the author laments the hubris and arrogance present in all societies, as if these exaggerations were bugs, and not features.
the arrogance of the leaders and the peddling of hope are there because we are all afraid, and nobody wants to admit it. he talks about the chasm of human reality and how you get burned if you get closed to it, and i agree - it makes sense. i came out burned. i was mad at the world for a while and wanted to tear the whole thing down, but i went back for a closer look because i figured there must have been something i'm missing. there is beauty at the bottom of it, and we can get through it.
there is still new land to be explored - we just can't get there by walking or sailing. the ENTIRE GALAXY awaits us if we can just get off this damned rock. let's peddle all the hope we need and beat our chests all day long; let's spread the gospel to heathen civilizations on other planets if that's what it takes for us to move out of this place and into another one. maybe we're just delaying the inevitable and the end of the galactic civilization will be that much more spectacular when it comes, but it's not as if we can go back in time to change all the "best guesses" our world was built on and the gentle lies that sustain it.
we are now heathens living on easter island. we know our civilization is built on a lie. we can either stop telling that lie and kill each other out of anger over mistakes our ancestors made doing the best they could, or we could all keep telling the lie, keep playing our assigned parts with a wink and a nod, and put fewer resources into enforcing what everybody knows is a sham story, and devote all our efforts into finding the new land we think might be out there over the great waters.
the only way through is forward. the only way out is up.
