The Evolutionary Role of Mental Illness in Humans

Mental illness has long been a subject of great debate and curiosity within the realms of psychology and evolutionary biology. While some ponder the question, “Why does a loving God create a universe where humans have to suffer?” others focus on the empirical and biological aspects of mental health. One important point to clarify is that evolution is not driven by a divine purpose or set goal, but rather by natural processes. This discourse delves into the theories surrounding the evolutionary role of mental illness in humanity, and explores one unique perspective on emotional communication through mental responses.

Understanding Evolution Without Teleology

Evolution is a non-directional process, lacking inherent goals or purposes. A complex nervous system evolved due to countless generations of favorable adaptations. It is a natural consequence of the evolutionary process, and like any complex structure, it is subject to breaking down over time. A complex system that does not break down is not possible, and to imagine so would be attributing goals or purposes to the process of evolution, not a scientifically accurate perspective.

Evolution, Aging, and Mental Health

Humans do not evolve in the traditional sense; rather, we age and our bodies deteriorate over time, leading to various health issues. This fundamental biological reality has implications for mental health as well. The moment human beings started to age, they began to face the challenges of mental health, such as cognitive decline and mental illnesses. While some might interpret these struggles as a result of sin, from a biological perspective, mental illness can be seen as a byproduct of a complex nervous system that is subject to wear and tear over time.

The Presence of Mental Illness in Evolution

Mental illness does not have to play a role in evolution. Traits that do not impede reproduction or survival will continue to exist in a population. For particularly aware social species, such as humans, individuals with disabilities or mental impairments may be protected and supported by family and social bonds. This is seen in many animals, including the Merekats, who care for their sick and wounded members.

A New Theory on Emotional Communication

From a theoretical perspective, an intriguing idea suggests that emotions may have served as an early form of communication among humans. During earlier evolutionary stages when humans lived interdependently and before the development of spoken language, communication was crucial for group survival. My theory posits that emotion was an early communication device, signaling body language, facial expressions, and other changes that could be interpreted by other members as signals to pursue or avoid certain situations.

According to this theory, emotions were designed to ensure that a situation is recognized and acted upon by other members before the feeling passes. This is why humans experience a natural inclination towards closure, recognition, validation, celebration, mourning, and other emotional responses. These responses are not experienced as completely real personal states, but rather as external signals that prompt action or response.

Experiencing Emotions as Communication Signals

The experiment suggested here involves recognizing emotions as communication signals rather than personal experiences. For instance, when you feel hurt, recognize that the feeling is intended to prompt a communication between individuals about inappropriate behavior or lack of contribution to the group's overall survival. Theoretically, a bad feeling should pass quickly once you understand that there is no personal purpose for it.

This experiment encourages individuals to see their emotional responses as part of a broader communication system rather than as a reflection of their personal reality. By doing so, it allows individuals to react to the situation in a constructive manner, aiming for resolution or recognition of the issues without the unnecessary suffering caused by prolonged negative emotions.

Conclusion

In conclusion, the question of mental illness's role in human evolution is complex and multifaceted. While evolution does not have a predetermined goal, it can produce traits and responses that, in certain contexts, may be seen as maladaptive. Viewing emotions as an early form of communication can provide insight into why humans experience certain emotional responses and how they can be harnessed more effectively. This perspective offers a fresh way to understand and potentially mitigate the effects of mental health issues within a social and evolutionary framework.
