Isn’t it true that ultimately all truth is conventional? The system of logic, our inferences we accept, our physics, our views on reality; are all grounded in our presuppositions? To be intellectually honest there is no argument for objectivity. We have to retreat to commonsense realism and agreement among people and communities...so truth in reality is a matter of consensus! Even though none of us wishes to cop to that label. So logic, physics, science is all rhetoric or the art of convincing one of our views? Even if we hold that there is one God and His truth is absolute and objective - this is still a convention one must accept?
