Most philosophers do not want intellectual matters to reduce to a question of morality (obedience or rebellion to God's Word). They want to hold the intellect or reason to be above matters of moral volition. They hold that truth is obtainable and testable no matter what ethical condition the thinker is in.
Hence, they maintain that all disputes must be rationally resolvable, and a rational case for a philosophic position relies on a valid chain of discursive argumentation that takes us back to incontestable first principles or facts.
