I'd like to share this playlist, though it probably deserves a thread of its own apart from my notion that you are never truly sober or sane, it will help support the claims I am making
1. Introduction to Human Behavioral Biology - YouTube
This is a lecture on Human Behavioral Biology and could possibly contain the most useful information you have ever encountered. I recommend this lecture to all Humans who wish to understand Humans.
But back to my point. We consider our ego to be the controller of our being. We consider ourselves to be rational thinkers. We consider ourselves to be our personality at all times.
Worse yet, we consider other people around us in a very two dimensional way. We take our impression of them and construct their personality in our heads. Even though it cannot possibly be accurate, we accept this personality we constructed as fact. Only when we get to know someone do we account for changes in mood.
And we often consider our mood to have a rational cause, we get angry when something pisses us off, we get sad when something beckons our sympathy. While there is typically an external cause (or justification) for the reaction, our actual mood is based upon chemical reactions in the body which is heavily dependent upon our diets and lifestyles.
For example, sexual attraction shuts off part of the male brain and limits their capacity for rational thought. This inebriation is most profound in the face of drugs and hot chicks but we are constantly being subtly inebriated or irrationally influenced by our habits and diet. Eating a lot of high creatine foods would make you into a different person with a different personality than eating a lot of complex carbohydrates. Drinking sugary beverages or even just the amount of water you've had to drink that day influences your personality
The first example highlighted in the lecture is about a mutation in the brain which would cause a normally rational person to exercise irrational behavior such as punching some work colleague in the face or having an affair with a 16 year old girl. Rationally speaking, it's not very intelligent to get yourself fired from work or screw around behind your wife's back with a minor. But from the standpoint of evolution, this sort of mutation is understandable. We emerged from creatures of violent dominance and sexual promiscuity. It's only reasonable these genes would continue to pop up in order to test the water to see if this may, possibly, be a more viable method.
Consider the peppered moths of industrialized London. Before the turn of the century most peppered moths were light gray but there was an occasional darker colored moth. The light gray color enabled them to blend in with the lichen that grew on the trees. After coal production boomed, a black film covered the trees and killed off the lichen, thus enabling the darker moths which used to stand out more to conceal themselves better and within a few generation the peppered moth population had turned to a much darker color. Nonetheless, there are still plenty of light gray ones. These guys are usually easier prey but perhaps when the lichen grows back they will become the most suitable variation again.
In much the same way, behavior which we may consider to be completely nonviable resurfaces occasionally to enable humans to adapt more quickly to changing circumstances. Sanity and soberness could be defined as nothing more than the most viable behavior at the time, if it can be defined at all.
