Consciousness and Free Will

There is another video on YouTube entitled: “Free will is scientifically impossible.” My objection to this is: if there were no free will, if we were doomed to be mere spectators of events that unfold deterministically, why do we have consciousness at all? Consciousness must have evolved (or access to consciousness, if, like me, you consider the psyche to be something immaterial). What survival advantage would living beings with consciousness have if they were unable to make decisions?  Claus D. Volko 

What place do humans have in a world with artificial intelligence?

Yuval Noah Harari posed this question in his lecture at: https://www.youtube.com/watch?v=oJB7JNWo58w In my opinion, human society is a phenomenon that has developed over thousands of years because humans were not alone and were therefore forced to find an order that enabled them to live together in a regulated manner. It has proven successful for every person to earn their own living and to serve other people as employees. If many people are no longer needed in the work process because artificial intelligence and robots can do what they do at least as well and are also cheaper, humanity will have to find another basis for peaceful coexistence. These are enormous challenges. We really need to think about this. The final word is far from being spoken. There will be various models that will offer themselves as solutions. Perhaps different approaches will prevail in different countries. In any case, we are living in exciting times. Claus D. Volko 

Severe mental disorders, hormones and the immune system: A Review

The following text, generated by ChatGPT, is a structured synthesis of the relationship between severe mental disorders (SMD), hormones, and the immune system , integrating Dr. Uwe Rohr’s work with subsequent and newer research in psychoneuroimmunology and psychoneuroimmunoendocrinology.  1. Core idea in Dr. Uwe Rohr’s research Dr. Uwe Rohr approached severe mental disorders (e.g. major depression, bipolar disorder, schizophrenia, PTSD) not primarily as isolated “brain diseases”, but as systemic disorders of stress regulation , involving endocrine and immune dysregulation . 1.1 Stress as the central trigger Building on Selye’s stress concept, Rohr emphasized that chronic or extreme stress is the common denominator in SMD. Stress activates the hypothalamic–pituitary–adrenal (HPA) axis , leading to altered ACTH and cortisol signaling . 1.2 Steroidal hormone cascade model Rohr proposed that stress does not only elevate cortisol but distorts the entire steroid hormone cascade...
