See, therefore, the third argument after these, leading us to the same conclusion with the former arguments. For it is necessary that the cause of all beings should be that of which all beings participate, to which they refer the subsistence of themselves, and which separates itself from nothing that in any respect whatever is said to have an existence. For this alone is the object of desire to beings, which primarily, or in some other way, is itself the cause of their subsistence. And it is necessary that every thing which is produced with reference to, and on account of it, should have a certain habitude with relation to it, and through this also, a similitude to it. For every habitude of one thing towards another, is predicated in a twofold respect, either from both participating of one thing, which affords to the participants a communion with each other; or from one of them participating of the other; of which, indeed, the one as being more excellent, imparts something to that which is subordinate to itself; but the other, as being inferior, is assimilated to the more excellent nature, so far as it participates of it. Hence it is necessary, if all sensible natures possess a habitude to that which is first, aspire after, and subsist about it, either that there should be a certain third thing the cause of the habitude, or that the principle should impart to the natures posterior to itself, a tendency to itself, and that desire, through which every thing is preserved, and exists. Nothing else, however, is more excellent than that which is first. Hence, the habitude of beings, their existence, and their tendency to the first, are derived from thence. And all things participate of the principle of themselves, if it is necessary that this which is participated, should from thence become apparent in all beings, since it is the principle of all things, and deserts no being whatever. What, therefore, will this nature be, which is every where, and in all beings? Is it life and motion? But there are indeed many things which are deprived of these. Is, therefore, permanency every where, and in all things? But neither is this true. For motion, so far as it is motion, will not participate of permanency. Is much-honoured intellect, therefore, so far as it is intellect, participated by all beings? But this also is impossible. For all beings would have intellectual perception, and no being would be deprived of intellect.
