Zach, I grew up with Carl Sagan. Grew up on cosmos, followed him
  everywhere he went on TV. He was like a dad when I didn't have a
  dad, and he got me fascinated by science. No, he was no atheist.
  Times were different then * they weren't so black-and-white as
  they are today. He fought against the excesses in religion and
  science and politics * but had no trouble with mainstream
  anything. And one of his famous interviews, he foresaw a future
  religion that's based on science * kind of pantheism that was
  modifiable. So don't put black-and-white as coming out of his
  mouth * because it didn't.

  ===

  today's form of atheism did not exist back then in the 80s. It's
  only through the efforts of Dawkins and those of the new atheist
  movement from the mid to late 90s onwards, that you find the
  kind of radical religious atheism that you find today. I believe
  science has the best opportunity for answers * but please, take
  it down off of its pedestal. I've worked with scientists * at
  pharmaceutical industry for a few years * they do their best *
  but they're human. Don't make a religion out of science *
  scientism has been the worst trend of the past 18 years.

  ===

  I miss the hell out of Carl Sagan ever since he died * between
  him, joseph Campbell, Douglas Adams (who WAS atheist but again,
  not the sort you see today) and george carlin - they shaped my
  worldview * unafraid to see bullshit whatever it lies, and
  campbell fed the Monomyth which allows me to see it even in non
  religious areas, anytime somebody has a hero on a pedestal.

  ===

  You won't find certainty in science * but you will find
  heuristics.

  ===

  People typically associate heuristics with engineering * but
  when it comes down to it, it's the backbone of science as well -
  scientists can sometimes get a little cocky if They get popular.

  ===

  Remember * certainty is a human emotion. We may have codified it
  * but it's still an emotion.

  Oh, that's just theoretical physicists. They don't practice
  science - they practice speculation. If you want real science *
  go to working biologists * or better still, Chemists. I'm not
  talking about the ones with the big mouths, but the ones whose
  work we don't see and whose names we don't know * they have my
  respect.I'm distinguishing between working biologists from
  theoretical biologists * Who do lots of talking but no real
  work.
