"It's possible to understand what nature wants from situations where we're no different from other people. For example, when a slave breaks someone else's cup we're instantly ready to say 'These things happen.' So when it's a cup of yours that gets broken, appreciate that you have the same attitude as when it's someone else's cup. Transfer the principle to things of greater importance. Has someone else's child or wife died? There's no one who wouldn't say 'So it goes.' But when it's one's own child or wife who's died, the automatic response is 'Oh, no!' and 'Poor me!' It's essential to remember how we feel when we hear of this happening to others."
There are a few (darkly) funny claims in here:
- _ANYONE_ would be pretty indifferent to hear that someone's wife or child has died.
- You should feel the same about your wife or child as someone else's.
- Potentially, you should feel the same way about your wife as you do a cup.
I'm being cheeky with the last one, and I don't think there's _nothing_ to the quote above, however I cannot imagine most people being able to adopt this view, or seeing it as a view which _should_ be adopted.
