This is a study of the correspondence between Forms and particulars in Plato. The aim is to determine whether they exhibit an ontological symmetry, in other words, whether there is always one where there is the other. This points to two questions, one on the existence of things that do not have corresponding Forms, the other on the existence of Forms that do not have corresponding things. Both questions have come up before. But the answers have not been sufficiently sensitive (...) to the intricacies of the questions. Nor have they been adequately resourceful with what little evidence there is in the original sources. The intention here is to make up for that deficiency, not just with better answers but also with better insight into the questions. (shrink)

Frente a quienes sostienen una incompatibilidad entre historia de la filosofía y filosofía, en cuanto plantean una disyuntiva entre una práctica descriptiva y una argumentativa, en este trabajo nos proponemos mostrar, examinando la labor histórico-filosófica de Aris- tóteles, que esa disyuntiva no es excluyente. Para ello, en primer lugar, examinaremos algunos pasajes de su obra en los que ofrece indicaciones metodológicas que permiten comprender la doble función que cumplen las exposiciones críticas de los filósofos precedentes en la constitución misma de (...) su filosofía. En segundo lugar, ilustraremos el tipo de argumentación aristotélica a través del análisis de las críticas que dirige a las Ideas platónicas como causas. Contra Platón, Aristóteles establece que, para dar cuenta de la ingenerabilidad e incorruptibilidad de las formas, no es necesario caracterizarlas como entidades separadas de la materia y del movimiento. Basta asegurar la eternidad de la forma a través de su reproducción en otros individuos de la misma especie. Tal análisis nos permite concluir, finalmente, que filosofía o historia de la filosofía constitu- yen una falsa disyuntiva en Aristóteles, por lo que el examen dialéctico de las doctrinas precedentes es un método adecuado de indagación filosófica.

It is a notion commonly acknowledged that in his work Timaeus the Athenian philosopher Plato (_c_. 429–347 BC) laid down an early chemical theory of the creation, structure and phenomena of the universe. There is much truth in this acknowledgement because Plato’s “chemistry” gives a description of the material world in mathematical terms, an approach that marks an outstanding advancement over cosmologic doctrines put forward by his predecessors, and which was very influential on western culture for many centuries. In the (...) present article, I discuss inter-transformations among Plato’s four types (fire, air, water, and earth) as well as the interpretation they received in the literature. I find that scientists and scholars generally emphasized (and often misunderstood) mathematical aspects of these “reactions” over the philosophical ones. I argue that Plato’s “chemistry” in fact bears on crucial topics of his philosophical system, such as Forms, Becoming, causation and teleology. I propose that consideration of these doctrines help to understand not only the sense of his “chemical” reactions, but also the reason why their stoichiometry is by surface balance and is restricted only to types that come to be and pass away but not to those that provoke the inter-transformations.

Interpretations of recollection in the "Phaedo" are divided between ordinary interpretations, on which recollection explains a kind of learning accomplished by all, and sophisticated interpretations, which restrict recollection to philosophers. A sophisticated interpretation is supported by the prominence of philosophical understanding and reflection in the argument. Recollection is supposed to explain the advanced understanding displayed by Socrates and Simmias (74b2-4). Furthermore, it seems to be a necessary condition on recollection that one who recollects also perform a comparison of sensible particulars (...) to Forms (74a5-7). I provide a new ordinary interpretation which explains these features of the argument. First, we must clearly distinguish the philosophical reflection which constitutes the argument for the Theory of Recollection from the ordinary learning which is its subject. The comparison of sensibles to Forms is the reasoning by which we see, as philosophers, that we must recollect. At the same time, we must also appreciate the continuity of ordinary and philosophical learning. Plato wants to explain the capacity for ordinary discourse, but with an eye to its role as the origin of philosophical reflection and learning. In the "Phaedo", recollection has ordinary learning as its immediate explanandum, and philosophical learning as its ultimate explanandum. (shrink)

Corrective intervention in Plato's metaphysics replacing the standard view of Plato as a metaphysical dualist with a novel and revolutionary paradigm of unitary pluralism in a single reality built on ontological diversity.

In this paper I present an original interpretation of the concept of separation in Plato. First, I argue that despite the fact that the ancient Greek word for “separation” almost never appears in the metaphysical discussions of Plato’s dialogues, the key role of the concept of separation in Plato’s metaphysics can be attested by the importance the platonic tradition gives to it. Therefore, understanding separation in Plato seems to be a problem we must face, but we do not have a (...) clear strategy to solve it. My strategy will be to tackle this problem by looking at a specific passage in which Plato distinguishes the ontological status of Forms and sensible things. Through the analysis of this passage and its relations to another metaphysical argument in Plato, I hope to show that Plato’s careful choice of words and syntactical structure of sentences aims to distinguish two ontologically different types of entities: the unrelational, separate Forms, and the relational sensible things.

The doctrine of the conceptual priority of the perfect (CPP) is the claim that the concept of the perfect is prior to that of the imperfect insofar as possessing the latter presupposes a grasp of the former, but not vice versa. The goals of this study are to provide an account and defense of the Cartesian argument for CPP, to determine the consequences of this priority for the relationship between our concepts of human and divine properties, and to explore its (...) implications for bottom-up accounts of theological concept formation. I argue that the predicates “perfect” or “infinite” in Descartes’ version of CPP are equivalent to “true” or “genuine” and thus function in the same way they would in geometrical examples where the perfection at issue is definitive of the kind and where imperfection constitutes falling short of the kind. I can thus be said to have the idea of a “perfect” circle (of that which is “infinitely” circular, as it were) merely by virtue of having the idea of a circle, yet I cannot apprehend something as imperfect or finite insofar as it resembles but fails to be a circle unless I already possess a concept of the kind in question—a true or perfect circle. CPP thus implies a qualitative distinction between the perfect and imperfect that, when applied to God and creation, is consistent with a theory of analogy. Unlike traditional ‘bottom-up’ theories of analogy, however, CPP entails a ‘top-down’ order of derivation in which concepts of creaturely perfections are derived (via a sort of ‘partial negation’) from concepts of divine ones. The ‘top-down’ order of derivation yields epistemological advantages over the traditional approach, which had always struggled to explain how we can derive analogical concepts of God from creatures. Further, CPP enables its proponents to address the classic anthropomorphism critiques leveled at practitioners of Perfect Being Theology. Though I acknowledge that CPP is not without its own weaknesses, I present a largely sympathetic account of the argument and its relevance for contemporary philosophy of religion. (shrink)

In Republic V, Plato distinguishes two different cognitive powers, knowledge and belief, which operate differently on different types of object. I argue that in Republic VI Plato modifies this account, and claims that there is a single cognitive power, which under different circumstances behaves either as knowledge or as belief. I show that the circumstances which turn true belief into knowledge are the provision of an individuation account of the object of belief, which reveals the ontological status and the nature (...) of the object. Plato explores many alternative candidates of individuation accounts of objects of true belief, which he discards. I conclude with a Platonic sketch of a teleological account of individuation which would satisfy his requirements of turning true belief into knowledge. (shrink)

In the so-called “erotic dialogues”, especially the Symposium and the Phaedrus, Plato explained why erotic desire can play an epistemic function, establishing a strong connection between erotic desire and beauty, “the most clearly visible and the most loved” among the Ideas. Taking the erotic dialogues as a background, in this paper I elucidate Plato’s explanation in another context, the one of the Phaedo, for discussing the epistemic function of erotic desire in relation to the deficiency argument and the affinity argument. (...) My claim is that the erotic desire of the philosopher is activated by the recognition of traces of the Ideas as something that the material world lacks and that, nevertheless, his soul is familiar with. This desire for the Ideas triggers the process of recollection, and thus erotic desire acquires a decisive role in the acquisition of knowledge in the Phaedo. In the final section of the paper, I highlight the contemporary relevance of Plato’s epistemology of erotic desire. (shrink)

The argument at Phaedo 74 B 4‐C 6 that the equal itself is ‘something different from’ sets of physical equals depends on Leibniz's Law: there is a property that perceptible equals have that the equal itself does not have. What I call the ‘epistemic interpretation’ holds that the property is an epistemic one: having appeared unequal. The ‘ontological interpretation’ holds that the property is not epistemic, but simply the property of being unequal. The most natural reading of the text favours (...) the epistemic interpretation; scholarly support for the ontological interpretation is based on the widely held view that on the epistemic interpretation the argument is manifestly invalid. But this view implicitly relies on an impoverished sense of ‘appearing’ as equivalent to ‘being thought’. Drawing on an analogy with colour perception, I elaborate an experiential sense of ‘appearing’ which makes Plato's argument on the epistemic interpretation philosophically defensible. (shrink)
