UNITS



  1. Human Nature

    1. Postmodernists deny nature, almost a ban on using the word "nature"

      1. Kojeve

      2. Extreme: Rorty denies truth

    2. People assume that if you believe in human nature, you must be right wing. That's wrong.

      1. Don't cede nature to the right 

        1. Especially now, when the environmental movement is so important

      2. Doesn't make sense

      3. It makes it look like you're scared, like you don't want to deal with facts

      4. I'm not afraid of the concept of nature because I think left wing politics is perfectly compatible with nature

      5. In fact, Karl Marx believed in human nature, as did Bakunin and Noam Chomsky.

    3. On the other hand, "Natural Law" theorists are also wrong

      1. Generally using a faulty concept of nature to justify their own prejudices and their own political and ideological agendas

      2. Human nature is not fixed; Nature is not eternal

  2. What is nature?

    1. What isn't nature:

      1. No "great chain of being"; no hierarchy

        1. No creature living today is "more evolved" than any other

        2. We've all been evolving for the same amount of time

          1. You are not more evolved than a worm.  Humans and ladybugs have spent the same number of hundreds of millions of years evolving to survive in your own niche

          2. Of course, they weren't humans and ladybugs that whole time

        3. Some creatures are more evolutionarily stable than others

          1. In a way, you could say that a horseshoe crab is more evolved than a human

      2. Natural does not mean "good"

      3. Natural does not mean "healthy" (death is just as much a part of nature as life)

      4. Nature does not protect us

      5. Nature is not something in the past

        1. "state of nature"

          1. Hobbes

          2. Rousseau

      6. Nature is now 

      7. Nature never draws a line without blurring it.”

    2. Everything is nature (everything is the environment/ecological)

      1. The universe is nature

        1. People think of grass and trees and bunnies

          1. Yes, but also desert and magma

          2. And the liquid metallic hydrogen deep in the planet Jupiter, and the Bose-Einstein condensates in neutron stars

      2. Nature is reality; nature is truth*

        1. More accurately, nature is a way of looking at the universe

        2. Everything humans do is natural

          1. Kinsey

      3. Everything that ever was, was part of nature; everything that ever will be, will be part of nature

        1. Not only all of the past, not only all the present, not only the future that will happen, but every possibility that could possibly happen - it's all nature

      4. Insurance and dry cleaning and plastic six pack can rings and nuclear bombs are all part of nature

        1. Again, that doesn't mean that they're good, or good for you

      5. Rather than thinking of nature as something in the past, I tend to err in the other direction: we are now more "natural" than we ever were before

        1. We are "becoming" natural

        2. And in the future we will be even more natural than we are now

        3. Nature is revealing itself through us

        4. Everything that humans do is an expression of human nature

    3. Nature is what science attempts to investigate.  Nature is what science tries to learn about.  (i.e. Science looks at everything as if it were natural)

      1. Science "naturalizes"

        1. Yeah, so what?

        2. I think naturalizing is a healthy attitude

          1. Not perfect, but comparatively healthy, a lot of the time

          2. Take, for instance, homosexuality

          3. Naturalizing is a way of looking at the universe that tries not to be judgmental

          4. If something doesn't fit into your worldview, you should change your worldview

          5. "That's funny" - Asimov (but he didn't say it)

      2. Emphasis on "attempts" "tries" - not guaranteed, doesn't always succeed

        1. We don't know everything about human nature

      3. Science is not value free

        1. Science values honesty - and a particular kind of honesty

      4. By the way, I do not claim that science is the only way to truth

        1. Walking out into traffic

        2. My argument on the internet with "willfully obtuse" person

          1. They would say they are being more "honest" by being straightforwardly political

          2. I'm going to try to be neutral - is that "dishonest"?

        3. Not natural vs. artificial

          1. Artificial things are natural

          2. Natural vs. Supernatural

            1. Btw, if we prove that supernatural stuff exists, then it's part of nature

            2. If God exists, he's part of nature

            3. "Nature and nature's God," per Jefferson

        2. change is speeding up

          1. Exponential growth

    5. 2nd Law of Thermodynamics - everything tends toward disorder, homogeny
