Things not under our control the Stoics placed into a category that they called indifferents. The term indifferent can be misleading and often gives rise to the stereotype of the Stoic who is unfeeling and completely unfazed by the unfolding of surrounding events (which suggests something more like unhealthy denial or repression). It can also suggest, wrongly, that for the Stoic, those things out of our control are simply cast aside carelessly. The indifferents, while they do not possess ultimate significance, are still treated as important responsibilities for the Stoic (to do otherwise would suggest more the attitude of the Cynic instead).
But the Stoic’s relation to the indifferents is not merely a matter of indifference, ignorance, denial or carelessness. Viewed positively, the proper Stoic attitude is to accept all indifferents equally, and letting them all go just as equally—each in its due time, ‘according to Nature,’ as the Stoic saying goes:
The Universe too loves to create what is to be. Therefore I say to the Universe: ‘Your love is mine.’
–Marcus Aurelius, Meditations, Book X.21
The Stoic knows the indifferents are not of ultimate significance because virtue does not depend on those things out of our control. Understanding the proper placement of the indifferents, however, is significant. Virtue does not arise in a vacuum but rather results from the Stoic properly relating to the things under our control and those things not under our control. Virtue then is the result of a certain philosophical engagement with the world, and in this process, one discovers her own role to play in the Whole. This engagement is a dynamic process, since the world likewise is in continual flux—and so one’s role in relation to the Whole may change from one moment to the next.
With this understanding of the indifferents in mind, I’d like to turn to one indifferent in particular: death. The existential realisation of one’s own mortality is a crucial first step in philosophia. It is often said in Stoicism that one should ‘live each day as if it were your last.’ Such an attitude toward mortality is a useful means in cultivation of virtue:
Don’t live as though you were going to live a myriad years. Fate is hanging over your head; while you have life, while you may, become good.
–Marcus Aurelius, Meditations, VI.17
Without the realisation of one’s own mortality, why would anyone even bother with philosophia? And yet there are many people who fear death and do not live each as if it were their last:
Our confidence ought, therefore, to be turned toward death, and our caution toward the fear of death; whereas we do just the opposite—in the face of death we turn to flight, but about the formation of a judgement on death we show carelessness, disregard, and unconcern.
–Epictetus, Discourses, Book II.1
The existential realisation of one’s own mortality simply puts all things into proper perspective, with the aim of focusing the individual’s cultivation of virtue, which only takes place in the present moment:
Even were you about to live three thousand years or thrice ten thousand, nevertheless remember this, that no one loses any other life than this which he is living, nor lives any other than this which he is losing. Thus the longest and the shortest come to the same thing. For the present is equal for all, and what is passing is therefore equal: thus what is being lost is proved to be barely a moment. For a man could lose neither past nor future; how could one rob him of what he has not got?
–Marcus Aurelius, Meditations, Book II.14
