The most comprehensive inferences respecting the actions of men, which are admitted by all parties as incontestable truths, are derived from this or from analogous sources; they rest on statistical evidence, and are expressed in mathematical language. And whoever is aware of how much has been discovered by this single method, must not only recognize the uniformity with which mental phenomena succeed each other, but must, I think, feel sanguine that still more important discoveries will be made, so soon as there are brought into play those other powerful resources which even the present state of knowledge will abundantly supply. Without, however, anticipating future inquiries, we are, for the moment, only concerned with those proofs of the existence of a uniformity in human affairs which statisticians have been the first to bring forward.
The actions of men are by an easy and obvious division separated into two classes, the virtuous and the vicious; and as these classes are correlative, and when put together compose the total of our moral conduct, it follows that whatever increases the one, will in a relative point of view diminish the other; so that if we can in any period detect a uniformity and a method in the vices of a people, there must be a corresponding regularity in their virtues; or if we could prove a regularity in their virtues, we should necessarily infer an equal regularity in their vices; the two sets of actions being, according to the terms of the division, merely supplementary to each other.[21] Or, to express this proposition in another way, it is evident that if it can be demonstrated that the bad actions of men vary in obedience to the changes in the surrounding society, we shall be obliged to infer that their good actions, which are, as it were, the residue of their bad ones, vary in the same manner; and we shall be forced to the further conclusion, that such variations are the result of large and general causes, which, working upon the aggregate of society, must produce certain consequences, without regard to the volition of those particular men of whom the society is composed.
Such is the regularity we expect to find, if the actions of men are governed by the state of the society in which they occur; while, on the other hand, if we can find no such regularity, we may believe that their actions depend on some capricious and personal principle peculiar to each man, as free will or the like. It becomes, therefore, in the highest degree important to ascertain whether or not there exists a regularity in the entire moral conduct of a given society; and this is precisely one of those questions for the decision of which statistics supply us with materials of immense value.
For the main object of legislation being to protect the innocent against the guilty, it naturally followed that European governments, so soon as they became aware of the importance of statistics, should begin to collect evidence respecting the crimes they were expected to punish. This evidence has gone on accumulating, until it now forms of itself a large body of literature, containing, with the commentaries connected with it, an immense array of facts, so carefully compiled, and so well and clearly digested, that more may be learned from it respecting the moral nature of Man than can be gathered from all the accumulated experience of preceding ages.[22] But as it will be impossible in this Introduction to give anything like a complete statement of those inferences which, in the actual state of statistics, we are authorized to draw, I shall content myself with examining two or three of the most important, and pointing out the connexion between them.
Of all offences, it might well be supposed that the crime of murder is one of the most arbitrary and irregular. For when we consider that this, though generally the crowning act of a long career of vice, is often the immediate result of what seems a sudden impulse; that when premeditated, its committal, even with the least chance of impunity, requires a rare combination of favourable circumstances for which the criminal will frequently wait; that he has thus to bide his time, and look for opportunities he cannot control; that when the time has come his heart may fail him; that the question whether or not he shall commit the crime may depend on a balance of conflicting motives, such as fear of the law, a dread of the penalties held out by religion, the prickings of his own conscience, the apprehension of future remorse, the love of gain, jealousy, revenge, desperation;—when we put all these things together, there arises such a complication of causes, that we might reasonably despair of detecting any order or method in the result of those subtle and shifting agencies by which murder is either caused or prevented. But now, how stands the fact? The fact is, that murder is committed with as much regularity, and bears as uniform a relation to certain known circumstances, as do the movements of the tides, and the rotations of the seasons. M. Quetelet, who has spent his life in collecting and methodizing the statistics of different countries, states, as the result of his laborious researches, that ‘in everything which concerns crime, the same numbers re-occur with a constancy which cannot be mistaken; and that this is the case even with those crimes which seem quite independent of human foresight, such, for instance, as murders, which are generally committed after quarrels arising from circumstances apparently casual. Nevertheless, we know from experience that every year there not only take place nearly the same number of murders, but that even the instruments by which they are committed are employed in the same proportion.’[23] This was the language used in 1835 by confessedly the first statistician in Europe, and every subsequent investigation has confirmed its accuracy. For later inquiries have ascertained the extraordinary fact that the uniform reproduction of crime is more clearly marked, and more capable of being predicted, than are the physical laws connected with the disease and destruction of our bodies. Thus, for instance, the number of persons accused of crime in France between 1826 and 1844 was, by a singular coincidence, about equal to the male deaths which took place in Paris during the same period, the difference being that the fluctuations in the amount of crime were actually smaller than the fluctuations in the mortality; while a similar regularity was observed in each separate offence, all of which obeyed the same law of uniform and periodical repetition.[24]
This, indeed, will appear strange to those who believe that human actions depend more upon the peculiarities of each individual than on the general state of society. But another circumstance remains behind still more striking. Among public and registered crimes there is none which seems so completely dependent on the individual as suicide. Attempts to murder or to rob may be, and constantly are, successfully resisted; baffled sometimes by the party attacked, sometimes by the officers of justice. But an attempt to commit suicide is much less liable to interruption. The man who is determined to kill himself is not prevented at the last moment by the struggles of an enemy; and, as he can easily guard against the interference of the civil power,[25] his act becomes as it were isolated; it is cut off from foreign disturbances, and seems more clearly the product of his own volition than any other offence could possibly be. We may also add that, unlike crimes in general, it is rarely caused by the instigation of confederates; so that men, not being goaded into it by their companions, are uninfluenced by one great class of external associations which might hamper what is termed the freedom of their will. It may, therefore, very naturally be thought impracticable to refer suicide to general principles, or to detect anything like regularity in an offence which is so eccentric, so solitary, so impossible to control by legislation, and which the most vigilant police can do nothing to diminish. There is also another obstacle that impedes our view: this is, that even the best evidence respecting suicide must always be very imperfect. In cases of drowning, for example, deaths are liable to be returned as suicides which are accidental; while, on the other hand, some are called accidental which are voluntary.[26] Thus it is, that self-murder seems to be not only capricious and uncontrollable, but also very obscure in regard to proof; so that on all these grounds it might be reasonable to despair of ever tracing it to those general causes by which it is produced.
These being the peculiarities of this singular crime, it is surely an astonishing fact, that all the evidence we possess respecting it points to one great conclusion, and can leave no doubt on our minds that suicide is merely the product of the general condition of society, and that the individual felon only carries into effect what is a necessary consequence of preceding circumstances.[27] In a given state of society, a certain number of persons must put an end to their own life. This is the general law; and the special question as to who shall commit the crime depends, of course, upon special laws; which, however, in their total action, must obey the large social law to which they are all subordinate. And the power of the larger law is so irresistible, that neither the love of life nor the fear of another world can avail anything towards even checking its operation. The causes of this remarkable regularity I shall hereafter examine; but the existence of the regularity is familiar to whoever is conversant with moral statistics. In the different countries for which we have returns, we find year by year the same proportion of persons putting an end to their own existence; so that, after making allowance for the impossibility of collecting complete evidence, we are able to predict, within a very small limit of error, the number of voluntary deaths for each ensuing period; supposing, of course, that the social circumstances do not undergo any marked change. Even in London, notwithstanding the vicissitudes incidental to the largest and most luxurious capital in the world, we find a regularity greater than could be expected by the most sanguine believer in social laws; since political excitement, mercantile excitement, and the misery produced by the dearness of food, are all causes of suicide, and are all constantly varying.[28] Nevertheless, in this vast metropolis, about 240 persons every year make away with themselves; the annual suicides oscillating, from the pressure of temporary causes, between 266, the highest, and 213, the lowest. In 1846, which was the great year of excitement caused by the railway panic, the suicides in London were 266; in 1847 began a slight improvement, and they fell to 256; in 1848 they were 247; in 1849 they were 213; and in 1850 they were 229.[29]
Such is some, and only some, of the evidence we now possess respecting the regularity with which, in the same state of society, the same crimes are necessarily reproduced. To appreciate the full force of this evidence, we must remember that it is not an arbitrary selection of particular facts, but that it is generalized from an exhaustive statement of criminal statistics, consisting of many millions of observations, extending over countries in different grades of civilization, with different laws, different opinions, different morals, different habits. If we add to this, that these statistics have been collected by persons specially employed for that purpose, with every means of arriving at the truth, and with no interest to deceive, it surely must be admitted that the existence of crime according to a fixed and uniform scheme, is a fact more clearly attested than any other in the moral history of man. We have here parallel chains of evidence formed with extreme care, under the most different circumstances, and all pointing in the same direction; all of them forcing us to the conclusion, that the offences of men are the result not so much of the vices of the individual offender as of the state of society into which that individual is thrown.[30] This is an inference resting on broad and tangible proofs accessible to all the world; and as such cannot be overturned, or even impeached, by any of those hypotheses with which metaphysicians and theologians have hitherto perplexed the study of past events.
Those readers who are acquainted with the manner in which in the physical world the operations of the laws of nature are constantly disturbed, will expect to find in the moral world disturbances equally active. Such aberrations proceed, in both instances, from minor laws, which at particular points meet the larger laws, and thus alter their normal action. Of this, the science of mechanics affords a good example in the instance of that beautiful theory called the parallelogram of forces; according to which the forces are to each other in the same proportion as is the diagonal of their respective parallelograms.[31] This is a law pregnant with great results; it is connected with those important mechanical resources, the composition and resolution of forces; and no one acquainted with the evidence on which it stands, ever thought of questioning its truth. But the moment we avail ourselves of it for practical purposes, we find that in its action it is warped by other laws, such as those concerning the friction of air, and the different density of the bodies on which we operate, arising from their chemical composition, or, as some suppose, from their atomic arrangement. Perturbations being thus let in, the pure and simple action of the mechanical law disappears. Still, and although the results of the law are incessantly disturbed, the law itself remains intact.[32] Just in the same way, the great social law, that the moral actions of men are the product not of their volition, but of their antecedents, is itself liable to disturbances which trouble its operation without affecting its truth. And this is quite sufficient to explain those slight variations which we find from year to year in the total amount of crime produced by the same country. Indeed, looking at the fact that the moral world is far more abundant in materials than the physical world, the only ground for astonishment is that these variations should not be greater; and from the circumstance that the discrepancies are so trifling, we may form some idea of the prodigious energy of those vast social laws, which, though constantly interrupted, seem to triumph over every obstacle, and which, when examined by the aid of large numbers, scarcely undergo any sensible perturbation.[33]
Nor is it merely the crimes of men which are marked by this uniformity of sequence. Even the number of marriages annually contracted, is determined, not by the temper and wishes of individuals, but by large general facts, over which individuals can exercise no authority. It is now known that marriages bear a fixed and definite relation to the price of corn;[34] and in England the experience of a century has proved that, instead of having any connexion with personal feelings, they are simply regulated by the average earnings of the great mass of the people:[35] so that this immense social and religious institution is not only swayed, but is completely controlled, by the price of food and by the rate of wages. In other cases, uniformity has been detected, though the causes of the uniformity are still unknown. Thus, to give a curious instance, we are now able to prove that even the aberrations of memory are marked by this general character of necessary and invariable order. The post-offices of London and of Paris have latterly published returns of the number of letters which the writers, through forgetfulness, omitted to direct; and, making allowance for the difference of circumstances, the returns are year after year copies of each other. Year after year the same proportion of letter-writers forget this simple act; so that for each successive period we can actually foretell the number of persons whose memory will fail them in regard to this trifling and, as it might appear, accidental occurrence.[36]
