We are built to interface
For the sake of argument, let us assume the following: firstly, your ‘soul’ is defined as the extant reality and/or presence of your consciousness and mental faculty endemic to the human-being (rational thought); secondly, the mental faculties not endemic to the human-being (such as desire for comfort, avoidance of pain, and instincts to eat, drink, and procreate) are the product of the body and not the rational being.You are a rational being. You inhabit a body. Your rational being inherently desires to interface with other rational beings. Your body is the singular mode in which you can interface with other rational beings; your body is your interface. Speech is an extension of the rational being through the body; speech is an extension of your interface.
Your body has its own desire to interface with other bodies, and this desire is separate from and not related to the desire of the rational being to interface with other rational beings. Chemicals inside your brain (body) such as serotonin, dopamine, cortisol, estrogen, and testosterone all mix together inside your body to form a concoction of emotion that many people confuse with the soul. Your chemical emotions are not an extension of your rational being; animals possess chemical emotion. Your desire to interface with other bodies by mode of sexual intercourse is not your soul/an extension of your rational being; animals possess this desire.Your consciousness has a desire to expand upon itself, often through interface with other forms of consciousness (other people). This desire to expand upon itself can also be partially fulfilled through the acquisition of knowledge. When this desire is fulfilled through a combination of knowledge and socialization, you become self-actualized (or, at the very least, closer to self-actualized).
The human is built around the concept of the interface. Every small ecstasy in our environment — perception of the extant reality of beauty in any form whatsoever — is interfacing with our environment through the body.Why is the human-being designed to interface? For what purpose, and with what intent? The human-being is a social animal. Our rational being is inherently tied to our body; as the body matures, the logical being matures. This is evident in the fact that babies possess a lower faculty in rational-thought and arguably a lower level of self-awareness (consciousness) than an adult.
We possess individual-intelligence, but also collective-intelligence. Society and culture are emergent properties of that collective-intelligence.The benefit that an individual rational being gains from interfacing (presumably through social interaction) is shared by both or all members who participate in this interface. Apply the same logic to every such interface that occurs within a collective, and the benefit is shared by the entire collective. We interface not solely for individual-gain, but for collective-gain.
The rational being interfaces for collective gain, but is capable of modes of operation that violate this principle. For example, imagine a person having a heated disagreement with another person over a political or social opinion. While the ideal mode of operation in this form of disagreement is to simply discuss your opinion with dispassionate regard for the other person’s viewpoint, the chemicals in our brain (body) make it much easier to bash the other person’s viewpoint or the other person themself. This is disadvantageous to the collective.
