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.

_ Source: _Volume 61, Issue 1, pp 60 - 81 This paper presents an analysis of some passages of Alcinous, _Didaskalikos_ 4. Its aim is to show, on the one hand, that Alcinous suggests a reading of the main points of Plato’s epistemology focused on a hard dualistic interpretation of both the theory of forms and recollection; and, on the other hand, that in the text there is no real acceptance of Stoic doctrines, but only an attempt to show that (...) outside of the Platonic framework no suitable account for Stoic notions such as _logos_ or _physikai ennoiai_ can be provided.

This article examines the theory of recollection in Plato's Meno and attempts to unravel some long-standing puzzles about it. What are the prenatal objects of the soul's vision? What are the post-natal objects of the soul's recollection? What is innate in the Meno? Why does Socrates (prima facie) suggest that both knowledge and true opinion are innate? The article pays particular attention to the ana- prefix in the verbs aneuriskô, anakineô and analambanô, and suggests that they are used for two (...) distinct stages of recollection: a phenomenological stage of ‘finding again’ or ‘awakening’ our innate content, which Plato calls doxa, and an epistemic stage of ‘getting it back’ as epistêmê. Thinking of the verbs with this ‘back/again’ sense of the ana- prefix (instead of as ‘up’, in the common translation of analambanô as ‘take up’) allows us to understand why Plato would simultaneously imply that our souls had prenatal epistêmê, have post-natal innate true opinion and have the potential to analambanein epistêmê. He is not talking about ‘taking up’ epistêmê that he also calls doxa, but about ‘getting back’ the epistêmê we had prenatally. The article concludes with an examination of what this innate content is, suggesting that it is a type of ‘principle’ and ‘essential’ mental content. (shrink)

In this paper I focus on Proclus’ concept of the instrumental cause in his commentary on the Timaeus (In Tim.). Unlike earlier Neoplatonists who do not make much use of this type of causality, Proclus relates the instrumental cause to the hypostasis of nature (φύσις). The Demiurge uses nature as an instrument in his ordering and creation of the cosmos. How does Proclus arrive at this understanding of nature? I argue that the definition of nature as an instrumental cause is (...) in part based on his critical reception of Aristotle who identifies nature with the formal, efficient, and/or final cause. That is, Proclus did not develop his views on the causality of nature only by looking at the Timaeus (and other Platonic sources), but also by engaging with Aristotle’s rich – and, to a certain extent, authoritative – reflections on this issue.

In hisCommentary on the AlcibiadesiProclus often discusses and links the peculiar epistemological category of “double ignorance” with evil and grievous error. To understand this more fully, the following analyzes Proclus’ concept of double ignorance, its characteristics and its causes. Markedly, due to his understanding of double ignorance, Proclus offers a response to the “Socratic” idea that no one willingly errs as this particular category of not-knowing enables him to explain how individuals, despite desiring and in some sense knowing the good, (...) fail or ‘miss the mark’ in articulating and doing the good.

Philosophers have long been interested in the study of induction. This paper aims at examining Philoponus’ treatment, with a focus on his commentary on the Posterior Analytics, which is an especially rich source of information on this topic. Following in Aristotle’s footsteps, Philoponus maintains that it is through induction that universal knowledge is achieved, but in his interpretation of the Aristotelian doctrine he also introduces intriguing novelties. In particular, I argue that in some passages he treats induction as an intellectual (...) means of teaching and learning, that is, as a logical argument-form in which a universal conclusion is inferred from particular premises. In other passages, however, he treats induction as a sort of sense perception, specifically that which triggers the recovery of innate universal knowledge. (shrink)

Kind representations, concepts like table, triangle, dog, and planet, underlie generic language. Here, we investigate the formal structure of kind representations—the structure that distinguishes kind representations from other types of representations. The present studies confirm that participants distinguish generic‐supporting properties of individuals (e.g., this watch is made of steel) and accidental properties (e.g., this watch is on the nightstand). Furthermore, work dating back to Aristotle establishes that only some generic‐supporting properties bear a principled connection to the kind, that is, are (...) true of an individual by virtue of its being a member of a specific kind (e.g., telling time for a watch). The present studies tested the hypothesis that principled connections are part of the formal structure of kind representations. Specifically, they tested whether they structure a newly learned kind representation. Experiment 1 found that introducing a property of a newly encountered novel kind in any one of four linguistic frames that provide evidence that a property has a principled connection to a kind (e.g., “It has fur because it is a blick”) led participants to infer a different conceptual consequence of principled connections (i.e., “There is something wrong with this blick, which does not have fur”) for which they had no direct evidence. Two introduction frames that provided no evidence for principled connections (e.g., “Almost all blicks have fur”) did not generate the same consequence. Experiment 2 found that all of the targeted properties were generic licensing, irrespective of the introduction frame. That the distinction between properties that bear principled connections to their kinds, and merely generic‐supporting properties structures novel kind representations, provides strong evidence that this distinction is part of the formal structure of kind representations.

In his own De anima, Alexander of Aphrodisias famously identifies the “active” (poietikon) intellect with the prime mover in Metaphysics Λ. However, Alexander’s claim raises an issue: why would this divine intellect come in the middle of a study of soul in general and of human intellection in particular? As Paul Moraux asks in his pioneering work on Alexander’s conception of the intellect, is the active intellect a “useless addition”? In this paper, I try to answer this question by challenging (...) a solution according to which the active intellect would intervene directly with the material intellect to trigger its ordinary working. I argue that the active intellect acts as a final cause, both for human intellect and for its ordinary objects of thought. The active intellect is twice “cause of the intellection”, i.e. cause of the actualization of human thought: once (i) when it offers thought occasions for thinking through objects, and again (ii) when it actualizes mediately the human intellect itself in its development. This reading agrees with Alexander’s usual position about the prime mover’s causality. It accounts for the multiplicity of expressions with which Alexander describes the causality of the active intellect in his De anima. It also explains why the development of human intellect has been described without direct reference to active intellect, since substances do not aim directly at the First cause, but their aiming at it is mediated by their desire for their own good.

At Aristotle,MetaphysicsE.1, 1026a14, Schwegler’s conjectural emendation of the manuscript reading ἀχώριστα to χωριστά has been widely adopted. The objects of physical science are therefore here ‘separate’, or ‘independently existent’. By contrast, the manuscripts make them ‘not separate’, construed by earlier commentators as dependent on matter. In this paper, I offer a new defense of the manuscript reading. I review past defenses based on the internal consistency of the chapter, explore where they have left supporters of the emendation unpersuaded, and attempt (...) to strengthen their appeal. I challenge Schwegler’s central case, developed by Ross and others, that the construction μὲν ἀλλ’ οὐκ demands an implausible ‘logical antithesis’ between inseparability and mobility. This is arguably the fundamental obstacle to the manuscript reading, and counterexamples have not to date convinced emenders. I offer a new, systematic review of Aristotle’s use of the phrase, including relevant cases from theRhetoric, to show how its usual meaning in Aristotle supports the transmitted text; I also reply to possible objections. Finally, I explore the implications of this defense for the classification of the sciences in E.1. (shrink)

This paper discusses the role of innate concepts derived from Intellect in Plotinus’ account of cognition of the sensible realm. Several passages have been claimed as evidence for such innateness, but an analysis of them shows that they do not support this claim. It is tentatively suggested that, nevertheless, some very general concepts such as difference, sameness and being are integral to the faculty of sense and play a crucial role in concept formation. It is further argued that reasoning about (...) the sensible realm takes place to a large extent without the involvement of the higher realms of Plotinus’ hierarchy of being. Clearly, however, for value concepts such as those of goodness, justice and beauty human beings are dependent upon an illumination from Intellect. (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.
