With a Good Theory of Knowledge, You Can Decide What Else Is True

What we test are new theories that seem to show promise of explaining things better than the prevailing ones do.

Quantum theory is, as I have said, one such theory. But the other three main strands of explanation through which we seek to understand the fabric of reality are all ‘high level’ from the point of view of quantum physics. They are the theory of evolution (primarily the evolution of living organisms), epistemology (the theory of knowledge) and the t

I must stress immediately that I am not referring merely to the ‘theory of everything’ which some particle physicists hope they will soon discover. Their ‘theory of everything’ would be a unified theory of all the basic forces known to physics,

We understand the fabric of reality only by understanding theories that explain it.

So what distinguishes understanding from mere knowing?

it is an investigation of what those theories say, and what sort of reality they describe.
