But it's in the last 500 and then 50,000 years, notice we're doing an increments of 10. That's kind of interesting. That's five million years ago. And then 50 million ago, 500 million ago, five million and now, 550,000 years ago, by 50,000 years ago, our species was already in the process of differentiated, okay? And then what happens is we, somehow, we get together for collective intelligence and we develop two key lines that are transformative. One is this what we're doing right now, the talking line. And the other thing that we do is we develop complex tools that evolve themselves. So we get complex tools, technology, other animals have simple tools. We build evolving complex tools on the one hand, and then we build evolving talking systems, which I call justification systems, on the other. And as we build these justifications, we're building a mine three on top of our mine one two, and we're creating a collective mine, what I call capital C culture, and the culture person plane of existence, which is the capacity to enter into dialogue with each other and justify our actions on the social stage and be held accountable if you fuck up, okay? And it is this action's pattern, mine three patterning, that is so radically different about human mentation. So human mentation is mine one two, like the rest of the animals, and it's got mine three through a socialization process that gives rise to the self, this is what Renee DeCarpus point out, oh my God, I think therefore I am I'm a self conscious justifier, okay? And ultimately we can trail the pattern of justification, all the trail that is cultures building belief systems, and then unified theory trails that into philosophy, and it trails it into science as a particular kind of justification system. And the picture of the tree of knowledge, which maybe we can put up at some point, is shows matter, life, mind, culture in the world, and then it shows science coming out of culture, and then proposes that the physical science should be mapping matter, the biological sciences should be mapping life, and in fact, that's pretty much the way they do, and it shows that psychology should have been mapping minded animals, and the history of it is very much, there are some psychologists that have long said exactly this point, William James's functionalism is damn close to this, okay? And that there are then the social sciences that are mapping human behavior at the culture person plane. And so what the tree of knowledge does is it gives us a map of the four dimensions of complexification matter, life, mind, and culture, the four domains of science, and gives us a complete loop that places the knower, knowing about the world in relationship to the world where it came from. Okay, and this is what's been missing folks, I mean this big picture structure is what was missing, okay? And what it does is it draws lines in the world, cars, nature at its joints to use a Plato term, and the joint points are energy to matter, that's where the big bang happened, matter to life, that's where everyone knows, oh my God, what's the miracle of life? What's missing is life to minded animals at the Cambrian explosion, and then finally minded animals to culture justifying persons 550,000 years ago, okay? And the explosion of that, and the evolution of justification into things like refined philosophy, and then science, and then ultimately science about factoring out our subjective and social knowledge, and trying to yield a picture, an objective picture of matter and life, and now maybe mind and culture in a completed view. So that's the tree of knowledge system, I'll pause there and see.
