Homeostasis

Yesterday I heard Dr.  Damasio on the mindscape podcast hosted by Prof. Sean Carroll.
https://www.preposterousuniverse.com/podcast/2019/04/29/episode-44-antonio-damasio-on-feelings-thoughts-and-the-evolution-of-humanity/

 It was a fascinating, insightful conversation.

The observation that "feelings" drive culture was new to me. From experience, I can say that feelings, along with thought do drive my choices.

Affect i.e. emotions and feelings play an important role in shaping societies. The hypothesis drawn  is that , homeostasis is a necessary pre-requisite to maintaining life , and homeostatic mechanisms result in feelings as adaptations to the environment.

Nervous systems could have evolved to regulate homeostasis. This is a strong argument from the evolutionary biology point of view, because the questions being asked today are-what are the environmental selection pressures that drive evolution.

Exchange of substances occur between the living organism and the environment to maintain homeostasis. Regulation of this process resulted in the evolution of nervous systems.

The conversation with Dr. Damasio compels me to read his book-"The Strange Order of Things".
