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 mœnia mundi.” It may, indeed, if it chooses, feel a doubt of the completeness of its analysis hitherto, 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 [pg 433] will end; it will never trespass 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 anticipate 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, [pg 434] 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.

So far, then, as these remarks have gone, Theology and Physics cannot touch each other, have no intercommunion, have no ground of difference or agreement, of jealousy or of sympathy. As well may musical truths be said to interfere with the doctrines of architectural science; as well may there be a collision between the mechanist and the geologist, the engineer and the grammarian; as well might the British Parliament or the French nation be jealous of some possible belligerent power upon the surface of the moon, as Physics pick a quarrel with Theology. And it may be well,—before I proceed to fill up in detail this outline, and to explain what has to be explained in this statement,—to corroborate it, as it stands, by the remarkable words upon the subject of a writer of the day:[46]—
“We often hear it said,” he observes, writing as a Protestant (and here let me assure you, Gentlemen, that though his words have a controversial tone with them, I do not quote them in that aspect, or as wishing here to urge any thing against Protestants, but merely in pursuance of my own point, that Revelation and Physical Science cannot really come into collision), “we often hear it said that the world is constantly becoming more and more enlightened, and that this enlightenment must be favourable to Protestantism, and unfavourable to Catholicism. We wish that we could think so. But we see great reason to doubt whether this is a well-founded expectation. We see that during the last two hundred and fifty years the human mind has been in the highest degree active; that it has made great advances in every branch of natural philosophy; that it has produced innumerable [pg 436] inventions tending to promote the convenience of life; that medicine, surgery, chemistry, engineering, have been very greatly improved, that government, police, and law have been improved, though not to so great an extent as the physical sciences. Yet we see that, during these two hundred and fifty years, Protestantism has made no conquests worth speaking of. Nay, we believe that, as far as there has been change, that change has, on the whole, been in favour of the Church of Rome. We cannot, therefore, feel confident that the progress of knowledge will necessarily be fatal to a system which has, to say the least, stood its ground in spite of the immense progress made by the human race in knowledge since the days of Queen Elizabeth.
“Indeed, the argument which we are considering seems to us to be founded on an entire mistake. There are branches of knowledge with respect to which the law of the human mind is progress. In mathematics, when once a proposition has been demonstrated, it is never afterwards contested. Every fresh story is as solid a basis for a new superstructure as the original foundation was. Here, therefore, there is a constant addition to the stock of truth. In the inductive sciences, again, the law is progress.…
“But with theology the case is very different. As respects natural religion (Revelation being for the present altogether left out of the question), it is not easy to see that a philosopher of the present day is more favourably situated than Thales or Simonides. He has before him just the same evidences of design in the structure of the universe which the early Greeks had.… As to the other great question, the question what becomes of man after death, we do not see that a highly educated European, left to his unassisted reason, is more likely to be [pg 437] in the right than a Blackfoot Indian. Not a single one of the many sciences, in which we surpass the Blackfoot Indians, throws the smallest light on the state of the soul after the animal life is extinct.…
