We showed in an earlier chapter that the idea of eternity involves immutability. As motion causes time, in which priority and posteriority are discerned, so the cessation of motion puts a stop to priority and posteriority; and so nothing remains but eternity, which is simultaneously whole. Therefore in his final consummation man attains eternal life, not only in the sense that he lives an immortal life in his soul, for this is a property of the rational soul by its very nature, as was shown above, but also in the sense that he is brought to the perfection of immobility.
