The "A Very Short Introduction" series doesn't always come up with good books, but this one is a gem. It really is. It introduces the basics first: deduction, induction, etc. and goes on to talk about the problem of induction, Hume's criticism of it, whether thinking about probability and causation can help. The discussion moves then onto realists vs. anti-realists. The highly influential philosopher Thomas Kuhn is also well covered. Finally, the book covers some problems in biology and physics and generally that result from science. The book is brief and you can read it in a long evening or maybe two short ones, if you're not already familiar with the subject. Most importantly, the author manages to realise that newcomers to the subject deserve a gentle ride, and he does this by writing very accessibly and using plenty of easy-to-understand examples. I would recommend this to anybody trying to find a way into the philosophy of science. Of course, being a "very short introduction" this book doesn't tend to go into very much detail or cover everything that philosophy of science entails. But a very short introduction can't have everything. For beginners I think it is ideal, and that is what it aims to be. Highly recommended.
