Sherman: “I assume you will agree that facts, principles, theories, suppositions, presuppositions are all matters of opinion? That there is no way to prove that any of them are true or untrue. By which I mean proof with the certainty of a mathematical axiom.”
Spirited: If as you say, all theories are matters of opinion with “no way to ‘prove’ that any of them are true or untrue” with the “certainty of a mathematical axiom” then Darwinism, materialism, empiricism, and naturalism are nothing more than someone’s opinion, an opinion that originates in the unseen realm of the mind rather than in the senses.
Like your dreams, aspirations, and misplaced belief that physicalism is our only source of knowledge, opinions originate in the spirital dimension (mind) and cannot be sensed.
Empiricism, Darwinism, physicalism and naturalism are absurdities. All are devoid of life, consciousness and soul, hence all are self-refuting theories. They self-anihilate because all are forms of nihilism.
They deny the very thing that brought them into existence.
