My innate “personality traits” and “temperament” (fundamental nature, drives and disposition) affect my brain process (mind, cognition, nurtured nature) and therefore my view of the world and how I respond to my reality. My brain is the part of the body which is the processor for all of my thinking activity (mind), which is not only “how do I feel?” (body) but “how do I feel about something else?” (emotion) And decision-making for action. (thinking, feeling, acting)
The study of this process is called Psychology. To make the study even more complex, each of these traits/types and temperaments have a high/low range of affect based on a situation and the variable state of other traits/types and temperaments and the variableness of the mind-body state. Every Person has a unique personality profile which is revealed in a personality matrix of strong and weak attributes. A good conceptual model of this process is a large sound system keyboard which controls the volume of many frequency ranges by sliding a lever along a scale. (equalizer) The higher the lever the more the effect of that range. To complete the analogy, some levers need to be harder to change than others. In addition to this analogy, time and circumstances try to change everything. To some extent, with insight and intentionality, I can be “running” the sound system. At other times, it is subconscious, spontaneity, time and circumstances (emotional reaction) which try to take control.
The Bible calls this the “soul”, which in Greek is “psuche” and in Hebrew “nephesh”. The Bible has a lot to say about keeping our soul in control by the Spirit. The soul has a natural inclination to take care of the body and an innate inclination to wonder about a supernatural or spiritual relationship. The initial strength of these inclinations may be from my ancestral DNA which makes up my DNA. Many of these inclinations can be controlled and ought to be controlled. The soul would say it is all about me. The Bible says “do unto others as you would have them do to you.”. Kant calls this the “moral law”, a “categorical imperative”. Theologians call it the “golden rule”.
The ‘Golden Rule‘ (in its positive form) says: “Treat others how you wish to be treated”. Kant’s first formulation of his Categorical Imperative says: “Act only in accordance with that maxim through which you can at the same time will that it become a universal law.” https://en.wikipedia.org/wiki/Categorical_imperative
