One ought, moreover, to recognise that it is one thing to look at a matter as it is, and another thing to look at it in the light of reason and thought. In the case of all created things, the distinction of the subsistences is observed in actual fact. For in actual fact Peter is seen to be separate from Paul. But the community and connection and unity are apprehended by reason and thought. For it is by the mind that we perceive that Peter and Paul are of the same nature and have one common nature Greg. Naz., Orat. 37.. For both are living creatures, rational and mortal: and both are flesh, endowed with the spirit of reason and understanding Ibid. 32.. It is, then, by reason that this community of nature is observed. For here indeed the subsistences do not exist one within the other. But each privately and individually, that is to say, in itself, stands quite separate, having very many points that divide it from the other. For they are both separated in space and differ in time, and are divided in thought, and power, and shape, or form, and habit, and temperament and dignity, and pursuits, and all differentiating properties, but above all, in the fact that they do not dwell in one another but are separated. Hence it comes that we can speak of two, three, or many men.
