I suppose I'd characterise this as medical philosophy. Admittedly, I don't have a great deal of patience for philosophy at the best of times, but this is very clearly written for a field which seems to delight in leaving as many people behind as possible. In short: normal people can understand it.

New Frontiers isn't so much a cohesive book as a collection of papers originally published in the Australian Family Physician. As such, there is quite a bit of repetition, but the gist of the collection is medicine needs to take a holistic approach. The papers that went into specifics were most effective, but these were the minority. Many had few references and honestly, I'm pretty sceptical about homeopathy and so on. A little less rambling about Plato and a lot more actual data might have been more convincing to me. Then again, I'm not the primary market for this book (GPs are, essentially) so what do I know.
