Meditations 12.30

There is one light of the sun, though it is interrupted by walls, mountains, and other things infinite. There is one common substance, 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.

Marcus Aurelius, Meditations 12.30, translated by George Long

There is one Light of the Sun, even though its continuity be broken by walls, mountains, and countless other things. There is one common Substance, even though it be broken up into countless bodies individually characterized. There is one Soul, though it be broken up among countless natures and by individual limitations. There is one Intelligent Soul, though it seem to be divided. Of the things mentioned, however, all the other parts, such as Breath, are the material Substratum of things, devoid of sensation and the ties of mutual affinity—yet even they are knit together by the faculty of intelligence and the gravitation which draws them together. But the mind is peculiarly impelled towards what is akin to it, and coalesces with it, and there is no break in the feeling of social fellowship.

Marcus Aurelius, Meditations 12.30, translated by C. R. Haines
