HAVING now finished the theoretical part of our enquiry,BOOK IV. CHAP. V. so far as appeared to be necessary to afford a foundation for our reasoning respecting the different provisions of political BOOK IV. CHAP. V. institution, we might directly proceed to the consideration of those provisions. It will not however be useless to pause in this place, in order to consider those general principles of the human mind, which are most intimately connected with the topics of political reasoning* .
None of these principles seems to be of greater importance than that which affirms that all actions are necessary.
Importance of the question Most of the reasonings upon which we have hitherto been employed, though perhaps constantly built upon this doctrine as a postulate, will yet by their intrinsic evidence, however inconsistently with his opinion upon this primary topic, be admitted by the advocate of free will. But it ought not to be the present design of political enquirers to treat the questions that may present themselves superficially. It will be found upon maturer reflection that this doctrine of moral necessity includes in it consequences of the highest moment, and leads to a bold and comprehensive view of man in society, which cannot possibly be entertained by him who has embraced the opposite opinion. Severe method would have required that this proposition should have been established in the first instance, as an indispensible foundation of moral reasoning of every sort. But there are wellBOOK IV. CHAP. V. disposed persons, who notwithstanding the evidence with which it is attended, have been alarmed at its consequences; and it was perhaps proper, in compliance with their mistake, to shew that the moral reasonings of this work did not stand in need of this support, in any other sense than moral reasonings do upon every other subject.
To the right understanding of any arguments that may beDefinition of necessity. adduced under this head, it is requisite that we should have a clear idea of the meaning of the term necessity. He who affirms that all actions are necessary, means, that, if we form a just and complete view of all the circumstances in which a living or intelligent being is placed, we shall find that he could not in any moment of his existence have acted otherwise than he has acted. According to this assertion there is in the transactions of mind nothing loose, precarious and uncertain. Upon this question the advocate of liberty in the philosophical sense must join issue. He must, if he mean any thing, deny this certainty of conjunction between moral antecedents and consequents. Where all is constant and invariable, and the events that arise uniformly flow from the circumstances in which they originate, there can be no liberty.
It is acknowledged that in the events of the material universe everyWhy supposed to existBOOK IV. CHAP. V. in the operations of the material universe thing is subjected to this necessity. The tendency of investigation and enquiryrelatively to this topic of human knowledge has been, more effectually to excludechance, as our improvements extended. Let us consider what is the species ofevidence that has satisfied philosophers upon this point. Their only valid groundof reasoning has been from experience. The argument which has induced mankindto conceive of the universe as governed by certain laws, and to entertain theidea of necessary connexion between successive events, has been an observed similarityin the order of succession. If, when we had once remarked two events succeedingeach other, we had never had occasion to see that individual succession repeated;if we saw innumerable events in perpetual progression without any apparent order,so that all our observation would not enable us, when we beheld one, to pronouncethat another of such a particular class might be expected to follow; we shouldnever have conceived of the existence of necessary connexion, or have had anidea corresponding to the term cause.
Hence it follows that all that strictly speaking we know of the material universe is this succession of events. Uniform succession irresistibly forces upon the mind the idea of abstract connexion. When we see the sun constantly rise in the morning and set at night, and have had occasion to observe this phenomenon invariably taking place through the whole period of our existence, we cannot avoid believing that there is some cause producingBOOK IV. CHAP. V. this uniformity of event. But the principle or virtue by which one event is conjoined to another we never see.
Let us take some familiar illustrations of this truth. Can it be imagined that any man by the inspection and analysis of gunpowder would have been enabled, previously to experience, to predict its explosion? Would he previously to experience have been enabled to predict, that one piece of marble having a flat and polished surface might with facility be protruded along another in a horizontal, but would with considerable pertinacity resist separation in a perpendicular direction? The simplest phenomena of the most hourly occurrence were originally placed at an equal distance from human sagacity.
There is a certain degree of obscurity incident to this subject arising from the following circumstance. All human knowledge is the result of perception. We know nothing of any substance but by experience. If it produced no effects, it would be no subject of human intelligence. We collect a considerable number of these effects, and, by their perceived uniformity having reduced them into general classes, form a general idea annexed to the subject that produces them. It must be admitted, that a definition of any substance, that is, any thing that deserves to be called knowledge respecting it, will enable us to predict some of its future possible effects, and that for this plain reason, that defi BOOK IV. CHAP. V. nition is prediction under another name. But, though, when we have gained the idea of impenetrability as a general phenomenon of matter, we can predict some of its effects, there are others which we cannot predict: or in other words, we know none of its effects but such as we have actually remarked, added to an expectation that similar events will arise under similar circumstances, proportioned to the constancy with which they have been observed to take place in our past experience. Finding as we do by repeated experiments, that material substances have the property of resistance, and that one substance in a state of rest, when impelled by another, passes into a state of motion, we are still in want of more particular observation to enable us to predict the specific effects that will follow from this impulse in each of the bodies. Enquire of a man who knows nothing more of matter than its general property of impenetrability, what will be the result of one ball of matter impinging upon another, and you will soon find how little this general property can inform him of the particular laws of motion. We suppose him to know that it will communicate motion to the second ball. But what quantity of motion will it communicate? What effects will the impulse produce upon the impelling ball? Will it continue to move in the same direction? will it recoil in the opposite direction? will it fly off obliquely, or will it subside into a state of rest? All these events will appear equally probable to him whom a series of observations upon the past has not instructed as to what he is to expect from the future.
From these remarks we may sufficiently collect what is theBOOK IV. CHAP. V. species of knowledge we possess respecting the laws of the material universe. No experiments we are able to make, no reasonings we are able to deduce, can ever instruct us in the principle of causation, or shew us for what reason it is that one event has, in every instance in which it has been known to occur, been the precursor of another event of a certain given description. Yet we reasonably believe that these events are bound together by a perfect necessity, and exclude from our ideas of matter and motion the supposition of chance or an uncaused event. Association of ideas obliges us, after having seen two events perpetually conjoined, to pass, as soon as one of them occurs, to the recollection of the other: and, in cases where this transition never deceives us, but the ideal succession is always found to be an exact copy of the future event, it is impossible that this species of foresight should not convert into a general foundation of reasoning. We cannot take a single step upon this subject, which does not partake of the species of operation we denominate abstraction. Till we have been led to consider the rising of the sun to-morrow as an incident of the same species as its rising today, we cannot deduce from it similar consequences. It is the business of science to carry this task of generalisation to its farthest extent, and to reduce the diversified events of the universe to a finall number of original principles.
Let us proceed to apply these reasonings concerning matter toThe case of the operaBOOK IV. CHAP. V. tions of mind is parallel the illustration of the theory of mind. Is it possible in this latter theory, as in the former subject, to discover any general principles? Can intellect be made a topic of science? Are we able to reduce the multiplied phenomena of mind to any certain standard of reasoning? If the affirmative of these questions be conceded, the inevitable consequence appears to be, that mind, as well as matter, exhibits a constant conjunction of events, and affords a reasonable presumption to the necessary connexion of those events. It is of no importance that we cannot see the ground of that connexion, or imagine how propositions and reasoning, when presented to the mind of a percipient being, are able by necessary consequence to generate volition and animal motion; for, if there be any truth in the above reasonings, we are equally incapable of perceiving the ground of connexion between any two events in the material universe, the common and received opinion that we do perceive such ground of connexion being in reality nothing more than a vulgar prejudice.
Indications of necessity: That mind is a topic of science may be argued from all those branches of literature and enquiry which have mind for their in history: subject. What species of amusement or instruction would history afford us, if there were no ground of inference from moral causes to effects, if certain temptations and inducements did not in all ages and climates produce a certain series of actions, if we were unable to trace connexion and a principle of unity in men's tempers, propensities and transactions? The amusement would be inferior to that which we derive from the perusal of a chronologicalBOOK IV. CHAP. V. table, where events have no order but that of time; since, however the chronologist may neglect to mark the internal connexion between successive transactions, the mind of the reader is busied in supplying that connexion from memory or imagination: but the very idea of such connexion would never have suggested itself, if we had never found the source of that idea in experience. The instruction arising from the perusal of history would be absolutely none; since instruction implies in its very nature the classing and generalising of objects. But, upon the supposition on which we are arguing, all objects would be unconnected and disjunct, without the possibility of affording any grounds of reasoning or principles of science.
The idea correspondent to the term character inevitably includesin our judgments of character: in it the assumption of necessary connexion. The character of any man is the result of a long series of impressions communicated to his mind, and modifying it in a certain manner, so as to enable us, from a number of these modifications and impressions being given, to predict his conduct. Hence arise his temper and habits, respecting which we reasonably conclude, that they will not be abruptly superseded and reversed; and that, if they ever be reversed, it will not be accidentally, but in consequence of some strong reason persuading, or some extraordinary event modifying his mind. If there were not this original and essential connexion between motives and actions, and, which BOOK IV. CHAP. V. forms one particular branch of this principle, between men's past and future actions, there could be no such thing as character, or as a ground of inference enabling us to predict what men would be from what they have been.
in our schemes of policy: From the same idea of necessary connexion arise all the schemes of policy, in consequence of which men propose to themselves by a certain plan of conduct to prevail upon others to become the tools and instruments of their purposes. All the arts of courtship and flattery, of playing upon men's hopes and fears, proceed upon the supposition that mind is subject to certain laws, and that, provided we be skilful and assiduous enough in applying the cause, the effect will inevitably follow.
in our ideas of moral discipline Lastly, the idea of moral discipline proceeds entirely upon this principle. If I carefully persuade, exhort, and exhibit motives to another, it is because I believe that motives have a tendency to influence his conduct. If I reward or punish him, either with a view to his own improvement or as an example to others, it is because I have been led to believe that rewards and punishments are calculated in their own nature to affect the sentiments and practices of mankind.
Objection from the fallibility of our expectations in human conduct There is but one conceivable objection against the inference from these premises to the necessity of human actions. It may be alledged, that “though there is a real connexion between motives and actions, yet that this connexion may not amountBOOK IV. CHAP. V. to a certainty, and that of consequence the mind still retains an inherent activity by which it can at pleasure dissolve this connexion. Thus for example, when I address argument and persuasion to my neighbour to induce him to adopt a certain species of conduct, I do it not with a certain expectation of success, and am not utterly disappointed if all my efforts fail of their effect. I make a reserve for a certain faculty of liberty he is supposed to possess, which may at last counteract the best digested projects.”
But in this objection there is nothing peculiar to the case ofAnswer mind. It is just so in matter. I see a part only of the premises, and therefore can pronounce only with uncertainty upon the conclusion. A philosophical experiment, which has succeeded a hundred times, may altogether fail upon the next trial. But what does the philosopher conclude from this? Not that there is a liberty of choice in his retort and his materials, by which they baffle the best formed expectations. Not that the connexion between effects and causes is imperfect, and that part of the effect happens from no cause at all. But that there was some other cause concerned whose operation he did not perceive, but which a fresh investigation will probably lay open to him. When the science of the material universe was in its infancy, men were sufficiently prompt to refer events to accident and chance; but the farther they have extended their enquiries and BOOK IV. CHAP. V. observation, the more reason they have found to conclude that every thing takes place according to necessary and universal laws.
The case is exactly parallel with respect to mind. The politician and the philosopher, however they may speculatively entertain the opinion of free will, never think of introducing it into their scheme of accounting for events. If an incident turn out otherwise than they expected, they take it for granted, that there was some unobserved bias, some habit of thinking, some prejudice of education, some singular association of ideas, that disappointed their prediction; and, if they be of an active and enterprising temper, they return, like the natural philosopher, to search out the secret spring of this unlooked for event.
Origin and universality of the sentiment of free will The reflections into which we have entered upon the doctrine of causes, not only afford us a simple and impressive argument in favour of the doctrine of necessity, but suggest a very obvious reason why the doctrine opposite to this has been in a certain degree the general opinion of mankind. It has appeared that the idea of necessary connexion between events of any sort is the lesson of experience, and the vulgar never arrive at the universal application of this principle even to the phenomena of the material universe. In the easiest and most familiar instances, such as the impinging of one ball of matter upon another and its consequences, they willingly admit the interference of chance, or an event uncaused. In this instance however, as both the impulseBOOK IV. CHAP. V. and its effects are subjects of observation to the senses, they readily imagine that they perceive the absolute principle which causes motion to be communicated from the first ball to the second. Now the very same prejudice and precipitate conclusion, which induce them to believe that they discover the principle of motion in objects of sense, act in an opposite direction with respect to such objects as cannot be subjected to the examination of sense. The manner in which an idea or proposition suggested to the mind of a percipient being produces animal motion they never see; and therefore readily conclude that there is no necessary connexion between these events.
But, if the vulgar will universally be found to be the advocatesThe sentiment of necessity also universal of free will, they are not less strongly, however inconsistently, impressed with the belief of the doctrine of necessity. It is a well known and a just observation, that, were it not for the existence of general laws to which the events of the material universe always conform, man could never have been either a reasoning or a moral being. The most considerable actions of our lives are directed by foresight. It is because he foresees the regular succession of the seasons, that the farmer sows his field, and after the expiration of a certain term expects a crop. There would be no kindness in my administering food to the hungry, and no injustice in my thrusting a drawn sword against the BOOK IV. CHAP. V. bosom of my friend, if it were not the established quality of food to nourish, and of a sword to wound.
But the regularity of events in the material universe will not of itself afford a sufficient foundation of morality and prudence. The voluntary conduct of our neighbours enters for a share into almost all those calculations upon which our own plans and determinations are founded. If voluntary conduct, as well as material impulse, were not subjected to general laws, included in the system of cause and effect, and a legitimate topic of prediction and foresight, the certainty of events in the material universe would be productive of little benefit. But in reality the mind passes from one of these topics of speculation to the other, without accurately distributing them into classes, or imagining that there is any difference in the certainty with which they are attended. Hence it appears that the most uninstructed peasant or artisan is practically a necessarian. The farmer calculates as securely upon the inclination of mankind to buy his corn when it is brought into the market, as upon the tendency of the seasons to ripen it. The labourer no more suspects that his employer will alter his mind and not pay him his daily wages, than he suspects that his tools will refuse to perform those functions today, in which they were yesterday employed with success* .
Another argument in favour of the doctrine of necessity, notBOOK IV. CHAP. V. The truth of this sentiment argued from the nature of volition less clear and irresistible than that from the consideration of cause and effect, will arise from any consistent explication that can be given of the nature of voluntary motion. The motions of the animal system distribute themselves into two great classes, voluntary and involuntary. Involuntary motion, whether it be conceived to take place independently of the mind, or to be the result of thought and perception, is so called, because the consequences of that motion, either in whole or in part, did not enter into the view of the mind when the motion commenced. Thus the cries of a new-born infant are not less involuntary than the circulation of the blood; it being impossible that the sounds first resulting from a certain agitation of the animal frame should be foreseen, since foresight is the fruit of experience.
From these observations we may deduce a rational and consistent account of the nature of volition. Voluntary motion is that which is accompanied with foresight, and flows from intention and design. Volition is that state of an intellectual being, in which, the mind being affected in a certain manner by the apprehension of an end to be accomplished, a certain motion of the organs and members of the animal frame is found to be produced.
Here then the advocates of intellectual liberty have a clear BOOK IV. CHAP. V. dilemma proposed to their choice. They must ascribe this freedom, this imperfect connexion of effects and causes, either to our voluntary or our involuntary motions. They have already made their determination. They are aware that to ascribe freedom to that which is involuntary, even if the assumption could be maintained, would be altogether foreign to the great subjects of moral, theological or political enquiry. Man would not be in any degree more of an agent or an accountable being, though it could be proved that all his involuntary motions sprung up in a fortuitous and capricious manner.
But on the other hand to ascribe freedom to our voluntary actions is an express contradiction in terms. No motion is voluntary any farther than it is accompanied with intention and design, and flows from the apprehension of an end to be accomplished. So far as it flows in any degree from another source, so far it is involuntary. The new-born infant foresees nothing, therefore all his motions are involuntary. A person arrived at maturity takes an extensive survey of the consequences of his actions, therefore he is eminently a voluntary and rational being. If any part of my conduct be destitute of all foresight of the effects to result, who is there that ascribes to it depravity and vice? Xerxes acted just as soberly as such a reasoner, when he caused his attendants to inflict a thousand lashes on the waves of the Hellespont.
The truth of the doctrine of necessity will be still more evident,BOOK IV. CHAP. V. Hypothesis of free will examined. if we consider the absurdity of the opposite hypothesis. One of its principal ingredients is self determination. Liberty in an imperfect and popular sense is ascribed to the motions ofSelf determination the animal system, when they result from the foresight and deliberation of the intellect, and not from external compulsion. It is in this sense that the word is commonly used in moral and political reasoning. Philosophical reasoners therefore, who have desired to vindicate the property of freedom, not only to our external motions, but to the acts of the mind, have been obliged to repeat this process. Our external actions are then said to be free, when they truly result from the determination of the mind. If our volitions, or internal acts be also free, they must in like manner result from the determination of the mind, or in other words, “the mind in adopting them” must be “self determined.” Now nothing can be more evident than that that in which the mind exercises its freedom, must be an act of the mind. Liberty therefore according to this hypothesis consists in this, that every choice we make has been chosen by us, and every act of the mind been preceded and produced by an act of the mind. This is so true, that in reality the ultimate act is not styled free from any quality of its own, but because the mind in adopting it was self determined, that is, because it was preceded by another act. The ultimate act resulted completely from the determination that was its precursor. It was itself necessary; and, if we would look for freedom, it must be in the preceding act. But in that BOOK IV. CHAP. V. preceding act also, if the mind were free, it was self determined, that is, this volition was chosen by a preceding volition, and by the same reasoning this also by another antecedent to itself. All the acts except the first were necessary, and followed each other as inevitably as the links of a chain do, when the first link is drawn forward. But then neither was this first act free, unless the mind in adopting it were self determined, that is, unless this act were chosen by a preceding act. Trace back the chain as far as you please, every act at which you arrive is necessary. That act, which gives the character of freedom to the whole, can never be discovered; and, if it could, in its own nature includes a contradiction.
Indifference Another idea which belongs to the hypothesis of self determination, is, that the mind is not necessarily inclined this way or that by the motives which are presented to it, by the clearness or obscurity with which they are apprehended, or by the temper and character which preceding habits may have generated; but that by its inherent activity it is equally capable of proceeding either way, and passes to its determination from a previous state of absolute indifference. Now what sort of activity is that which is equally inclined to all kinds of actions? Let us suppose a particle of matter endowed with an inherent propensity to motion. This propensity must either be to move in one particular direction, and then it must for ever move in that direction unless counteracted by some external impression; or it must have an equal tendency to all directions, and then the result mustBOOK IV. CHAP. V. be a state of perpetual rest.
The absurdity of this consequence is so evident, that the advocates of intellectual liberty have endeavoured to destroy its force by means of a distinction. “Motive,” it has been said, “is indeed the occasion, the sine qua non of volition, but it has no inherent power to compel volition. Its influence depends upon the free and unconstrained surrender of the mind. Between opposite motives and considerations the mind can choose as it pleases, and by its determination can convert the motive which is weak and insufficient in the comparison into the strongest.” But this hypothesis will be found exceedingly inadequate to the purpose for which it is produced. Motives must either have a necessary and irresistible influence, or they can have no influence at all.
For, first, it must be remembered, that the ground or reason of any event, of whatever nature it be, must be contained among the circumstances which precede that event. The mind is supposed to be in a state of previous indifference, and therefore cannot be, in itself considered, the source of the particular choice that is made. There is a motive on one side and a motive on the other: and between these lie the true ground and reason of preference. But, wherever there is tendency to preference, there may be degrees of tendency. If the degrees be BOOK IV. CHAP. V. equal, preference cannot follow: it is equivalent to the putting equal weights into the opposite scales of a balance. If one of them have a greater tendency to preference than the other, that which has the greatest tendency must ultimately prevail. When two things are balanced against each other, so much amount may be conceived to be struck off from each side as exists in the smaller sum, and the overplus that belongs to the greater is all that truly enters into the consideration.
Add to this, secondly, that, if motive have not a necessary influence, it is altogether superfluous. The mind cannot first choose to be influenced by a motive, and afterwards submit to its operation: for in that case the preference would belong wholly to this previous volition. The determination would in reality be complete in the first instance; and the motive, which came in afterwards, might be the pretext, but could not be the true source of the proceeding* .
The will not a distinct faculty Lastly, it may be observed upon the hypothesis of free will, that the whole system is built upon a distinction where there is no difference, to wit, a distinction between the intellectual and active powers of the mind. A mysterious philosophy taught men to suppose, that, when the understanding had perceived any object to be desirable, there was need of some distinct power to put the body in motion. But reason finds no groundBOOK IV. CHAP. V. for this supposition; nor is it possible to conceive, that, in the case of an intellectual faculty placed in an aptly organised body, preference can exist, together with a consciousness, gained from experience, of our power to obtain the object preferred, without a certain motion of the animal frame being the necessary result. We need only attend to the obvious meaning of the terms in order to perceive that the will is merely, as it has been happily termed, the last act of the understanding, one of the different cases of the association of ideas. What indeed is preference, but a perception of something that really inheres or is supposed to inhere in the objects themselves? It is the judgment, true or erroneous, which the mind makes respecting such things as are brought into comparison with each other. If this had been sufficiently attended to, the freedom of the will would never have been gravely maintained by philosophical writers, since no man ever imagined that we were free to feel or not to feel an impression made upon our organs, and to believe or not to believe a proposition demonstrated to our understanding.
It must be unnecessary to add any thing farther on this head,Free will disadvantageous to its possessor: unless it be a momentary recollection of the sort of benefit that freedom of the will would confer upon us, supposing it to be possible. Man being, as we have now found him to be, a simple substance, governed by the apprehensions of his understanding, nothing farther is requisite but the improvement of his BOOK IV. CHAP. V. reasoning faculty, to make him virtuous and happy. But, did he possess a faculty independent of the understanding, and capable of resisting from mere caprice the most powerful arguments, the best education and the most sedulous instruction might be of no use to him. This freedom we shall easily perceive to be his bane and his curse; and the only hope of lasting benefit to the species would be, by drawing closer the connexion between the external motions and the understanding, wholly to extirpate it. The virtuous man, in proportion to his improvement, will be under the constant influence of fixed and invariable principles; and such a being as we conceive God to be, can never in any one instance have exercised this liberty, that is, can never of no service to morality have acted in a foolish and tyrannical manner. Freedom of the will is absurdly represented as necessary to render the mind susceptible of moral principles; but in reality, so far as we act with liberty, so far as we are independent of motives, our conduct is as independent of morality as it is of reason, nor is it possible that we should deserve either praise or blame for a proceeding thus capricious and indisciplinable.
