SECT. I OF LIBERTY AND NECESSITY
Actions are by their very nature temporary and perishing; and where they proceed not from some cause in the characters and disposition of the person, who performed them, they infix not themselves upon him, and can neither redound to his honour, if good, nor infamy, if evil. The action itself may be blameable; it may be contrary to all the rules of morality and religion: But the person is not responsible for it; and as it proceeded from nothing in him, that is durable or constant, and leaves nothing of that nature behind it, it is impossible he can, upon its account, become the object of punishment or vengeance. According to the hypothesis of liberty, therefore, a man is as pure and untainted, after having committed the most horrid crimes, as at the first moment of his birth, nor is his character any way concerned in his actions; since they are not derived from it, and the wickedness of the one can never be used as a proof of the depravity of the other. It is only upon the principles of necessity, that a person acquires any merit or demerit from his actions, however the common opinion may incline to the contrary.
But so inconsistent are men with themselves, that though they often assert, that necessity utterly destroys all merit and demerit either towards mankind or superior powers, yet they continue still to reason upon these very principles of necessity in all their judgments concerning this matter. Men are not blamed for such evil actions as they perform ignorantly and casually, whatever may be their consequences. Why? but because the causes of these actions are only momentary, and terminate in them alone. Men are less blamed for such evil actions, as they perform hastily and unpremeditately, than for such as proceed from thought and deliberation. For what reason? but because a hasty temper, though a constant cause in the mind, operates only by intervals, and infects not the whole character. Again, repentance wipes off every crime, especially if attended with an evident reformation of life and manners. How is this to be accounted for? But by asserting that actions render a person criminal, merely as they are proofs of criminal passions or principles in the mind; and when by any alteration of these principles they cease to be just proofs, they likewise cease to be criminal. But according to the doctrine of liberty or chance they never were just proofs, and consequently never were criminal.
Nothing is more usual in philosophy, and even in common life, than to talk of the combat of passion and reason, to give the preference to reason, and assert that men are only so far virtuous as they conform themselves to its dictates. Every rational creature, it is said, is obliged to regulate his actions by reason; and if any other motive or principle challenge the direction of his conduct, he ought to oppose it, till it be entirely subdued, or at least brought to a conformity with that superior principle. On this method of thinking the greatest part of moral philosophy, antient and modern, seems to be founded; nor is there an ampler field, as well for metaphysical arguments, as popular declamations, than this supposed pre-eminence of reason above passion. The eternity, invariableness, and divine origin of the former have been displayed to the best advantage: The blindness, unconstancy, and deceitfulness of the latter have been as strongly insisted on. In order to shew the fallacy of all this philosophy, I shall endeavour to prove first, that reason alone can never be a motive to any action of the will; and secondly, that it can never oppose passion in the direction of the will.
The understanding exerts itself after two different ways, as it judges from demonstration or probability; as it regards the abstract relations of our ideas, or those relations of objects, of which experience only gives us information. I believe it scarce will be asserted, that the first species of reasoning alone is ever the cause of any action. As its proper province is the world of ideas, and as the will always places us in that of realities, demonstration and volition seem, upon that account, to be totally removed, from each other. Mathematics, indeed, are useful in all mechanical operations, and arithmetic in almost every art and profession: But it is not of themselves they have any influence: Mechanics are the art of regulating the motions of bodies to some designed end or purpose; and the reason why we employ arithmetic in fixing the proportions of numbers, is only that we may discover the proportions of their influence and operation. A merchant is desirous of knowing the sum total of his accounts with any person: Why? but that he may learn what sum will have the same effects in paying his debt, and going to market, as all the particular articles taken together. Abstract or demonstrative reasoning, therefore, never influences any of our actions, but only as it directs our judgment concerning causes and effects; which leads us to the second operation of the understanding.
It is obvious, that when we have the prospect of pain or pleasure from any object, we feel a consequent emotion of aversion or propensity, and are carryed to avoid or embrace what will give us this uneasines or satisfaction. It is also obvious, that this emotion rests not here, but making us cast our view on every side, comprehends whatever objects are connected with its original one by the relation of cause and effect. Here then reasoning takes place to discover this relation; and according as our reasoning varies, our actions receive a subsequent variation. But it is evident in this case that the impulse arises not from reason, but is only directed by it. It is from the prospect of pain or pleasure that the aversion or propensity arises towards any object: And these emotions extend themselves to the causes and effects of that object, as they are pointed out to us by reason and experience. It can never in the least concern us to know, that such objects are causes, and such others effects, if both the causes and effects be indifferent to us. Where the objects themselves do not affect us, their connexion can never give them any influence; and it is plain, that as reason is nothing but the discovery of this connexion, it cannot be by its means that the objects are able to affect us.
Since reason alone can never produce any action, or give rise to volition, I infer, that the same faculty is as incapable of preventing volition, or of disputing the preference with any passion or emotion. This consequence is necessary. It is impossible reason could have the latter effect of preventing volition, but by giving an impulse in a contrary direction to our passion; and that impulse, had it operated alone, would have been able to produce volition. Nothing can oppose or retard the impulse of passion, but a contrary impulse; and if this contrary impulse ever arises from reason, that latter faculty must have an original influence on the will, and must be able to cause, as well as hinder any act of volition. But if reason has no original influence, it is impossible it can withstand any principle, which has such an efficacy, or ever keep the mind in suspence a moment. Thus it appears, that the principle, which opposes our passion, cannot be the same with reason, and is only called so in an improper sense. We speak not strictly and philosophically when we talk of the combat of passion and of reason. Reason is, and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them. As this opinion may appear somewhat extraordinary, it may not be improper to confirm it by some other considerations.
A passion is an original existence, or, if you will, modification of existence, and contains not any representative quality, which renders it a copy of any other existence or modification. When I am angry, I am actually possest with the passion, and in that emotion have no more a reference to any other object, than when I am thirsty, or sick, or more than five foot high. It is impossible, therefore, that this passion can be opposed by, or be contradictory to truth and reason; since this contradiction consists in the disagreement of ideas, considered as copies, with those objects, which they represent. What may at first occur on this head, is, that as nothing can be contrary to truth or reason, except what has a reference to it, and as the judgments of our understanding only have this reference, it must follow, that passions can be contrary to reason only so far as they are accompanyed with some judgment or opinion. According to this principle, which is so obvious and natural, it is only in two senses, that any affection can be called unreasonable. First, When a passion, such as hope or fear, grief or joy, despair or security, is founded on the supposition or the existence of objects, which really do not exist. Secondly, When in exerting any passion in action, we chuse means insufficient for the designed end, and deceive ourselves in our judgment of causes and effects. Where a passion is neither founded on false suppositions, nor chuses means insufficient for the end, the understanding can neither justify nor condemn it. It is not contrary to reason to prefer the destruction of the whole world to the scratching of my finger. It is not contrary to reason for me to chuse my total ruin, to prevent the least uneasiness of an Indian or person wholly unknown to me. It is as little contrary to reason to prefer even my own acknowledgeed lesser good to my greater, and have a more ardent affection for the former than the latter. A trivial good may, from certain circumstances, produce a desire superior to what arises from the greatest and most valuable enjoyment; nor is there any thing more extraordinary in this, than in mechanics to see one pound weight raise up a hundred by the advantage of its situation. In short, a passion must be accompanyed with some false judgment in order to its being unreasonable; and even then it is not the passion, properly speaking, which is unreasonable, but the judgment.
The consequences are evident. Since a passion can never, in any sense, be called unreasonable, but when founded on a false supposition or when it chuses means insufficient for the designed end, it is impossible, that reason and passion can ever oppose each other, or dispute for the government of the will and actions. The moment we perceive the falshood of any supposition, or the insufficiency of any means our passions yield to our reason without any opposition. I may desire any fruit as of an excellent relish; but whenever you convince me of my mistake, my longing ceases. I may will the performance of certain actions as means of obtaining any desired good; but as my willing of these actions is only secondary, and founded on the supposition, that they are causes of the proposed effect; as soon as I discover the falshood of that supposition, they must become indifferent to me.
It is natural for one, that does not examine objects with a strict philosophic eye, to imagine, that those actions of the mind are entirely the same, which produce not a different sensation, and are not immediately distinguishable to the feeling and perception. Reason, for instance, exerts itself without producing any sensible emotion; and except in the more sublime disquisitions of philosophy, or in the frivolous subtilties of the school, scarce ever conveys any pleasure or uneasiness. Hence it proceeds, that every action of the mind, which operates with the same calmness and tranquillity, is confounded with reason by all those, who judge of things from the first view and appearance. Now it is certain, there are certain calm desires and tendencies, which, though they be real passions, produce little emotion in the mind, and are more known by their effects than by the immediate feeling or sensation. These desires are of two kinds; either certain instincts originally implanted in our natures, such as benevolence and resentment, the love of life, and kindness to children; or the general appetite to good, and aversion to evil, considered merely as such. When any of these passions are calm, and cause no disorder in the soul, they are very readily taken for the determinations of reason, and are supposed to proceed from the same faculty, with that, which judges of truth and falshood. Their nature and principles have been supposed the same, because their sensations are not evidently different.
Beside these calm passions, which often determine the will, there are certain violent emotions of the same kind, which have likewise a great influence on that faculty. When I receive any injury from another, I often feel a violent passion of resentment, which makes me desire his evil and punishment, independent of all considerations of pleasure and advantage to myself. When I am immediately threatened with any grievous ill, my fears, apprehensions, and aversions rise to a great height, and produce a sensible emotion. The common error of metaphysicians has lain in ascribing the direction of the will entirely to one of these principles, and supposing the other to have no influence. Men often act knowingly against their interest: For which reason the view of the greatest possible good does not always influence them. Men often counter-act a violent passion in prosecution of their interests and designs: It is not therefore the present uneasiness alone, which determines them. In general we may observe, that both these principles operate on the will; and where they are contrary, that either of them prevails, according to the general character or present disposition of the person. What we call strength of mind, implies the prevalence of the calm passions above the violent; though we may easily observe, there is no man so constantly possessed of this virtue, as never on any occasion to yield to the sollicitations of passion and desire. From these variations of temper proceeds the great difficulty of deciding concerning the actions and resolutions of men, where there is any contrariety of motives and passions.
SECT. IV OF THE CAUSES OF THE VIOLENT PASSIONS There is not in philosophy a subject of more nice speculation than this of the different causes and effects of the calm and violent passions. It is evident passions influence not the will in proportion to their violence, or the disorder they occasion in the temper; but on the contrary, that when a passion has once become a settled principle of action, and is the predominant inclination of the soul, it commonly produces no longer any sensible agitation. As repeated custom and its own force have made every thing yield to it, it directs the actions and conduct without that opposition and emotion, which so naturally attend every momentary gust of passion. We must, therefore, distinguish betwixt a calm and a weak passion; betwixt a violent and a strong one. But notwithstanding this, it is certain, that when we would govern a man, and push him to any action, it will commonly be better policy to work upon the violent than the calm passions, and rather take him by his inclination, than what is vulgarly called his reason. We ought to place the object in such particular situations as are proper to encrease the violence of the passion. For we may observe, that all depends upon the situation of the object, and that a variation in this particular will be able to change the calm and the violent passions into each other. Both these kinds of passions pursue good, and avoid evil; and both of them are encreased or diminished by the encrease or diminution of the good or evil. But herein lies the difference betwixt them: The same good, when near, will cause a violent passion, which, when remote, produces only a calm one. As this subject belongs very properly to the present question concerning the will, we shall here examine it to the bottom, and shall consider some of those circumstances and situations of objects, which render a passion either calm or violent.
It is a remarkable property of human nature, that any emotion, which attends a passion, is easily converted into it, though in their natures they be originally different from, and even contrary to each other. It is true; in order to make a perfect union among passions, there is always required a double relation of impressions and ideas; nor is one relation sufficient for that purpose. But though this be confirmed by undoubted experience, we must understand it with its proper limitations, and must regard the double relation, as requisite only to make one passion produce another. When two passions are already produced by their separate causes, and are both present in the mind, they readily mingle and unite, though they have but one relation, and sometimes without any. The predominant passion swallows up the inferior, and converts it into itself. The spirits, when once excited, easily receive a change in their direction; and it is natural to imagine this change will come from the prevailing affection. The connexion is in many respects closer betwixt any two passions, than betwixt any passion and indifference.
When a person is once heartily in love, the little faults and caprices of his mistress, the jealousies and quarrels, to which that commerce is so subject; however unpleasant and related to anger and hatred; are yet found to give additional force to the prevailing passion. It is a common artifice of politicians, when they would affect any person very much by a matter of fact, of which they intend to inform him, first to excite his curiosity; delay as long as possible the satisfying it; and by that means raise his anxiety and impatience to the utmost, before they give him a full insight into the business. They know that his curiosity will precipitate him into the passion they design to raise, and assist the object in its influence on the mind. A soldier advancing to the battle, is naturally inspired with courage and confidence, when he thinks on his friends and fellow-soldiers; and is struck with fear and terror, when he reflects on the enemy. Whatever new emotion, therefore, proceeds from the former naturally encreases the courage; as the same emotion, proceeding from the latter, augments the fear; by the relation of ideas, and the conversion of the inferior emotion into the predominant. Hence it is that in martial discipline, the uniformity and lustre of our habit, the regularity of our figures and motions, with all the pomp and majesty of war, encourage ourselves and allies; while the same objects in the enemy strike terror into us, though agreeable and beautiful in themselves.
Since passions, however independent, are naturally transfused into each other, if they are both present at the same time; it follows, that when good or evil is placed in such a situation, as to cause any particular emotion, beside its direct passion of desire or aversion, that latter passion must acquire new force and violence. This happens, among other cases, whenever any object excites contrary passions. For it is observable that an opposition of passions commonly causes a new emotion in the spirits, and produces more disorder, than the concurrence of any two affections of equal force. This new emotion is easily converted into the predominant passion, and encreases its violence, beyond the pitch it would have arrived at had it met with no opposition. Hence we naturally desire what is forbid, and take a pleasure in performing actions, merely because they are unlawful. The notion of duty, when opposite to the passions, is seldom able to overcome them; and when it fails of that effect, is apt rather to encrease them, by producing an opposition in our motives and principles. The same effect follows whether the opposition arises from internal motives or external obstacles. The passion commonly acquires new force and violence in both cases. The efforts, which the mind makes to surmount the obstacle, excite the spirits and inliven the passion.
Uncertainty has the same influence as opposition. The agitation of the thought; the quick turns it makes from one view to another; the variety of passions, which succeed each other, according to the different views; All these produce an agitation in the mind, and transfuse themselves into the predominant passion. There is not in my opinion any other natural cause, why security diminishes the passions, than because it removes that uncertainty, which encreases them. The mind, when left to itself, immediately languishes; and in order to preserve its ardour, must be every moment supported by a new flow of passion. For the same reason, despair, though contrary to security, has a like influence. It is certain nothing more powerfully animates any affection, than to conceal some part of its object by throwing it into a kind of shade, which at the same time that it chews enough to pre-possess us in favour of the object, leaves still some work for the imagination. Besides that obscurity is always attended with a kind of uncertainty; the effort, which the fancy makes to compleat the idea, rouzes the spirits, and gives an additional force to the passion. As despair and security, though contrary to each other, produce the same effects; so absence is observed to have contrary effects, and in different circumstances either encreases or diminishes our affections. The Duc de La Rochefoucault has very well observed, that absence destroys weak passions, but encreases strong; as the wind extinguishes a candle, but blows up a fire. Long absence naturally weakens our idea, and diminishes the passion: But where the idea is so strong and lively as to support itself, the uneasiness, arising from absence, encreases the passion and gives it new force and violence.
