(…continued from How Do We Make Decisions?)
As explained in previous post, the right hemisphere can benefit from direct as well as contextual logic processing executed by the left hemisphere, because of which, the process of natural selection has assigned the authority of making decisions to it.
The way assigning authority for decision making to a person makes him an agent for actions taken under such authority, assigning authority for decision making to the right hemisphere makes it an agent for actions taken under such authority (these include all actions driven by your intentions, even like rolling your eyeballs, as you are doing right now).
The agency that emerges out upon executing under such authority is what you call I, me, myself, i.e. the “self”.
The way an agent is responsible for actions executed under its authority, the self is responsible for actions executed under its authority.
Although the agent, i.e. the self, has a physical base (substrate) which resides in the right hemisphere of the brain in the majority of population, its nature is informational, i.e. non-physical.
With such non-physical nature of the self, it seems that our actions, personality, nature, behaviour, character, etc. are driven by something that it is not visible, does not weigh anything, does not smell or occupy space, etc., just like the concept of soul.
As it is intended to optimize survival and reproduction of our body, we use the term self for our body.
