Part 3 (1/2)

Now, it is not wonderful that, with all its capabilities, the human mind cannot take in this whole vast fact at a single glance, or gain possession of it at once. Like a short-sighted reader, its eye pores closely, and travels slowly, over the awful volume which lies open for its inspection.

Or again, as we deal with some huge structure of many parts and sides, the mind goes round about it, noting down, first one thing, then another, as it best may, and viewing it under different aspects, by way of making progress towards mastering the whole. So by degrees and by circuitous advances does it rise aloft and subject to itself a knowledge of that universe into which it has been born.

These various partial views or abstractions, by means of which the mind looks out upon its object, are called sciences, and embrace respectively larger or smaller portions of the field of knowledge; sometimes extending far and wide, but superficially, sometimes with exactness over particular departments, sometimes occupied together on one and the same portion, sometimes holding one part in common, and then ranging on this side or that in absolute divergence one from the other. Thus Optics has for its subject the whole visible creation, so far forth as it is simply visible; Mental Philosophy has a narrower province, but a richer one. Astronomy, plane and physical, each has the same subject-matter, but views it or treats it differently; lastly, Geology and Comparative Anatomy have subject-matters partly the same, partly distinct. Now these views or sciences, as being abstractions, have far more to do with the relations of things than with things themselves. They tell us what things are, only or princ.i.p.ally by telling us their relations, or a.s.signing predicates to subjects; and therefore they never tell us all that can be said about a thing, even when they tell something, nor do they bring it before us, as the senses do. They arrange and cla.s.sify facts; they reduce separate phenomena under a common law; they trace effects to a cause. Thus they serve to transfer our knowledge from the custody of memory to the surer and more abiding protection of philosophy, thereby providing both for its spread and its advance:-for, inasmuch as sciences are forms of knowledge, they enable the intellect to master and increase it; and, inasmuch as they are instruments, to communicate it readily to others. Still, after all, they proceed on the principle of a division of labour, even though that division is an abstraction, not a literal separation into parts; and, as the maker of a bridle or an epaulet has not, on that account, any idea of the science of tactics or strategy, so in a parallel way, it is not every science which equally, nor any one which fully, enlightens the mind in the knowledge of things, as they are, or brings home to it the external object on which it wishes to gaze. Thus they differ in importance; and according to their importance will be their influence, not only on the ma.s.s of knowledge to which they all converge and contribute, but on each other.

Since then sciences are the results of mental processes about one and the same subject-matter, viewed under its various aspects, and are true results, as far as they go, yet at the same time separate and partial, it follows that on the one hand they need external a.s.sistance, one by one, by reason of their incompleteness, and on the other that they are able to afford it to each other, by reason, first, of their independence in themselves, and then of their connexion in their subject-matter. Viewed altogether, they approximate to a representation or subjective reflection of the objective truth, as nearly as is possible to the human mind, which advances towards the accurate apprehension of that object, in proportion to the number of sciences which it has mastered; and which, when certain sciences are away, in such a case has but a defective apprehension, in proportion to the value of the sciences which are thus wanting, and the importance of the field on which they are employed.

3.

Let us take, for instance, man himself as our object of contemplation; then at once we shall find we can view him in a variety of relations; and according to those relations are the sciences of which he is the subject-matter, and according to our acquaintance with them is our possession of a true knowledge of him. We may view him in relation to the material elements of his body, or to his mental const.i.tution, or to his household and family, or to the community in which he lives, or to the Being who made him; and in consequence we treat of him respectively as physiologists, or as moral philosophers, or as writers of economics, or of politics, or as theologians. When we think of him in all these relations together, or as the subject at once of all the sciences I have named, then we may be said to reach unto and rest in the idea of man as an object or external fact, similar to that which the eye takes of his outward form. On the other hand, according as we are only physiologists, or only politicians, or only moralists, so is our idea of man more or less unreal; we do not take in the whole of him, and the defect is greater or less, in proportion as the relation is, or is not, important, which is omitted, whether his relation to G.o.d, or to his king, or to his children, or to his own component parts. And if there be one relation, about which we know nothing at all except that it exists, then is our knowledge of him, confessedly and to our own consciousness, deficient and partial, and that, I repeat, in proportion to the importance of the relation.

That therefore is true of sciences in general which we are apt to think applies only to pure mathematics, though to pure mathematics it applies especially, viz., that they cannot be considered as simple representations or informants of things as they are. We are accustomed to say, and say truly, that the conclusions of pure mathematics are applied, corrected, and adapted, by mixed; but so too the conclusions of Anatomy, Chemistry, Dynamics, and other sciences, are revised and completed by each other.

Those several conclusions do not represent whole and substantive things, but views, true, so far as they go; and in order to ascertain how far they do go, that is, how far they correspond to the object to which they belong, we must compare them with the views taken out of that object by other sciences. Did we proceed upon the abstract theory of forces, we should a.s.sign a much more ample range to a projectile than in fact the resistance of the air allows it to accomplish. Let, however, that resistance be made the subject of scientific a.n.a.lysis, and then we shall have a new science, a.s.sisting, and to a certain point completing, for the benefit of questions of fact, the science of projection. On the other hand, the science of projection itself, considered as belonging to the forces it contemplates, is not more perfect, as such, by this supplementary investigation. And in like manner, as regards the whole circle of sciences, one corrects another for purposes of fact, and one without the other cannot dogmatize, except hypothetically and upon its own abstract principles. For instance, the Newtonian philosophy requires the admission of certain metaphysical postulates, if it is to be more than a theory or an hypothesis; as, for instance, that what happened yesterday will happen to-morrow; that there is such a thing as matter, that our senses are trustworthy, that there is a logic of induction, and so on. Now to Newton metaphysicians grant all that he asks; but, if so be, they may not prove equally accommodating to another who asks something else, and then all his most logical conclusions in the science of physics would remain hopelessly on the stocks, though finished, and never could be launched into the sphere of fact.

Again, did I know nothing about the movement of bodies, except what the theory of gravitation supplies, were I simply absorbed in that theory so as to make it measure all motion on earth and in the sky, I should indeed come to many right conclusions, I should hit off many important facts, ascertain many existing relations, and correct many popular errors: I should scout and ridicule with great success the old notion, that light bodies flew up and heavy bodies fell down; but I should go on with equal confidence to deny the phenomenon of capillary attraction. Here I should be wrong, but only because I carried out my science irrespectively of other sciences. In like manner, did I simply give myself to the investigation of the external action of body upon body, I might scoff at the very idea of chemical affinities and combinations, and reject it as simply unintelligible. Were I a mere chemist, I should deny the influence of mind upon bodily health; and so on, as regards the devotees of any science, or family of sciences, to the exclusion of others; they necessarily become bigots and quacks, scorning all principles and reported facts which do not belong to their own pursuit, and thinking to effect everything without aid from any other quarter. Thus, before now, chemistry has been subst.i.tuted for medicine; and again, political economy, or intellectual enlightenment, or the reading of the Scriptures, has been cried up as a panacea against vice, malevolence, and misery.

4.

Summing up, Gentlemen, what I have said, I lay it down that all knowledge forms one whole, because its subject-matter is one; for the universe in its length and breadth is so intimately knit together, that we cannot separate off portion from portion, and operation from operation, except by a mental abstraction; and then again, as to its Creator, though He of course in His own Being is infinitely separate from it, and Theology has its departments towards which human knowledge has no relations, yet He has so implicated Himself with it, and taken it into His very bosom, by His presence in it, His providence over it, His impressions upon it, and His influences through it, that we cannot truly or fully contemplate it without in some main aspects contemplating Him. Next, sciences are the results of that mental abstraction, which I have spoken of, being the logical record of this or that aspect of the whole subject-matter of knowledge. As they all belong to one and the same circle of objects, they are one and all connected together; as they are but aspects of things, they are severally incomplete in their relation to the things themselves, though complete in their own idea and for their own respective purposes; on both accounts they at once need and subserve each other. And further, the comprehension of the bearings of one science on another, and the use of each to each, and the location and limitation and adjustment and due appreciation of them all, one with another, this belongs, I conceive, to a sort of science distinct from all of them, and in some sense a science of sciences, which is my own conception of what is meant by Philosophy, in the true sense of the word, and of a philosophical habit of mind, and which in these Discourses I shall call by that name. This is what I have to say about knowledge and philosophical knowledge generally; and now I proceed to apply it to the particular science, which has led me to draw it out.

I say, then, that the systematic omission of any one science from the catalogue prejudices the accuracy and completeness of our knowledge altogether, and that, in proportion to its importance. Not even Theology itself, though it comes from heaven, though its truths were given once for all at the first, though they are more certain on account of the Giver than those of mathematics, not even Theology, so far as it is relative to us, or is the Science of Religion, do I exclude from the law to which every mental exercise is subject, viz., from that imperfection, which ever must attend the abstract, when it would determine the concrete. Nor do I speak only of Natural Religion; for even the teaching of the Catholic Church, in certain of its aspects, that is, its religious teaching, is variously influenced by the other sciences. Not to insist on the introduction of the Aristotelic philosophy into its phraseology, its explanation of dogmas is influenced by ecclesiastical acts or events; its interpretations of prophecy are directly affected by the issues of history; its comments upon Scripture by the conclusions of the astronomer and the geologist; and its casuistical decisions by the various experience, political, social, and psychological, with which times and places are ever supplying it.

What Theology gives, it has a right to take; or rather, the interests of Truth oblige it to take. If we would not be beguiled by dreams, if we would ascertain facts as they are, then, granting Theology is a real science, we cannot exclude it, and still call ourselves philosophers. I have a.s.serted nothing as yet as to the pre-eminent dignity of Religious Truth; I only say, if there be Religious Truth at all, we cannot shut our eyes to it without prejudice to truth of every kind, physical, metaphysical, historical, and moral; for it bears upon all truth. And thus I answer the objection with which I opened this Discourse. I supposed the question put to me by a philosopher of the day, ”Why cannot you go your way, and let us go ours?” I answer, in the name of the Science of Religion, ”When Newton can dispense with the metaphysician, then may you dispense with us.” So much at first sight; now I am going on to claim a little more for Theology, by cla.s.sing it with branches of knowledge which may with greater decency be compared to it.

5.

Let us see, then, how this supercilious treatment of so momentous a science, for momentous it must be, if there be a G.o.d, runs in a somewhat parallel case. The great philosopher of antiquity, when he would enumerate the causes of the things that take place in the world, after making mention of those which he considered to be physical and material, adds, ”and the mind and everything which is by means of man.”(8) Certainly; it would have been a preposterous course, when he would trace the effects he saw around him to their respective sources, had he directed his exclusive attention upon some one cla.s.s or order of originating principles, and ascribed to these everything which happened anywhere. It would indeed have been unworthy a genius so curious, so penetrating, so fertile, so a.n.a.lytical as Aristotle's, to have laid it down that everything on the face of the earth could be accounted for by the material sciences, without the hypothesis of moral agents. It is incredible that in the investigation of physical results he could ignore so influential a being as man, or forget that, not only brute force and elemental movement, but knowledge also is power. And this so much the more, inasmuch as moral and spiritual agents belong to another, not to say a higher, order than physical; so that the omission supposed would not have been merely an oversight in matters of detail, but a philosophical error, and a fault in division.

However, we live in an age of the world when the career of science and literature is little affected by what was done, or would have been done, by this venerable authority; so, we will suppose, in England or Ireland, in the middle of the nineteenth century, a set of persons of name and celebrity to meet together, in spite of Aristotle, in order to adopt a line of proceeding which they conceive the circ.u.mstances of the time render imperative. We will suppose that a difficulty just now besets the enunciation and discussion of all matters of science, in consequence of the extreme sensitiveness of large cla.s.ses of the community, clergy and laymen, on the subjects of necessity, responsibility, the standard of morals, and the nature of virtue. Parties run so high, that the only way of avoiding constant quarrelling in defence of this or that side of the question is, in the judgment of the persons I am supposing, to shut up the subject of anthropology altogether. This is accordingly done. Henceforth man is to be as if he were not, in the general course of Education; the moral and mental sciences are to have no professorial chairs, and the treatment of them is to be simply left as a matter of private judgment, which each individual may carry out as he will. I can just fancy such a prohibition abstractedly possible; but one thing I cannot fancy possible, viz., that the parties in question, after this sweeping act of exclusion, should forthwith send out proposals on the basis of such exclusion for publis.h.i.+ng an Encyclopaedia, or erecting a National University.

It is necessary, however, Gentlemen, for the sake of the ill.u.s.tration which I am setting before you, to imagine what cannot be. I say, let us imagine a project for organizing a system of scientific teaching, in which the agency of man in the material world cannot allowably be recognized, and may allowably be denied. Physical and mechanical causes are exclusively to be treated of; volition is a forbidden subject. A prospectus is put out, with a list of sciences, we will say, Astronomy, Optics, Hydrostatics, Galvanism, Pneumatics, Statics, Dynamics, Pure Mathematics, Geology, Botany, Physiology, Anatomy, and so forth; but not a word about the mind and its powers, except what is said in explanation of the omission. That explanation is to the effect that the parties concerned in the undertaking have given long and anxious thought to the subject, and have been reluctantly driven to the conclusion that it is simply impracticable to include in the list of University Lectures the Philosophy of Mind. What relieves, however, their regret is the reflection, that domestic feelings and polished manners are best cultivated in the family circle and in good society, in the observance of the sacred ties which unite father, mother, and child, in the correlative claims and duties of citizens.h.i.+p, in the exercise of disinterested loyalty and enlightened patriotism. With this apology, such as it is, they pa.s.s over the consideration of the human mind and its powers and works, ”in solemn silence,” in their scheme of University Education.

Let a charter be obtained for it; let professors be appointed, lectures given, examinations pa.s.sed, degrees awarded:-what sort of exactness or trustworthiness, what philosophical largeness, will attach to views formed in an intellectual atmosphere thus deprived of some of the const.i.tuent elements of daylight? What judgment will foreign countries and future times pa.s.s on the labours of the most acute and accomplished of the philosophers who have been parties to so portentous an unreality? Here are professors gravely lecturing on medicine, or history, or political economy, who, so far from being bound to acknowledge, are free to scoff at the action of mind upon matter, or of mind upon mind, or the claims of mutual justice and charity. Common sense indeed and public opinion set bounds at first to so intolerable a licence; yet, as time goes on, an omission which was originally but a matter of expedience, commends itself to the reason; and at length a professor is found, more hardy than his brethren, still however, as he himself maintains, with sincere respect for domestic feelings and good manners, who takes on him to deny psychology _in toto_, to p.r.o.nounce the influence of mind in the visible world a superst.i.tion, and to account for every effect which is found in the world by the operation of physical causes. Hitherto intelligence and volition were accounted real powers; the muscles act, and their action cannot be represented by any scientific expression; a stone flies out of the hand and the propulsive force of the muscle resides in the will; but there has been a revolution, or at least a new theory in philosophy, and our Professor, I say, after speaking with the highest admiration of the human intellect, limits its independent action to the region of speculation, and denies that it can be a motive principle, or can exercise a special interference, in the material world. He ascribes every work, every external act of man, to the innate force or soul of the physical universe.

He observes that spiritual agents are so mysterious and unintelligible, so uncertain in their laws, so vague in their operation, so sheltered from experience, that a wise man will have nothing to say to them. They belong to a different order of causes, which he leaves to those whose profession it is to investigate them, and he confines himself to the tangible and sure. Human exploits, human devices, human deeds, human productions, all that comes under the scholastic terms of ”genius” and ”art,” and the metaphysical ideas of ”duty,” ”right,” and ”heroism,” it is his office to contemplate all these merely in their place in the eternal system of physical cause and effect. At length he undertakes to show how the whole fabric of material civilization has arisen from the constructive powers of physical elements and physical laws. He descants upon palaces, castles, temples, exchanges, bridges, causeways, and shows that they never could have grown into the imposing dimensions which they present to us, but for the laws of gravitation and the cohesion of part with part. The pillar would come down, the loftier the more speedily, did not the centre of gravity fall within its base; and the most admired dome of Palladio or of Sir Christopher would give way, were it not for the happy principle of the arch. He surveys the complicated machinery of a single day's arrangements in a private family; our dress, our furniture, our hospitable board; what would become of them, he asks, but for the laws of physical nature? Those laws are the causes of our carpets, our furniture, our travelling, and our social intercourse. Firm st.i.tches have a natural power, in proportion to the toughness of the material adopted, to keep together separate portions of cloth; sofas and chairs could not turn upside down, even if they would; and it is a property of caloric to relax the fibres of animal matter, acting through water in one way, through oil in another, and this is the whole mystery of the most elaborate _cuisine_:-but I should be tedious if I continued the ill.u.s.tration.

6.

Now, Gentlemen, pray understand how it is to be here applied. I am not supposing that the principles of Theology and Psychology are the same, or arguing from the works of man to the works of G.o.d, which Paley has done, which Hume has protested against. I am not busying myself to prove the existence and attributes of G.o.d, by means of the Argument from design. I am not proving anything at all about the Supreme Being. On the contrary, I am a.s.suming His existence, and I do but say this:-that, man existing, no University Professor, who had suppressed in physical lectures the idea of volition, who did not take volition for granted, could escape a one-sided, a radically false view of the things which he discussed; not indeed that his own definitions, principles, and laws would be wrong, or his abstract statements, but his considering his own study to be the key of everything that takes place on the face of the earth, and his pa.s.sing over anthropology, this would be his error. I say, it would not be his science which was untrue, but his so-called knowledge which was unreal. He would be deciding on facts by means of theories. The various busy world, spread out before our eyes, is physical, but it is more than physical; and, in making its actual system identical with his scientific a.n.a.lysis, formed on a particular aspect, such a Professor as I have imagined was betraying a want of philosophical depth, and an ignorance of what an University Teaching ought to be. He was no longer a teacher of liberal knowledge, but a narrow-minded bigot. While his doctrines professed to be conclusions formed upon an hypothesis or partial truth, they were undeniable; not so if they professed to give results in facts which he could grasp and take possession of. Granting, indeed, that a man's arm is moved by a simple physical cause, then of course we may dispute about the various external influences which, when it changes its position, sway it to and fro, like a scarecrow in a garden; but to a.s.sert that the motive cause _is_ physical, this is an a.s.sumption in a case, when our question is about a matter of fact, not about the logical consequences of an a.s.sumed premiss. And, in like manner, if a people prays, and the wind changes, the rain ceases, the sun s.h.i.+nes, and the harvest is safely housed, when no one expected it, our Professor may, if he will, consult the barometer, discourse about the atmosphere, and throw what has happened into an equation, ingenious, even though it be not true; but, should he proceed to rest the phenomenon, in matter of fact, simply upon a physical cause, to the exclusion of a divine, and to say that the given case actually belongs to his science because other like cases do, I must tell him, _Ne sutor ultra crepidam_: he is making his particular craft usurp and occupy the universe. This then is the drift of my ill.u.s.tration. If the creature is ever setting in motion an endless series of physical causes and effects, much more is the Creator; and as our excluding volition from our range of ideas is a denial of the soul, so our ignoring Divine Agency is a virtual denial of G.o.d.

Moreover, supposing man can will and act of himself in spite of physics, to shut up this great truth, though one, is to put our whole encyclopaedia of knowledge out of joint; and supposing G.o.d can will and act of Himself in this world which He has made, and we deny or slur it over, then we are throwing the circle of universal science into a like, or a far worse confusion.
