An allusion so very slender to so vast a subject as sociology would be a waste of words, but for the conviction, that through sociology is the way to the great field of Ethics. This is to reverse the traditional arrangement--ethics, politics, or government--followed even by Bentham.

The lights of ethics are, in the first instance, psychological; its discussions presuppose a number of definitions and distinctions that are pure psychology. But before these have to be adduced, the subject has to be set forth as a problem of sociology. "How is the King's government to be carried on?" "How is society to be held together?" is the first consideration; and the sociologist--as const.i.tution-builder, administrator, judge--is the person to grapple with the problem. It is with him that law, obligation, right, command, obedience, sanction, have their origin and their explanation. Ethics is an important supplement to social or political law. But it is still a department of law. In any other view it is a maze, a mystery, a hopeless embroilment.

That ethics is involved in society is of course admitted; what is not admitted is, that ethical terms should be settled under the social science in the first place. I may refer to the leading term "law," whose meaning in sociology is remarkably clear; in ethics remarkably the reverse. The confusion deepens when the moral faculty is brought forward. In the eye of the sociologist, nothing could be simpler than the conception of that part of our nature that is appealed to for securing obedience. He a.s.sumes a certain effort of the intelligence for understanding the signification of a command or a law; and, for the motive part, he counts upon nothing but volition in its most ordinary form--the avoidance of a pain. Intelligence and Will, in their usual and recognised workings, are all that are required for social obedience; law is conceived and framed exactly to suit the every-day and every-hour manifestations of these powers. The lawgiver does not speak of an obedience-faculty, nor even of a social-faculty. If there were in the mind a power unique and apart, having nothing in common with our usual intelligence, and nothing in common with our usual will or volition, that power ought to be expressed in terms that exclude the smallest partic.i.p.ation of both knowledge and will; it ought to have a form special to itself, and not the form:--"Do this, and ye shall be made to suffer".

I am quite aware that there are elements in ethics not included in the problem of social obedience; what I contend for is, that the ground should be cleared by marking out the two provinces, as is actually done by a very small number of theorists, of whom John Austin is about the best example.

The ethical philosopher, from not building on a foregone sociology, is obliged to extemporize, in a paragraph, the social system; just as the physical philosopher would, if he had no regularly constructed mathematics to fall back upon, but had to stop every now and then to enunciate a mathematical theorem.

The question of the ethical end should first appear as the question of the sociological end. For what purpose or purposes is society maintained? All the ethical difficulties are here met by antic.i.p.ation, and in a form much better adapted to their solution. It is from the point of view of the social ruler, that you learn reserve, moderation, and sobriety in your aims; you learn to think that something much less than the Utopias--universal happiness and universal virtue--should be propounded; you find that a definite and limited province can be a.s.signed, separating what the social power is able to do, must do, and can advantageously do, from what it is unable to do, need not do, and cannot with advantage do; and this or a similar demarcation is reproducible in ethics.

[PRECEPTS OF ETHICS MAINLY SOCIAL.]

The precepts of ethics are mainly the precepts of social authority; at all events the social precepts and their sanctions have the priority in scientific method. Some of the highest virtues are sociological; patriotic self-sacrifice is one of the conditions of social preservation. The inculcation of this and of many other virtues would not appear in ethics at all, or only in a supplementary treatment, if social science took its proper sphere, and fully occupied that sphere.

Once more. The great problem of moral control, which I would remove entirely from a science of education, would be first dealt with in Sociology. It there appears in the form of the choice and gradation of punishments, in prison discipline, and in the reformation of criminals,--all which have been made the subject of enlightened, not to say scientific, treatment. It is in the best experience in those subjects that I would begin to seek for lights on the comprehensive question. I would next go to diplomacy for the arts of delicate address in reconciling opposing interests; after which I would look to the management of parties and conflicting interests in the State. I would farther inquire how armies are disciplined, and subordination combined with the enthusiasm that leads to n.o.ble deeds.

There is an abundant field for the application of pure psychology to ethics, when it takes its own proper ground. The exact psychological character of disinterested impulse needs to be a.s.signed; and, if that impulse can be fully referred to the sympathetic or social instincts and habits, the supposed moral faculty is finally eviscerated of its contents for all ethical purposes.

So far I have exemplified what seems to me real or genuine aims and applications of metaphysical study. I now proceed to the objects that are more or less fact.i.tious. We are here on delicate ground, and run the risk of discrediting our pursuit, as regards the very things that in the eyes of many people make its value.

First, then, as psychology involves all our sensibilities, pleasures, affections, aspirations, capacities, it is thought on that ground to have a special n.o.bility and greatness, and a special power of evoking in the student the feelings themselves. The mathematician, dealing with conic sections, spirals, and differential equations, is in danger of being ultimately resolved into a function or a co-efficient; the metaphysician, by investigating conscience, must become conscientious; driving fat oxen is the way to grow fat.

[MAN'S RELATIONS TO THE INFINITE.]

But to pa.s.s to a far graver application. It has usually been supposed that metaphysical theory is more especially akin to the speculation that mounts to the supernatural and the transcendental world. "Man's relations to the infinite" is a frequent phrase in the mouth of the metaphysician. Metaphysics is supposed to be "philosophy" by way of eminence; and philosophy in the large sense has not merely to satisfy the curiosity of the human mind, it has to provide scope for its emotions and aspirations; in fact, to play the part of theology. In times when the prevailing orthodox beliefs are shaken, some scheme of philosophy is brought forward to take their place. If I understand aright the drift of the German metaphysical systems for a century back, they all more or less propose to themselves to supply the same spiritual wants as religion supplies. In our own country, such of us as are not under German influence put the matter differently; but we still consider that we have something to say on the "highest questions". We are apt to believe that on us more than on any other cla.s.s of thinkers, does it depend whether the prevailing theology shall be upheld, impugned, or transformed. The chief weapons of the defenders of the faith are forged in the schools of metaphysics. Locke and Butler, Reid, Stewart and Brown are theological authorities. And when theology is attacked, its metaphysical b.u.t.tresses have to be a.s.sailed as the very first thing. If these are declared unsound, either it must fall, or it must change its front. It is Natural Theology, more particularly, that is thus allied to metaphysics; yet, not exclusively; for the defence of Revelation by miracles involves at the outset a point of logic.

Now I do not mean to say, that this is a purely fact.i.tious and ill-grounded employment of the metaphysical sciences. I fully admit that the later defences of theology, as well as the attacks, have been furnished from psychology, logic, ethics, and ontology. The earliest beliefs in religion, the greatest and strongest convictions, had little to do with any of these departments of speculation. But when simple traditionary faith gave place to the questionings of the reason, the basis of religion was transferred to the reason-built sciences; and metaphysics came in for a large share in the decision.

[METAPHYSICS AND THEOLOGY.]

What I maintain is, that there is something fact.i.tious in the degree of prominence given to metaphysics in this great enterprise; that its pretentions are excessive, its importance over-stated; and when most employed for such a purpose, it is least to be trusted. Theological polemic is only in part conducted through science; and physical science shares equally with moral. The most serious shocks to the traditional orthodoxy have come from the physical sciences. The argument from Design has no doubt a metaphysical or logical element--the estimate of the degree of a.n.a.logy between the universe and a piece of human workmanship; but the argument itself needs a scientific survey of the entire phenomena of nature, both matter and mind. Our Bridgewater Treatises proceeded upon this view; they embraced the consideration of the whole circle of the sciences, as bearing on the theological argument. The scheme was so far just and to the purpose; the obvious drawback to the value of the Treatises lay in their being special pleadings, backed by a fee of a thousand pounds to each writer for maintaining one side. If a similar fee had been given to nine equally able writers to represent the other side, the argument from design would have been far more satisfactorily sifted than by the exclusively metaphysical criticism of Kant.

When theology is supported exclusively by such doctrines as--an independent and immaterial soul, a special moral faculty, and what is called free-will,--the metaphysician is a person of importance in the contest; he is powerful either to uphold or to subvert the fabric. But, if these were ever to const.i.tute the chief stronghold of the faith, its tenure would not be very secure. It is only a metaphysician, however, that believes or disbelieves in metaphysical grounds alone; such a man as Cousin, no doubt, rests his whole spiritual philosophy on this foundation. But the great ma.s.s will either adhere to religion in spite of metaphysical difficulties, or else abandon it notwithstanding its metaphysical evidences. An eminent man now departed said in my hearing, that he was a believer in Christianity until he became acquainted with geology, when, finding the first chapter of Genesis at variance with geological doctrines, he applied to the Bible the rule _falsus in uno, falsus in omnibus,_ and thenceforth abandoned his old belief. I never heard of any one that was so worked upon by a purely metaphysical argument.

The aspect of theological doctrine that has come most to the front of late is the question of the Divine goodness, as shown in the plan of the universe. Speculations are divided between optimism and pessimism. How shall we decide between these extremes, or, if repudiating both, how shall we fix the mean? Is a metaphysician more especially qualified to find out the truth? I hardly think so. I believe he could contribute, with others, to such a solution as may be possible. He has, we shall suppose, surveyed closely the compa.s.s of the human sensibilities, and is able to a.s.sign, with more than common precision, what things operate on them favourably or unfavourably. So far good. Then, as a logician, he is more expert at detecting bad inferences in regard to the form of reasoning; but whether certain allegations of fact are well or ill founded, he may not be able to say, at least out of his own department.

If a mixed commission of ten were nominated to adjudicate upon this vast problem, metaphysics might claim to be represented by two.

[FILLING THE THEOLOGICAL VOID.]

Least of all, do I understand the claims made in behalf of this department to supply the spiritual void in case the old theology is no longer accredited. When one looks closely at the stream and tendency of thought, one sees a growing alliance and kinship between religion and poetry or art. There is, as we know, a dogmatic, precise, severe, logical side of theology, by which creeds are constructed, religious tests imposed, and belief made a matter of legal compulsion. There is also a sentimental, ideal, imaginative side that resists definition, that refuses dogmatic prescription, and seeks only to satisfy spiritual needs and emotions. Metaphysics may no doubt take a part in the dogmatic or doctrinal treatment, but it must qualify itself by biblical study, and become altogether theology. In the other aspect, metaphysics, as I conceive it, is unavailing; the poet is the proper medium for keeping up the emotional side, under all transformations of doctrinal belief. But as conceived by others, metaphysics is philosophy and poetry in one, to which I can never agree. The combination of the two, as. .h.i.therto exhibited, has been made at the expense of both. The leading terms of philosophy--reason, spirit, soul, the ideal, the infinite, the absolute, phenomenal truth, being, consciousness--are lubricated with emotion, and thrown together in ways that defy the understanding. The unintelligible, which ought to be the shame of philosophy, is made its glory.

These remarks prepare for the conclusion that I arrive at as to the scope of metaphysics with reference to the higher questions. That it has bearings upon these questions I allow; and those bearings are legitimately within the range of metaphysical debates. But I make a wide distinction between metaphysical discussion and theological discussion; and do not consider that they can be combined to advantage. In the great lat.i.tude of free inquiry in the present day, theology is freely canva.s.sed, and societies might be properly devoted to that express object; but I cannot see any benefit that would arise by a philosophical society undertaking, in addition to its own province, to raise the questions belonging to theology. I am well aware that there is one society of very distinguished persons in the metropolis, calling itself metaphysical, that freely ventures upon the perilous seas of theological debate.[14] No doubt good comes from any exercise of the liberty of discussion, so long restrained in this region; yet, I can hardly suppose that purely metaphysical, studies can thrive in such a connection. Many of the members must think far more of the theological issues than of the cultivation of mental and logical science; and a purely metaphysical debate can seldom be pursued with profit under these conditions.

[POLEMICS IN GREECE.]

I now pa.s.s to the POLEMICAL handling of the metaphysical subjects. We owe to the Greeks the study of philosophy through methodised debate; and the state of scientific knowledge in the age of the early Athenian schools was favourable to that mode of treatment. The conversations of Socrates, the Dialogues of Plato, and the Topics of Aristotle, are the monuments of Greek contentiousness, turned to account as a great refinement in social intercourse, as a stimulus to individual thought, and a means of advancing at least the speculative departments of knowledge. Grote, both in his "Plato," and in his "Aristotle," while copiously ill.u.s.trating all these consequences, has laid extraordinary stress on still another aspect of the polemic of Socrates and Plato, the aspect of _free-thought_, as against venerated tradition and the received commonplaces of society. The a.s.sertion of the right of private judgment in matters of doctrine and belief, was, according to Grote, the greatest of all the fruits of the systematised negation begun by Zeno, and carried out in the "Search Dialogues" of Plato. In the "Exposition Dialogues" it is wanting; and in the "Topica," where Eristic is reduced to method and system by one of Aristotle's greatest logical achievements, the freethinker's wings are very much clipt; the execution of Socrates probably had to answer for that. It is to the Platonic dialogues that we look for the full grandeur of Grecian debate in all its phases. The Plato of Grote is the apotheosis of Negation; it is not a philosophy so much as an epic; the theme--"The n.o.ble Wrath of the Greek Dissenter".

At all times, there is much that has to be achieved by solitary thinking. Some definite shape must be given to our thoughts before we can submit them to the operation of other minds; the greater the originality, the longer must be the process of solitary elaboration.

The "Principia" was composed from first to last by recluse meditation; probably the attempt to discuss or debate any parts of it would have only fretted and paralysed the author's invention. Indeed, after an enormous strain of the constructive intellect, a man may be in no humour to have his work carped at, even to improve it. In the region of fact, in observation and experiment, there must be a ma.s.s of individual and una.s.sisted exertion. The use of allies in this region is to check and confirm the accuracy of the first observer.

Again, an inquirer, by dint of prolonged familiarity with a subject, may be his own best critic; he may be better able to detect flaws than any one he could call in. This is another way of stating the superiority of a particular individual over all others in the same walk. Such a monarchical position as removes a man alike from the rivalry and from the sympathy of his fellows, is the exception; mutual criticism and mutual encouragement are the rule. The social stimulants are of avail in knowledge and in truth as well as everything else.

A comparison of the state of speculation in the golden age of debate, with the state of the sciences in the present day, both metaphysical and physical, shows us clearly enough, what are the fields where polemic is most profitable. I set aside the struggles of politics and theology, and look to the scientific form of knowledge, which is, after all, the type of our highest certainty everywhere. Now, undoubtedly, it is in cla.s.sifying, generalising, defining, and in the so-called logical processes--induction and deduction--that a man can be least left to himself. Until many men have gone over the same field of facts, a cla.s.sification, a definition, or an induction, cannot be held as safe and sound. In modern science, there are numerous matters that have pa.s.sed through the fiery furnace of iterated criticism, seven times purified; but there are, attaching to every science, a number of things still in the furnace. Most of all does this apply to the metaphysical or subject sciences, where, according to the popular belief, nothing has yet pa.s.sed finally out of the fiery trial. In psychology, in logic, in eudaemonics, in sociology, in ethics, the facts are nearly all around our feet; the question is how to cla.s.sify, define, generalise, express them. This was the situation of Zeno, Socrates, and Plato, for which they invoked the militant ardour of the mind. Man, they saw, is a fighting being; if fighting will do a thing, he will do it well.

[MOST USEFUL CLa.s.sES OF DEBATES.]

In conformity with this view, the foremost cla.s.s of debates, and certainly not the least profitable, are such as discuss the meanings of important terms. The genius of Socrates perceived that this was the beginning of all valid knowledge, and, in seeing this, laid the foundation of reasoned truth. I need not repeat the leading terms of metaphysical philosophy; but you can at once understand the form of proceeding by such an instance as "consciousness," debated so as to bring out the question whether, as Hamilton supposed, it is necessarily grounded on knowledge.

Next to the leading terms are the broader and more fundamental generalities: for example, the law of relativity; the laws of memory and its conditions, such as the intensity of the present consciousness; Hamilton's inverse relationship of sensation and perception. These are a few psychological instances. The value of a debate on any of these questions depends entirely upon its resolving itself into an inductive survey of the facts, and such surveys are never without fruit.

A debating society that includes logic in its sphere should cultivate the methods of debate; setting an example to other societies and to mankind in general. The "Topica" of Aristotle shows an immensity of power expended on this object, doubtless without corresponding results.

Nevertheless the attempt, if resumed at the present day, with our clearer and wider views of logical method, would not be barren. This is too little thought of by us; and we may say that polemic, as an art, is still immature. The best examples of procedure are to be found in the Law Courts, some of whose methods might be borrowed in other debates.

For one thing, I think that each of the two leaders should provide the members beforehand with a synopsis of the leading arguments or positions to be set forth in the debate. This, I believe, should be insisted on everywhere, not even excepting the debates of Parliament.

It is the custom of debating societies to alternate the Debate and the Essay: a very important distinction, as it seems to me; and I will endeavour to indicate how it should be maintained. Frequently there is no substantial distinction observed; an essay is simply the opening of a debate, and a debate the criticism of an essay. I should like to see the two carried out each on its own principle, as I shall now endeavour to explain.

[THE DEBATE: A FIGHT FOR MASTERY.]

The Debate is _the fight for mastery_ as between two sides. The combatants strain their powers to say everything that can be said so as to shake the case of their opponents. The debate is a field-day, a challenge to a trial of strength. Now, while I admit that the intellectual powers may be quickened to unusual perspicacity under the sound of the trumpet and the shock of arms, I also see in the operation many perils and shortcomings, when the subject of contest is truth. In a heated controversy, only the more glaring and prominent facts, considerations, doctrines, distinctions, can obtain a footing. Now truth is the still small voice; it subsists often upon delicate differences, un.o.btrusive instances, fine calculations. Whether or not man is a wholly selfish being, may be submitted to a contentious debate, because the facts and appearances on both sides are broad and palpable; but whether all our actions are, in the last resort or final a.n.a.lysis, self-regarding, is almost too delicate for debate. Chalmers upholds, as a thesis, the intrinsic misery of the vicious affections: there could not be a finer topic of pure debate.

My conception of the Essay, on the other hand, is that it should represent _amicable co-operation_, with an eye to the truth. By it you should rise from the lower or compet.i.tive, to the higher or communistic att.i.tude. There may be a loss of energy, but there is a gain in the manner of applying it. The essayist should set himself to ascertain the truth upon a subject; he should not be anxious to make a case. The listeners, in the same spirit, should welcome all his suggestions, help him out where he is in difficulties, be indulgent to his failings, endeavour to see good in everything. If there be a real occasion for debate, it should be purposely forborne and reserved. In propounding subjects, the respective fitness for the debate and for the essay might be taken into account.

[CO-OPERATIVE DISCUSSION IN THE ESSAY.]

When questions have been often debated without coming nearer to a conclusion, it should be regarded as a sign that they are too delicate and subtle for debate. A trial should then be made of the amicable or co-operative treatment represented by the Essay. The Freedom of the Will might, I think, be adjusted by friendly accommodation, but not by force of contention. External Perception is beyond the province of debate.

It is fair and legitimate to try all problems by debate, in the first instance, because the excitement quickens the intelligence, and leads to new suggestions; but if the question involves an adjustment of various considerations and minute differences, the contending sides will be contentious still.

A society that really aims at the furtherance of knowledge, might test its operations by now and then preparing a report of progress; setting forth what problems had been debated, what themes elucidated, and with what results. It would be very refreshing to see a candid avowal that after several attempts--both debate and essay--some leading topic of the department remained exactly where it stood at the outset. After such a confession, the Society might well resolve itself into a Committee of the Whole House, to consider its ways, and indeed its entire position, with a view to a new start on some more hopeful track.

My closing remark is, as to avoiding debates that are in their very nature interminable. It is easy to fix upon a few salient features that make all the difference between a hopeful and a hopeless controversy.

For one thing, there is a certain intensity of emotion, interest, bias, or prejudice if you will, that can neither reason nor be reasoned with.

On the purely intellectual side, the disqualifying circ.u.mstances are complexity and vagueness. If a topic necessarily hauls in numerous other topics of difficulty, the essay may do something for it, but not the debate. Worst of all is the presence of several large, ill-defined, or unsettled terms, of which there are still plenty in our department. A not unfrequent case is a combination of the several defects each perhaps in a small degree. A tinge of predilection or party, a double or triple complication of doctrines, and one or two hazy terms, will make a debate that is pretty sure to end as it began. Thus it is that a question, plausible to appearance, may contain within it capacities of misunderstanding, cross-purposes, and pointless issues, sufficient to occupy the long night of Pandemonium, or beguile the journey to the nearest fixed star.

FOOTNOTES:

[Footnote 13: This very plausible utterance begs every question. There would be some difficulty in condensing an equal amount of fallacy, confusion of thought, in so few words.

In the first place, it a.s.sumes that the three requisites--health, freedom from debt, and a good conscience--are matters of easy and general attainment; that they are, in fact, the rule among human beings.

Is this really so?

Take Health, a word of very wide import. There is a certain small amount, such as is marked by being out of the physician's hands, but implying very little of the energy needed for the labours and the enjoyment of life. There is a high and resplendent degree that renders toil easy, and responds to the commonest stimulants, so that enjoyment cannot be quashed without unusually unfavourable circ.u.mstances. The first kind is widely diffused; the second is very rare, except in the earlier portion of life. Most men and women, as they pa.s.s middle age, lose the elasticity required for easy and spontaneous enjoyment, and, even if they keep the appearance of health, have too little animal spirits for enjoyment under cheap and ordinary excitements.
