'The earlier volumes of Professor Guthrie's great history of Greek Philosophy won their due acclaim, and the series is now crowned by this massive volume, the records of what the author, with characteristic dry wit, calls an 'Encounter' ... it carries an immense weight of learning in ancient philosophy and knowledge of modern thought, as well as total command of Aristotelian scholarship all neatly distributed between text and footnotes, so that it can be read with or without the latter, according to taste, grasp and knowledge of Greek ... The end crowns the life not only of a great scholar but of a man whose modesty, humour and irony glint through many a page.' Bulletin of the Joint Association of Classical Teachers
'... the record of the meeting of two minds. It is illuminated by a vivid intellectual excitement, and by an affection for Aristotle that may surprise those who find him too forbiddingly rational to be loved ... For undergraduates, nervously approaching this philosopher for the first time, it will be the most encouraging, illuminating and informative account that they are likely to meet.' Andrew Barker, University of Warwick
