I thought the darkest thing you were going to point to was the matter of fact reference to the role of the slave as the inadvertent cup breaker! Some wonderfully insightful thoughts on how to manage one's emotions when confronted by life's challenges, of which I think are worth reading, but taking for granted the other human whose life is not their own and who is treated as (valuable) property by the philosopher is pretty dark to me.

I'm guessing that the institution of slavery was part of the entire imperial project of conquest so even if their conscience was briefly troubled it would've fallen into the 'so it goes' basket. But it does seem strange to the modern reader.
