Got what backwards? Are you speaking to me?
Scientific enquiry is never going to take up much room on a philosophy forum where we have to take the scientific data for granted. Philosophical dogmatism should take up no room at all.The ratio of scientific enquiry to philosophical dogmatism is not very healthy on this forum.
The non-dual philsophy of the Upanishads was endorsed by Schrodinger, who promoted in his writing for forty years. As it is grounded in experience it is considered a science and it meets Popper's conditions. if we have not had the experience to verify it then for us it is a theory, and if we believe the theory than for us it is a belief system. But it is not a belief system because all its claimed may be experimentally tested.
We may not believe this but if do not believe then we have a lack-of-belief system, for we cannot prove our lack of belief is justified.
If we take a scientific or philosophical approach we will not believe either way but will investigate and establish the facts.
