The way I see it is that philosophers are interested in questions which have no conclusive answer. Ethics - study of moral issues. Philosophy of Science - philosophical aspects of science. I am a university graduate of Philosophy and Psychology and I am particularly interested in Philosophical Psychology. However, studying philosophy doesn't necessarily make you good at it.
Philosophy can be a very difficult subject, but everyone can offer insight.
In fact even pre-school children can make very astute observations. So, I would not claim to be an expert, merely a person who would like to take part in interesting discussions with others. I am not pretending to be able to offer full and comprehensive coverage of all issues. Please do not e-mail me in anger telling me that I have misinterpreted points. You can, of course, put your opinions on the forum.
