There are those, such as scientists, who see only the outside of reality, its appearance, its surface, its phenomenal aspect. They are blind to the inside, the substance, the foundation, the noumenal aspect. They dismiss it as non-existent, or illusion, or epiphenomenon. Scientists are those that believe that phenomena have no underlying noumena. What you see is what you get. Seeing is believing. Everything is appearance. Nothing is concealed. There are no hidden variables, and no unobservables. The scientific method says, "Observe". That works only if everything is observable. If there are foundational unobservables, science is catastrophically wrong and has cut itself off from the truth. The only "truth" it can furnish is that of surfaces and appearances with no substance. Those who truly want to understand reality must become masters of both perspectives – inside and outside, noumenon and phenomenon – and see how they relate, communicate and interact.
