 Admittedly some external things are more natural to us than others, just as it is natural for a foot, considered solely for itself, to be clean rather than muddy, and for an ear of grain to continue growing rather than being cut. But this is only when we consider ourselves in isolation rather than as parts of a larger whole. As Chrysippus says, the foot if it had a mind would welcome becoming muddy for the sake of the whole (2.6.11). Even one’s own death is of no particular concern if that is what the orderly workings of the universe require.
