Not exactly, but it is a cultural and contextual truth that is fundamentally different than a physical reality. Don't get me wrong, I am not saying that morals are any less meaningful than provable facts. There are many times where morality and even irrationality is of more consequence and more to the point than what we can gather scientifically. Indeed, the simple motive to uncover and catalog facts is based in a system of culture and belief. Not only do I believe that it is meaningful to have beliefs that include moral values, I feel it is inescapable, and thus, the search for a rational philosophy is Quixotic.Do you deny that a sentence like "Actions that do not cause unnecessary suffering are better than actions that cause unnecessary suffering" can be true or false?
