This proof, based on the assumptions of modern science and medicine, reveals how we are unable to move our bodies even for the simplest of tasks, such as blinking an eye, or lifting a finger. In view of our easy ability to blink, or move a finger, we may confidently conclude that standard scientific theories -- reliant on the assumption of 'perfectly contiguous and continuous' movement -- are inappropriate and incorrect at the micro-scaled dimensions of space-time, but approximately correct in the macro-scaled events of everyday life1.
This proof focuses on the issue of first-cause. What enables or makes us think, e.g. about thinking? The brain-as-computer metaphor has serious shortcomings, chief of which is the inability to explain the impetus to think: before we think, what must we do? Less well known, but even more telling is the inability of brain-as-computer metaphors to accommodate and explain how the computer model operates in the quantum realm involving fields of potentials and possibilities; realms within which all brain 'stuff' is bathed.
As Freeman Dyson explained:
Quantum mechanics makes matter even in the smallest pieces into an active agent, and I think that is something very fundamental. Every particle in the universe is an active agent making choices between random processes.2
What enables particles of our brain-stuff to make choices between random processes that can't be physically predicted or modelled?
