Contrary to postmodern relativists, the growth of human knowledge is a fact. But that fact does not make human beings any more likely to be virtuous, or rational. However fast and far science may advance the dilemmas that beset us, ethics will remain as problematic as before. Indeed, since the increase in knowledge enlarges the power to do evil, these dilemmas may be more formidable.
