It is a well-known fact that few persons can stand safely on the edge of a precipice, or walk along the parapet wall of a house, without being in danger of throwing themselves down; not, we presume, from a principle of self-preservation; but in consequence of a strong idea having taken possession of the mind from which it cannot well escape, which absorbs every other consideration, and confounds and overrules all self-regards. The impulse cannot in this case be resolved into a desire to remove the uneasiness of fear, for the only danger arises from the fear. We have been told by a person not at all given to exaggeration, that he once felt a strong propensity to throw himself into a cauldron of boiling lead, into which he was looking. These are what Shakspeare calls ‘the toys of desperation.’ People sometimes marry, and even fall in love on this principle—that is, through mere apprehension, or what is called a fatality. In like manner, we find instances of persons who are, as it were, naturally delighted with whatever is disagreeable—who catch all sorts of unbecoming tones and gestures—who always say what they should not, and what they do not mean to say—in whom intemperance of imagination and incontinence of tongue are a disease, and who are governed by an almost infallible instinct of absurdity.

The love of imitation has the same general source. We dispute for ever about Hogarth, and the question can never be decided according to the common ideas on the subject of taste. His pictures appeal to the love of truth, not to the sense of beauty: but the one is as much an essential principle of our nature as the other. They fill up the void of the mind; they present an everlasting succession and variety of ideas. There is a fine observation somewhere made by Aristotle, that the mind has a natural appetite of curiosity or desire to know; and most of that knowledge which comes in by the eye, for this presents us with the greatest variety of differences. Hogarth is relished only by persons of a certain strength of mind and penetration into character; for the subjects in themselves are not pleasing, and this objection is only redeemed by the exercise and activity which they give to the understanding. The great difference between what is meant by a severe and an effeminate taste or style, depends on the distinction here made.

Our teasing ourselves to recollect the names of places or persons we have forgotten, the love of riddles and of abstruse philosophy, are all illustrations of the same general principle of curiosity, or the love of intellectual excitement. Again, our impatience to be delivered of a secret that we know; the necessity which lovers have for confidants, auricular confession, and the declarations so commonly made by criminals of their guilt, are effects of the involuntary power exerted by the imagination over the feelings. Nothing can be more untrue, than that the whole course of our ideas, passions, and pursuits, is regulated by a regard to self-interest. Our attachment to certain objects is much oftener in proportion to the strength of the impression they make on us, to their power of riveting and fixing the attention, than to the gratification we derive from them. We are, perhaps, more apt to dwell upon circumstances that excite disgust and shock our feelings, than on those of an agreeable nature. This, at least, is the case where this disposition is particularly strong, as in people of nervous feelings and morbid habits of thinking. Thus the mind is often haunted with painful images and recollections, from the hold they have taken of the imagination. We cannot shake them off, though we strive to do it: nay, we even court their company; we will not part with them out of our presence; we strain our aching sight after them; we anxiously recall every feature, and contemplate them in all their aggravated colours. There are a thousand passions and fancies that thwart our purposes, and disturb our repose. Grief and fear are almost as welcome inmates of the breast as hope or joy, and more obstinately cherished. We return to the objects which have excited them, we brood over them, they become almost inseparable from the mind, necessary to it; they assimilate all objects to the gloom of our own thoughts, and make the will a party against itself. This is one chief source of most of the passions that prey like vultures on the heart, and embitter human life. We hear moralists and divines perpetually exclaiming, with mingled indignation and surprise, at the folly of mankind in obstinately persisting in these tormenting and violent passions, such as envy, revenge, sullenness, despair, etc. This is to them a mystery; and it will always remain an inexplicable one, while the love of happiness is considered as the only spring of human conduct and desires.[8]

The love of power or action is another independent principle of the human mind, in the different degrees in which it exists, and which are not by any means in exact proportion to its physical sensibility. It seems evidently absurd to suppose that sensibility to pleasure or pain is the only principle of action. It is almost too obvious to remark, that sensibility alone, without an active principle in the mind, could never produce action. The soul might lie dissolved in pleasure, or be agonised with woe; but the impulses of feeling, in order to excite passion, desire, or will, must be first communicated to some other faculty. There must be a principle, a fund of activity somewhere, by and through which our sensibility operates; and that this active principle owes all its force, its precise degree of direction, to the sensitive faculty, is neither self-evident nor true. Strength of will is not always nor generally in proportion to strength of feeling. There are different degrees of activity, as of sensibility, in the mind; and our passions, characters, and pursuits, often depend no less upon the one than on the other. We continually make a distinction in common discourse between sensibility and irritability, between passion and feeling, between the nerves and muscles; and we find that the most voluptuous people are in general the most indolent. Every one who has looked closely into human nature must have observed persons who are naturally and habitually restless in the extreme, but without any extraordinary susceptibility to pleasure or pain, always making or finding excuses to do something—whose actions constantly outrun the occasion, and who are eager in the pursuit of the greatest trifles—whose impatience of the smallest repose keeps them always employed about nothing—and whose whole lives are a continued work of supererogation. There are others, again, who seem born to act from a spirit of contradiction only, that is, who are ready to act not only without a reason, but against it—who are ever at cross-purposes with themselves and others—who are not satisfied unless they are doing two opposite things at a time—who contradict what you say, and if you assent to them, contradict what they have said—who regularly leave the pursuit in which they are successful to engage in some other in which they have no chance of success—who make a point of encountering difficulties and aiming at impossibilities, that there may be no end of their exhaustless task: while there is a third class whose vis inertiæ scarcely any motives can overcome—who are devoured by their feelings, and the slaves of their passions, but who can take no pains and use no means to gratify them—who, if roused to action by any unforeseen accident, require a continued stimulus to urge them on—who fluctuate between desire and want of resolution—whose brightest projects burst like a bubble as soon as formed—who yield to every obstacle—who almost sink under the weight of the atmosphere—who cannot brush aside a cobweb in their path, and are stopped by an insect’s wing. Indolence is want of will—the absence or defect of the active principle—a repugnance to motion; and whoever has been much tormented with this passion, must, we are sure, have felt that the inclination to indulge it is something very distinct from the love of pleasure or actual enjoyment. Ambition is the reverse of indolence, and is the love of power or action in great things. Avarice, also, as it relates to the acquisition of riches, is, in a great measure, an active and enterprising feeling; nor does the hoarding of wealth, after it is acquired, seem to have much connection with the love of pleasure. What is called niggardliness, very often, we are convinced from particular instances that we have known, arises less from a selfish principle than from a love of contrivance—from the study of economy as an art, for want of a better—from a pride in making the most of a little, and in not exceeding a certain expense previously determined upon; all which is wilfulness, and is perfectly consistent, as it is frequently found united, with the utmost lavish expenditure and the utmost disregard for money on other occasions. A miser may, in general, be looked upon as a particular species of virtuoso. The constant desire in the rich to leave wealth in large masses, by aggrandising some branch of their families, or sometimes in such a manner as to accumulate for centuries, shows that the imagination has a considerable share in this passion. Intemperance, debauchery, gluttony, and other vices of that kind, may be attributed to an excess of sensuality or gross sensibility; though, even here, we think it evident that habits of intoxication are produced quite as much by the strength as by the agreeableness of the excitement; and with respect to some other vicious habits, curiosity makes many more votaries than inclination. The love of truth, when it predominates, produces inquisitive characters, the whole tribe of gossips, tale-bearers, harmless busybodies, your blunt honest creatures, who never conceal what they think, and who are the more sure to tell it you the less you want to hear it—and now and then a philosopher.

Our passions in general are to be traced more immediately to the active part of our nature, to the love of power, or to strength of will. Such are all those which arise out of the difficulty of accomplishment, which become more intense from the efforts made to attain the object, and which derive their strength from opposition. Mr. Hobbes says well on this subject:

‘But for an utmost end, in which the ancient philosophers placed felicity, and disputed much concerning the way thereto, there is no such thing in this world, nor way to it, more than to Utopia; for while we live, we have desires, and desire presupposeth a further end. Seeing all delight is appetite, and desire of something further, there can be no contentment but in proceeding, and therefore we are not to marvel, when we see that as men attain to more riches, honour, or other power, so their appetite continually groweth more and more; and when they are come to the utmost degree of some kind of power they pursue some other, as long as in any kind they think themselves behind any other. Of those, therefore, that have attained the highest degree of honour and riches, some have affected mastery, in some art, as Nero in music and poetry, Commodus in the art of a gladiator; and such as affect not some such thing, must find diversion and recreation of their thoughts in the contention either of play or business, and men justly complain as of a great grief that they know not what to do. Felicity, therefore, by which we mean continual delight, consists not in having prospered, but in prospering.’

This account of human nature, true as it is, would be a mere romance, if physical sensibility were the only faculty essential to man, that is, if we were the slaves of voluptuous indolence. But our desires are kindled by their own heat, the will is urged on by a restless impulse, and without action, enjoyment becomes insipid. The passions of men are not in proportion only to their sensibility, or to the desirableness of the object, but to the violence and irritability of their tempers, and the obstacles to their success. Thus an object to which we were almost indifferent while we thought it in our power, often excites the most ardent pursuit or the most painful regret, as soon as it is placed out of our reach. How eloquently is the contradiction between our desires and our success described in Don Quixote, where it is said of the lover, that ‘he courted a statue, hunted the wind, cried aloud to the desert!’

The necessity of action to the mind, and the keen edge it gives to our desires, is shown in the different value we set on past and future objects. It is commonly, and we might almost say universally, supposed, that there is an essential difference in the two cases. In this instance, however, the strength of our passions has converted an evident absurdity into one of the most inveterate prejudices of the human mind. That the future is really or in itself of more consequence than the past, is what we can neither assent to nor even conceive. It is true, the past has ceased to be, and is no longer anything, except to the mind; but the future is still to come, and has an existence in the mind only. The one is at an end, the other has not even had a beginning; both are purely ideal: so that this argument would prove that the present only is of any real value, and that both past and future objects are equally indifferent, alike nothing. Indeed, the future is, if possible, more imaginary than the past; for the past may in some sense be said to exist in its consequences; it acts still; it is present to us in its effects; the mouldering ruins and broken fragments still remain; but of the future there is no trace. What a blank does the history of the world for the next six thousand years present to the mind, compared with that of the last? All that strikes the imagination, or excites any interest in the mighty scene is what has been. Neither in reality, then, nor as a subject of general contemplation, has the future any advantage over the past; but with respect to our own passions and pursuits it has. We regret the pleasures we have enjoyed, and eagerly anticipate those which are to come; we dwell with satisfaction on the evils from which we have escaped, and dread future pain. The good that is past is like money that is spent, which is of no use, and about which we give no further concern. The good we expect is like a store yet untouched, in the enjoyment of which we promise ourselves infinite gratification. What has happened to us we think of no consequence—what is to happen to us, of the greatest. Why so? Because the one is in our power, and the other not; because the efforts of the will to bring an object to pass or to avert it, strengthen our attachment to or our aversion from that object; because the habitual pursuit of any purpose redoubles the ardour of our pursuit, and converts the speculative and indolent interest we should otherwise take in it into real passion. Our regrets, anxiety, and wishes, are thrown away upon the past, but we encourage our disposition to exaggerate the importance of the future, as of the utmost use in aiding our resolutions and stimulating our exertions.

It in some measure confirms this theory, that men attach more or less importance to past and future events, according as they are more or else engaged in action and the busy scenes of life. Those who have a fortune to make, or are in pursuit of rank and power, are regardless of the past, for it does not contribute to their views: those who have nothing to do but to think, take nearly the same interest in the past as in the future. The contemplation of the one is as delightful and real as of the other. The season of hope comes to an end, but the remembrance of it is left. The past still lives in the memory of those who have leisure to look back upon the way that they have trod, and can from it ‘catch glimpses that may make them less forlorn.’ The turbulence of action and uneasiness of desire must dwell upon the future; it is only amidst the innocence of shepherds, in the simplicity of the pastoral ages, that a tomb was found with this inscription—‘I also was an Arcadian!

We feel that some apology is necessary for having thus plunged our readers all at once into the middle of metaphysics. If it should be asked what use such studies are of, we might answer with Hume, perhaps of none, except that there are certain persons who find more entertainment in them than in any other. An account of this matter, with which we were amused ourselves, and which may therefore amuse others, we met with some time ago in a metaphysical allegory, which begins in this manner:
