In Metaphysics M.2, 1077a9-14, Aristotle appears to argue against the existence of Platonic Forms on the basis of there being certain universal mathematical proofs which are about things that are ‘beyond’ the ordinary objects of mathematics and that cannot be identified with any of these. It is a very effective argument against Platonism, because it provides a counter-example to the core Platonic idea that there are Forms in order to serve as the object of scientific knowledge: (...) the universal of which theorems of universal mathematics are proven in Greek mathematics is neither Quantity in general nor any of the specific quantities, but Quantity-of-type-x. This universal cannot be a Platonic Form, for it is dependent on the types of quantity over which the variable ranges. Since for both Plato and Aristotle the object of scientific knowledge is that F which explains why G holds, as shown in a ‘direct’ proof about an arbitrary F (they merely disagree about the ontological status of this arbitrary F, whether a Form or a particular used in so far as it is F), Plato cannot maintain that Forms must be there as objects of scientific knowledge - unless the mathematics is changed.

The thesis of this paper is that Platonic Forms are angels. I make this identification by claiming that Platonic Forms have the characteristics of angels, in particular, that Platonic Forms are alive. I offer four arguments for this claim. First, it seems that engaging in self-directed action is a sufficient condition for being alive. The Forms are, as teleological activities, self-directed actions. Second, bodies receive their being from their Forms, and some bodies (...) are essentially alive. Third, in the Good, all the types of goodness, including life, are identical. The Forms are appearances of the Good. Fourth, since the Good imparts as much goodness as it can, the Forms are alive unless there is some bar to their being alive. There are good reasons to think that there is no such bar. I then show that ethical vices do not give body to human form, but give body to other forms—those that are evil angels. Lastly, I provide a survey of the relationships that various religious traditions posit between ethical vice and the demonic. (shrink)

I am interested in examining the reasoning of Plato’s extremely condensed argument in Republic X for the uniqueness of Forms. I will explore the metaphysical principles and assumptions that are supplied in the text, or need to be presupposed in order to understand the reasoning in the argument. Further, I will reflect on the truth and philosophical significance of its conclusion.

This paper provides an original approach to research on the logical processes that determine how certain forms participate in others. By introducing the concept of relational participation, the problems of self-referentiality of the Platonic forms can be dealt with more effectively. Applying this to the forms of likeness and unlikeness in Parmenides 132d-133a reveals a possible way to resolve different versions of the Third Man Argument. The method of generating numbers from oddness and evenness may also (...) be of interest; relational participation in these forms clarifies the interpretation of Parmenides 143e-144a. (shrink)

In this chapter, I make the case for platonic realism, the thesis that there are properties that lack spatial locations. After criticizing the one-over-many argument for realism and Lewis's argument for realism, I endorse a modal argument that derives the existence of platonic properties from considerations involving necessary truth. I then defend this argument from various objections. Finally, I argue that epistemic considerations and considerations of parsimony favor a weak form of platonic realism on which there are (...) platonic properties, but each property could have had an instance, and would have been located in its instances if it had any.

Die Beschäftigung mit Platon hat eine lange Geschichte, Rezeptionen seines Denkens sind so prägend für die Philosophiegeschichte geworden, dass diese verständlicherweise zuweilen als eine Sammlung von Fußnoten zu seinem Werk begriffen wurde. Das gilt besonders für einen durchgängigen metaphysischen Zug des abendländischen Denkens, ein grundsätzliches Ordnungsmodell aus der Antike, das, christlich gewendet, die Theoriebildung bis in unsere Tage fundiert. Aber mit einer Reihe anderer Gewissheiten ist auch dieser erfolgreiche Platonismus Gegenstand der Kritik geworden. Kann und soll man den metaphysischen Platon (...) retten oder muss man Platon vielmehr gegen die metaphysische Tradition neu verstehen? Muss man Platon gegen die Platonisten verteidigen, ist er der Anfang einer philosophischen Verirrung? -- Dorothea Frede, Ekkehard Martens, Arbogast Schmitt, Gernot Böhme, Hermann Schmitz, Wolfgang Detel und andere entdecken – auch durch ihre Kritik – Platon als Gesprächspartner der Gegenwart neu.

Plato's Phaedo is a literary gem that develops many of his most famous ideas. David Ebrey's careful reinterpretation argues that the many debates about the dialogue cannot be resolved so long as we consider its passages in relative isolation from one another, separated from their intellectual background. His book shows how Plato responds to his literary, religious, scientific, and philosophical context, and argues that we can only understand the dialogue's central ideas and arguments in light of its overall structure. This (...) approach yields new interpretations of the dialogue's key ideas, including the nature and existence of 'Platonic' forms, the existence of the soul after death, the method of hypothesis, and the contemplative ethical ideal. Moreover, this comprehensive approach shows how the characters play an integral role in the Phaedo's development and how its literary structure complements Socrates' views while making its own distinctive contribution to the dialogue's drama and ideas.

Limits of the Conversation about Forms. Types of Knowledge and Necessity of Forms in Plato's "Parmenides". - Forms (ideas) are among the things that Plato is serious about. But about these things he says in his "Seventh Letter": "There neither is nor ever will be a treatise of mine on the subject." (341c, transl. J. Harward). Plato's statement suggests the question, why one does not and never can do justice to the Platonic forms by means (...) of a written text about the forms. Another big question of Plato research is whether the conversations documented in the Platonic dialogues are also affected by this verdict. This paper aims to provide, as far as possible, newly substantiated answers to these two questions. To this end, the systematic limits of the discussion about forms, which are particularly evident in Plato's dialogue "Parmenides", are examined in eight steps: First, two types of knowledge are presented that play an important systematic role in Plato's philosophy with regard to the limits of conversation: knowledge-how (practical knowledge) and knowledge-that (propositional knowledge) (I). Then the Socratic model of these two types of knowledge is interpreted, which is drafted in the tenth book of the "Republic". This model uses the example of bridle, bridlemaker and rider to explain the primacy of practical knowledge and the limits of propositional knowledge (II). Subsequently, it will be shown how the dialogues "Republic" and "Parmenides" are connected with each other in content and form (III). The gradation of the two types of knowledge, which is indicated by the motifs of the bridle and the horse on the image level of the "Parmenides", proves to be the structure that systematically underlies the structure of the entire dialogue (IV). It also makes clear why the conversation about the forms in the first part of the "Parmenides" has to fail (V). The assumption that the two parts of the "Parmenides" express two different types of knowledge in dealing with forms is supported by the results of a logical analysis of the last defence of the acceptance of forms (135b-c). This analysis shows why, for reasons of principle, it is impossible to speak adequately about forms (VI). Forms have the function of being presuppositions of 'talking about something'. Thus forms are always presupposed in conversation when one talks about them, and thus elude appropriate discussion in conversation (VII). That this is not only a methodical insight of the Platonic Parmenides, but can also be attributed to Plato himself, is demonstrated by the concluding reinterpretation of the central sentence of the critique of writing in Plato's "Seventh Letter". It will become apparent that, contrary to the now widespread view of the representatives of the Tübingen school, philosophical and also good philological reasons speak for the fact that Plato related his criticism only to the communicability of forms through treatises, i.e. tract-like writings (VIII).

The scope of Platonism is extended by introducing the concept of a “Platonic computer” which is incorporated in metacomputics. The theoretical framework of metacomputics postulates that a Platonic computer exists in the realm of Forms and is made by, of, with, and from metaconsciousness. Metaconsciousness is defined as the “power to conceive, to perceive, and to be self-aware” and is the formless, con-tentless infinite potentiality. Metacomputics models how metaconsciousness generates the perceived actualities including abstract entities and physical (...) and nonphysical realities. It is postulated that this is achieved via digital computation using the Platonic computer. The introduction of a Platonic computer into the realm of Forms thus bridges the “inverse explanatory gap” and therefore solves the “inverse hard problem of consciousness” in the philosophy of mind.

David Armstrong accepted the following three theses: universals are immanent, laws are relations between universals, and laws govern. Taken together, they form an attractive position, for they promise to explain regularities in nature—one of the most important desiderata for a theory of laws and properties—while remaining compatible with naturalism. However, I argue that the three theses are incompatible. The basic idea is that each thesis makes an explanatory claim, but the three claims can be shown to run in a problematic (...) circle. I then consider which thesis we ought to reject and suggest some general lessons for the metaphysics of laws. (shrink)

Following the structuring hints given by Plato in his Timaeus you find, that the dialogue – actually Timaeus' lecture – falls in two parts, not in three as Cornford, Brisson and others suggest. The main division follows the two invocations of the gods (27c, 48d). The first part presents the world in its noetic form, poetically described as the work of the demiurg. Timaeus opens this part giving first his premises in the form of an introduction, which lead his presentation. (...) At the end of this part he remarks that the given premises are not enough for his aim, to explain the nature of man. Therefore he adds other guiding principles for the second part in form of a second introduction like in the first part. We need a third principle beside the real beings (the ideas) and the things we perceive. He names it chora and the new form of "`causation"' ananke, necessity. These supplementary principles anable Timaeus to describe the world under our everyday conditions, they mediate the noetic world with the world of our senses. Here is the point we can see a surprising parallel in Kant's work. The Metaphysische Anfangsgründe der Naturwissenschaft correspond to the first part of the Timaeus, because here Kant exposes too the metyphysical foundation of the sciences. Later, in his last years he remarks, that there is a gap between these metaphysical principles and the physics (say of Newton or other). He seeks for a mediating principle and finds it in the "Äther" or "Wärmestoff." Kant was no more able to bring his idea to an end, we only have a lot of variating attempts, named by editors Opus postumum. But the aim of them is clear – and near by the aim that Plato aimed at – to mediate the noetic structure of the world with our everyday world. And this is evidently equivalent with the second introduction in the Timaeus. -/- Here some pages of the book-version: Erwin Sonderegger, Zur Funktion der Chora in Platons Timaios und des Äthers in Kants Übergangsschrift, Königshausen & Neumann, Würzburg 2015.

This paper provides a rational reconstruction of a Platonic trope bundle theory that is a live alternative to contemporary bundle theories. According to the theory, Platonic particulars are composed of what Plato calls images of Forms; contemporary metaphysicians call these tropes. Tropes are dependent on Forms and the Receptacle, while trope bundles are structured by natural kinds using the Phaedo's principles of inclusion and exclusion and the Timaeus’ geometrised elements, as well as by co-location in the (...) Receptacle. Key elements of discussion include persistence and abundance of Plato's tropes. The resulting theory is compared with contemporary trope bundle theories. (shrink)

In this note I examine the two main differences between Plato's and Dennett's views of the self as an abstract object. I point out that in the presence of certain forms of ontological realism, abstract-object theories of the self are compatible with the full reality of the self. I conclude with some remarks on the relationship between ontology and ethics.

this paper offers a new interpretation of Phaedo 96a–103a. Plato has devoted the dialogue up to this point to a series of arguments for the claim that the soul is immortal. However, one of the characters, Cebes, insists that so far nothing more has been established than that the soul is durable, divine, and in existence before the incarnation of birth. What is needed is something more ambitious: a proof that the soul is not such as to pass out of (...) existence. According to Socrates’s initial response to Cebes at 95e8–96a1, giving such a demonstration requires a thorough investigation into “the reason for coming to be and passing away in general” (ὅλως γὰρ δεῖ περὶ γενέσεως καὶ φθορᾶς τὴν αἰτίαν διαπραγματεύσασθαι 95e9–96a1). This leads Socrates to the passage with which this paper is concerned. He mentions several changes of different sorts and nominates some purported “causes” that he and other theorists used to accept, but which he now finds scarcely intelligible. He then expounds his own mature view that the Forms are causes. The existing literature on this passage is vast and highly sophisticated, so much so that one might reasonably despair of saying something new at this stage. Nevertheless, I think some of Socrates’s remarks on philosophical methodology in our passage have not yet been appreciated as deeply as they should be. In particular, there has been little work showing how well-integrated they are with his positive proposals about causes. I also think that there are metaphysical models available to modern philosophers, not merely coherent with but actually suggested by Socrates’s methodology, which give a more satisfactory picture of those positive proposals than others available in the contemporary literature. That, at any rate, is what this paper aims to provide. (shrink)

Since 1976, when Thomas A. Szlezák held his inaugural lecture as a private lecturer at the University of Zurich entitled "The Dialogue Form and Esotericism: On the Interpretation of the Platonic Dialogue the Phaedrus", the now-emeritus professor at Tübingen has advocated a particular interpretation of the Platonic dialogues and especially of the Phaedrus: namely, that what is referred to in the latter dialogue—without further explanation—as "more valuable" than what is set down in writing corresponds to Plato's "so called (...) unwritten doctrines", or for Szlezák, "unwritten...

Platon s-a inspirat din activitatea filosofică a unora dintre predecesorii săi, în special a lui Socrate, dar și Parmenide, Heraclit și Pitagora, pentru a-și dezvolta propria filosofie, care explorează majoritatea domeniilor importante, inclusiv metafizica, etica, estetica și politica.Împreună cu profesorul său Socrate și elevul său Aristotel, a pus bazele gândirii filosofice occidentale. Platon este considerat ca unul dintre cei mai importanți și influenți filosofi din istoria omenirii, fiind unul dintre fondatorii religiei și spiritualității occidentale. Filosofia dezvoltată de el, cunoscută sub (...) numele de platonism, se bazează pe teoria Formelor cunoscută prin rațiune pură ca soluție la problema universalelor. Filosofia lui Platon se înscrie pe linia presocraticilor, a sofiștilor și a tradițiilor artistice care stau la baza educației grecești, într-un cadru nou, definit de dialectică și teoria ideilor. Cunoașterea este pentru Platon o activitate a sufletului, afectată de obiectele sensibile, și de procesele interne. În Republica, forma cea mai înaltă este considerată ca fiind Forma Binelui, sursa tuturor celorlalte Forme care ar putea fi cunoscute prin rațiune. Tema centrală a cărții este dreptatea, argumentată cu ajutorul mai multor teorii platonice, inclusiv mitul alegoric al peșterii, doctrina ideilor, dialectica, teoria sufletului și proiectul unui oraș ideal. Dialectica lui este un tip de cunoaștere, cu rol rol ontologic și metafizic, la care se ajunge prin confruntarea mai multor poziții pentru a depăși opinia (doxa), o deplasare din lumea aparențelor (sau a „sensibilului”) către cunoașterea intelectuală (sau „inteligibilul”) până la primele principii. Modelul educațional al lui Platon (paidèia) diferențiază nivelul educației în funcție de aptitudinile elevilor. Conform principiilor socratice, pentru a face dreptate trebuie să se știe ce este bine, iar aceasta o știe cel mai bine filosoful. Platon a detaliat acest concept, evidențiind distincția dintre filosof (care caută principiile adevărului fără a pretinde că îl posedă) și sofist (care se lasă ghidat de opinie ca singurul parametru valid al cunoașterii). -/- CUPRINS -/- Platon - Biografie - Călătoriile lui Platon - Socrate - Academia - Lucrările lui Platon - - Clasificări ale lucrărilor - - - Cronologic - - - Tetralogii - - - Trilogii - - - Grupări lexicale Filosofia lui Platon - Sufletul - Funcția mitului - Idei - Teoria formelor - Ontologia - Epistemologia - Etica - Politica - Statul filosofic - Arta - Doctrinele nescrise: Unu și Diada Republica - Personaje - Conținut - Temele Republicii - - Justiția și dreptatea (Cartea I) - - Statul ideal (Cărțile II-III) - - Analogia oraș-suflet.

This paper investigates Newton’s ontology of space in order to determine its commitment, if any, to both Cambridge neo-Platonism, which posits an incorporeal basis for space, and substantivalism, which regards space as a form of substance or entity. A non-substantivalist interpretation of Newton’s theory has been famously championed by Howard Stein and Robert DiSalle, among others, while both Stein and the early work of J. E. McGuire have downplayed the influence of Cambridge neo-Platonism on various aspects of Newton’s own spatial (...) hypotheses. Both of these assertions will be shown to be problematic on various grounds, with special emphasis placed on Stein’s influential case for a non-substantivalist reading. Our analysis will strive, nonetheless, to reveal the unique or forward-looking aspects of Newton’s approach, most notably, his critical assessment of substance ontologies, that help to distinguish his theory of space from his neo-Platonic contemporaries and predecessors.

A standard interpretation of Plato’s metaphysics holds that sensible particulars are images of Forms. Such particulars are fairly independent, like Aristotelian substances. I argue that this is incorrect: Platonic particulars are not Form images but aggregates of Form images, which are property-instances. Timaeus 49e-50a focuses on “this-suches” and even goes so far as to claim that they compose other things. I argue that Form images are this-suches, which are tropes. I also examine the geometrical account, showing that the (...) geometrical constituents of the elements are also Form images. Thus everything in the sensible world is composed of tropes. (shrink)

Although St. Albert the Great is known for his assimilation of Aristotle’s thought, he holds Plato in high regard. Yet Aristotle largely guides Albert’s understanding of Plato and Aristotelian criticism against him is repeated along Albert’s work. The objections raised in the first book of the Metaphysics are especially recurrent. Therefore to study Albert’s commentary on such objections in some detail, as we do in these pages, has considerable interest. Criticism against Plato focuses on his conception of the universal and (...) the separation of ideas. Moreover, Albert assimilates several platonic doctrines because, like many other Christian authors, he sees in the Timaeus a metaphysical approach, which is susceptible to be combined with his faith. Albert also believes to find a substantial agreement between the views of Plato and Aristotle at various points, including the question of form, despite differences in their expositions. (shrink)

La philosophie de Platon s'inscrit dans la lignée des présocratiques, des sophistes et des traditions artistiques qui sous-tendent l'éducation grecque, dans un cadre nouveau, défini par la dialectique et la théorie des Idées. Pour Platon, la connaissance est une activité de l'âme, affectée par des objets sensibles, et par des processus internes. Le platonisme a ses origines dans la philosophie de Platon, bien qu'il ne doive pas être confondu avec elle. Selon le platonisme, il existe des objets abstraits (une notion (...) différente de celle de la philosophie moderne qui existe dans un autre domaine distinct à la fois du monde sensible externe et du monde interne de la conscience, et est à l'opposé du nominalisme). Une distinction essentielle pour Platon dans sa philosophie est la théorie des Formes, la distinction entre la réalité perceptible mais inintelligible (science) et la réalité imperceptible mais intelligible (mathématiques). La géométrie était la principale motivation de Platon, ce qui montre l'influence de Pythagore.

The principle of performative contradiction. On the epistemological significance of the dialogue form in Plato's "Euthydemus". - In this study, an analysis of the section 285d-288a of Plato's "Euthydemus" shall show two things: (1) The sophistic model of a world in which there is no contradiction, in which every linguistic utterance is true and every action correct, has no semantic inconsistencies, but can only be rejected with the help of the principle of performative contradictions. (2) It is precisely these performative (...) contradictions that make it necessary for Plato to philosophize not in treatises but in dialogues; in other words, that the philosophical relevance of the Platonic form of dialogue can be seen, among other things, in the fact that - in contrast to philosophical forms of representation such as the treatise, the essay, and a henology as reconstructed and represented by the Tübingen School - it permits the representation of performative reflections and performative contradictions.

La dialectique, un processus qui nous conduit à la connaissance des Formes et finalement à la Forme la plus élevée du Bien, à travers la discussion, le raisonnement, les questions et l'interprétation, a préoccupé les philosophes depuis les temps anciens. Socrate pratiquait la dialectique par la méthode du dialogue oral, qu'il appelait l'art de « la naissance des âmes » (méthode aussi appelée maya, ou méthode d'Elenchus), qui pouvait conduire, selon l'intention de Socrate, à confirmer ou infirmer déclarations, ou à (...) la soi-disant « aporie » dans laquelle aucune conclusion définitive n'a été tirée. Chez Platon, la dialectique est un type de connaissance, avec un rôle ontologique et métaphysique, auquel on accède en confrontant plusieurs positions pour dépasser l'opinion (doxa), un passage du monde des apparences (ou « sensible ») à la connaissance intellectuelle (ou « intelligible ») aux premiers Principes. Il implique également l'ordonnancement des concepts en genres et espèces par la méthode de la division, et embrasse la multiplicité dans l'unité, étant utilisé pour comprendre l'ensemble du processus d'illumination, par lequel le philosophe est éduqué afin d'atteindre la connaissance du bien suprême, le Forme du bien. -/- DOI: 10.13140/RG.2.2.30743.85925 .

In Plato’s dialogues, Socrates calls things like justice, piety, and largeness “forms.” In several of these dialogues, he makes clear that forms are very different from familiar objects like tables and trees. Why, exactly, does he think that they differ and how are they supposed to do so? This chapter argues that in the Phaedo Socrates does not assume that they are different, but rather, over five stages of the dialogue, provides an account of how and why they (...) do so. To fully understand the claims made in the first stage, one must look to the next stage, and so on until the final stage. Socrates' ultimate reason for distinguishing forms from ordinary objects does not depend on our intuitions about things like justice and largeness, nor on the distinction between universals and particulars. Ultimately, forms cannot be ordinary objects because the form of f-ness must cause every f-thing to be f, but no ordinary object could serve as such a cause. They cannot do so because they have multiple parts and are receptive of opposites; by contrast, the form of f-ness must be simple and unchanging, since it causes every f-thing to be f. (shrink)

Cette étude cherche à rendre compte d’un trait particulier et pratiquement inobservé dans la fondation gadamérienne de l’herméneutique philosophique. Si l’on connaît bien le rôle du platonisme — et plus spécifiquement du dialogue platonicien — parmi les sources au sein desquelles Gadamer a puisé pour formuler le caractère dialogique du comprendre, on a rarement noté que la phénoménologie du dialogue sur laquelle s’appuie une telle fondation s’inscrivait en faux par rapport à son modèle sur un point bien précis : l’ironie, (...) qu’elle soit socratique ou platonicienne. Nous proposons ici que pour bien expliquer la relation trouble que la fondation dialogique de l’herméneutique gadamérienne entretient avec l’ironie socratico-platonicienne, il faille concevoir le platonisme de Gadamer à la lumière d’une certaine forme d’aristotélisation, par laquelle la philia et la phronêsis aristotéliciennes sont en quelque sorte projetées sur le modèle platonicien du dialogue.

One Stoic response to the skeptical indistinguishability argument is that it fails to account for expertise: the Stoics allow that while two similar objects create indistinguishable appearances in the amateur, this is not true of the expert, whose appearances succeed in discriminating the pair. This paper re-examines the motivations for this Stoic response, and argues that it reveals the Stoic claim that, in generating a kataleptic appearance, the perceiver’s mind is active, insofar as it applies concepts matching the perceptual stimulus. (...) I argue that this claim is reflected in the Stoic definition of the kataleptic appearance, and that it respects their more general account of mental representation. I further suggest that, in attributing some activity to the mind in creating each kataleptic appearance, and in claiming that the expert’s mind allows her to form more kataleptic appearances than the amateur, the Stoics draw inspiration from the wax tablet model in Plato’s Theaetetus (190e–196d), where Socrates distinguishes the wise from the ignorant on the basis of how well they match sensory input with its appropriate mental ‘seal’ (σφραγίς).

Conceptualism—the view that universals are mental entities without an external, independent, or substantial reality—has enjoyed popularity at various points throughout the history of philosophy. While Plato’s Theory of Forms is not a conceptualist theory of universals, we find at Parmenides 132b–c the startling conceptualist suggestion from a young Socrates that each Form might be a noēma, or a mental entity. This suggestion and Parmenides’ cryptic objections to it have been overshadowed by their placement directly after the notoriously difficult Third (...) Man Argument, and before the Likeness Regress. However, in the background of 132b–c, we find illuminating assumptions behind Parmenides’ arguments against the Theory of Forms in the first half of the dialogue. We also find in this text a set of implied criteria for Platonic concepthood. While in the Platonic corpus, Forms are explanantia for many of the phenomena explained by concepts in contemporary philosophy, concepts do seem to have an important epistemic role in Plato’s philosophy. An account of Platonic concepthood therefore opens the door for new ways of understanding the Platonic corpus as a whole. My focus in this paper is to uncover these assumptions and criteria through a close reading of Socrates’ conceptualist suggestion and Parmenides’ truncated objections to it at Parmenides 132b–c.

Die besondere Form von Platonischer Unterdrückung – durch die bestimmte Wünsche in Sklaverei gehalten werden, so dass sie ihre Befriedigung normalerweise nur im Traum erreichen -, scheint mit dem Freudschen Konzept der Verdrängung vereinbar, insofern sowohl der Zustand der unterdrückten Wünsche als auch der intrapsychische Ort ihrer Versklavung unter Anwendung von Freuds Konzept des Unbewussten deutbar ist.

This paper compares two influential but conflicting contemporary models of politics as an activity: those of Hannah Arendt and Alain Badiou. It discovers the fundamental difference between their approaches to politics in their opposing evaluations of the contemporary political significance of the legacy of Plato, Platonism, and the Platonic Idea. Karl Popper’s and Arendt’s analyses of the inherently ideological nature of totalitarianism are contrasted with Badiou’s vindication of an ideological “politics of the Idea.” Arendt and Badiou are shown to (...) share an understanding of politics as a realm for the human deployment of novelty and world-transformation. Their key disagreement concerns the form of activity that accomplishes this deployment. For Arendt, political activity has the basic form of noninstrumental and nonteleological action (praxis), devalued by the Platonic tradition of political philosophy. Badiou, by contrast, follows Plato in regarding politics essentially as a process of production (poiēsis) oriented to an ideal end. (shrink)

Forms of justification. On the structure and scope of self-refutation arguments in Plato, Cicero and Apel. - In this essay, the structure and scope of transcendental types of argumentation are analyzed, compared and criticized on the basis of the reception of two antiskeptical types of reasoning in ancient philosophy (Plato, Parmenides 135b-c; Cicero, Lucullus § 28) by a contemporary philosophical author (Karl-Otto Apel). Plato puts forward a transcendental argument for the inevitability of a final knowledge. Cicero argues that a (...) principle of fallibilism occurring with universal claim contradicts itself. In Karl-Otto Apel's transcendental pragmatic variant of philosophy, the two types of self-refutation arguments developed in Plato's and Cicero's dialogues are brought together into a single argumentation.

“Free will” puzzles are failed attempts to make freedom fit into forms of science. The failures seem puzzling because of widespread beliefs that forms of science describe and control everything. Errors in such beliefs are shown by reconstruction of forms of “platonic science” that were invented in ancient Greece and that have developed into modern physics. Like platonic Ideas, modern Laws of Physics are said to exercise hegemonic control through eternal, universal principles. Symmetries, rigidity and (...) continuity are imposed through linear forms that have been abstracted from geometry and indifference. Static and quasi-static forms presume placid equilibrium conditions and relaxation processes. Such forms, based on empty space, fail to describe actual material transformations that occur during the making of steel or the generation of snowflakes. They also fail to describe muscular movements and related bodily feelings of persons and animals that have actual life. Limitations of platonic science are overcome by means of new forms with the character of time, such as “beats” and saccadic, jumpy forms. New technologies of action and freedom generate and control temporal forms in proposed device models of brains and muscles. Some temporal forms have critical moments of transformation, resembling moments when persons exercise freedom, e.g., a moment of overtaking during a footrace or a moment of decision by a jury during a civil trial.

This paper is a critical investigation about the historical origins of two contemporary approaches in ethics: moral particularism and moral generalism. Moral particularism states that there are no defensible moral principles and that moral thought doesn’t consist in the application of moral principles to cases, but in understanding the morally relevant features of an action, which vary from case to case. In opposition, moral generalism is the traditional claim that moral decisions are made by applying general rules to particular actions. (...) Plato is often seen as a moral generalist for his appeal to Forms which are universal standards, while Aristotle is regarded as a precursor of moral particularism for stressing the importance of the “the prudence”, which is the intellectual capacity to perceive the irreducible specificity of a context, and the importance of “the means” which differs from person to person. First I will take Plato into discussion, and I will briefly reconstruct his theoretical account on Justice and virtue in order to establish his “generalist” orientation. Then I will analyze Aristotle’s alleged particularism by appealing to his texts and assessing some considerations of a few contemporary authors. At the end of the paper, I will question both particularism and generalism for the appropriation of the two ancient philosophers, on the ground that modern moral philosophy which is an action centered ethics is hard to reconcile with ancient moral thought which was an agent centered one.

Plato’s theory of virtue in the Laws could be striking for someone who is more familiar with Aristotle’s ethics for conceptual complementarity between the two positions (contrary emotions, the ordering element of reason, virtue as a mean which lies between two forms of vice, typically linked to excessive actions, etc.). Plato’s theory, however, still differs from that of Aristotle in two crutial points. First, the source of emotional dynamism is, according to Plato, supraindividual as far as the psyche is (...) a cosmological principle. Only if it comes to be formed and ordered, it separates from the universal cosmic context and make up the emotional nature of an individual soul. But the soul is not, and this is the second point of difference, ordered by some external element (training or education, organized by a rational agent). Plato counts on a pre-arranged order of emotions at a particular ontological topos of the individual soul into which reason eventually descends. Emotions, on their part, seem to include a nexus between formable and forming that is chronologically and methodocally prior to that between the biological substratum and its rational organization, as assumed by Aristotle.

My aim in this paper is to draw Plotinus and Derrida together in a comparison of their respective appropriations of the famous “receptacle” passage in Plato's Timaeus (specifically, Plotinus' discussion of intelligible matter in Enneads 2.4 and Derrida's essay on Timaeus entitled “Kh ō ra”). After setting the stage with a discussion of several instructive similarities between their general philosophical projects, I contend that Plotinus and Derrida take comparable approaches both to thinking the origin of the forms and to (...) problematizing the stability of the sensible/intelligible opposition. With these parallels in focus, I go on to explain how examining such points of contact can help us to dismantle the canonical constructs of “Plotinus the metaphysician” and “Derrida the anti-metaphysician” that have obscured important connections between Neoplatonism and deconstruction, and suppressed latent resources within the Platonic tradition itself for deconstructing the dualistic ontology of so-called “Platonic metaphysics.”.

In his commentary on Aristotle's Metaphysics, Alexander of Aphrodisias quotes from Aristotle's now-lost work On the Ideas -- his account of the arguments offered by Plato for the theory of Forms and his criticisms of those arguments. This paper considers one of these arguments, the Argument from Relatives (ta pros ti). It considers how Plato argued for Forms or Ideas such as the Large Itself, the Just Itself and so on and whether Plato supposed that there were (...) class='Hi'>Forms corresponding to sortal terms like Man.

Contemporary platonism has been conditioned in large part by two dogmas. One is the belief in a fundamental cleavage between intelligible but invisible Platonic forms that are real and eternal, and perceptible objects whose confinement to spacetime constitutes an inferior existence and about which knowledge is impossible. The other dogma involves a kind of reductionism: the belief that Plato’s unhypothetical first principle of the all is identical to the form of the good. Both dogmas, I argue, are ill-founded.

This paper examines a variety of approaches in order to make sense of the doctrine of divine simplicity. Discussing the implications of traditional and contemporary philosophical concepts of divine simplicity, the author argues for taking the divine nature as a stupendous substance to serve as the one and only truthmaker of statements regarding God, while we can resolve the predication problem which is caused by the idea that, as implied by divine simplicity, God is identical to his attributes if we (...) conceive of the divine nature as an equivalent to Platonic forms.

In the opening chapter of the Monologion, Anselm offers an intriguing proof for the existence of a Platonic form of goodness. This proof is extremely interesting, both in itself and for its place in the broader argument for God’s existence that Anselm develops in the Monologion as a whole. Even so, it has yet to receive the scholarly attention that it deserves. My aim in this article is to begin correcting this state of affairs by examining Anslem’s proof in (...) some detail. In particular, I aim to clarify the proof’s structure, motivate and explain its central premises, and begin the larger project of evaluating its overall success as an argument for Platonism about goodness.

In his rich and suggestive paper, Alvaro Vallejo argues for the novel thesis that Plato posits a form of pleasure in the Republic and the Philebus. Vallejo argues that the notion of a Platonic form of pleasure best explains other things that Plato says about pleasure. First, Plato draws a distinction between true pleasure and the appearance of pleasure. Second, Plato uses the same language to describe the relationship between forms and their inferior instantiations as he uses to (...) describe the relationship between true and false pleasures. In these comments, I argue that we do not need to posit a form of pleasure to explain these features of the text. Moreover, I argue that on Vallejo’s account of the form of pleasure, the form could not do the job required of it, namely, it could not explain the problem with false pleasures. (shrink)

In this essay, our goal is to discover science in Martin Heidegger's Introduction to Metaphysics, lecture notes for his 1935 summer semester course, because, after all, his subject is metaphysica generalis, or ontology, and this could be construed as a theory of the human brain. Here, by means of verbatim quotes from his text, we attempt to show that indeed these lectures can be viewed as suggestion for an objective scientific theory of human perception, the human capacity for deciphering phenomena, (...) ie. hermeneutics in its broadest sense. His added notes from the 1953 edition, all of which are comments, not corrections, imply that he never abandoned these thoughts on metaphysics, despite all of his utterances about a need to overcome it, and their popular interpretations to that effect. In his presentation, he further develops the colorful and intuitive style, an hermeneutic language, that he had created in his earlier work Being and Time. Of human existence he speaks in such expressions as being-there -- ``Dasein" -- and being-in-the-world, the latter term no longer explicit in the 1935 lectures. The lectures can be read as a pre-scientific analysis of how man, being-there, perceives his environment, artfully managing to deal with the manifold challenges posed by the phenomenal structures of the universe. Man attentively recognizes and deciphers their pre-linguistic contents and, while trying to make sense of it all, puts into words his awareness. There are numerous passages in Heidegger's work where he in fairly concrete terms provides us with hints for a perceptive science that, as it turns out and is demonstrated below in this essay, can be explained in terms of recent advances in neuroscience. It would be implausible, even unthinkable, unimaginable, for there not to be found essential agreement between on one hand his philosophical insights gained by hermeneutics of Dasein, into how our brain functions to let us know what's happening & on the other hand, scientific discoveries obtained through anatomy, EEG, fMRI, TMS, electrode implants, etc, of brain structures & functions employed in perception of the momentary scene. A nexus between science and philosophy is provided in Heidegger's definitive treatment of the Logos, here interpreted as a structural version of Platonic forms (Burchard, 2014). This allows for neurolinguistic brain functions to serve as meta-context for Heidegger's being-in-the-world. The logical functions of Dasein's anatomical brain are performed by the logos machine, formerly the human soul, using top-down processing based on a global context, the noumenal cosmos which humans maintain internally. Heidegger's 1942/43 winter semester lectures Parmenides extend in unbroken fashion his 1935 work, proving that he never abandoned, as is widely claimed, his metaphysical avenue of thought. (shrink)

Looking at every sense this article proves through deduction; that your mind needs a source to dream. Dreams are old experienced essences of platonic forms. You can only experience new forms essences when you are awake because of initial experiences. If dreams are old, experienced essences (what this article proves) therefore you know you are awake when you initially sense new experienced essences.

In this paper, drawing on evidence internal to the Platonic dialogues (supplemented with some ancient testimonia), I answer the question, “How did Plato teach in the Academy?” My reconstruction of Plato’s pedagogy in the Academy is that there was a single person who read the dialogue aloud like a rhapsode (this is in contrast to the dramatic theatrical hypothesis, in which several speakers function as actors in the performance of a dialogue). After the rhapsodic reading, students were allowed to (...) ask that portions of the text to be re-read, to ask a question about the text, and were encouraged to enter into a broader conversation about the topic and themes brought out by the text. This later pedagogical method of interrogating and investigating a dialogue is of more importance than the mere reading of a dialogue. I contend that Plato’s experiences teaching were woven into some of the dialogues, and that Plato’s pedagogy reflects some of the ways that he taught in the Academy. I propose that excellent points made by students may have been written into revised forms of the dialogue. And not only good points, but also mistakes in reasoning may have been added into the dialogues. I suggest that the way certain dialogues are organized with “guest lecturers” and “tag-team” philosophical debates reflect Plato’s pedagogy in the Academy. Plato’s broadmindedness, his openness to various and opposing viewpoints, is also evident from both outside and inside of the dialogue. Lastly, drawing on the idea of Socratic mimēsis, I give a plausible curriculum for how Plato may have used the dialogues to teach them: he had his students “play” with them. Plato may have asked his students to enter into the roles of the characters in the dialogues to better understand them and the type of person they represent. Plato may have also asked students to take over from the position of the character in the dialogue and to suggest a better, truer account of things than what the characters said or did. (shrink)

There are at least two discussions about Pythagoreans in Aristotle’s works that can be related to paradigm, both in Book A of Metaphysics. In the first, Aristotle says that for Pythagoreans all the things are modeled after numbers (τὰ μὲν ἄλλα τοῖς ἀριθμοῖς ἐφαίνετο τὴν φύσιν ἀφωμοιῶσθαι πᾶσιν). (Met., A, 985b32-33) In the second, Aristotle tells us that Pythagoreans take ‘the first subject of which a given term would be predicable (ᾧ πρώτῳ ὑπάρξειεν ὁ λεχθεὶς ὃρος)’ as the substance of (...) the thing. His example is double and two: since two is the first thing of which double is predicated, double will be the substance of two. (Met., A, 987a22-25) 1) Forms as paradigms Some of the critiques of platonic Forms in Aristotle’s works are paradigm-oriented: they attack Plato’s theory on the basis that Platonians considered Forms as paradigms. The core of all Aristotle’s objections is that calling Forms paradigms is a mere poetical strategy and does not have any real effect. (Met., 991a20-22; M, 1079b24-26) We can recognize four reasons for Aristotle’s objections of forms as paradigms: a) To consider something as the paradigm of another thing to which it is like does not have any ontological effect: ‘For what it is that works, looking to the ideas? Anything can either be, or become, like another without being copied from it, so that whether Socrates exists or not a man might come to be like Socrates.’ (Met., A, 991a22-26; M, 1079b26-29) Therefore, paradigms are ontologically unnecessary: ‘It is quite unnecessary to set up a form as a paradigm … the begetter is adequate to the making of the product and the causing of the form in the matter.’ (Met., Z, 1034a2-5) Don’t these cases imply that Aristotle did have more the ontological necessity of paradigm in thought instead of its epistemological necessity? b) To consider Forms as paradigms means that a thing must have several paradigms; e.g. animal and too-footed and man will be paradigms of the same thing. (Met., A, 991a27-29; M, 1079b31-33) c) The theory that Forms are paradigms not only of sensible things but also of themselves makes the same thing both a paradigm and a copy (ἐικών). (Met., A, 991a29-b1; M, 1079b33-35) 2) Reasoning by paradigm Aristotle compares the arguments using paradigms to his own theory of syllogism: ‘We have an ‘example’ (παράδειγμα) when the major term is proved to belong to the middle by means of a term which resembles the third. It ought to be known that the middle belongs to the third term, and that the first belongs to that which resembles the third. For example, let A be evil, B making war against neighbors, C Athenians against Thebians, D Thebians against Phocians. If then we wish to prove that to fight against Thebians is an evil, we must assume that to fight against neighbors is an evil. Evidence of this is obtained from similar cases, e.g. that the war against the Phocians was an evil to Thebians. …Now it is clear that B belongs to C and to D (for both are cases of making war upon one’s neighbors) and that A belongs to D (for the war against the Phocians did not turn out well for the Thebians); but that A belongs to B will be proved through D.’ (PsA., B, 24, 66b38-69a11) An ‘example’ can also be made by several similar cases. (PrA., B, 24, 69a11-13) Aristotle notes (PrA., B, 24, 69a13-24) that reasoning by paradigm is ‘neither like reasoning from part to whole nor like reasoning from whole to part but is rather a reasoning from part to part, when both particulars are subordinate to the same term, and one of them is known.’ And it differs from induction in two ways: a) While induction uses all the particular cases to prove that the major term belongs to the middle, reasoning by paradigm does not draw its proof from all the particular cases. b) While induction does not apply the syllogistic conclusion to the minor term, reasoning by paradigm does make this application. (PrA., B, 24, 69a13-24) . (shrink)
