The Earth is populated with billions of conscious people (and, of course, other conscious living things too), and yet seemingly no philosopher, or anyone else, can find a use for their own personal consciousness.
They, including philosophers like David Chalmers, seem to get lost and tangled in the weeds of how consciousness feels, or doesn’t feel in the case of thoughts, and can’t find a use for their own personal consciousness.
The assumption seems to be that physics has already fully explained everything about the world, including the underlying goings-on in living things, and so a separate consciousness is somehow superfluous to requirements.
But in fact, physics has NOT fully explained everything about the world, because, as some physicists have occasionally pointed out, the equations of physics do NOT represent a viable moving real-world system.
There is a big difference between a set of equations (that symbolically represent fundamental-level real-world mathematical relationships between categories like mass or position), and the symbols needed to represent a viable moving real-world system.
In addition to the equations of physics, in order to represent a viable moving real-world system, you need to use symbols representing the following fundamental-level aspects:
- An on-the-spot knowledge/ consciousness aspect, i.e. the system needs to know its own on-the-spot categories, relationships and numbers.
- An on-the-spot “creativity/ free will” aspect that moves the system, i.e. jumps some of the numbers that apply to the categories, whereby other numbers that apply to other categories will also move, due to the mathematical relationships.
I.e. knowledge. consciousness and creativity/ free will are necessary aspects of a viable moving real-world system: the equations of physics are not sufficient to represent ALL the necessary aspects of a viable moving real-world system.
The other 2 things to note are: 1) that consciousness must inevitably be a SEPARATE aspect of a viable moving real-world system, because a different set of symbols is required to represent this aspect of a viable moving real-world system; and 2) being a SEPARATE but necessary aspect of the real-world system, consciousness is therefore relevant to the physics of the world.
