For, in reference to this matter, there are two doctrines, which appear to represent different stages of civilization. According to the first doctrine, every event is single and isolated, and is merely considered as the result of a blind chance. This opinion, which is most natural to a perfectly ignorant people, would soon be weakened by that extension of experience which supplies a knowledge of those uniformities of succession and of co-existence that nature constantly presents. If, for example, wandering tribes, without the least tincture of civilization, lived entirely by hunting and fishing, they might well suppose that the appearance of their necessary food was the result of some accident which admitted of no explanation. The irregularity of the supply, and the apparent caprice with which it was sometimes abundant and sometimes scanty, would prevent them from suspecting anything like method in the arrangements of nature; nor could their minds even conceive the existence of those general principles which govern the order of events, and by a knowledge of which we are often able to predict their future course. But when such tribes advance into the agricultural state, they, for the first time, use a food of which not only the appearance, but the very existence, seems to be the result of their own act. What they sow, that likewise do they reap. The provision necessary for their wants is brought more immediately under their own control, and is more palpably the consequence of their own labour. They perceive a distinct plan, and a regular uniformity of sequence, in the relation which the seed they put into the ground bears to the corn when arrived at maturity. They are now able to look to the future, not indeed with certainty, but with a confidence infinitely greater than they could have felt in their former and more precarious pursuits.[3] Hence there arises a dim idea of the stability of events; and for the first time there begins to dawn upon the mind a faint conception of what at a later period are called the Laws of Nature. Every step in the great progress will make their view of this more clear. As their observations accumulate, and as their experience extends over a wider surface, they meet with uniformities that they had never suspected to exist, and the discovery of which weakens that doctrine of chance with which they had originally set out. Yet a little further, and a taste for abstract reasoning springs up; and then some among them generalize the observations that have been made, and despising the old popular opinion, believe that every event is linked to its antecedent by an inevitable connexion, that such antecedent is connected with a preceding fact; and that thus the whole world forms a necessary chain, in which indeed each man may play his part, but can by no means determine what that part shall be.
Thus it is that, in the ordinary march of society, an increasing perception of the regularity of nature destroys the doctrine of Chance, and replaces it by that of Necessary Connexion. And it is, I think, highly probable that out of these two doctrines of Chance and Necessity there have respectively arisen the subsequent dogmas of Free Will and Predestination. Nor is it difficult to understand the manner in which, in a more advanced state of society, this metamorphosis would occur. In every country, as soon as the accumulation of wealth has reached a certain point, the produce of each man's labour becomes more than sufficient for his own support: it is therefore no longer necessary that all should work; and there is formed a separate class, the members of which pass their lives for the most part in the pursuit of pleasure; a very few, however, in the acquisition and diffusion of knowledge. Among these last there are always found some who, neglecting external events, turn their attention to the study of their own minds;[4] and such men, when possessed of great abilities, become the founders of new philosophies and new religions, which often exercise immense influence over the people who receive them. But the authors of these systems are themselves affected by the character of the age in which they live. It is impossible for any man to escape the pressure of surrounding opinions; and what is called a new philosophy or a new religion is generally not so much a creation of fresh ideas, but rather a new direction given to ideas already current among contemporary thinkers.[5] Thus, in the case now before us, the doctrine of Chance in the external world corresponds to that of Free Will in the internal: while the other doctrine of Necessary Connexion is equally analogous to that of Predestination; the only difference being that the first is a development by the metaphysician, the second by the theologian. In the first instance, the metaphysician setting out with the doctrine of Chance, carries into the study of the mind this arbitrary and irresponsible principle, which in its new field becomes Free Will; an expression by which all difficulties seem to be removed, since perfect freedom, itself the cause of all actions, is caused by none, but, like the doctrine of Chance, is an ultimate fact admitting of no further explanation.[6] In the second instance, the theologian taking up the doctrine of Necessary Connexion recasts it into a religious shape; and his mind being already full of conceptions of order and of uniformity, he naturally ascribes such undeviating regularity to the prescience of Supreme Power; and thus to the magnificent notion of One God there is added the dogma that by Him all things have from the beginning been absolutely pre-determined and preordained.
These opposite doctrines of free will and predestination[7] do, no doubt, supply a safe and simple solution of the obscurities of our being; and as they are easily understood, they are so suited to the average capacity of the human mind, that even at the present day an immense majority of men are divided between them; and they have not only corrupted the sources of our knowledge, but have given rise to religious sects, whose mutual animosities have disturbed society, and too often embittered the relations of private life. Among the more advanced European thinkers there is, however, a growing opinion that both doctrines are wrong or, at all events, that we have no sufficient evidence of their truth. And as this is a matter of great moment, it is important, before we proceed further, to clear up as much of it as the difficulties inherent in these subjects will enable us to do.
Whatever doubts may be thrown on the account which I have given of the probable origin of the ideas of free will and predestination, there can, at all events, be no dispute as to the foundation on which those ideas are now actually based. The theory of predestination is founded on a theological hypothesis; that of free will on a metaphysical hypothesis. The advocates of the first proceed on a supposition for which, to say the least of it, they have as yet brought forward no good evidence. They require us to believe that the Author of Creation, whose beneficence they at the same time willingly allow, has, notwithstanding His supreme goodness, made an arbitrary distinction between the elect and the non-elect; that He has from all eternity doomed to perdition millions of creatures yet unborn, and whom His act alone can call into existence: and that He has done this, not in virtue of any principle of justice, but by a mere stretch of despotic power.[8] This doctrine owes its authority among Protestants to the dark though powerful mind of Calvin; but in the early Church it was first systematically methodized by Augustin, who appears to have borrowed it from the Manicheans.[9] At all events, and putting aside its incompatibility with other notions which are supposed to be fundamental,[10] it must, in a scientific investigation, be regarded as a barren hypothesis, because, being beyond the province of our knowledge, we have no means of ascertaining either its truth or its falsehood.
The other doctrine, which has long been celebrated under the name of Free Will, is connected with Arminianism; but it in reality rests on the metaphysical dogma of the supremacy of human consciousness. Every man, it is alleged, feels and knows that he is a free agent: nor can any subtleties of argument do away with our consciousness of possessing a free will.[11] Now the existence of this supreme jurisdiction, which is thus to set at defiance all the ordinary methods of reasoning, involves two assumptions: of which the first, though possibly true, has never been proved; and the other is unquestionably false. These assumptions are, that there is an independent faculty called consciousness, and that the dictates of that faculty are infallible. But, in the first place, it is by no means certain that consciousness is a faculty; and some of the ablest thinkers have been of opinion that it is merely a state or condition of the mind.[12] Should this turn out to be the case, the argument falls to the ground; since, even if we admit that all the faculties of the mind, when completely exercised, are equally accurate, no one will make the same claim for every condition into which the mind itself may be casually thrown. However, waiving this objection, we may, in the second place, reply, that even if consciousness is a faculty, we have the testimony of all history to prove its extreme fallibility.[13] All the great stages through which, in the progress of civilization, the human race has successively passed, have been characterized by certain mental peculiarities or convictions, which have left their impress upon the religion, the philosophy, and the morals of the age. Each of these convictions has been to one period a matter of faith, to another a matter for derision;[14] and each of them has, in its own epoch, been as intimately bound up with the minds of men, and become as much a part of their consciousness, as is that opinion which we now term freedom of the will. Yet it is impossible that all these products of consciousness can be true, because many of them contradict each other. Unless, therefore, in different ages there are different standards of truth, it is clear that the testimony of a man's consciousness is no proof of an opinion being true; for if it were so, then two propositions diametrically opposed to each other might both be equally accurate. Besides this, another view may be drawn from the common operations of ordinary life. Are we not in certain circumstances conscious of the existence of spectres and phantoms; and yet is it not generally admitted that such beings have no existence at all? Should it be attempted to refute this argument by saying that such consciousness is apparent and not real, then I ask, What is it that judges between the consciousness which is genuine and that which is spurious?[15] If this boasted faculty deceives us in some things, what security have we that it will not deceive us in others? If there is no security, the faculty is not trustworthy. If there is a security, then, whatever it may be, its existence shows the necessity for some authority to which consciousness is subordinate, and thus does away with that doctrine of the supremacy of consciousness, on which the advocates of free will are compelled to construct the whole of their theory. Indeed, the uncertainty as to the existence of consciousness as an independent faculty, and the manner in which that faculty, if it exists, has contradicted its own suggestions, are two of the many reasons which have long since convinced me that metaphysics will never be raised to a science by the ordinary method of observing individual minds; but that its study can only be successfully prosecuted by the deductive application of laws which must be discovered historically, that is to say, which must be evolved by an examination of the whole of those vast phenomena which the long course of human affairs presents to our view.
Fortunately, however, for the object of this work, the believer in the possibility of a science of history is not called upon to hold either the doctrine of predestined events, or that of freedom of the will;[16] and the only positions which, in this stage of the inquiry, I shall expect him to concede are the following: That when we perform an action, we perform it in consequence of some motive or motives; that those motives are the results of some antecedents; and that, therefore, if we were acquainted with the whole of the antecedents, and with all the laws of their movements, we could with unerring certainty predict the whole of their immediate results. This, unless I am greatly mistaken, is the view which must be held by every man whose mind is unbiased by system, and who forms his opinions according to the evidence actually before him.[17] If, for example, I am intimately acquainted with the character of any person, I can frequently tell how he will act under some given circumstances. Should I fail in this prediction, I must ascribe my error not to the arbitrary and capricious freedom of his will, nor to any supernatural pre-arrangement, for of neither of these things have we the slightest proof; but I must be content to suppose either that I had been misinformed as to some of the circumstances in which he was placed, or else that I had not sufficiently studied the ordinary operations of his mind. If, however, I were capable of correct reasoning, and if, at the same time, I had a complete knowledge both of his disposition and of all the events by which he was surrounded, I should be able to foresee the line of conduct which, in consequence of those events, he would adopt.[18]
Rejecting, then, the metaphysical dogma of free will, and the theological dogma of predestined events,[19] we are driven to the conclusion that the actions of men, being determined solely by their antecedents, must have a character of uniformity, that is to say, must, under precisely the same circumstances, always issue in precisely the same results. And as all antecedents are either in the mind or out of it, we clearly see that all the variations in the results, in other words, all the changes of which history is full, all the vicissitudes of the human race, their progress or their decay, their happiness or their misery, must be the fruit of a double action; an action of external phenomena upon the mind, and another action of the mind upon the phenomena.
These are the materials out of which a philosophic history can alone be constructed. On the one hand, we have the human mind obeying the laws of its own existence, and, when uncontrolled by external agents, developing itself according to the conditions of its organization. On the other hand, we have what is called Nature, obeying likewise its laws; but incessantly coming into contact with the minds of men, exciting their passions, stimulating their intellect, and therefore giving to their actions a direction which they would not have taken without such disturbance. Thus we have man modifying nature, and nature modifying man; while out of this reciprocal modification all events must necessarily spring.
The problem immediately before us, is to ascertain the method of discovering the laws of this double modification: and this, as we shall presently see, leads us into a preliminary inquiry as to which of the two modifications is the more important; that is to say, whether the thoughts and desires of men are more influenced by physical phenomena, or whether the physical phenomena are more influenced by them. For it is evident that whichever class is the more active, should if possible be studied before the other; and this, partly because its results will be more prominent, and therefore more easy to observe; and partly because by first generalizing the laws of the greater power we shall leave a smaller residue of unexplained facts than if we had begun by generalizing the laws of the lesser power. But, before entering into this examination, it will be convenient to state some of the most decisive proofs we now possess of the regularity with which mental phenomena succeed each other. By this means the preceding views will be considerably strengthened; and we shall, at the same time, be able to see what those resources are which have been already employed in elucidating this great subject.
That the results actually effected are extremely valuable is evident, not only from the wide surface which the generalizations cover, but also from the extraordinary precautions with which they have been made. For while most moral inquiries have depended on some theological or metaphysical hypothesis, the investigations to which I allude are exclusively inductive; they are based on collections of almost innumerable facts, extending over many countries, thrown into the clearest of all forms, the form of arithmetical tables; and finally, they have been put together by men who, being for the most part mere government officials,[20] had no particular theory to maintain, and no interest in distorting the truth of the reports they were directed to make.
