But… there also has to be room for us to change our understanding of reality. An overly dogmatic approach to science keeps us in the dark. The germ theory of disease was dismissed as pseudoscience for a long time, in favor of the widely accepted miasma theory.
Obviously, science requires a rigorous approach to examining reality. If an idea cannot be tested, it is not scientific and therefore exists only as speculation. But we can’t just assume that our current models of reality are fundamentally correct and unassailable - we know that they’re not, we know that the standard model is limited and fundamentally incomplete.
Check out this lecture: Consciousness and the Physics of the Brain. This idea is absolutely not science yet because we don’t really have the tools to test it. But consciousness as we experience it must be the product of physical processes at some level, and therefore it should be possible to study it scientifically.
