Over the years, the A level syllabi have covered various topics in ethics. The current (2017) AQA Philosophy syllabus covers utilitarianism, Kantian deontology, Aristotelian virtue ethics, metaethics and various issues in practical ethics. These topics are all discussed in handouts available from the Routledge companion website for A level philosophy.
My writings on topics in ethics that are supplementary to that collection will soon be collected here.
1. Normative and metaethical relativism and absolutism
3. A Relative Defence
4. Cognitivism and noncognitivism: Developments
6. Hume on reason and emotion
7. Moral knowledge
8. How can we tell right from wrong?
