 When we take the rationality of the world order into consideration, we can begin to understand the Stoic formulations of the goal or end. “Living in agreement with nature” is meant to work at a variety of levels. Since my nature is such that health and wealth are appropriate to me (according to my nature), other things being equal, I ought to choose them. Hence the formulations of the end by later Stoics stress the idea that happiness consists in the rational selection of the things according to nature. But, we must bear in mind an important caveat here. Health and wealth are not the only things which are appropriate to me. So are other rational beings and it would be irrational to choose one thing which is appropriate to me without due consideration of the effect of that choice on other things which are also appropriate to me. This is why the later formulations stress that happiness consists in the rational selection of the things according to nature. But if I am faced with a choice between increasing my wealth (something which is prima facie appropriate to my nature) and preserving someone else’s health (which is something appropriate to something which is appropriate to me, i.e. another rational being), which course of action is the rational one? The Stoic response is that it is the one which is ultimately both natural and rational: that is, the one that, so far as I can tell from my experience with what happens in the course of nature (see Chrysippus’ formula for the end cited above, 63B), is most in agreement with the unfolding of nature’s rational and providential plan. Living in agreement with nature in this sense can even demand that I select things which are not typically appropriate to my nature at all – when that nature is considered in isolation from these particular circumstances. Here Chrysippus’ remark about what his foot would will if it were conscious is apposite.
