“In order to determine what is and isn’t reasonable, we not only take account of the values of external things, but each of us also takes his role into consideration.
For one person it’s reasonable to fetch someone else’s chamber pot, because he’s focused on the fact that, if he doesn’t do it, he’ll be flogged and denied food, while, if he does, nothing unpleasant or painful will happen to him.
But another person not only considers it unbearable to do that but can’t stand even the idea of someone else’s doing it.
So if you ask me, ‘Should I or shouldn’t I fetch the chamber pot?’ I’ll reply that being fed is preferable to being denied food, and that being thrashed is less preferable than not being thrashed, and that therefore, if these are the criteria by which you measure what’s in your interest, you should go and fetch it.
‘But that’s not the kind of person I am.’ That’s something for you, not me, to take into account in your deliberations. After all, you’re the one who knows himself, which is to say you know how much you’re worth to yourself and at what price you sell yourself. For different people sell themselves at different prices.” (Discourses, I.2.7-11)
