Extract

There is a problem about belief and knowledge in Plato's epistemology that has exercised serious students of Plato only to settle into a recent orthodoxy. Guthrie characterizes the problem and its current resolution this way: ‘In the Meno doxa appeared to be a dim apprehension of the same objects (Forms and the necessary truths of mathematics) of which knowledge is a clear and complete understanding … in the Republic each is directed to different objects, knowledge to the Forms and doxa to the sensible world alone … at least the opinion seems now to prevail that on the relationship between doxa and knowledge Meno and Republic are irreconcilable, and exhibit a complete change of mind on Plato's part.'

Guthrie refers to the controversy regarding the continuity and discontinuity between δόζα and knowledge in the Meno and Republic at IV, 489, n. 3.

3 See, for example, the use of οἰέται at 82el0; ἔμοιγϵ δοχϵῖ οὕτω at 83dl; δοζάζων at 97bl. Also Plato frequently uses cognate forms of the verb ‘to agree’ to express belief, e.g., ὡμοƛογήχαμϵν at 97al.

4 This is clear from an examination of the texts cited in note 3. E.g., the grammatical object of δοζάζων at 97bl is the clause ἥτιζ ἐστὶν ἡ ὁδὀζ.

5 It is a matter of some controversy whether Plato, prior to the Sophist, distinguished precisely and for logical and epistemological purposes the roles of subject and predicate. For defense of such a distinction earlier than the Sophist, see Fine, G., ‘Plato on Naming,Philosophical Quarterly, 27 (1977) 289301CrossRefGoogle Scholar. For our current purposes, however, I think that this issue can be avoided. If the agent of an act of believing takes his belief to be about something outside of that belief, then this something can be named or pointed to either by the belief-statement as a whole or by its subject term.

9 In contrast to Rep. V, where δόζα is explicitly called a δύναμιζ, a power or capacity. On dispositional and occurrent senses of belief, see DeSousa, Ronald B., ‘How to Give a Piece of Your Mind: or, The Logic of Belief and Assent,' Review of Metaphysics, 25 (1971-72) 5279Google Scholar.

8 For an interesting discussion of the role of questions in understanding belief in the Meno and the paradox of inquiry, see Lawrence Powers, H., ‘Knowledge by Deduction; Philosophical Review 87 (1978) 343-52.CrossRefGoogle Scholar

10 For discussion, see Hintikka, J., ‘Knowledge and Its Objects in Plato,’ Ajatus, (1971) 168200Google Scholar, especially 177-80.

11 It is Just this feature or set of features that Plato returns to when, at Tim. 51e, he sets out reasons for distinguishing νοῦζ from δόζα ἀƛηθήζ.

12 Most likely, then, the diversified questioning at different times, mentioned by Plato at 85c10-d1, is intended by him as a pragmatic device for moving someone from true belief to knowledge. On such a reading, this questioning is not identical with the ‘bond’ or αἰτίαζ ƛογισμῷ that conceptually distinguishes one from the other.

13 I have in mind, of course, the well-known treatments of falsity in the Theaetetus and the Sophist.

14 Cherniss, Guthrie, and Gulley are strong advocates of Forms as the objects of recollection in the Meno. See Cherniss, Harold, ‘Review of Klara Buchmann, Die Stellung des Meno in der platonischen Philosophie,’ American Journal of Philology, 58 (1937) 498Google Scholar; ‘Plato as Mathematician,’ Review of Metaphysics, 4 (1950-51) 421; Guthrie, IV, 249 n. 3, 253-4 n. 3; Gulley, , ‘Plato's Theory of Recollection,’ Classical Quarterly, 3-4 (1954) 195-7Google Scholar. Neither the textual nor the philosophical arguments for the Forms, however, are secure. Meno 86a-b, when carefully examined, turns out to be a dialectical argument the premises of which do not unambiguously point to Forms as the objects of only disembodied knowing but indicate as well that the objects of knowledge are also those of true belief and that they are in the soul. Furthermore, as White, (Plato on Knowledge and Reality [hereafter PKR) [Indianapolis 1976], 59Google Scholar n.13, 54 n.5, 59 n.35) and Irwin, (Plato's Moral Theory [hereafter PMT) [Oxford 1977], 316Google Scholar n.15, 315 n.12) have shown, belief and knowledge have a very extensive scope in the Meno. Nor is the paradox of inquiry a problem about a priori learning or about a regress that might develop if all learning were thought to be empirical; rather it is a paradox about self-initiated or self-appropriated inquiry that is restricted not by the character of the subject matter but only by the resources available to the student when the inquiry begins. With Ross, I find it an impressive fact that nowhere during the discussion of the paradox of inquiry, the doctrine of recollection, and thereafter are the transcendent Forms mentioned. The reason for their absence is neither neglect nor design; it is simply that Plato had not discovered them yet - or at least no dialogue prior to the Phaedo decisively testifies to that discovery.

15 White has a helpful note on this distinction in the dialogues, PKR, 54-5 n.8.

16 On the broad view of the objects of belief and knowledge in the Meno and on Plato's neutrality regarding the specification of such objects, see White, PKR, 48-9, 59 n.35; Irwin, PMT, 315 n.12, 316 n.15. The narrower, a priori view is advocated by Vlastos, Gregory, ‘Anamnesis in the Meno,’ Dialogue, 4 (1965) 154-7Google Scholar; Gulley, , ‘Plato's Theory of Recollection,’ 194-5, and Plato's Theory of Knowledge (London 1962), 1415Google Scholar; Guthrie, IV, 261.

20 In the terms we introduced earlier, the two cannot have the same external object. Since Plato has not yet clarified the precise role of the external object as the object of the agent's reference, the separation of objects seems to open up a chasm between belief and knowledge.

23 Cf. Rep. VII, 519b and X, 611e-612a. The philosopher avoids the dictates of pleasure and pain, i.e., he avoids treating pleasure as the good, because to do so would lead to treating those objects that bring pleasure as the most real. In the Phaedo, then, hedonism is rejected at least in part because it leads away from knowledge and wisdom.

24 On ἀƛηθήζ, see Gallop, Plato Phaedo, 144.

25 Later, Forms are introduced as αἰτίαι (l00bff.). But never in the Phaedo does Plato seem to appreciate the difficulties surrounding the notions of participation, presence-in, and copying, notions that are intended to characterize the relation between Forms and physical objects.

26 Education also insures the continuance of Justice and the other virtues from one generation to the next. That is, it insures that Justice is a permanent possibility.

27 While it is a primary credential, it is of course not the only one; other features of the philosopher's character and desires are relevant as well. Similarly, while it is a necessary condition for the highest kind of well-being, knowledge is not necessary for lesser forms of well-being, or derivative forms (cf. IX, 590c2-d6).

28 Similarly, the first task of the Socratic elenchos is to awaken in the interlocutor a realization of his own ignorance. Cf. Meno 84a3-d2.

29 Strictly speaking, belief and knowledge in Rep. V-VII have as their scope what F is. See Mills, K. W., ‘Plato's “Non-hypothetical Starting Point”,’ Durham University Journal, (date not known) 152-9Google Scholar.

31 The non-philosophers are the ‘lovers of sights and sounds.’ See Rep. V, 475dl-476d6. Cf. Phaedo 65e-67b, 78b-84b; Hippias Major 298aff.

32 It may also seem natural to seek such an account in the image of the Cave. But the Cave, as Plato explicitly says (VII, 514al-2), is a likeness or simile for παιδϵία. It is better, I think, to turn first to the curriculum and the very substance of that παιδϵία and only later to return to the Cave for confirmation.

33 Cf. V, 476d5; VI, 508e4; VI, 510d6; 5llal; VII, 533d-e.

34 Some will object that in the Line διάνια is clearly situated in the upper section of the whole and so must be a kind of νόησιζ or ἐπιστήμη and not of δόζα. Technically speaking, this is correct. Perhaps it would be more precise to say that διάνοια is a kind of thinking but one that is akin to belief in some ways and to knowledge in others. I choose to call it a kind of belief, however, because it is then clear that διάνοια involves some kind of assent or commitment, while mere thinking does not.

35 For samples of such discussion, see the articles cited in notes 19 and 30.

36 Exactly how this works is not our present concern. According to Plato's description, it involves the ‘joint presence of contraries’ in a single perception. What this means and how it leads to aporia (VII, 524e5) are matters of dispute.

37 In this paper I do not develop any direct argument concerning whether for Plato knowledge of the Forms is a direct mental grasping or propositional or both. For discussion, see the papers cited in note 30. Indirectly, some of things I say do give support to the view that in some sense knowledge of the Forms is both propositional and non-propositional.

38 Plato discusses, but does not really distinguish carefully, both an act of mathematical thinking and the process of mathematical thinking. My concern here is only with the former. For that reason, we can avoid any detailed consideration of the hypothetical character of mathematics and its relation to the upward and downward paths of dialectic.

39 This may very well be a direct allusion to the Meno and the dialogue with the slave-boy, the topic of which is a theorem about squares and diagonals.

42 One might take this to be contrary to Plato's explicit wishes, expressed at VII, 517a-b. For a critique of the parallelism between the Line and the Cave, together with an alternative reading of VII, 517a-b, see Robinson, PED, Ch. XI, especially 185-90.

Even Wedberg, a serious advocate of a Platonic theory of intermediates in the tradition of Adam and Hardie, is extremely cautious about the presence of that theory in the Republic (Wedberg, A., Plato's Philosophy of Mathematics [hereafter PPM] [Stockholm 1955]) 109Google Scholar; cf.

50 The expression ἤ ὅσων οἱ παρϵƛηƛυθότϵζ at VII, 534a8 refers back to VI, 510c -d.

51 Brentlinger's claim, that 534a by itself indicates an ontological difference between the objects of διάνοια and those of νόησιζ (156), is simply a non sequitur.

62 Wedberg (PPM, 123-4) takes the plurality of units, referred to at 526a, to be the units that compose the mathematical numbers; Hardie (Study, 53) holds that these units are the mathematical numbers themselves.

64 For helpful comments on earlier drafts and discussion of issues in the paper, let me thank John Ackrill, Richard Kraut, Romane Clark, and the editors of the Canadian Journal of Philosophy. In thinking about the role of agent-reference in Plato's epistemology, I have been greatly helped by the work of Hector-Neri Castañeda. Almost singlehandedly he has produced an exciting literature on the problems of reference within propositional attitudes with special attention to the roles of, what Castañeda calls, indicators and quasi-indicators. Plato's thinking about matters such as agent-reference is very rudimentary, but it does play a role, as I have tried to show, in his central epistemological project, the inquiry into what is real. i.e., into what F is, and the acquisition of knowledge of the Forms.
