That is principally and primarily called immortal, which supplies itself with immortality; since that also is primarily being which is being from itself; intellect which is intellect from itself; and one which is from itself one. For every where that which primarily possesses any thing is such from itself; since if it were not so from itself but from another, that other would be primarily, either intellect, or life, or _the one_, or something else; and either this would be primarily so, or if there is nothing primarily, the ascent will be to infinity. Thus therefore, that is truly immortal, which is immortal from itself, and which imparts to itself immortality. But that which is neither vital according to the whole of itself, nor self-subsistent, nor possesses immortality from itself, is not primarily immortal. Hence as that which is secondarily being is not being, so that which is secondarily immortal is not immortal, yet it is not mortal; for this is entirely a defection or departure from the immortal, neither possessing a connascent life, nor infinite power. For these three are in a successive order: That which possesses from itself infinite life; that which receives infinite life from another; and that which neither from itself nor another exhibits the infinity of life. And the first indeed, is immortal; the second is not immortal; the third is mortal; and the mean is adapted to the mundane Gods. For they neither have the immortal from themselves, so far as they derive it from that which is truly and primarily immortal, and so far as bodies are suspended from them; nor have they a finite life; but they are filled indeed from the eternal Gods, and produce mortal natures. For the second fabrication is connected with the first, proceeds about it, is governed by it, and refers to it the production of the mortal genera. Again, with respect to the indissoluble, that which is principally and primarily so is simple and free from all composition. For where there is no composition what representation can there be of dissolution? But that is secondarily indissoluble, which is indissoluble with a bond; which is at the same time dissoluble in consequence of proceeding from divided causes. For it is not simply dissoluble, but dissoluble by its cause. For that which is bound prior to all time, is alone bound according to cause; but that which is alone causally bound, is alone causally dissolved. And the third from that which is properly indissoluble, is that which was indissoluble for a certain time; because the first indeed, is properly indissoluble in conjunction with simplicity; but the second is subordinately so, together with composition: and the third, falling off from both, is in its own nature dissoluble.
