Part 26 (2/2)

They must issue fresh and fresh, as from the preacher's mouth, so from his breast, if they are to be ”spirit and life” to the hearts of his hearers.

And what is true of a parish priest applies, _mutatis mutandis_, to a University preacher; who, even more, perhaps, than the ordinary _parochus_, comes to his audience with a name and a history, and excites a personal interest, and persuades by what he is, as well as by what he delivers.

I am far from forgetting that every one has his own talent, and that one has not what another has. Eloquence is a divine gift, which to a certain point supersedes rules, and is to be used, like other gifts, to the glory of the Giver, and then only to be discountenanced when it forgets its place, when it throws into the shade and embarra.s.ses the essential functions of the Christian preacher, and claims to be cultivated for its own sake instead of being made subordinate and subservient to a higher work and to sacred objects. And how to make eloquence subservient to the evangelical office is not more difficult than how to use learning or intellect for a supernatural end; but it does not come into consideration here.

In the case of particular preachers, circ.u.mstances may constantly arise which render the use of a ma.n.u.script the more advisable course; but I have been considering how the case stands in itself, and attempting to set down what is to be aimed at as best. If religious men once ascertain what is abstractedly desirable, and acquiesce in it with their hearts, they will be in the way to get over many difficulties which otherwise will be insurmountable. For myself, I think it no extravagance to say that a very inferior sermon, delivered without book, answers the purposes for which all sermons are delivered more perfectly than one of great merit, if it be written and read. Of course, all men will not speak without book equally well, just as their voices are not equally clear and loud, or their manner equally impressive. Eloquence, I repeat, is a gift; but most men, unless they have pa.s.sed the age for learning, may with practice attain such fluency in expressing their thoughts as will enable them to convey and manifest to their audience that earnestness and devotion to their object, which is the life of preaching,-which both covers, in the preacher's own consciousness, the sense of his own deficiencies, and makes up for them over and over again in the judgment of his hearers.

Lecture VII.

Christianity and Physical Science. A Lecture in the School of Medicine.

1.

Now that we have just commenced our second Academical Year, it is natural, Gentlemen, that, as in November last, when we were entering upon our great undertaking, I offered to you some remarks suggested by the occasion, so now again I should not suffer the first weeks of the Session to pa.s.s away without addressing to you a few words on one of those subjects which are at the moment especially interesting to us. And when I apply myself to think what topic I shall in consequence submit to your consideration, I seem to be directed what to select by the principle of selection which I followed on that former occasion to which I have been referring. Then(45) we were opening the Schools of Philosophy and Letters, as now we are opening those of Medicine; and, as I then attempted some brief investigation of the mutual bearings of Revelation and Literature, so at the present time I shall not, I trust, be unprofitably engaging your attention, if I make one or two parallel reflections on the relations existing between Revelation and Physical Science.

This subject, indeed, viewed in its just dimensions, is far too large for an occasion such as this; still I may be able to select some one point out of the many which it offers for discussion, and, while elucidating it, to throw light even on others which at the moment I do not formally undertake. I propose, then, to discuss the antagonism which is popularly supposed to exist between Physics and Theology; and to show, first, that such antagonism does not really exist, and, next, to account for the circ.u.mstance that so groundless an imagination should have got abroad.

I think I am not mistaken in the fact that there exists, both in the educated and half-educated portions of the community, something of a surmise or misgiving, that there really is at bottom a certain contrariety between the declarations of religion and the results of physical inquiry; a suspicion such, that, while it encourages those persons who are not over-religious to antic.i.p.ate a coming day, when at length the difference will break out into open conflict, to the disadvantage of Revelation, it leads religious minds, on the other hand, who have not had the opportunity of considering accurately the state of the case, to be jealous of the researches, and prejudiced against the discoveries, of Science. The consequence is, on the one side, a certain contempt of Theology; on the other, a disposition to undervalue, to deny, to ridicule, to discourage, and almost to denounce, the labours of the physiological, astronomical, or geological investigator.

I do not suppose that any of those gentlemen who are now honouring me with their presence are exposed to the temptation either of the religious or of the scientific prejudice; but that is no reason why some notice of it may not have its use even in this place. It may lead us to consider the subject itself more carefully and exactly; it may a.s.sist us in attaining clearer ideas than before how Physics and Theology stand relatively to each other.

2.

Let us begin with a first approximation to the real state of the case, or a broad view, which, though it may require corrections, will serve at once to ill.u.s.trate and to start the subject. We may divide knowledge, then, into natural and supernatural. Some knowledge, of course, is both at once; for the moment let us put this circ.u.mstance aside, and view these two fields of knowledge in themselves, and as distinct from each other in idea. By nature is meant, I suppose, that vast system of things, taken as a whole, of which we are cognizant by means of our natural powers. By the supernatural world is meant that still more marvellous and awful universe, of which the Creator Himself is the fulness, and which becomes known to us, not through our natural faculties, but by superadded and direct communication from Him. These two great circles of knowledge, as I have said, intersect; first, as far as supernatural knowledge includes truths and facts of the natural world, and secondly, as far as truths and facts of the natural world are on the other hand data for inferences about the supernatural. Still, allowing this interference to the full, it will be found, on the whole, that the two worlds and the two kinds of knowledge respectively are separated off from each other; and that, therefore, as being separate, they cannot on the whole contradict each other. That is, in other words, a person who has the fullest knowledge of one of these worlds, may be nevertheless, on the whole, as ignorant as the rest of mankind, as unequal to form a judgment, of the facts and truths of the other. He who knows all that can possibly be known about physics, about politics, about geography, ethnology, and ethics, will have made no approximation whatever to decide the question whether or not there are angels, and how many are their orders; and on the other hand, the most learned of dogmatic and mystical divines,-St. Augustine, St. Thomas,-will not on that score know more than a peasant about the laws of motion, or the wealth of nations. I do not mean that there may not be speculations and guesses on this side and that, but I speak of any conclusion which merits to be called, I will not say knowledge, but even opinion. If, then, Theology be the philosophy of the supernatural world, and Science the philosophy of the natural, Theology and Science, whether in their respective ideas, or again in their own actual fields, on the whole, are incommunicable, incapable of collision, and needing, at most to be connected, never to be reconciled.

Now this broad general view of our subject is found to be so far true in fact, in spite of such deductions from it that have to be made in detail, that the recent French editors of one of the works of St. Thomas are able to give it as one of their reasons why that great theologian made an alliance, not with Plato, but with Aristotle, because Aristotle (they say), unlike Plato, confined himself to human science, and therefore was secured from coming into collision with divine.

”Not without reason,” they say, ”did St. Thomas acknowledge Aristotle as if the Master of human philosophy; for, inasmuch as Aristotle was not a Theologian, he had only treated of logical, physical, psychological, and metaphysical theses, to the exclusion of those which are concerned about the supernatural relations of man to G.o.d, that is, religion; which, on the other hand, had been the source of the worst errors of other philosophers, and especially of Plato.”

3.

But if there be so substantial a truth even in this very broad statement concerning the independence of the fields of Theology and general Science severally, and the consequent impossibility of collision between them, how much more true is that statement, from the very nature of the case, when we contrast Theology, not with Science generally, but definitely with Physics! In Physics is comprised that family of sciences which is concerned with the sensible world, with the phenomena which we see, hear, and handle, or, in other words, with matter. It is the philosophy of matter. Its basis of operations, what it starts from, what it falls back upon, is the phenomena which meet the senses. Those phenomena it ascertains, catalogues, compares, combines, arranges, and then uses for determining something beyond themselves, viz., the order to which they are subservient, or what we commonly call the laws of nature. It never travels beyond the examination of cause and effect. Its object is to resolve the complexity of phenomena into simple elements and principles; but when it has reached those first elements, principles, and laws, its mission is at an end; it keeps within that material system with which it began, and never ventures beyond the ”flammantia mnia mundi.” It may, indeed, if it chooses, feel a doubt of the completeness of its a.n.a.lysis. .h.i.therto, and for that reason endeavour to arrive at more simple laws and fewer principles. It may be dissatisfied with its own combinations, hypotheses, systems; and leave Ptolemy for Newton, the alchemists for Lavoisier and Davy;-that is, it may decide that it has not yet touched the bottom of its own subject; but still its aim will be to get to the bottom, and nothing more. With matter it began, with matter it will end; it will never trespa.s.s into the province of mind. The Hindoo notion is said to be that the earth stands upon a tortoise; but the physicist, as such, will never ask himself by what influence, external to the universe, the universe is sustained; simply because he _is_ a physicist.

If indeed he be a religious man, he will of course have a very definite view of the subject; but that view of his is private, not professional,-the view, not of a physicist, but of a religious man; and this, not because physical science says any thing different, but simply because it says nothing at all on the subject, nor can do so by the very undertaking with which it set out. The question is simply _extra artem_.

The physical philosopher has nothing whatever to do with final causes, and will get into inextricable confusion, if he introduces them into his investigations. He has to look in one definite direction, not in any other. It is said that in some countries, when a stranger asks his way, he is at once questioned in turn what place he came from: something like this would be the unseasonableness of a physicist, who inquired how the phenomena and laws of the material world primarily came to be, when his simple task is that of ascertaining what they are. Within the limits of those phenomena he may speculate and prove; he may trace the operation of the laws of matter through periods of time; he may penetrate into the past, and antic.i.p.ate the future; he may recount the changes which they have effected upon matter, and the rise, growth, and decay of phenomena; and so in a certain sense he may write the history of the material world, as far as he can; still he will always advance from phenomena, and conclude upon the internal evidence which they supply. He will not come near the questions, what that ultimate element is, which we call matter, how it came to be, whether it can cease to be, whether it ever was not, whether it will ever come to nought, in what its laws really consist, whether they can cease to be, whether they can be suspended, what causation is, what time is, what the relations of time to cause and effect, and a hundred other questions of a similar character.

Such is Physical Science, and Theology, as is obvious, is just what such Science is not. Theology begins, as its name denotes, not with any sensible facts, phenomena, or results, not with nature at all, but with the Author of nature,-with the one invisible, unapproachable Cause and Source of all things. It begins at the other end of knowledge, and is occupied, not with the finite, but the Infinite. It unfolds and systematizes what He Himself has told us of Himself; of His nature, His attributes, His will, and His acts. As far as it approaches towards Physics, it takes just the counterpart of the questions which occupy the Physical Philosopher. He contemplates facts before him; the Theologian gives the reasons of those facts. The Physicist treats of efficient causes; the Theologian of final. The Physicist tells us of laws; the Theologian of the Author, Maintainer, and Controller of them; of their scope, of their suspension, if so be; of their beginning and their end.

This is how the two schools stand related to each other, at that point where they approach the nearest; but for the most part they are absolutely divergent. What Physical Science is engaged in I have already said; as to Theology, it contemplates the world, not of matter, but of mind; the Supreme Intelligence; souls and their destiny; conscience and duty; the past, present, and future dealings of the Creator with the creature.
