Brains
The brain is the source of consciousness. The notion of mind-body dualism is rejected by materialism. It follows that free will does not exist and all of our actions are deterministic.
Understanding the basic functions of the brain should be a necessary prerequisite for life in modern society. Since we are nothing more than self-aware brains, we should be aware of how the brain creates the self. This section will attempt to provide a general summary of the most important aspects of neurophysiology and psychology needed to understand the mind/body relationship and how feedback from our environment shapes our thoughts and behavior.
Neural Networks
The brain is a very complex neural network. Understanding how a simple neural network functions is the most important prerequisite to understanding the brain. The functions are identical, just on a much larger scale.
[Large Language Models in AI, a topic currently in the zeitgeist, are likewise based on neural networks.
