I would like to recommend two books I just read: Christopher Janaway on Schopenhauer and Patrick Gardiner on Kierkegaard, both in the Oxford series of Very Short introductions. Both are very well written, clear and informative, as well as off the beaten track. I was particularly interested to read Gardiner’s book as I knew him at Oxford when we both examined the John Locke Prize together and found him quite remarkably likable. He was by no means a central figure in Oxford and kept his distance from philosophical fashion, but he should have been regarded as something of a treasure, given his areas of expertise. I should have made an effort to get to know him better.
