UNITS
Human Nature
Postmodernists deny nature, almost a ban on using the word "nature"
Kojeve
Extreme: Rorty denies truth
People assume that if you believe in human nature, you must be right wing. That's wrong.
Don't cede nature to the right
Especially now, when the environmental movement is so important
Doesn't make sense
It makes it look like you're scared, like you don't want to deal with facts
I'm not afraid of the concept of nature because I think left wing politics is perfectly compatible with nature
In fact, Karl Marx believed in human nature, as did Bakunin and Noam Chomsky.
On the other hand, "Natural Law" theorists are also wrong
Generally using a faulty concept of nature to justify their own prejudices and their own political and ideological agendas
Human nature is not fixed; Nature is not eternal
What is nature?
What isn't nature:
No "great chain of being"; no hierarchy
No creature living today is "more evolved" than any other
We've all been evolving for the same amount of time
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
Of course, they weren't humans and ladybugs that whole time
Some creatures are more evolutionarily stable than others
In a way, you could say that a horseshoe crab is more evolved than a human
Natural does not mean "good"
Natural does not mean "healthy" (death is just as much a part of nature as life)
Nature does not protect us
Nature is not something in the past
"state of nature"
Hobbes
Rousseau
Nature is now
“Nature never draws a line without blurring it.”
Everything is nature (everything is the environment/ecological)
The universe is nature
People think of grass and trees and bunnies
Yes, but also desert and magma
And the liquid metallic hydrogen deep in the planet Jupiter, and the Bose-Einstein condensates in neutron stars
Nature is reality; nature is truth*
More accurately, nature is a way of looking at the universe
Everything humans do is natural
Kinsey
Everything that ever was, was part of nature; everything that ever will be, will be part of nature
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
Insurance and dry cleaning and plastic six pack can rings and nuclear bombs are all part of nature
Again, that doesn't mean that they're good, or good for you
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
We are "becoming" natural
And in the future we will be even more natural than we are now
Nature is revealing itself through us
Everything that humans do is an expression of human nature
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)
Science "naturalizes"
Yeah, so what?
I think naturalizing is a healthy attitude
Not perfect, but comparatively healthy, a lot of the time
Take, for instance, homosexuality
Naturalizing is a way of looking at the universe that tries not to be judgmental
If something doesn't fit into your worldview, you should change your worldview
"That's funny" - Asimov (but he didn't say it)
Emphasis on "attempts" "tries" - not guaranteed, doesn't always succeed
We don't know everything about human nature
Science is not value free
Science values honesty - and a particular kind of honesty
By the way, I do not claim that science is the only way to truth
Walking out into traffic
My argument on the internet with "willfully obtuse" person
They would say they are being more "honest" by being straightforwardly political
I'm going to try to be neutral - is that "dishonest"?
Not natural vs. artificial
Artificial things are natural
Natural vs. Supernatural
Btw, if we prove that supernatural stuff exists, then it's part of nature
If God exists, he's part of nature
"Nature and nature's God," per Jefferson
Nature is change/adaptation/evolution
"Life finds a way"
even change is changing
Change is slowing down
Caring for sick, old, hungry
change is speeding up
Exponential growth
2nd Law of Thermodynamics - everything tends toward disorder, homogeny
Another way of saying this is energy, potential
Heat death of the universe

Not enough
Not only empathy but accurate empathy
Don't assume you understand someone else
You can't read minds
"Dark empaths"
I don't regard empathy as inherently moral; nor do I see empathy as exclusively or primarily a tool for manipulation. Rather, I see empathy, per se, as morally neutral. It's a tool, a system of perception. It depends how you use it.

I suspect it worked reflexively. At first, disease and other problems were blamed on rival tribes. Then people began to offer services of protecting from black magic - then, eventually offensive magic.

Bronze Age begins
The earliest piece of bronze is from 4650 BCE, and there have been other early pieces found in Serbia and Bulgaria.
But bronze did not become widespread until about 3300 BCE, when humans started making bronze in Mesopotamia - this is usually cited as the beginning of the "Bronze Age"
“Civilization”
Could earlier civilizations have risen and fallen?
Writing, the State, and Money
These are intertwined in a complex way. Can we untangle them?
The State (government?)
Up until now there has been no government
lack of imagination
How did it start?
Why do people fight for their own oppression?
Not an easy question
One way of reframing it is how did people learn to betray their own families
The sense of family
A deep sense of loyalty that perhaps cannot be put into words
You do anything for family
You sacrifice everything for family, even your own life
Maybe all these fancy theories of “rational maximizers” don't understand that
How did this break down?
Antigone
One obvious answer: war. Soldiers defeat them. Conquered
This isn't enough.
Another answer: religion
This isn't enough.
Another answer: debt adjudication, debt relief

Julian Jayne's theory of consciousness
I love kooks because they simultaneously open our minds to possibilities we had not yet considered and because they allow you to put your own thoughts in sharpest contrast to their thoughts, which gives you the chance to articulate your own position more clearly
