If you have a good core, you’re building a decent society with every step you take, every word you write or speak, every action you do.
People have spent their whole lives fighting for causes they knew they’d never see the end result for.
Some causes take multiple lifetimes.
I always wanted a time machine for that reason. I want to see 500 years from now. . I want to see if it’s how I imagine it to be and it’s a positive vision. Then I want to come back and give a report.
I have some disagreements with Pinker (he has a hard-wired view of neurology) but I can’t fault his positivism in the least.
