Individual consciousness is the aspect of the world that says what is true. This truth is felt/ experienced/ known. There is no external-to-this-world, abstract, Platonic, arbiter of truth.
In the case of the most basic matter, the most basic consciousness is of what categories, relationships, and numbers “are now true”. This is not a case of consciousness being a “static block universe position pointer”, or Julian Barbour’s somewhat similar view, because there is no “static block universe”. Instead, in a moving, changing, evolving universe, what categories, relationships, and numbers exist does not logically imply knowledge/ consciousness/ awareness of what exists. What exists does not imply knowledge of what exists; therefore a viable universe requires a knowledge aspect.
This knowledge/ consciousness/ awareness/ “is now true” aspect of the world can only be represented with the “IS TRUE” logical symbol; equations and numbers alone can’t represent what “is now true”.
But in the case of higher-level matter, there is a vast myriad of information that is simultaneously true, including executive analyses and summaries of this information. And to symbolically represent this simultaneously true conscious experience requires a vast number of “AND” symbols.
So, for example, our visual picture of the world, with its labels for objects in the picture, is a type of executive analysis, summary and collation of what individual particle interactions very recently occurred in the eyes. Simultaneously, we experience an aural “picture” of the world, and so on.
But the point I am making is that individual consciousness is the aspect of the world that says what is true.
