The AS course in philosophy and ethics begins with a study of a range of arguments some of which centre on one question – is it possible to prove that God exists? Both believers and non-believers are often surprised by the answer. This is followed by an investigation into the claim that miracles occur, sometimes in circumstances where people have survived in the face of impossible odds or where there are claims of miraculous medical cures. The existence of evil is also an area studied on the AS course, evaluating evidence which suggests both natural and supernatural explanations. Ethical questions relating to war, and sexuality are also part of the study of philosophy and ethics at AS. In ethics more specifically the focus is on how we can make a moral decision, and researching different methods and analysing their usefulness in everyday life. The A2 course offers the opportunity to study at a more advanced level arguments which support or challenge beliefs in life after death, including an evaluation of recent scientific evidence. Claims of religious experience and the nature of these claims are also an important area for investigation. Arguments against religion which form the basis of atheism also form an important part of the A2 course. Ethical issues relating to justice, law and punishment complete the study of philosophy and ethics at A2.
