Review Questions

• How does J.L. Mackie's perspective on error theory challenge traditional views on moral realism?
  • Mackie's perspective on error theory challenges traditional views on moral realism by arguing that there are no objective moral values or truths that can be discovered. He suggests that all attempts to make moral claims result in falsehood because they presume the existence of these non-existent values. This fundamentally opposes the realist notion that moral facts exist independently of human beliefs, thus reshaping discussions around the nature of morality.
• What implications does Mackie's critique of objective moral values have on the debate surrounding universalism and ethical standards?
  • Mackie's critique implies that if there are no objective moral values, then universalism—where certain morals apply to all people regardless of culture or context—becomes problematic. Without a foundation in objective truths, ethical standards must be seen as relative to cultural or individual beliefs, thereby challenging the validity of claims about universal morality. This perspective prompts a re-evaluation of how ethics is understood and applied across different societies.
• Evaluate the significance of J.L. Mackie's contributions to contemporary discussions about moral skepticism and subjectivism.
  • J.L. Mackie's contributions are significant as they lay foundational arguments for both moral skepticism and subjectivism in contemporary ethical discussions. By asserting that moral claims cannot correspond to any objective reality, he encourages skepticism about our ability to know what is truly right or wrong. Additionally, his emphasis on the subjective nature of morality challenges us to consider how much our ethical beliefs are shaped by societal norms and individual experiences, fostering ongoing debates about the validity and universality of ethical principles.
