Apr 27, 2009 of Dilbert discusses Boltzmann Brain Hypothesis
The Boltzmann brain hypothesis states that the brain is a self-aware entity arising due to random fluctuations out of a state of chaos.
Deepak Chopra wrote the following here:
Going to an inner level, brain and muscle cannot do anything without thousands of chemical reactions taking place in every cell each second. These also obey your command to reach for a piece of chocolate. Since cells operate by creating new proteins and enzymes, we can say that you literally create whatever is needed to carry out your desires. There is no gap between what you want and what your body does. (When there is a gap, some disorder or disease process has created damage in the chain of command.) The quantum world, where atoms interact to form the building blocks of life, is open to consciousness.
