Human nature is a very rugged thing that grew up in jungles and is sequenced by drives that encourage people to eat and fuck. We like to believe there’s more to it, but there is not. The most valuable trait in the jungle was physical strength and the mastery one had over ones body.
When we started building societies our needs began to take second place to the needs of our group. The most valuable traits began to move away from brute force and towards leadership. The leader of a tribe would be given authority over the warriors in order to best use their strength to help the group.
As societies became more complex and harder to manage we began to set rules in which our leaders would have to abide by, which we call Laws. At this stage physical strength was mostly used by leaders to impose these laws upon people in the form of military and police systems.
Leaders use force in order to enforce laws.
In the beginning of building cultures the most effective force was physical force, but as societies grew cultural engineers learned that brute force is only meekly effective compared to psychological force.
Morality is the system of ideas a society uses to tell its members which behaviors are acceptable to do. All acceptable behaviors that make managing a society easy are labelled good or legal, where as all unacceptable behaviors that make managing a society difficult are labelled as immoral or illegal.
Human instincts like the desire for power are labelled as immoral, and any members of a society who display these traits are psychologically punished by all of the societies members by using an emotion: Shame.
This technique of using emotions to control people is known as social conditioning. If you live in the West you more than likely have been socially conditioned using a weapon called shame.
The question is how to break free from shame?
Stop believing it.
