Who am I? It is difficult for me to recognise myself in a photo taken when I was 5 and to identify with the thoughts I had when I was 16. But I can do that because I have a ‘sense of self’ which includes beliefs about myself that address two basic questions: which person I am and what type of person I am. The first question can be answered by reference to my life history (e.g., when I was born, who my parents are, what my job is) and the second question concerns my personality and dispositions (e.g., whether I am loyal, whether I am good at playing volleyball, whether I like Russian literature).
