My Big Toe is a triology written by Tom Cambell and published in 2003. You can find it for free on google books. Tom is a physicist and consciousness researcher for over 50 years. The big question is `What is the nature of our reality`? What are we? Who are we? Why are we? Where do we come from? Does it matter? In our daily life's? I can give you that answer right now, yes, it does!!!

His Big Toe (Theory Of Everything) is a model of our reality, a model does not mean it is the reality, it is how `we`, Tom in this case, `try` to explane our, the, nature of reality. Consistent logic and as accurate possible. The less assumptions a model has, the better. Tom`s model has only two assumptions, Consciousness exists and Evolution exists. Well, not really assumptions are they? I think it is obvious.

The scientist anno 2022 are still materialists. 

In order to understand MBT (to get it) one has to let go of materialism and determinism and realize that Consciousness is the only thing that is fundamental. That Consciousness is the substrate from which, and upon which, everything else is constructed...and that we live in a Virtual Reality created and run by/for Consciousness! 

After absorbing that, everything gets both simple and elegant!
