Roots
X-Logic is about very simple basic principles of thinking and knowing. We consider them elementary. They are to be found everywhere, in every area of life and matter and so.
This may be explained by the fact that all we can know about the world is exactly this: known. Even experience, however direct, is somehow interiorized and so might have passed some sort of filter.
On the other hand, however, it might also be possible that the principles of X-Logic can be found in the mental for the reason that it inherited them, so to speak, from its material roots. These may be searched in structures and functions of the brain, or even deeper, maybe on a so-called “quantum scale”.
Yet generally applicable logical principles do not really have to be based on whatever reasons. Instead, these principles can serve as a basis, for describing and explaining material as well as mental phenomena, for instance.
