Why be good?

[henryp]

Indeed, there are no objective moral values, as has been explained at length earlier.

I don't mean to toot my own trumpet, but I'll put myself under the microscope as an example. I want to die, I'm utterly sick of life and how ill I am and I've wanted to die for about 8 years now. They only reason I don't kill myself is because of how it would devastate my wife. So I'm choosing to carry on living for an entirely selfless purpose, which I get nothing out of personally except knowing I make my wife happy. If I only cared about myself and what was good for me, I'd be off to do myself in right now. I don't do it for any big reward at the end, or because I'm scared of being punished if I kill myself. I do it because I care more about my wife's happiness than my own.

This is an interesting riddle of death that I haven't wrapped my brain around yet.  I worry about what happens to my loved ones if I die while I'm alive.  But if I die, I won't be worrying about what happens to my loved ones.  So I only care about what happens in a future timeframe up until the timeframe starts, at which point I no longer care.

This is fair. The key point I'm making is that Me > Not me for a vast majority of not me's.

You seem to be ignoring our evolutionary past in your calculation. 

When our ancestors lived in small groups or 50-150 (most of our history), there was a bit more emphasis on altruism, reciprocity, kin selection. And every member knew everyone else.

A member of a group, while their own survival was paramount to them, they could not get away with treating the other members of the group as if they did not matter. If so, they risked being ejected from the group. Which would mean almost certain death. We are a social species after all.

Those evolutionary traits are part of our nature. They are driving force that causes us to be moral agents. 

Here's the trick.  I consciously know that a lot of things are a result of me being programmed to do things that are not in my best interest because of some survival need from 50 million years ago.  So I can just say "Fuck that nonsense" and ignore it if I don't find it to be rational.  And in many cases, I can completely purge it from my system when the remnants of my old-timey evolutionary impulse are weak enough/stupid enough.

What I imagine is happening for everyone, and explains the huge gap from theoretical "Let's all be good" and what we actually see, is that such ideas have been subconsciously weighted way lower as time has moved on.  

Consequence being, Omaha can get crushed by a tornado, and I can not care even a little.  I can not be afraid walking into a dark room.  I can do a number of things that my evolutionary impulses say not to..  The rational part of my brain is able to trump stupid stuff time and time again.  And that's why I am unmoved by the evolutionary motivations of ape-men.
