[A] "Seen even with the eyes." It is supposed that this may be explained by the Stoic doctrine, that the universe is a god or living being (iv. 40), and that the celestial bodies are gods (viii. 19). But the emperor may mean that we know that the gods exist, as he afterwards states it, because we see what they do; as we know that man has intellectual powers, because we see what he does, and in no other way do we know it. This passage then will agree with the passage in the Epistle to the Romans (i. _v_. 20), and with the Epistle to the Colossians (i. _v_. 15), in which Jesus Christ is named "the image of the invisible god;" and with the passage in the Gospel of St. John (xiv. _v_. 9). Gataker, whose notes are a wonderful collection of learning, and all of it sound and good, quotes a passage of Calvin which is founded on St. Paul's language (Rom. i. _v_. 20): "God by creating the universe [or world, mundum], being himself invisible, has presented himself to our eyes conspicuously in a certain visible form." He also quotes Seneca (De Benef. iv. c. 8): "Quocunque te flexeris, ibi illum videbis occurrentem tibi: nihil ab illo vacat, opus suum ipse implet." Compare also Cicero, De Senectute (c. 22), Xenophon's Cyropaedia (viii. 7), and Mem. iv. 3; also Epictetus, i. 6, de Providentia. I think that my interpretation of Antoninus is right. 29. The safety of life is this, to examine everything all through, what it is itself, that is its material, what the formal part; with all thy soul to do justice and to say the truth. What remains, except to enjoy life by joining one good thing to another so as not to leave even the smallest intervals between? 30. There is one light of the sun, though it is interrupted by walls, mountains, and other things infinite. There is one common substance,[A] though it is distributed among countless bodies which have their several qualities. There is one soul, though it is distributed among infinite natures and individual circumscriptions [or individuals]. There is one intelligent soul, though it seems to be divided. Now in the things which have been mentioned, all the other parts, such as those which are air and matter, are without sensation and have no fellowship: and yet even these parts the intelligent principle holds together and the gravitation towards the same. But intellect in a peculiar manner tends to that which is of the same kin, and combines with it, and the feeling for communion is not interrupted. [A] iv. 40.
