“Moral questions may not have objective answers—whether revealed by God or by science—but they do have rational ones, answers rooted in a rationality that emerges out of social need. That rationality can only be discovered through exercising the human potential for rational dialogue, the potential for thinking about the world, and for discussing, debating and persuading others. Values can never be entirely wrenched apart from facts; but neither can they be collapsed into facts. It is the existence of humans as moral agents that allows us to act as the bridge between facts and values.”
