‘Now I do not quarrel with these ancients,’ continues the letter-writer, ‘so much on account of the transparent frivolity of their logic – which, to be plain, was baseless, worthless and fantastic altogether – as on account of their pompous and infatuate proscription of all other roads to Truth than the two narrow and crooked paths – the one of creeping and the other of crawling – to which, in their ignorant perversity, they have dared to confine the Soul – the Soul which loves nothing so well as to soar in those regions of illimitable intuition which are utterly incognizant of “path”.
‘By the bye, my dear friend, is it not an evidence of the mental slavery entailed upon those bigoted people by their Hogs and Rams, that in spite of the eternal prating of their savans about roads to Truth, none of them fell, even by accident, into what we now so distinctly perceive to be the broadest, the straightest and most available of all mere roads – the great thoroughfare – the majestic highway of the Consistent? Is it not wonderful that they should have failed to deduce from the works of God the vitally momentous consideration that a perfect consistency can be nothing but an absolute truth? How plain – how rapid our progress since the late announcement of this proposition! By its means, investigation has been taken out of the hands of the ground-moles, and given as a duty, rather than as a task, to the true – to the only true thinkers – to the generally-educated men of ardent imagination. These latter – our Keplers – our Laplaces – “speculate” – “theorize” – these are the terms – can you not fancy the shout of scorn with which they would be received by our progenitors, were it possible for them to be looking over my shoulders as I write? The Keplers, I repeat, speculate – theorize – and their theories are merely corrected – reduced – sifted – cleared, little by little, of their chaff of inconsistency – until at length there stands apparent an unencumbered Consistency – a consistency which the most stolid admit – because it is a consistency – to be an absolute and unquestionable Truth.
‘I have often thought, my friend, that it must have puzzled these dogmaticians of a thousand years ago, to determine, even, by which of their two boasted roads it is that the cryptographist attains the solution of the more complicated cyphers – or by which of them Champollion guided mankind to those important and innumerable truths which, for so many centuries, have lain entombed amid the phonetical hieroglyphics of Egypt.12 In especial, would it not have given these bigots some trouble to determine by which of their two roads was reached the most momentous and sublime of all their truths – the truth – the fact of gravitation? Newton deduced it from the laws of Kepler. Kepler admitted that these laws he guessed – these laws whose investigation disclosed to the greatest of British astronomers that principle, the basis of all (existing) physical principle, in going behind which we enter at once the nebulous kingdom of Metaphysics. Yes! – these vital laws Kepler guessed – that it is to say, he imagined them. Had he been asked to point out either the deductive or inductive route by which he attained them, his reply might have been – “I know nothing about routes – but I do know the machinery of the Universe. Here it is. I grasped it with my soul – I reached it through mere dint of intuition.” Alas, poor ignorant old man! Could not any metaphysician have told him that what he called “intuition” was but the conviction resulting from deductions or inductions of which the processes were so shadowy as to have escaped his consciousness, eluded his reason, or bidden defiance to his capacity of expression? How great a pity it is that some “moral philosopher” had not enlightened him about all this! How it would have comforted him on his death-bed to know that, instead of having gone intuitively and thus unbecomingly, he had, in fact, proceeded decorously and legitimately – that is to say Hog-ishly, or at least Ram-ishly – into the vast halls where lay gleaming, untended, and hitherto untouched by mortal hand – unseen by mortal eye – the imperishable and priceless secrets of the Universe!
‘Yes, Kepler was essentially a theorist; but this title, now of so much sanctity, was, in those ancient days, a designation of supreme contempt. It is only now that men begin to appreciate that divine old man – to sympathize with the prophetical and poetical rhapsody of his ever-memorable words. For my part,’ continues the unknown correspondent, ‘I glow with a sacred fire when I even think of them, and feel that I shall never grow weary of their repetition: – in concluding this letter, let me have the real pleasure of transcribing them once again: – “I care not whether my work be read now or by posterity. I can afford to wait a century for readers13 when God himself has waited six thousand years for an observer. I triumph. I have stolen the golden secret of the Egyptians. I will indulge my sacred fury.” ’
Here end my quotations from this very unaccountable if not impertinent epistle; and perhaps it would be folly to comment, in any respect, upon the chimerical, not to say revolutionary, fancies of the writer – whoever he is – fancies so radically at war with the well-considered and well-settled opinions of this age. Let us proceed, then, to our legitimate thesis, The Universe.
This thesis admits a choice between two modes of discussion : – We may ascend or descend. Beginning at our own point of view – at the Earth on which we stand – we may pass to the other planets of our system – thence to the Sun – thence to our system considered collectively – and thence, through other systems, indefinitely outwards; or, commencing on high at some point as definite as we can make it or conceive it, we may come down to the habitation of Man. Usually – that is to say, in ordinary essays on Astronomy – the first of these two modes is, with certain reservation, adopted: – this for the obvious reason that astronomical facts, merely, and principles, being the object, that object is best fulfilled in stepping from the known because proximate, gradually onward to the point where all certitude becomes lost in the remote. For my present purpose, however, – that of enabling the mind to take in, as if from afar and at one glance, a distant conception of the individual Universe – it is clear that a descent to small from great – to the outskirts from the centre (if we could establish a centre) – to the end from the beginning (if we could fancy a beginning) would be the preferable course, but for the difficulty, if not impossibility, of presenting, in this course, to the unastronomical, a picture at all comprehensible in regard to such considerations as are involved in quantity – that is to say, in number, magnitude and distance.
Now, distinctness – intelligibility, at all points, is a primary feature in my general design. On important topics it is better to be a good deal prolix than even a very little obscure. But abstruseness is a quality appertaining to no subject in itself. All are alike, in facility of comprehension, to him who approaches them by properly graduated steps. It is merely because a stepping-stone, here and there, is heedlessly left unsupplied in our road to the Differential Calculus, that this latter is not altogether as simple a thing as a sonnet by Mr Solomon Seesaw.14
By way of admitting, then, no chance for misapprehension, I think it advisable to proceed as if even the more obvious facts of Astronomy were unknown to the reader. In combining the two modes of discussion to which I have referred, I propose to avail myself of the advantages peculiar to each – and very especially of the iteration in detail which will be unavoidable as a consequence of the plan. Commencing with a descent, I shall reserve for the return upwards those indispensable considerations of quantity to which allusion has already been made.
Let us begin, then, at once, with that merest of words, ‘Infinity’. This, like ‘God’, ‘spirit’, and some other expressions of which the equivalents exist in nearly all languages, is by no means the expression of an idea – but of an effort at one. It stands for the possible attempt at an impossible conception. Man needed a term by which to point out the direction of this effort – the cloud behind which lay, forever invisible, the object of this attempt. A word, in fine, was demanded, by means of which one human being might put himself in relation at once with another human being and with a certain tendency of the human intellect. Out of this dema
nd arose the word, ‘Infinity’; which is thus the representative but of the thought of a thought.
As regards that infinity now considered – the infinity of space – we often hear it said that ‘its idea is admitted by the mind – is acquiesced in – is entertained – on account of the greater difficulty which attends the conception of a limit’. But this is merely one of those phrases by which even profound thinkers, time out of mind, have occasionally taken pleasure in deceiving themselves. The quibble lies concealed in the word ‘difficulty’. ‘The mind,’ we are told, ‘entertains the idea of limitless, through the greater difficulty which it finds in entertaining that of limited, space.’ Now, were the proposition but fairly put, its absurdity would become transparent at once. Clearly, there is no mere difficulty in the case. The assertion intended, if presented according to its intention and without sophistry, would run thus: – ‘The mind admits the idea of limitless, through the greater impossibility of entertaining that of limited, space.’
It must be immediately seen that this is not a question of two statements between whose respective credibilities – or of two arguments between whose respective validities – the reason is called upon to decide : – it is a matter of two conceptions, directly conflicting, and each avowedly impossible, one of which the intellect is supposed to be capable of entertaining, on account of the greater impossibility of entertaining the other. The choice is not made between two difficulties; – it is merely fancied to be made between two impossibilities. Now of the former, there are degrees, – but of the latter, none: – just as our impertinent letter-writer has already suggested. A task may be more or less difficult; but it is either possible or not possible: – there are no gradations. It might be more difficult to overthrow the Andes than an ant-hill: but it can be no more impossible to annihilate the matter of the one than the matter of the other. A man may jump ten feet with less difficulty than he can jump twenty, but the impossibility of his leaping to the moon is not a whit less than that of his leaping to the dog-star.
Since all this is undeniable : since the choice of the mind is to be made between impossibilities of conception: since one impossibility cannot be greater than another: and since, thus, one cannot be preferred to another: the philosophers who not only maintain, on the grounds mentioned, man’s idea of infinity but, on account of such supposititious idea, infinity itself – are plainly engaged in demonstrating one impossible thing to be possible by showing how it is that some one other thing – is impossible too. This, it will be said, is nonsense; and perhaps it is: – indeed I think it very capital nonsense – but forgo all claim to it as nonsense of mine.
The readiest mode, however, of displaying the fallacy of the philosophical argument on this question, is by simply adverting to a fact respecting it which has been hitherto quite overlooked – the fact that the argument alluded to both proves and disproves its own proposition. ‘The mind is impelled,’ say the theologians and others, ‘to admit a First Cause, by the superior difficulty it experiences in conceiving cause beyond cause without end.’ The quibble, as before, lies in the word ‘difficulty’ – but here what is it employed to sustain? A First Cause. And what is a First Cause? An ultimate termination of causes. And what is an ultimate termination of causes? Finity – the Finite. Thus the one quibble, in two processes, by God knows how many philosophers, is made to support now Finity and now Infinity – could it not be brought to support something besides? As for the quibblers – they, at least, are insupportable. But – to dismiss them: – what they prove in the one case is the identical nothing which they demonstrate in the other.
Of course, no one will suppose that I here contend for the absolute impossibility of that which we attempt to convey in the word ‘Infinity’. My purpose is but to show the folly of endeavoring to prove Infinity itself, or even our conception of it, by any such blundering ratiocination as that which is ordinarily employed.
Nevertheless, as an individual, I may be permitted to say that I cannot conceive Infinity, and am convinced that no human being can. A mind not thoroughly self-conscious – not accustomed to the introspective analysis of its own operations – will, it is true, often deceive itself by supposing that it has entertained the conception of which we speak. In the effort to entertain it, we proceed step beyond step – we fancy point still beyond point; and so long as we continue the effort, it may be said, in fact, that we are tending to the formation of the idea designed; while the strength of the impression that we actually form or have formed it, is in the ratio of the period during which we keep up the mental endeavor. But it is in the act of discontinuing the endeavor – of fulfilling (as we think) the idea – of putting the finishing stroke (as we suppose) to the conception – that we overthrow at once the whole fabric of our fancy by resting upon some one ultimate and therefore definite point. This fact, however, we fail to perceive, on account of the absolute coincidence, in time, between the settling down upon the ultimate point and the act of cessation in thinking. – In attempting, on the other hand, to frame the idea of a limited space, we merely converse the processes which involve the impossibility.
We believe in a God. We may or may not believe in finite or in infinite space; but our belief, in such cases, is more properly designated as faith, and is a matter quite distinct from that belief proper – from that intellectual belief – which presupposes the mental conception.
The fact is, that, upon the enunciation of any one of that class of terms to which ‘Infinity’ belongs – the class representing thoughts of thought – he who has a right to say that he thinks at all, feels himself called on, not to entertain a conception, but simply to direct his mental vision toward some given point, in the intellectual firmament, where lies a nebula never to be solved. To solve it, indeed, he makes no effort; for with a rapid instinct he comprehends, not only the impossibility, but, as regards all human purposes, the inessentiality, of its solution. He perceives that the Deity has not designed it to be solved. He sees, at once, that it lies out of the brain of man, and even how, if not exactly why, it lies out of it. There are people, I am aware, who, busying themselves in attempts at the unattainable, acquire very easily, by dint of the jargon they emit, among those thinkers-that-they-think with whom darkness and depth are synonymous, a kind of cuttle-fish reputation for profundity; but the finest quality of Thought is its self-cognizance; and, with some little equivocation, it may be said that no fog of the mind can well be greater than that which, extending to the very boundaries of the mental domain, shuts out even these boundaries themselves from comprehension.
It will now be understood that, in using the phrase, ‘Infinity of Space’, I make no call upon the reader to entertain the impossible conception of an absolute infinity. I refer simply to the ‘utmost conceivable expanse’ of space – a shadowy and fluctuating domain, now shrinking, now swelling, with the vacillating energies of the imagination.
Hitherto, the Universe of Stars has always been considered as coincident with the Universe proper, as I have defined it in the commencement of this Discourse. It has been always either directly or indirectly assumed – at least since the dawn of intelligible Astronomy – that, were it possible for us to attain any given point in space, we should still find, on all sides of us, an interminable succession of stars. This was the untenable idea of Pascal15 when making perhaps the most successful attempt ever made, at periphrasing the conception for which we struggle in the word ‘Universe’. ‘It is a sphere,’ he says, ‘of which the centre is everywhere, the circumference, nowhere.’ But although this intended definition is, in fact, no definition of the Universe of Stars, we may accept it, with some mental reservation, as a definition (rigorous enough for all practical purposes) of the Universe proper – that is to say, of the Universe of space. This latter, then, let us regard as ‘a sphere of which the centre is everywhere, the circumference nowhere’. In fact, while we find it impossible to fancy an end to space, we have no difficulty in picturing to ourselves any one of an infinity of beginnin
