(I put that "desires that outrun the limits fixed by nature" in red not because it is related to the current topic, but because that seems to me to be a good choice of words to describe something we often struggle with as "neither natural nor necessary" or all sorts of other adjectives." Seems to me that the factor that unites them all is that they "outrun the limits fixed by nature.")
At first blush that sounds quite good, but I'm beginning to wonder if, to some, that might imply a limit that is the same for everybody. With all due respect to Diogenes, would a better phrasing be "desires that outrun the limits fixed by one's nature"?
