Plato: Epistemology, Misc

This paper is a test case for the claim, made famous by Myles Burnyeat, that the ancient Greeks did not recognize subjective truth or knowledge. After a brief discussion of the issue in Sextus Empiricus, I then turn to Plato's discussion of Protagorean views in the Theaetetus. In at least two passages, it seems that Plato attributes to Protagoras the view that our subjective experiences constitute truth and knowledge, without reference to any outside world of objects. I argue that these (...) passages have been misunderstood and that on the correct reading, they do not say anything about subjective knowledge. I then try out what I take to be the correct reading of the passages. The paper concludes with a brief discussion of the importance of causes in Greek epistemology. (shrink)

In this paper, I explore two possible readings of Republic IV, 439c2-d8, and of Plato’s claim that the just soul is governed by its rational element. My aim is to argue against a “desiderative” interpretation of the passage, according to which the motivational strength of rational desires depends on a set of desires given in advance and produced independently of reason. As an alternative, I advance a “cognitivist” reading according to which the rational desires of the just soul have as (...) its ultimate source a knowledge about the nature of goodness and happiness, with its own motivational force. Finally, I argue for a reinterpretation of 439a4-b1, a passage that, at first sight, seems to contradict my analysis of 439c2-d8. (shrink)

I argue that the type of progress exhibited by philosophy is not that exhibited by science, but rather is akin to the kind of progress exhibited be someone becoming ‘older and wiser’. However, as actually-existing philosophy has gotten older, it has not always gotten wiser. As an illustration, I consider Rawls's conception of justification. I argue that Rawls's notion of what it is to have a philosophical justification exhibits no progress at all from Euthyphro's. In fact, drawing on a remark (...) of Wittgenstein's, I suggest that Rawls's conception is inferior to the situation as depicted in Plato's famous dialogue – because at least in the case of Plato's Euthyphro, there is no illusion of justification.

The central question of the Euthyphro is “Is the pious loved by the gods because it is pious, or pious because it is loved?” A baseball analogy explains this to students: “Does the umpire say ‘Out’ because the runner is out, or is the runner out because the umpire says ‘Out’?” The former makes the relevant knowledge public, making Socrates the appropriate secular moral authority, while the latter makes it religious, invoking Euthyphro’s expertise. Foucault’s aphorism that power is knowledge illuminates (...) how the aristocracy stands behind Euthyphro, while Socrates empowers the democracy. An abstract epistemological question has important political consequences. (shrink)

John Mackie famously dismissed the rational tenability of moral objectivism with two quick arguments. The second, the so-called “argument from queerness,” proceeds as follows. A commitment to moral objectivism brings with it a commitment to the existence of moral properties as “queer” as Platonic Forms that are apprehended only through occult faculties like so-called “moral intuition” (Mackie 1977, 38). Since we have no reason to believe that there is any faculty such as moral intuition that serves as a reliable Form (...) detector, we equally have no reason to accept moral objectivism (1977, 23–24, 38–41). Recently, Julia Annas has observed that Mackie has offered us “a coarse and imperceptive interpretation of Plato,” in addition to a mistaken account of the epistemic requirements of moral objectivism (2001, 238). But one might worry that the case Annas makes for the homely nature of Platonic moral knowledge—it’s just like plumbing, only non-optional (2001, 246)—rests, as she admits, on her focus on dialogues like the Laches, in which the analogy between the moral virtues and crafts like flute-playing, shoe-making, and navigating is emphasized (2001, 244). Annas explicitly leaves open the question whether Mackie’s interpretation might capture Plato’s conception of moral knowledge in dialogues like the Republic, in which the analogy between moral and mathematical knowledge is emphasized (2001, 243). Yet it is clear from Mackie’s brief remarks about Plato that he has the Republic primarily in mind (Mackie 1977, 23–24). (shrink)

The paper refers to the contribution of myth to Plato’s cognitive theory. Primarily, it is epigrammatically pointed out the existing difference between Mythos and Logos, on the one hand, and Plato’s attitude towards the myths as well as their use and incorporation into his cognitive model, on the other hand.

What does Socrates mean by suggesting that no one can understand the nature of the soul "without the nature of the whole" (Phaedrus 270c)? I raise epistemological and metaphysical questions for Mary Louise Gill's proposal that he means us to consider the whole environment, and I make a case for the old-fashioned interpretation that he means us to consider the whole cosmos.

Plato's comments on astronomy and the education of the guardians at Republic 528e ff have been hotly disputed, and have provoked much criticism from those who have interpreted them as a rejection or denigration of observational astronomy. Here I argue that the key to interpreting these comments lies in the relationship between the conception of enquiry that is implicit in the epistemological allegories, and the programme for the education of the guardians that Plato subsequently proposes. We have, I suggest, been (...) too eager to stress the similarities here, when recognition of the differences may supply us with the tools required for a better understanding of 528e ff, one that to a large extent disarms the anti-empirical critique. My discussion proceeds in three stages. Firstly, Plato takes great care to place his comments on astronomy in the context of the preceding epistemological allegories. Is there any evidence here, where Plato might be thought to discuss enquiry in general, that he rejected or denigrated observation? I argue that even if Plato advocated a 'Two Worlds' (TW) ontology, he still envisaged a dynamic process of enquiry, interrelating sensibles and intelligibles, the investigation of each being necessary but not sufficient to achieve the overall aim. Secondly, Plato appears to be deriving how we ought to go about educating the guardians from how we ought to conduct our enquiries. While the two are intimately related there are important differences, recognition of which turns the supposed rejection of observation into an affirmation of the need for an initial empirical approach. I contend that this makes good sense of the internal structure of 528e ff, and of its relations to other parts of the Republic. Thirdly, I discuss the Republic in relation to the evidence offered by later works on the question of astronomy and observation, and raise the question of whether Plato's views on the imperfection of the sensible world necessarily lead to the denigration of careful and prolonged empirical work.

Theaetetus, asked what knowledge is, replies that geometry and the other mathematical disciplines are knowledge, and so are crafts like cobbling. Socrates points out that it does not help him to be told how many kinds of knowledge there are when his problem is to know what knowledge itself is, what it means to call geometry or a craft knowledge in the first place—he insists on the generality of his question in the way he often does when his interlocutor, asked (...) for a definition, cites instead cases of the concept to be defined.

This book is not about the theory of Forms as such, but about Plato’s epistemological realism, his view, in opposition to Protagorean relativism, that there is a realm of fact that counts as the common object of our true beliefs, judgments, and knowledge. This book fills a longstanding need for a lucid, condensed, readable account of aspects of Plato’s thought that emerge in certain of Plato’s middle and later dialogues and pose issues of contemporary philosophical merit. It is White’s contention (...) that Plato’s discontent with the "method of hypothesis" tentatively tried in Meno, Phaedo, and Republic, and his theory of naming in the Cratylus, lead to the breakdown of his theory of knowledge and, eventually, of the possibility of meaningful inquiry, with the objects of inquiry framed in advance by a specification of the object. The key thesis in White’s contention appears to be a view that he attributes to the Cratylus, that "the genuine use of a name is thought to require the apprehension of its nominatum, in a way excluding any confusion of it with other things" ; for, if the only thing that can be named is a Form, and if believing, judging, and knowing are a kind of being confronted in one’s mental "visual" field with an object, and we cannot accept the beliefs of others for purposes of inquiry, then how is it possible to inquire about, or to define what one already apprehends and recognizes?

This paper argues that the concepts of writing and authorship in Plato are associated with monologism and absence rather than presence. The Phaedrus objects to writing precisely insofar as it creates that unre sponsive figure in the field of discursive which we have subsequently called the 'author'. The dialectical preference for question-and-answer is designed to resist anything resembling an author from entering the field of knowledge: the Socratic method resists monologism on epistemological and ethical grounds. However, the Platonic dialogues are (...) split in their signature between a Socrates who speaks and a Socrates who writes. As the Platonic oeuvre increases, so it moves from graphic representation of the oral methods of Socrates to the status of a writing in its own terms. The Phaedrus is a crucial statement in this cultural tran sition. So, far from simply condemning writing, the dialogue accepts Plato's growth as an author of written compositions and his growing sense of himself as an author. What tradition has registered as 'the Socratic problem' can be reviewed according to this competition between the orality of the master and the writerly practices of his pupil. Between dialogism and monologism, speech and writing, absence and presence, Socrates and Plato, the concept of the author is generated. The Plato of the Phaedrus wants to grasp, to theorize, this new figure emerg ing on the chirographic horizons, one whom he would recognize less in Socrates, 'Homer' or Pythagoras than in the mirror of his own text.

Catherine Rowett presents an in depth study of Plato's Meno, Republic and Theaetetus and offers both a coherent argument that the project in which Plato was engaging has been widely misunderstood and misrepresented, and detailed new readings of particular thorny issues in the interpretation of these classic texts.

This chapter examines a common objection to the philosophy of religion, namely, that it has not sufficiently embraced the injunction of Socrates to follow the argument where it leads. Although a general version of this charge is unfair, one emerging view in the field, which I call religious Mooreanism, nonetheless risks running contrary to the Socratic injunction. According to this view, many people can quickly, easily, and reasonably deflect all known philosophical challenges to their core religious outlooks, including arguments from (...) evil. This chapter argues that, in addition to being in tension with the Socratic injunction, religious Mooreanism is less plausible than traditional Mooreanism and in any case has not been adequately defended.

There are calls to expand the schema “ S knows that p ” to accommodate ways of knowing that are socially important but neglected in recent epistemology. A wider, more adequate conception of human knowing is needed that will include interested or motivated inquirers as “S,” and personal traits of persons as “ p .” Historically important treatments of knowing that accommodate these features deserve examination as part of the effort to create a broader epistemology. We find such a treatment (...) of knowing in Plato's Apology , 20 d-24 b, in which Socrates claims a bit of wisdom. We attend more carefully than others have to the concrete aspects of Socrates' encounters with interlocutors. (shrink)

In this award-winning study of the _Phaedrus_, Charles Griswold focuses on the theme of "self-knowledge." Relying on the principle that form and content are equally important to the dialogue's meaning, Griswold shows how the concept of self-knowledge unifies the profusion of issues set forth by Plato. Included are a new preface and an updated comprehensive bibliography of works on the _Phaedrus_.

In Metaphysics Γ 4-6 Aristotle argues that Protagoras is committed not just to denying the PNC, but also to asserting its contrary. In this paper, I offer an analysis of this commitment. I try to show that Aristotle is working with a specific idea in mind: a Protagoreanism ontologically linked to the flux doctrine, as Plato suggested in Theaetetus 152-160.

In this contribution, I explore the treatment that Plato devotes to Protagoras’ relativism in the first section of the Theaetetus (151 E 1–186 E 12) where, among other things, the definition that knowledge is perception is put under scrutiny. What I aim to do is to understand the subtlety of Plato’s argument about Protagorean relativism and, at the same time, to assess its philosophical significance by revealing the inextric¬ability of ontological and epistemological aspects on which it is built (for this (...) latter aspect, I refer to contemporary discussions of relativism, mainly to Margolis’ robust relativism). I then turn to Aristotle’s treatment of Protagoras’ relativism in Metaphysics Γ, sections 5 and 6, in order to show that Plato and Aristotle surprisingly share the same view as regards the philosophical content of Protagoras’ relativism (in doing so, I take position against the standard opinion among scholars that Plato and Aristotle understand Protagoras’ relativism in different, even incompatible, ways). What I ultimately aim to demonstrate is that Protagoras’ relativism, as understood by both Plato and Aristotle, is a coherent, even attractive, philosophical position. (shrink)

Reading the Timaeus as an early attempt at mathematizing natural science runs into serious difficulties. The so-called Platonic Solids are five in number, one more than the traditional 'elements'. Plato provides a proportional ratio for these elements but this ratio fails to tie in with their geometrical features. Appealing to the authority of mathematics appears to be a rhetorical move with no further consequences.
