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.

I contend there exists a platonistic good that all other good (excellent) things must resemble, supplementing this theory with Aristotelian features. Something’s goodness holds in virtue of the thing’s own properties being such as to satisfy its kind-based standards, and those K-standards resembling the platonic good. As for the latter condition, the K-standards resemble it firstly with respect to requiring activities, and secondly also at the level of what teleology those activities are directed towards.

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.

Principala sursă biografică despre Platon, după mărturia neoplatonicului Simplicius, ar fi fost scrisă de discipolul Xenocrate, dar din păcate nu a ajuns la noi. Cea mai veche biografie a lui Platon care a ajuns până la noi, De Platone et dogmate eius, este a unui autor latin din secolul al II-lea, Apuleius. Toate celelalte biografii ale lui Platon au fost scrise la peste cinci sute de ani de la moartea sa.

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.

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.

Psiche sets up a close-knit comparison between the psychology of Plato's Republic and Freud's psychoanalysis. Convergences and divergences are discussed in relation both to the Platonic conception of the oneiric emergence of repressed desires that prefigures the main path of Freud's subconscious, to the analysis of the psychopathologies related to these theoretical formulations and to the two diagnostic and therapeutic approaches adopted. Another crucial theme is the Platonic eros - the examination of which is also extended to the Symposium and (...) Phaedrus - taken up explicitly by Freud in relation to the concept of libido. Finally, the author also addresses the two themes - of, inter alia, a metapsychological nature - inherent to the moral dimension. -/- Psiche istituisce un confronto ravvicinato tra la psicologia della "Repubblica" di Platone e la psicoanalisi di Freud.

Altro tema cruciale è l'eros platonico - la cui disamina viene estesa anche al "Simposio" e al "Fedro" - ripreso esplicitamente da Freud in relazione al concetto di libido.

The Handmaid’s Tale depicts a United States taken over by a fundamentalist dictatorship called Gilead that also resembles Plato’s ideal city. Attempts to explain Gilead’s debt to Plato face two challenges. First, aspects of Gilead that recall Plato also contain features that differ, at times dramatically, from the Platonic original. Second, Gilead invokes distorted versions of ideas from philosophies other than Plato’s. I explore two ways of making sense of Gilead’s distorted philosophical appropriations. The explanations differ over whether such distortions (...) are best explained by the nature of the philosophies they misrepresent, or by the nature of Gilead. The explanation that emphasizes Gilead’s own agency is ultimately best able to make sense of how illiberal regimes misappropriate philosophical concepts, both in the novel and in reality, in order to limit the political imagination of their subjects.

Edward Feser defends the ‘Neo-Platonic proof ’ for the existence of the God of classical theism. After articulating the argument and a number of preliminaries, I first argue that premise three of Feser’s argument—the causal principle that every composite object requires a sustaining efficient cause to combine its parts—is both unjustified and dialectically ill-situated. I then argue that the Neo-Platonic proof fails to deliver the mindedness of the absolutely simple being and instead militates against its mindedness. Finally, I uncover two (...) tensions between Trinitarianism and the Neo-Platonic proof. (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 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 ..

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.

Reflections on the linkage between and the provocative force of problems in the analogy of city and soul, in the simile-bound characterization of the Good, and in the performative tension between what Plato has Socrates say about the philosopher's disinclination to descend into the city and what he has Socrates do in descending into the Piraeus to teach, with a closing recognition of the analogy between Socratic teaching and Platonic writing.

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)

Platon s'est inspir? des travaux philosophiques de certains de ses pr?d?cesseurs, en particulier Socrate, mais aussi Parm?nide, H?raclite et Pythagore, pour d?velopper sa propre philosophie, qui explore les domaines les plus importants, notamment la m?taphysique, l'?thique, l'esth?tique et la politique.

Some scientific explanations appear to turn on pure mathematical claims. The enhanced indispensability argument appeals to these ‘mathematical explanations’ in support of mathematical platonism.

Aristotle's syllogistic theory, as developed in his Prior Analytics, is often regarded as the birth of logic in Western philosophy. Over the past century, scholars have tried to identify important precursors to this theory. I argue that Platonic division, a method which aims to give accounts of essences of natural kinds by progressively narrowing down from a genus, influenced Aristotle's logical theory in a number of crucial respects. To see exactly how, I analyze the method of division as it was (...) originally conceived by Plato and received by Aristotle. I argue that, while Plato allowed that some divisions fail to rigorously investigate the essence, he began a program continued by Aristotle (and others in antiquity and the middle ages) of seeking norms for division that would apply in any domain whatsoever. This idea of a rigorous, general method was taken up and developed by Aristotle in his syllogistic. Aristotle also used Plato's conception of predication as parthood in his semantics for syllogistic propositions. As part of my argument, I prove that a semantics based on Platonic divisional structures is sound and complete for the deduction system used in the literature to model Aristotle's syllogistic.

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)

I argue that in the Phaedo, Plato maintains that the soul is located in space and is capable of locomotion and of interacting with the body through contact. Numerous interpreters have dismissed these claims as merely metaphorical, since they assume that as an incorporeal substance, the soul cannot possess spatial attributes. But careful examination of how Plato conceives of the body throughout his corpus reveals that he does not distinguish it from the soul in terms of spatiality. Furthermore, assigning spatial (...) attributes to the soul plays an important role in Plato’s account of the relation of body and soul. (shrink)

Plato's 'Symposium': Kierkegaard and Platonic Eros.

In this note I examine the two main differences between Plato's and Dennett's views of the self as an abstract object.

From the second half of the 16th century the question about Platonis Aristotelisque Concordia is no more a merely doctrinal problem, but it involves a discussion about methodus and ordo, according to the importance given to them in the coeval philosophical debate. In many cases underscoring Plato’s scientific merits, not only about inventio but also about the transmission of knowledge, meant promoting Platonism as a philosophy suitable for University. In this context the need for Platonic handbooks is perceived as compelling, (...) due to the recognised didactic superiority of Aristotle’s writings. The Compendio and the Vere Conclusioni are the specific contribution of Francesco Verino secondo, who gave holiday lectures on Plato at the Florentine Studium from 1576 to 1579.

In order to give light to Verino’s lectureship, particular attention is paid to glosses in his working and teaching copy of Platonis Opera. (shrink)

In the twenty-fourth aporia of Theophrastus' Metaphysics, there appears an important, if ‘bafflingly elliptical’, ascription to Plato and the ‘Pythagoreans’ of a theory of reduction to the first principles via ‘imitation’. Very little attention has been paid to the idea of Platonic and ‘Pythagorean’ reduction through the operation of ‘imitation’ as presented by Theophrastus in his Metaphysics. This article interrogates the concepts of ‘reduction’ and ‘imitation’ as described in the extant fragments of Theophrastus’ writings – with special attention to his (...) Metaphysics – in an attempt to make sense of how, precisely, Theophrastus characterizes the metaphysical systems of Plato and the ‘Pythagoreans’. A fuller examination of Aporia 24 produces important new understandings of the nature of the Early Academy in the mid fourth century B.C.E. Specifically, by ascribing the concept of reduction via ‘imitation’ to Plato and the ‘Pythagoreans’, Theophrastus is actually describing theories about the structure of the universe held by an important Platonist competitor and the contemporary head of the Academy in Athens, Xenocrates of Chalcedon (396/5–314/13 B.C.E.), who (a) took it upon himself to establish a Platonic doctrine that could be associated with his master’s writings and (b) coordinated that doctrine with the philosophical precepts of the Pythagoreans. As a consequence, we are prompted to question Aristotle’s famous ascription of a theory of ‘imitation’ to the metaphysics of the genuine contemporary or recently deceased Pythagoreans (such as Philolaus of Croton or Archytas of Tarentum) and consider how Xenocrates’ writings on Plato and the ‘Pythagoreans’ might be informing both Theophrastus’ and Aristotle’s descriptions of the Platonic and Pythagorean philosophical system(s).

Aristóteles comparte con Platón la concepción de la forma como causa del ser y del conocimiento de las cosas. Sin embargo, un análisis de sus críticas a las Ideas muestra que encuentra en la separación de las Ideas y las cosas sensibles la aporía fundamental de la teoría platónica. Con el propósito de circunscribir el significado de “separación” aplicable a las Ideas, concentraremos nuestro estudio en dos objeciones: 1) el argumento que conduce al tercer hombre y 2) la inutilidad de (...) las Ideas como causas. En el primer caso, creemos que la separación entraña homonimia, por lo que la solución aristotélica implicará la comunidad de naturaleza entre el individuo y su esencia. En el segundo, la separación implica trascendencia o falta de contacto entre generante y generado, por lo que la solución aristotélica apuntará a concebir la forma de las entidades naturales como un principio inmanente, inseparable de la materia y del movimiento, pero a la vez eterno a través de su reproducción en otros individuos de la misma especie. Creemos que en ambas soluciones opera un principio de sinonimia, que constituye su propia contribución al problema de la separación. (shrink)

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.

In Plato's Euthydemus, Socrates claims that the possession of epistēmē suffices for practical success. Several recent treatments suggest that we may make sense of this claim and render it plausible by drawing a distinction between so-called “outcome-success” and “internal-success” and supposing that epistēmē only guarantees internal-success. In this paper, I raise several objections to such treatments and suggest that the relevant cognitive state should be construed along less than purely intellectual lines: as a cognitive state constituted at least in part (...) by ability. I argue that we may better explain Socrates' claims that epistēmē suffices for successful action by attending to the nature of abilities, what it is that we attempt to do when acting, and what successful action amounts to in the relevant contexts. These considerations suggest that, contrary to several recent treatments, the success in question is not always internal-success. (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. Les formes sont des archétypes parfaits dont les objets réels sont des copies imparfaites. -/- DOI: 10.13140/RG.2.2.12629.70883. (shrink)

The usual interpretation of Republic 10 takes it as Socrates’ multilevel philosophical demonstration of the untruth and dangerousness of mimesis and its required excision from a well ordered polity. Such readings miss the play of the Platonic mimesis which has within it precisely ordered antistrophes which turn its oft remarked strophes perfectly around. First, this argument, famously concluding to the unreliability of image-makers for producing knowledge begins with two images—the mirror (596e) and the painter. I will show both undercut the (...) argument they introduce. Secondly, Socrates repeats the “three removes” argument three times. Each has its own object and philosophical axis. The “bed” argument (596a-598d) concerns the ontological status of images vis-à-vis human makers and the divine idea. The bit and bridle,” 601b-601d) emphasizes the epistemological status of image-making as beneath the human maker of bridles (having correct opinion) and the human user, who knows. This second takes away the ontological distinction which was the point of the first. Thus, any human being could be in any of the three positions—user, maker, imitator. This dance might bring one to doubt the conclusion that the imitator has “neither knowledge nor right opinion” (602a). Plato leads into his concluding psychological and moral argument (602c-605c) after a third variation of the 3 removes. This last gives us the image of the flute player (601d-602) as the one who knows and so can order the flute maker. We will conclude by considering what it is this flutist could know, and given that his art is itself a mimesis, who the imitator of this imitative artist could be. Thus attention to the differences among these examples opens a defense of the arts, which reverses many of the claims made against the arts within the ostensible “Platonic” argument. (shrink)

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)

A two-fold study, on the one hand of the thought-provoking mimesis by which Plato gives his hearer an occasion for self-knowledge and self-transcendence and of the typical sequential structure, an appropriation of the trajectory of the poem of Parmenides, by which Plato orders the drama of inquiry, and on the other hand a commentary on the Crito that aims to show concretely how these elements — mimesis and Parmenidean structure — work together to give the dialogues their exceptional elicitative power.

El conocimiento ha incursionado como tema de gran alcance dadas las múltiples disciplinas que lo evocan y cuyos intereses investigativos incurren en una definición para este. Primeras cavilaciones acerca del conocimiento se adelantaron bajo una óptica dualista de materialismo e idealismo, ambas posturas de carácter filosófico que determinaron el pensar de Occidente. Dicho así, desde la Grecia clásica pensadores como Platón, entre otros clásicos, entronizaron esta cuestión, pero dicho trato dualista en el ámbito del saber estuvo fuertemente vinculado con una (...) reflexión de talante ético del que Platón no se eximió. Con lo dicho, el presente artículo busca describir los postulados gnoseológicos y éticos en Platón con el fin de esclarecer el nexo entre conocimiento y práctica humana. (shrink)

In the whole Corpus Platonicum, we find in principle only one "direct argument" (Charles Kahn) for the existence of the ideas (Tim.51d3-51e6). The purpose of the article is to analyse this argument and to answer the question of why Plato in the Timaeus again defended the existence of the ideas despite the objections in the Parmenides. He defended it again because the latent presupposition of the apories in the Parmenides, the substantial view of sensibles, is removed through the introduction of (...) space as "substantialized extension". First (I) it is shown that Plato remained in dialogues, like the Sophist and Politicus, faithful to the "theory of ideas" despite his criticism in the Parmenides. The common theme in the trilogy of the Theaetetus, Sophist and Politicus is to refute relativism by showing that any relativism presupposes something absolute that is something like the "theory of ideas". The second part of the paper (II) examines closely the logical structure of the argument for the existence of ideas in the Timaeus (51d3-52a7). The third part (III) shows how this argument can avoid the criticism of ideas in the Parmenides. In the Parmenides, sensibles are treated as substantial entities. But, as the Timaeus shows, sensibles are not substantial entities but merely qualities, namely qualities of space, which is the only substance in the sensible world. A shortened English version of the paper appeared in Proceedings of the Fourth Symposium Platonicum, Granada, Selected papers, ed. by T. Calvo/L. Brisson, Academia Verlag, St. Augustin, 1997, 179-186. -/- But the only "direct argument" (Tim.51d3-51e6) seems to be interestingly flawed. Cf. Ferber, Rafael; Hiltbrunner, Thomas, (2005). (shrink)

Comentario de "La Republica " de Platon.

how does one inquire into the truth of first principles? Where does one begin when deciding where to begin? Aristotle recognizes a series of difficulties when it comes to understanding the starting points of a scientific or philosophical system, and contemporary scholars have encountered their own difficulties in understanding his response. I will argue that Aristotle was aware of a Platonic solution that can help us uncover his own attitude toward the problem.Aristotle's central problem with first principles arises from the (...) fact that they cannot be demonstrated in the same way as other propositions. Since demonstrations proceed from prior and better-known principles, if the principles themselves were in need of... (shrink)

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 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.

I argue that Plato distinguishes between personal immortality and immortality of the soul. I begin by criticizing the consensus view that Plato identifies the person and the soul. I then turn to the issue of immortality. By considering passages from 'Symposium' and 'Timaeus', I make the case that Plato thinks that while the soul is immortal by nature, if a person is going to be immortal, they must become so. Finally, I argue that Plato has a psychological continuity approach to (...) personal identity. Thus, for Plato, a person becomes immortal by avoiding reincarnation and securing for themselves psychological continuity forever. (shrink)
