Starting from a molecule on up, to cells and beyond, at what system level is a being actually making a decision rather than reacting to their chemical environment based on purely chemical laws? For example, the molecules in a cells are solely reacting to their environment based on chemical fundamentals. However, a person thinks things through and makes decisions. Where in that range do we see decisions start to emerge?
Abandon the philosopical concept of an independent thinking mind capable of evaluating something by itself.
“Decisions” and “Thoughts” don’t exist without the environment, as they’re a succession of neuronal activation cascades in response to the current state of all stimulus, the previous connections formed in your brain, and reinforced patterns.
Leave a human being in an empty void and their thoughts will be built by severely boosting sensitivity and then responding to random sensory noise. Sever all sensory connections and the mind shuts down.
