This one deals specifically with psychology.
I believe the continuum of human mental activity should be looked at as a gigantic territory around the immediate consciousness. I call the consciousness, "the watcher." At the far reaches of the territory lies the murky, dark grounds of cognitive bias. This land contains all of the information that the brain does not know, but could know if it decided to make the effort to. Natural laws that a person is affected by but does not know about would go here, such as economics, assuming the person is so uneducated. This ground is the largest and most important part of the psyche, but the least understood. Once a person observes a concept, it becomes a part of his reality, the second step inwards.
A person's reality is bounded on the outside by perception, and on the inside by control. Our realities consist of all those concepts that we perceive to be outside our control. One could decide to take responsibility for a certain aspect of our reality, and so incorporate it into the next stage of our psyche, our identity. The identity is bound by things called pillars. These pillars represent beliefs over what we can and cannot control in our lives. If you believe that you cannot start a business, that you're not cut out to be an entrepreneur, that would be a pillar holding your identity in. They provide sanity to our brains. Given infinite possibility, our brains tend to become paralyzed by choice, the pillars keep us from that paralysis.
Our identities are like a city with districts. Each district is a belief. Our beliefs are what we construct our lives upon. If one of those beliefs happens to be religion, than you will construct a good portion of your life on top of that belief, meeting people through your church, using the values of religion to order your efforts. The neighborhoods in your city are called values. These are the things that you want more of out of life. The people that live in these neighborhoods are called techniques. You apply techniques to get more of what you value in life.
I've been working with this model for the better part of a year now, and if you think about it long enough, it can yield some surprising insights. One thing it states is that the outside world isn't anywhere near as important to the psyche as the inner world. The inner world is that entire continuum I described in the above paragraphs. The outside world is represented by five streams of information coming from your senses. Nothing that your senses tell you would mean anything without that grand inner world. Yet most of us hang our proverbial hats on those poor, often deceiving informants. The wise individual would take far more care to keep his inner garden in order.
It also states that we cannot ever truly know one another. All we can ever do is interpret the streams of information gathered from the senses. Nothing direct about another person's psyche is transmitted directly via the senses. The way in which we react and communicate with one another is ordered largely by instinct and genetics. If you're a guy and you start to talk to a woman, the genetic imperative to mate is going to take over your conversation, assuming the subconscious isn't more interested in survival, in which case those matters will take over. It takes a careful effort of will to control the conversations you have with others. This is why men often have difficult times communicating with women. The genetic imperatives takes over and interactions are confused and conflicted. Nature intended it that way.
Only a few, selected males in a population of people are granted free access to females. The rest of us are controlled by genetics to be providers, sacrificing happiness and sexual satisfaction for the good of the species. It should always be remembered that humans have only had civilization for a tiny fraction of our total time on the planet. For hundreds of thousands of years, we survived in small bands, and the adaptations evolution designed for those tiny bands still rule our social activities, even though the need for them has disappeared.
