I'm reading "The philosophy of science" by Stephen Toulmin, a book I happened to find amongst an old flatmate's massive collection of old books when we had power cuts during an earthquake and I needed something to do. It'd old, 1953, and it's got that 'damp paper' smell common to old books, but it's a damn good read and most of the content is still valid even though the examples he uses to illustrate his ideas is a little dated at times.
