Thinking and information processing, conscious or otherwise, has casual <br>
power through its information content. This is a direct application of <br>
the Laundauer's principle. Mental causation is exactly how Maxwell's <br>
Demon works. It uses it knowledge of the positions and momentum of all <br>
the individual particles of gas to create a temperature gradient. <br>
Maxwell's Demon seems to violate the 2nd law of thermodynamics by <br>
decreasing the entropy of the gas. But, this is not the case, because in <br>
the process of memorizing the positions and momenta of every particle in <br>
the gas and enabling it to increase the system's potential energy, the <br>
Demon increased the entropy or information content of its own brain or <br>
data storage. This could only have been done by erasing whatever <br>
information was there before and incurring some minimal energy cost <br>
given by the Landauer principle E >= k * T * ln2 with k being the <br>
Boltzmann constant and T being Kelven temperature.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">To be clear, are you equating the causal potency of information, with it's necessary generation/storage always incurring a cost of increasing entropy elsewhere?

<br>
Our will directly intervenes in physics, not miraculously, but through <br>
the mathematical connection between information, entropy, and energy. We <br>
areĀ giant Maxwell's demons made possible by smaller Maxwell's demons <br>
called cells, which are made possible by smaller Maxwell's demons called <br>

Yes, but while consciousness or agency are examples of downward <br>
causation or what you call strange loops, these causal loops are far <br>
more general of a phenomenon than consciousness or agency. </blockquote></div></div><div dir="auto"><br></div><div dir="auto">I agree with this.
