Plato: Knowledge and Belief

This is a study of Plato's use of the character Socrates to model what philosophy is. The study focuses on the Apology, and finds that philosophy there is the love of wisdom, where wisdom is expertise about how to live, of the sort that only gods can fully have, and where Socrates loves wisdom in three ways, first by honoring wisdom as the gods' possession, testing human claims to it, second by pursuing wisdom, examining himself as he examines others, to (...) achieve a more well justified set of beliefs about how to live, and third by trying to live wisely, insofar as he can, which includes exhorting others to care about living wisely than anything else. The essay also includes some suggestions about how Plato criticizes and revises this model of philosophy outside the Apology. (shrink)

This paper provides a rigorous defense of innate true belief in the Meno, to my knowledge, the first of its kind. While several commentators have proposed innate true belief in the past, the position has never been defended or explained in detail. Instead, the most thorough discussions of Plato’s innatism have opted for different innate objects. I defend my proposal against these recent alternatives by showing that the passages often thought to imply innate knowledge can be read in other ways. (...) I then argue that they should be so read, because of an “awareness condition” Plato had on knowledge at the time. (shrink)

Under what conditions would it be paradoxical to consider the possibility of false judgment? Here we claim that in the initial puzzle of Theaetetus 187e5–188c9, where Plato investigates the question of what could psychologically cause a false judgment, the paradoxical nature of this question derives from certain constraints and restrictions about causal explanation, in particular, from the metaphysical principle that opposites cannot cause opposites. Contrary to all previous interpretations, this metaphysical approach does not attribute to Plato any controversial epistemological assumptions (...) and fits better with the text and its role within the dialectic of the dialogue.

This paper concerns Plato’s characterization of the body as the soul’s tool. I take perception as an example of the body’s usefulness. I explore the Timaeus’ view that perception provides us with models of orderliness. Then, I argue that perception of confusing sensible objects is necessary for our cognitive development too. Lastly, I consider the instrumentality relationship more generally and its place in Plato’s teleological worldview.

This is a review of: Platon: Meisterdenker der Antike by Thomas Alexander Szlezåk (review).

At the beginning of the "Phaedrus", Socrates distinguishes between two kinds of people: those who are more complex, violent and hybristic than the monster Typhon, and those who are simpler, calmer and tamer (230a). I argue that there are also two distinct types of Eros (Love) that correlate to Socrates’s two kinds of people. In the first case, lovers cannot attain recollection because their souls are disordered in the absence of self-knowledge. For the latter, the self-knowledge of self-disciplined lovers renders (...) them capable of recollecting the Forms by ordering their souls naturally. (shrink)

Plato often depicts Socrates inquiring together with an interlocutor into a thing/concept by trying to answer the “What is it?” question about that thing/concept. This typically involves Socrates requesting that his discussion partner answer the question, and usually ends in failure. There are, however, instances in which Socrates provides the sort of answer, in relation to a more familiar thing/concept, that he would like to receive in relation to a more obscure thing/concept, thus furnishing his interlocutor with an example of (...) how he would like him to answer. This chapter considers this dialectical tool by focusing on three instances of its use (Meno 73e3–76e4; Laches 191e9–192b3; Theaetetus 146e7–147c6). It argues, first, that in these instances Socrates provides true and adequate definitions of the things/concepts in question. It further argues that dialectic, for Plato, is just as much about the essences everyday things/concepts as it is about the essences of more obscure things/concepts; and that it is just as much about the meanings of the words we use to designate things, as it is about the essences of those things.

Diotima’s speech claims that philosophy ranks among the erōtica. The standard reading of this holds that erōs manifests in philosophical activity. This is puzzling. Eros has a reputation for overpowering the psyche, making reasoning impossible. The major interpretive discussion of this puzzle suggests that Diotima must therefore accept either non-rationalist philosophizing or rationalist erōs. This paper argues for an alternative. The “ancillary activities view” posits that the erōtica do not manifest erōs but are activities undertaken to achieve its telos. On (...) this view, love’s relationship to philosophy is as un-mysterious as wanting something and doing what it takes to get it. (shrink)

This paper takes a detailed look at the Republic’s Divided Line analogy and considers how we should respond to its most contentious implication: that pistis and dianoia have the same degree of ‘clarity’ (σαφήνεια). It argues that we must take this implication at face value and that doing so allows us to better understand both the analogy and the nature of dianoia.

Plato’s Pragmatism offers the first comprehensive defense of a pragmatist reading of Plato. According to Plato, the ultimate rational goal is not to accumulate knowledge and avoid falsehood but rather to live an excellent human life. The book contends that a pragmatic outlook is present throughout the Platonic corpus. The authors argue that the successful pursuit of a good life requires cultivating certain ethical commitments, and that maintaining these commitments often requires violating epistemic norms. In the course of defending the (...) pragmatist interpretation, the authors present a forceful Platonic argument for the conclusion that the value of truth has its limits, and that what matters most are one’s ethical commitments and the courage to live up to them. Their interpretation has far-reaching consequences in that it reshapes how we understand the relationship between Plato’s ethics and epistemology. Plato’s Pragmatism will appeal to scholars and advanced students of Plato and ancient philosophy. It will also be of interest to those working on current controversies in ethics and epistemology.

At Meno 87b-c, and again in the Protagoras, Socrates commits himself to the biconditional that all knowledge, and only knowledge, is teachable.

I argue that Plato believes that the soul must be both the principle of motion and the subject of cognition because it moves things specifically by means of its thoughts. I begin by arguing that the soul moves things by means of such acts as examination and deliberation, and that this view is developed in response to Anaxagoras. I then argue that every kind of soul enjoys a kind of cognition, with even plant souls having a form of Aristotelian discrimination (...) (krisis), and that there is therefore no completely unintelligent, evil soul in the cosmos that can explain disorderly motions; as a result, the soul is not the principle of all motion but only motion in the cosmos after it has been ordered by the Demiurge. (shrink)

The account of knowledge in Plato’s Theaetetus, as true belief meta logou, seems to lead to a regress, which may be avoided by defining one kind of knowledge as true belief that rests on a different kind of knowledge. I explore a specific version of this move: to define knowledge as true belief that results from a successful and proper exercise of a rational capacity (a dunamis meta logou).

In this paper, I argue that Plato's views on Forms play a central role in his educational philosophy. In response to what certain commentators have recently written, I contend that this interpretation not only is accurate but also is advantageous because of how it can help philosophy of education. I also address the view, proposed by one philosopher of education, that Plato believes that the most valuable sort of knowledge cannot be fully expressed in words and that the objects of (...) this knowledge are something other than transcendent Forms. Preferable to that view, I argue, is the idea that Plato wants knowledge of Forms which is nonrepresentational. (shrink)

This paper defends a reading of eikasia—the lowest kind of cognition in the Divided Line—as a kind of empirical cognition that Plato appeals to when explaining, among other things, the origin of ethical error. The paper has two central claims. First, eikasia with respect to, for example, goodness or justice is not different in kind to eikasia with respect to purely sensory images like shadows and reflections: the only difference is that in the first case the sensory images include representations (...) of value properties. Second, eikasia is not the bare awareness of images or simply a label for an error (mistaking image for original) but a kind of empirical, image-confined cognition, and one that has an important part to play in characterising the cognitive abilities of the non-rational parts of the soul.

Review of Catherine Rowett's Knowledge and Truth in Plato.

It is often claimed that Plato’s definition of knowledge as “true opinion with an account” is in agreement with the contemporary analysis of knowledge as “justified true belief”. Some scholars disagree with the attribution of JTB to Plato. I analyze three influential arguments against the assumption of Plato’s agreement with JTB, and refute them. Then I provide my own argument against the assumption. I argue that the contemporary interpretation of the JTB formula understands “belief” not in the sense of an (...) “opinion,” but rather of a “degree of confidence.” Accordingly, “justification” is understood not as applying to the opinion itself, but rather to the person having a certain degree of confidence. I support this claim by showing the difference between the traditional and the contemporary understanding of “evidence,” the former referring to a property of the proposition, while the latter meaning the body of reasons, which supports the person’s confidence to a certain degree. Thus, I conclude that Plato understands knowledge as “correct opinion validated by a rational explanation,” and it has very little in common with the contemporary understanding of knowledge as “sufficiently supported subjective degree of confidence in the truth of a proposition.”.

At 252e1 to 253c9 in Plato’s Sophist, the Eleatic Visitor explains why philosophy is a science. Like the art of grammar, philosophical knowledge corresponds to a generic structure of discrete kinds and is acquired by systematic analysis of how these kinds intermingle. In the literature, the Visitor’s science is either understood as an expression of a mature and authentic platonic metaphysics, or as a sophisticated illusion staged to illustrate the seductive lure of sophistic deception. By showing how the Visitor’s account (...) of the science of philosophy is just as comprehensive, phantasmatic and self-concealing as the art of sophistry identified at the dialogue’s outset, this paper argues in favor of the latter view.

This chapter [of the edited volume, A Companion to Ancient Philosophy] examines the shift in Plato’s account of the eidē or ‘forms’ from the Republic to the Parmenides. Forms in the Republic are characterized in terms of perfection, purity, and changelessness, with the form being an ultimate explanatory principle for being-X. Participants, while being-X, are also capable of not-being-X, either through qualitative change and coming-to-be, or through external changes in perspective or opinion, by which they “appear [φανήσεται]” not-X (R. V.479a7). (...) The form is treated as prior to participant and as prior to mixture with what would deny what it is. It is intrinsically changeless and not subject to changes in appearance. -/- In the Parmenides, the account of form shifts to accommodate the types of admixture demanded for combination with and division from other forms. In the Fifth Hypothesis, forms are subject to determinate “bonds of being and not-being,” which permits the form to present itself as an object of discursive knowing, being-X, -Y, and -Z, and not-being not-X, not-Y, and not-Z. Forms are still treated as pure and perfect, but now with the power of gathering together intelligible bonds of being and not-being. Thus, in the Parmenides, forms are the gathering source and the gathered terms subject to the admixture; they are that by which true speech is explained. In this chapter, I argue that the “turning of the soul from becoming to truth and being” (R. VII.525c) announced in the Republic is partially fulfilled through the account of veridical speech in the Parmenides. (shrink)

In this paper, I argue that the two versions of divided line (the first in Book VI and the recalled version in Book VII) create problems that cannot be solved — with or without the hypothesis that the objects belonging to the level of διάνοια on the divided line are intermediates. I also argue that the discussion of arithmetic and calculation does not fit Aristotle’s attribution of intermediates to Plato and provides no support for the claim that Plato had such (...) intermediates in mind when he talked about διάνοια in the Republic. The upshot of my argument is negative: even if Aristotle’s report about Plato and intermediates is correct, there is no evidence for such objects provided in the passages I review from the Republic. If they are to be found in Plato, it will have to be elsewhere that they are found. (shrink)

An account of Plato’s theory of knowledge is offered. Plato is in a sense a contextualist: at least, he recognizes that his own use of the word for “knowledge” varies – in some contexts, it stands for the fullest possible level of understanding of a truth, while in other contexts, it is broader and includes less complete levels of understanding as well. But for Plato, all knowledge, properly speaking, is a priori knowledge of necessary truths – based on recollection of (...) aspects of the Forms – and so in contemporary terms, it meets the conditions of “safety” and “adherence” (or “indefeasibility”) to the highest degree. This account is defended on the basis of the text of Meno, Phaedo, and the Republic, against some objections – especially objections that are due to Gail Fine. (shrink)

This paper examines whether Socrates provides his interlocutors with good reasons to seek knowledge of what virtue is, reasons that they are in a position to appreciate. I argue that in the Laches he does provide such reasons, but they are not the reasons that are most commonly identified as Socratic. Socrates thinks his interlocutors should be motivated not by the idea that virtue is knowledge nor by the idea that knowledge is good for its own sake, but rather by (...) the idea that knowledge is needed to recognize what to aim at. His argument reaches the potentially life-altering conclusion that we should all seek knowledge of what virtue is. It is powerful precisely because it relies on uncontroversial premises that his interlocutors could be expected to accept. In laying out this argument, I distinguish different ways in which someone could count as a teacher of virtue. At the end of the article, I situate the argument within the debate about whether virtue is teachable. (shrink)

Interpreters of Theaetetus are prone to endorse the view that a god gave Socrates maieutic skill. This paper challenges that view. It provides a different account of the skill’s origins, and reconstructs a genealogy of Socratic philosophy that begins and has its end in human experience. Three distinct origins coordinate to bring forth a radically new conception of philosophy in the image of female midwifery: the state of wonder (1. efficient origin), the exercise of producing, examining and disavowing beliefs in (...) the gradual cultivation of human nature’s lack of skill (2. material origin), and Socrates’ understanding of god’s assistance as an endorsement of his mental infertility and the benefit of a particular form of dialectical training (3. formal origin). The paper concludes by arguing that Socrates transforms philosophy into a pursuit of wisdom that has its telos in becoming like a woman. (shrink)

We examine the discussion about the definition of knowledge as true judgment accompanied by logos in Theaetetus 201c-210c, in order to ascertain which of the recent alternative interpretations is more consistent with the text. To accomplish this, we intend to analyze the text and explore in detail the secondary literature about it.

Guided by the bold ambition to reexamine the nature of philosophy, questions about the foundations and origins of Plato’s dialogues have in recent years gained a new and important momentum. In the wake of the seminal work of Andrea Nightingale and especially her book Genres in Dialogue from 1995, Plato’s texts have come to be reconsidered in terms of their compositional and intergeneric fabric. Supplementing important research on the argumentative structures of the dialogues, it has been argued that Plato’s philosophizing (...) cannot be properly assessed without considering its intellectual debts. By detailed examinations of the practical, generic and textual origins of the dialogues, it has been shown how Plato’s chosen form of philosophical inquiry is deeply influenced by traditional forms of poetry, rhetoric, sophistry, and even medicine...

_ Source: _Volume 10, Issue 2, pp 151 - 167 This paper considers the unity of Socrates’ twin apparitions of sophist and statesman, alluded to in the _Sophist_. Examining how these apparitions are at work in the _Theaetetus_, I argue that the difficulty is that of combining the nurturing or educative role of the statesman with the sophist’s practice of refutation. Beginning from Socrates’ shift in appearance early in the dialogue, I argue that the cause of this shift is Theaetetus’ (...) character, that this forces the general problem Socrates has in mind into a particular form, and that Theaetetus never fully grasps this fundamental, intractable problem. Consequently, the problem’s intractability shows why Socratic education is always refutative, and so combines the statesman and sophist’s respective arts. And because Theaetetus is the cause of Socrates’ shift, the philosopher’s appearance is always an ironic reflection of his interlocutor’s opinions: the dialogue the _Philosopher_ would have to be named the _Theaetetus_.

A puzzle about false judgement is raised in the Theaetetus (187d-200c), but not successfully answered there. On the proposed account, the confusion that explicitly vitiates Theaetetus’ final attempt to define knowledge is already at work implicitly in this puzzle. Theaetetus shares popular assumptions about knowledge (epistēmē), but also accepts that there are cognitive constraints on judgement (doxa): the puzzle arises because he fails to distinguish the one cognitive condition from the other.

This paper raises a new interpretive puzzle concerning Socrates’ attitude towards truth in the Phaedo. At one point Socrates seems to advocate that he is justified in trying to convince himself that the soul is immortal and destined for a better place regardless of whether or not these claims are true, but that Cebes and Simmias should relentlessly pursue the truth about the very same matter. This raises the question: Why might Socrates believe that he will benefit from believing things (...) about death irrespective of the truth, but that Cebes and Simmias will not? Why should they continue pursuing the truth? This paper argues that the relevant difference between Socrates and his friends is that Socrates is a fully accomplished philosopher, while his friends are not. This, I argue, makes Socrates an epistemic authority, and it is in virtue of being an epistemic authority that he is justified in not pursuing the truth about death. The upshot of this paper is that sometimes the demands of living well require that we abandon the pursuit of truth and knowledge. (shrink)

In this paper we argue that Socrates is a cognitivist about emotions, but then ask how the beliefs that constitute emotions can come into being, and why those beliefs seem more resistant to change through rational persuasion than other beliefs.

In this paper I examine the account of courage offered in Books 3 and 4 of the Republic and consider its relation to the account of courage and cowardice found in the final argument of the Protagoras. I defend two main lines of thought. The first is that in the Republic Plato does not abandon the Protagoras’ view that all cases of cowardice involve mistaken judgment or ignorance about what is fearful. Rather, he continues to treat cowardly behavior as an (...) indication that, at least at the time of action, the agent lacked correct belief about what is best and least fearful. The evidence for this view will include an argument that what it means for the thumoeides to ‘preserve what is announced by rational accounts’ in the Republic is for it to prevent the fluctuation or corruption of reasoning under the deceptive influence of appetite. Second, I will argue that the Protagoras anticipates this account of courage in important ways. In particular, it draws attention to the problematic instability of belief and adumbrates the need for something like the spirited element of our psychology. According to my interpretation, the Republic’s account of courage is an elaboration or supplementation of the Protagoras’ account, rather than a rejection of it. (shrink)

The Theaetetus is subtitled peri epistemes, on knowledge, and peirastikos, tentative. Theaetetus' three attempted definitions of knowledge, each ventured only to fail, are structured in a cascading reduction. This regress functions both negatively, as an indirect demonstration that knowledge is not definable in term of opinion or judgment, that is, knowledge is not "opinion plus," but also positively, as the ill-fated definitions build upon one another to delineate the elements necessary for a possible theory of judgment. The themes of knowledge (...) and judgment never resolve, yet, through the multiple peirastic beginnings that perish struggling to say something lasting about knowledge, this main theme ties together the dialogue's many subthemes-wisdom and character; sophistry and its relation to philosophy; Socrates' trial; intellectual midwifery, or Socratic dialectic; appearance and reality; Heracliteanism; Eleaticism; forms and participation; unity and plurality; particularity and universality; identity and difference; memory and time; relations; the relation of resemblance. One could go on. The guiding question, how to define knowledge, is a theoretical one, and the reasoning becomes progressively more abstract as the dialogue proceeds, while at the same time never straying far from practical implications: the theoretical conception of knowledge holds consequences made manifest in human action and deliberation. The dialogue about knowledge is also a dialogue about wisdom. (shrink)

I argue that Meno’s Paradox targets the type of knowledge that Socrates has been looking for earlier in the dialogue: knowledge grounded in explanatory definitions. Socrates places strict requirements on definitions and thinks we need these definitions to acquire knowledge. Meno’s challenge uses Socrates’ constraints to argue that we can neither propose definitions nor recognize them. To understand Socrates’ response to the challenge, we need to view Meno’s challenge and Socrates’ response as part of a larger disagreement about the value (...) of inquiry. (shrink)

In book 10 of the Republic we find a new argument for the division of the soul. The argument’s structure is similar to the arguments in book 4 but, unlike those arguments, it centres on a purely cognitive conflict: believing and disbelieving the same thing, at the same time. The argument presents two interpretive difficulties. First, it assumes that a conflict between a belief and an appearance—e.g. disbelieving that a stick partially immersed in water is, as it appears, bent—entails a (...) conflict between beliefs. Prima facie, there is only one belief, the belief that contradicts the appearance. Second, it is unclear what parts of the soul Plato intends to divide between: some argue that it is, as in book 4, a partition between a rational and a non-rational part; others argue that it is a new partition between a higher and a lower subdivision of the rational part. This paper offers solutions to both difficulties through an analysis of what Plato means by φαινόμενα, ‘appearances’, and δόξαι, ‘beliefs’. It is argued, first, that the relevant appearances are entirely sensory but nonetheless sufficiently belief-like to (a) warrant being called δόξαι and (b) oppose, by themselves, our beliefs; there is no need for a third mental state, a belief that assents to the appearance. A second claim concerns a central line in the argument, 602e4–6, that has served as the primary evidence that the partition is within the rational part of the soul. Those who wish to avoid this conclusion generally resort to alternative, and less natural, translations of 602e4–6. It is argued that this is unnecessary: once we have correctly understood sensory appearances, we see that the standard translation of 602e4–6 in fact entails a division between a rational and a non-rational part of the soul.

Recent critiques of veritistic value monism, or the idea that true belief is unique in being of fundamental epistemic value, typically invoke a claim about the surplus value of knowledge over mere true belief, in turn traced back to Plato's Meno. However, to the extent Plato at all defends a surplus claim in the Meno, it differs from that figuring in contemporary discussions with respect to both its scope and the kind of value at issue, and is under closer scrutiny (...) fully compatible with veritistic value monism. Consequently, contrary to what seems to be supposed in the literature, the critics of monism have little to gain from turning to the Meno for support. (shrink)

This work articulates two thesis: one Socratic and one Platonic; and displays how the first one is heir of the second. The Socratic one is called the principle of priority of definition; the Platonic one is the Recollection theory. The articulation between both theses is possible due to the Meno’s paradox, which makes a criticism on the first thesis, but it is solved with the second one. The consequence of this articulation is a new interpretation of the Recollection theory, as (...) a theory of knowledge acquisition that depends, mainly, on a distinction between knowledge and true opinion. To conclude, a new interpretation of the knowledge/true opinion distinction is displayed –not in the traditional fashion, evaluating the propositions one by one, and in an atomic way–, but as big blocks or chains of propositions shaping knowledge through explanatory reasoning (aitías logismós).

In thesophist (263e10–264b4), Plato distinguishes between two kinds of belief. On the one hand, there is a kind of belief that occurs “according to thinking” (κατὰ διάνοιαν), being “the completion of thinking” (διανοίας ἀποτελεύτησις). This kind is called ‘doxa.’ On the other hand, there is another kind of belief that occurs “through sense perception” (δι᾽ αἰσθήσεως). This kind is called ‘phantasia,’ perhaps best rendered as “appearing.”1 The purpose of this paper is to uncover the distinction between these two different kinds (...) of belief.2 What distinguishes these two kinds of belief is the believer’s understanding of the thing the belief is about, as a result of the way in which each kind of belief is ..

A claim for minimalism about ‘real’ on the model of minimalism about ‘true’. The article, in effect, develops J.L. Austin’s remark that with ‘real’, the negative ‘wears the trousers’. The development is then exploited for a proposed elucidation of Plato’s discussion of the fields of knowledge and belief in his Republic. It is proposed that Plato was striving for something whose futility was a leading theme of Wittgenstein’s later philosophy.

Since Stalbaum’s 1838 translation revived interest in Plato’s Timaeus, commentators have tended to bracket the discourse on Necessity, reading it as either mythical or mystical. This essay offers an interpretation of Necessity that is also an assertion of its importance for understanding the philosophically important conception of chora-space found therein. Beginning with throwing ourselves back into the Presocratic milieu, I examine what remains of Presocratic notions of kreon and ananke (necessity) in order to move forward a more robust interpretation of (...) the discourse on Necessity and chora-space.

I develop the relatively familiar idea of a variety of forms of knowledge —not just propositional knowledge but also knowledge -how and experiential knowledge —and show how this variety can be used to make interesting sense of Plato’s and Aristotle’s philosophy, and in particular their ethics. I then add to this threefold analysis of knowledge a less familiar fourth variety, objectual knowledge, and suggest that this is also interesting and important in the understanding of Plato and Aristotle.

Nothing could be more helpful to present philosophizing than a “Back to Plato” movement; but it would have to be back to the dramatic, restless, cooperatively inquiring Plato of the Dialogues, trying one mode of attack after another to see what it might yield; back to the Plato whose highest flight of metaphysics always terminated with a social and practical turn, and not to the artificial Plato constructed by unimaginative commentators who treat him as the original university professor. The suggestion (...) that pragmatism must return to the Platonic dialogues is an interesting one. Dewey suggests that pragmatism, and philosophy on the whole, would benefit from revisiting the “dramatic, restless,... inquiring.. (shrink)
