth.
The inventor of the watch, if this doctrine be true, did not in reality invent it; he only looked on, while the blind causes, the only true artists, were unfolding themselves. So must it have been too with my friend Allston, when he sketched his picture of the dead man revived by the bones of the prophet Elijah. So must it have been with Mr. Southey and Lord Byron, when the one fancied himself composing his Roderick, and the other his Childe Harold. The same must hold good of all systems of philosophy; of all arts, governments, wars by sea and by land; in short, of all things that ever have been or that ever will be produced. For, according to this system, it is not the affections and passions that are at work, in as far as they are sensations or thoughts. We only fancy, that we act from rational resolves, or prudent motives, or from impulses of anger, love, or generosity. In all these cases the real agent is a something-nothing-everything, which does all of which we know, and knows nothing of all that itself does.
The existence of an infinite spirit, of an intelligent and holy will, must, on this system, be mere articulated motions of the air. For as the function of the human understanding is no other than merely to appear to itself to combine and to apply the phaenomena of the association; and as these derive all their reality from the primary sensations; and the sensations again all their reality from the impressions ab extra; a God not visible, audible, or tangible, can exist only in the sounds and letters that form his name and attributes. If in ourselves there be no such faculties as those of the will, and the scientific reason, we must either have an innate idea of them, which would overthrow the whole system; or we can have no idea at all. The process, by which Hume degraded the notion of cause and effect into a blind product of delusion and habit, into the mere sensation of proceeding life (nisus vitalis) associated with the images of the memory; this same process must be repeated to the equal degradation of every fundamental idea in ethics or theology.
Far, very far am I from burthening with the odium of these consequences the moral characters of those who first formed, or have since adopted the system! It is most noticeable of the excellent and pious Hartley, that, in the proofs of the existence and attributes of God, with which his second volume commences, he makes no reference to the principle or results of the first. Nay, he assumes, as his foundations, ideas which, if we embrace the doctrines of his first volume, can exist no where but in the vibrations of the ethereal medium common to the nerves and to the atmosphere. Indeed the whole of the second volume is, with the fewest possible exceptions, independent of his peculiar system. So true is it, that the faith, which saves and sanctifies, is a collective energy, a total act of the whole moral being; that its living sensorium is in the heart; and that no errors of the understanding can be morally arraigned unless they have proceeded from the heart. But whether they be such, no man can be certain in the case of another, scarcely perhaps even in his own. Hence it follows by inevitable consequence, that man may perchance determine what is a heresy; but God only can know who is a heretic. It does not, however, by any means follow that opinions fundamentally false are harmless. A hundred causes may co-exist to form one complex antidote. Yet the sting of the adder remains venomous, though there are many who have taken up the evil thing, and it hurted them not. Some indeed there seem to have been, in an unfortunate neighbour nation at least, who have embraced this system with a full view of all its moral and religious consequences; some—
—–who deem themselves most free,
When they within this gross and visible sphere
Chain down the winged thought, scoffing ascent,
Proud in their meanness; and themselves they cheat
With noisy emptiness of learned phrase,
Their subtle fluids, impacts, essences,
Self-working tools, uncaus'd effects, and all
Those blind omniscients, those almighty slaves,
Untenanting creation of its God!
Such men need discipline, not argument; they must be made better men, before they can become wiser.
The attention will be more profitably employed in attempting to discover and expose the paralogisms, by the magic of which such a faith could find admission into minds framed for a nobler creed. These, it appears to me, may be all reduced to one sophism as their common genus; the mistaking the conditions of a thing for its causes and essence; and the process, by which we arrive at the knowledge of a faculty, for the faculty itself. The air I breathe is the condition of my life, not its cause. We could never have learned that we had eyes but by the process of seeing; yet having seen we know that the eyes must have pre-existed in order to render the process of sight possible. Let us cross-examine Hartley's scheme under the guidance of this distinction; and we shall discover, that contemporaneity, (Leibnitz's Lex Continui,) is the limit and condition of the laws of mind, itself being rather a law of matter, at least of phaenomena considered as material. At the utmost, it is to thought the same, as the law of gravitation is to loco-motion. In every voluntary movement we first counteract gravitation, in order to avail ourselves of it. It must exist, that there may be a something to be counteracted, and which, by its re-action, may aid the force that is exerted to resist it. Let us consider what we do when we leap. We first resist the gravitating power by an act purely voluntary, and then by another act, voluntary in part, we yield to it in order to alight on the spot, which we had previously proposed to ourselves. Now let a man watch his mind while he is composing; or, to take a still more common case, while he is trying to recollect a name; and he will find the process completely analogous. Most of my readers will have observed a small water-insect on the surface of rivulets, which throws a cinque-spotted shadow fringed with prismatic colours on the sunny bottom of the brook; and will have noticed, how the little animal wins its way up against the stream, by alternate pulses of active and passive motion, now resisting the current, and now yielding to it in order to gather strength and a momentary fulcrum for a further propulsion. This is no unapt emblem of the mind's self-experience in the act of thinking. There are evidently two powers at work, which relatively to each other are active and passive; and this is not possible without an intermediate faculty, which is at once both active and passive. In philosophical language, we 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
