When a mother is stressed while pregnant. Because of war or famine or other hardship, the chemicals produced that the unborn and growing human swims in, change that human.
This new human will grow up quickly, will be focused on material goods. Will develop sexually far earlier. After all, the body knows its a stressful environment and we better procreate as fast as possible.
A new human grown in the womb of a mother who is not stressed and is loved and cared for develops a completely different set of "human nature". They mature slower, sexually speaking. Or, "taking their time" as it were.
They are far more sharing, far less aggressive then their counterparts who were created in a far harsher environment.
We also do not live long enough.
If we lived about 150 years, we would notice the cycles. Like the cycle of war. We would see it coming back around and say, "Been there, Done that, i am not participating in the war again". But since we only live about 60 years (before being planted or put into a "care" facility to never be seen again) we do not see the cycle repeating. We are hit broadside by it.
In the future, there will be no war because the average person will have a long enough time scale to see it repeating and not get involved.
This also ties together with being born from a mother who was not stressed.
And then there is the thought structures you are raised with.
You support war
I know most of you in this community state you are violently opposed to war, but you talk of war all the time.
The way our laws work.
The way our police work.
The ways our law enforcement works.
The way our property system works. (especially property taxes)
The Paris Climate Accord is entirely a WAR package. Designed to bring low level, continuous war to the world.
Communism (as a govern-cement) is a war system. It is not about sharing, it is about taking, and taking, and taking the most important thing from humans, the drive to succeed and improve.
All of these were taught to us.
War is the basis of our schooling system.
So, what we think of as human nature, is in a large part taught to us by the system that is so pervasive and all encompassing; War is the water in which we swim.
It is not human nature.
So, as we slowly peel off these layers of govern-cement control
and start to practice things like peaceful parenting.
When we actually start to work on things such as people care (instead of discarding those who can't compete into the alleys and gutters)
Then we will see a very different "human nature".
And we will look back at the philosophy and study of human nature as being really, really ignorant.
All i can say is that what we call "human nature" is not anything close to human nature.
