The Cambridge History of Later Medieval Philosophy finds its natural place after The Cambridge History of Later Greek and Early Medieval Philosophy in the sequence that begins with Guthrie's History of Greek Philosophy. The sequence is not altogether smooth, however. At the beginning of The Cambridge History of Later Greek and Early Medieval Philosophy its editor, A. H. Armstrong, observes that although the volume ‘was originally planned in connexion with W. K. C. Guthrie's History of Greek Philosophy, … [it] has developed on rather different lines, and is not exactly a continuation of that work’ (p. xii). Similarly, although The Cambridge History of Later Medieval Philosophy was conceived of as the sequel to The Cambridge History of Later Greek and Early Medieval Philosophy, the relationship between the two is not so simple as their titles suggest; in fact, the fit between this volume and the Armstrong volume is less exact than that between the Armstrong volume and Professor Guthrie's plan. Many reviewers noted that the Armstrong volume seems misleadingly titled since it is really a study of only the Platonist tradition in later Greek and early medieval philosophy; but in concentrating in that way it does indeed complement Professor Guthrie's plan, which includes the Stoics and Epicureans as well as Aristotle while leaving out the Neoplatonists. On the other hand, The Cambridge History of Later Medieval Philosophy cannot be put forward as the full realisation of Professor Armstrong's expressed hope ‘that the philosophy of the thirteenth century and the later Middle Ages in the West, with later Jewish, Moslem, and Byzantine developments, will some day be dealt with in another Cambridge volume’ (ibid.).
