While I don’t totally disagree with you, nor advocate the position you are arguing against… I wonder what is the scientific definition of sanity? Is there a consensus on it? If it is a concept that exists outside the context of our society as you claim, then is it something objectively inherent in all humans regardless of their culture or circumstances? Or can its meaning change over time; can the standard of entrance be lowered or raised depending on current trends or the whim of the majority?
