John of Alexandria is an obscure figure. Little is known of his life: his floruit is placed in the first half of the seventh century A.D. He was a practising doctor; the exact significance of the epithet ‘sophista’ which is found on the superscription to his commentary on the sixth book of Hippocrates' Epidemics is uncertain: but it may indicate an interest beyond the purely medical. Apart from the commentaries on the Epidemics and De Sectis, the only other work ascribed to him with any certainty is a commentary on the Hippocratic text On the Nature of the Child, although four other works traditionally attributed to Philoponus and of a purely medical nature have been ascribed to him.
1 The texts of Galen are cited in general by way of C. G. Kühn's monumental, if inadequate, Leipzig edition of 1821–33 (20 vols. in 22); where later and better editions exist, either in the Teubner or the Corpus Medicorum Graecorum (CMG) I have sometimes (though not invariably) added those references as well. This is unwieldy, and unsatisfactory in many ways, but until a proper edition of the Galenic æuvre; becomes available (if it ever does), there is no better method. ‘CIAG’ refers to the Commentaria in Aristotelem Graeca; the other references are self-explanatory.

10 Extensive at least by comparison with some comparable texts that survive only in medieval Latin versions.
11 The work contains some scholarly irritations however: in particular, Pritchet's references to the rest of the Galenic corpus are unsatisfactory, in two distinct ways, (a) The references are sometimes confusing: he refers to Galen's short treatise Ad Glauconem de Medendi Methodo (xi 1–146Kühn, )Google Scholar as ‘De medendi methodo’ (e.g. at Pritchet, 1982, pp. 24, 33)Google Scholar: but he also uses the same designation (at p. 37) to refer to Galen's masterpiece of therapeutics De Methodo Medendi (Meth. Med.), x 1–1021Kühn, Google Scholar. (b) More importantly, he does not distinguish between the authentic texts of Galen and those that are either (i) clearly spurious, or (ii) of doubtful provenance. As examples of (i), he refers throughout to Introductio, sive Medicus (Int.) xiv 674–797Kühn, Google Scholar, and the Definitions Medicae (Def. Med.) xix 346–462Kühn, Google Scholar as if they were genuine, when they are universally acknowledged not to be. In class (ii) fallDe Optima Secta (i 106–223Kühn, Google Scholar, which is almost certainly at least in part a forgery) andDe Theriaca ad Pisonem (xiv 210–310Kühn, Google Scholar, which is doubtful). All these texts are included, apparently as genuine, in the list of citations appended to the work (pp. 98–9), and in the preface Pritchet refers to the Introductio as if it contained Galen's, ipsissima verba (Praef. pp. viii–ix)Google Scholar.
12 Pritchet refers these divisions principally to [Gal.] Int. xiv 689–90 Kühn, Google Scholar, although pseudoGalen's division there is substantially different from that to be found in John (even allowing for the obscurities generated by textual difficulty). The most important divergence is that pseudo-Galen does not distinguish between theoretical and practical, although that distinction is to be found in the genuinely Galenic On the Constitution of the Art of Medicine (Const. Art. Med.) I 227–33 Küuhn, Google Scholar; the division of τ⋯χναι into theoretical and practical, with the latter divided further into the acquisitive and the conservative which we find both there and in John, 1 va 27–39 (see n. 13 for the system of references to John), albeit rather badly handled by the latter, goes back to Plato: Soph. 219a–d. See further Galen's, De Partibus Artis Medicativae, translated from the Arabic by Lyons, M. (CMG Supp. Or. II, 1969)Google Scholar; and cf. Galen's Subfiguratio Empirica (Subf. Emp.), ch. 5, for the account of the Empiricist doctors; the proper division of the art of medicine was a matter of deep and abiding importance to the Greek doctors.Subf. Emp. is printed as fragment 10b of Deichgraber's, K.Die Griechische Empirikerschule (Berlin, 1930)Google Scholar, and translated by Frede, Michael, in Galen: Three Treatises on the Nature of Science (Indiana, 1985)Google Scholar. Note also Aristotle's, division of τέχναι into theoretical, practical, and productive: Met. 6 1, 1025b25Google Scholar.
13 Pritchet keys his text to some earlier version (either a manuscript of a very early printed edition: thus ‘1 va 12’ would refer to line twelve of column ‘a ‘ of the verso of the first folio), hence the somewhat peculiar references in this article; but he nowhere seems to say which earlier version it is. Accordingly, I follow his system, but cite page numbers of his edition as well.
14 As Pritchet prints it, John's text is unnecessarily clumsy: ‘habet igitur medicina speculativum (ӨεωρητικΌν) et activum (πρακτικΌν), sed speculativum dividitur in phisiologion (ӨυσιολοκΌν) et ethiologion (αῚτιολογικΌν)… tertium sumoticon (σημειωτικΌν) quidem est significativum,’ etc. (1 vb 13–16, p. 11 Pritchet). It would be much clearer if'et sumoticon’ were read after ‘ethiologion’ in 1 vb 14 (this would further involve excision of the ‘et’ before ‘ethiologion’); these words might very easily have fallen out of the text. Even easier palaeographically would be the insertion of ‘sumoticon’ between ‘phisiologion’ and ‘et'; but the order of treatment in the succeeding lines makes this unlikely.

VII 524–8 Kühn, Google Scholar. I discuss these issues in my art. cit. (n. 15), esp. pp. 80–6.
19 Lampe gives ‘hold out’ and ‘offer’ as possible meanings for the term, although given the paucity of the attestations it is not clear on what basis he does so.
20 Although given the second occurrence of ‘proepticon’ at 1 vb 23 in all but one of the MSS. (which omits the crucial part of the sentence altogether), this would involve two stages of textual corruption - first 1 vb 20 is corrupted involuntarily by assimilation of prefixes; then at a later stage 1 vb 23 is ‘corrected’ to coincide with the corrupt reading. I am grateful to the Editors for pointing this out.

Proc. vi 57 =CMG Supp. n 15.3–8: ‘unu m utique est hoc genus, quod sive id quod propter quo d [i.e. οὗ χ⋯ριν] fit volueris nominare, sive utilitatem [i.e. χρεíα] generationis eius quo d fit, sive finem [i.e. τ⋯λοσ], sive intentionem [i.e. σκοπΌσ] nichil differt’ (see my op. cit. n. 16 above, ad loc.) an d cf. Us. Part, III 464–71 Kühn, Google Scholar, where σκοπΌσ and τέλοσ are used interchangeably, as they are (apparently) at Symp. Diff. VII 47Kühn, Google Scholar(cf. the remarks of Stobaeus, n. 23 below).
23 Fo r an excellent discussion of this apparently paradoxical belief, and a convincing defence of its coherence, see Striker's, Gisela ‘Antipater, or the art of living’ in Striker, G. and Schofield, M. (edd.) The Norms of Nature (Cambridge, 1986), 185–204Google Scholar. Stobaeus ascribes three definitions of τέλοσ to the Stoics, according to the second of which it is equivalent to σκοπΌσ (the third is the definition appropriate to the sort of distinction just mentioned): Eel. 2 76, = SVF3 3; cf. ibid. 2 77, =ibid. 3 16). Inwood, B., in Ethics and Human Action in Early Stoicism (Oxford, 1985), p. 58Google Scholar, writes of ‘the distinction between σκοπΌσ, a material object, and τέλοσ, a λ⋯κτον closely related to it’ ; but that characterisation does not seem to do justice to the distinction as we find it in Galen.

25 Pritchet prints ‘considerate’, which makes no sense; I do not know whether this is a misprint, or represents something in the MSS.
26 What can this mean? Does it translate αἷρεσισ though not in its sense of ‘medical sect’ but rather in its general sense of ‘grasping’? This seems unlikely. Michael Frede suggested, in a private letter, that we should read ‘intentio’ for ‘secta’, which at least gives a clear sense, and would restore a balance to the sentence - but the emendation is palaeographically unsatisfactory. It may be, as David Sedley suggests, that the text is correct as it stands, and that ‘secta’ does have its technical sense, the idea being that the overall goal of medicine is the completion of medical science.
27 Michael Frede suggests reading ‘perficeretur’ for ‘finit’ (which is certainly harsh), which gives an excellent sense, although such a corruption is difficult to account for. David Sedley suggests ‘ut direxerit finis, est intentio’, which is easy palaeographically, and gives the sense ‘when the goal directs it, it is an aim’ (presumably distinguishing genuine aims from mere happenstance successes); it also allows the possibility that John's conception of the relation between ακοπΌσ and τ⋯λοσ is broadly speaking that of the Stoics (although it does not entail it: see n. 23 above). None of this is, however, central to our current concerns.

29 For this later addition to the Peripatetic causal categories, see my op. cit., n. 16 above. The Neoplatonists of the fourth century and later adopt a six-fold taxonomy of Efficient, Material, Formal, Final, Paradigmatic, and Instrumental Causes (see Philoponus, , In Phys. II, CIAG xvi 5.7ff.Google Scholar; Simplicius. In Phys. II, CIAG ix 10.35–11.4)Google Scholar; the first five causes are to be found in Seneca, Ep. 658.

Aristotle himself mentions tools, ⋯ργανα, in his discussion of causes: Phys. 2 3, 195al–3, Met. 5 2, 1013bl–4; but they do not figure as a separate causal category either in Aristotle or in later Peripatetics such as Galen's contemporary Alexander of Aphrodisias: see Alexander, , de Fato 3, vol. 2, p. 116.15 26Google ScholarBruns, , = Sharpies, R.

40 One might cite Phys. 2 1, 193bl3ff. as a case in which εῚσ ὃ occurs in a more or less parallel context: but the similarity is only superficial (Aristotle is not concerned with the rigorous classification of causes, only with the preliminaries of the investigation into the nature of nature); and in any case, εῚσ ὃ clearly picks out the Final cause (or the fully-actualized form) if it picks out anything.
