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, in accordance 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 Pascal 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 _beginnings_. As our starting-point, then, let us adopt the _Godhead_. Of this Godhead, _in itself_, he alone is not imbecile—he alone is not impious who propounds—nothing. “_Nous ne connaissons rien_,” says the Baron de Bielfeld—“_Nous ne connaissons rien de la nature ou de l’essence de Dieu:—pour savoir ce qu’il est, il faut être Dieu même._”—“We know absolutely _nothing_ of the nature or essence of God:—in order to comprehend what he is, we should have to be God ourselves.” “_We should have to be God ourselves!_”—With a phrase so startling as this yet ringing in my ears, I nevertheless venture to demand if this our present ignorance of the Deity is an ignorance to which the soul is _everlastingly_ condemned.
