I just looked him up on Wikipedia and my first impression is he was a very original/independent thinker. :)

I came to that view unconsciously at first, before I recognized it explicitly. It never made sense to me to not care about my net impact carrying on after I die, since it is pretty clear I am going to die, and very soon relative to our home the universe.

Caring about the whole planet, and measuring my self-worth based on that, seems like the only sensible response. And it isn't in conflict with being self-interested at all, it really maximizes self-interest objectively speaking.

My impact will be all of me that survives but it will go on subtly for a very very long time! Go me, lol!

Off to Amazon to get Stirner's book.
