From the Big Bang to the origin of humanity

December 22, 2018

This 10-minute history of the universe shows all the amazing things that had to happen in order for the human race—that is, for you and me—to exist.

It’s quite a story.  My question is: Where are we in the story?  Are we near the end?  Or at the beginning?  Or somewhere in the middle?

I grew up reading science fiction, and envisioned the human race spreading out to the planets, then to other solar systems and perhaps other galaxies.  I now realize this can’t be taken for granted, but I also know I don’t have the knowledge to set limits on the future.  If life is a rare event in the universe, could it be the destiny of humanity to spread life beyond its point of origin?

Or are we at the end of the story?  Is it the destiny of the human race to use its intelligence to wipe itself out—through nuclear war, through plague, through runaway global warming or just through loss of the will to live.

Or is the history of civilization is just a blip in the life of a species evolved to be hunter-gatherers?

Anti-intellectualism and questioning of authority

Anti-intellectualism has long been a strong and deplorable force in American life, but there’s a fine line between anti-intellectualism and questioning authority.

It is not anti-intellectual to refuse to accept someone’s opinion because the person has an advanced degree and speaks in scientific jargon.

I don’t believe credentialed experts who tell me that hydraulic fracturing for natural gas is safe, or that the proposed Trans Pacific Partnership will create jobs, or that it’s necessary to drop bombs on people in Middle Eastern countries for their own good.

I question authority, but I accept legitimate authority.  I don’t elevate my personal feelings to equal standing with scientific fact, and I don’t think I can determine everything for myself.  Rather I try to figure out which persons have real knowledge and wisdom, based on their records and on my ability to follow their reasoning.
