But supposing for a moment that it was impossible to conceive the work, without also conceiving the workman, who watches over his work, where must we place this workman? Shall it be interior or exterior to his production? Is he matter and motion, or is he only space or the vacuum? In all these cases either he would be nothing, or he would be contained in nature: as nature contains only matter and motion, it must be concluded that the agent who moves it is material; that he is corporeal; if this agent be exterior to nature, then we can no longer form any idea of the place which he occupieth: neither can we better conceive an immaterial being; nor the mode in which a spirit without extent can act upon matter from which it is separated. These unknown spaces, which imagination has placed beyond the visible world, can have no existence for a being, who with difficulty sees down to his feet; he cannot paint to his mind any image of the power which inhabit them; but if he is compelled to form some kind of a picture, he must combine at random the fantastical colours which he is ever obliged to draw from the world he inhabits: in this case he will really do no more than reproduce in idea, part or parcels of that which he has actually seen; he will form a whole which perhaps has no existence in nature, but which it will be in vain he strives to distinguish from her; to place out of her bosom. When he shall be ingenuous with himself, When he shall be no longer willing to delude others, he will be obliged to acknowledge, that the portrait he has painted, although in its combination it resembles nothing in the universe, is nevertheless in all its constituent members an exact delineation of that which nature presents to our view. Hobbes in his _Leviathan_ says, "The universe, the whole mass of things, is corporeal, that is to say, body; and hath the dimensions of magnitude, namely, length, breadth, and depth: also every part of body is likewise body, and hath the like dimensions; and consequently every part of the universe is body; and that which is not body, is no part of the universe; and because the universe is all, that which is no part of it is nothing; and consequently no where: nor does it follow from hence, that spirits are nothing, for they have dimensions, and are therefore really bodies; though that name in common speech be given to such bodies only as are visible, or palpable, that is, that have some degree of opacity: but for spirits they call them incorporeal; which is a name of more honour, and may therefore with more piety be attributed to God himself, in whom we consider not what attribute expresseth best his nature, which is incomprehensible; but what best expresseth our desire to honour him."
