Most theories of concepts take concepts to be structured bodies of information used in categorization and inference. This paper argues for a version of atomism, on which concepts are unstructured symbols. However, traditional Fodorian atomism is falsified by polysemy and fails to provide an account of how concepts figure in cognition. This paper argues that concepts are generative pointers, that is, unstructured symbols that point to memory locations where cognitively useful bodies of information are stored and can be deployed to (...) resolve polysemy. The notion of generative pointers allows for unresolved ambiguity in thought and provides a basis for conceptual engineering. (shrink)

Berkeley’s likeness principle is the claim that “an idea can be like nothing but an idea”. The likeness principle is intended to undermine representationalism: the view (that Berkeley attributes to thinkers like Descartes and Locke) that all human knowledge is mediated by ideas in the mind which represent material objects. Yet, Berkeley appears to leave the likeness principle unargued for. This has led to several attempts to explain why Berkeley accepts it. In contrast to ‘metaphysical’ and ‘epistemological’ interpretations available in (...) the literature, in this paper I defend a ‘conceptual’ interpretation. I argue that Berkeley accepts the likeness principle on the basis of (i) his commitment to the transparency of ideas, and (ii) his account of resemblance which he sets out in his works on vision. Thus, I provide an explanation for Berkeley’s reasons for accepting the likeness principle which, appropriately, focuses on his views concerning ideas and likeness. (shrink)

It is a characteristic feature of our mental make-up that the same perceptual input situation can simultaneously elicit conflicting mental perspectives. This ability pervades our perceptual and cognitive domains. Striking examples are the dual character of pictures in picture perception, pretend play, or the ability to employ metaphors and allegories. I argue that traditional approaches, beyond being inadequate on principle grounds, are theoretically ill equipped to deal with these achievements. I then outline a theoretical perspective that has emerged from a (...) theoretical convergence of perceptual psychology, ethology, linguistics, and developmental research. On the basis of this framework, I argue that corresponding achievements are brought forth by a specific type of functional architecture whose core features are as follows: (1) a perceptual system that is biologically furnished with a rich system of conceptual forms, (2) a triggering relation between the sensory input and conceptual forms by which the same sensory input can be exploited by different types or systems of conceptual forms, and (3) computational principles for handling semantically underspecified conceptual forms. Characteristic features of the proposed theoretical framework are pointed out using the Heider–Simmel phenomenon as an example. (shrink)

Ideas about soul and body – about thinking or remembering, mind and life, brain and self – remain both diverse and controversial in our neurocentric age. The history of these ideas is significant both in its own right and to aid our understanding of the complex sources and nature of our concepts of mind, cognition, and psychology, which are all terms with puzzling, difficult histories. These topics are not the domain of specialists alone, and studies of emotion, perception, or reasoning (...) have never been isolated theoretical endeavours. As Francis Bacon described human philosophy or ‘the knowledge of ourselves’, within which he located the study of body, soul, and mind, it ‘deserveth the more accurate handling, by how much it toucheth us more nearly’ (1605/ 2000: 93). The history of ideas in these domains is particularly challenging given the practical dimensions and implications of theories of mind. Because theories of human nature and debates about body and mind do ‘touch us’ so ‘nearly’, they attract and can thus reveal, in specific historical contexts, interconnected discourses or associations which may be quite unlike our own. So there are no neat boundaries around a historical category of ‘seventeenth-century British philosophy of the soul’. The central topic of this chapter can be thought of either as pneumatology, the doctrine or science of spirits and souls, or as continuous with the ‘psychologia’ or psychology of Aristotelian traditions (Park and Kessler 1988; Hatfield 1995: 184-6). In neither case, however, should we expect any deep unity to be provided by history, geography, discipline, or subject-matter. (shrink)

Locke’s theory of consciousness is often appropriated as a forerunner of present-day Higher-Order Perception (HOP) theories, but not much is said about it beyond that. We offer an interpretation of Locke’s account of consciousness that portrays it as crucially different from current-day HOP theory, both in detail and in spirit. In this paper, it is argued that there are good historical and philosophical reasons to attribute to Locke the view not that conscious states are accompanied by higher-order perceptions, but rather (...) that conscious states constitute perceptions of themselves.

The chapter argues from an ethology-inspired internalist perspective that ‘colour’ is not a homogeneous and autonomous attribute, but rather plays different roles in different conceptual forms underlying perception. It discusses empirical and theoretical evidence that indicates that core assumptions underlying orthodox conceptions are grossly inadequate. The assumptions pertain to the idea that colour is a kind of autonomous and unitary attribute. It is regarded as unitary or homogeneous by assuming that its core properties do not depend on the type of (...) ‘perceptual object’ to which it pertains and that‘colour per se’ constitutes a natural attribute in the functional architecture of the perceptual system. It is regarded as autonomous by assuming that it can be studied in isolation of other perceptual attributes. More generally, the chapter argues on the bases of corresponding empirical and theoretical evidence that perception cannot be understood as the ‘recovery’ of physical world structure from sensory structure by input-based computational processes. Rather, the sensory input serves as a kind of sign for biologically relevant aspects of the external world that activates biologically given conceptual forms with their internal parameters. Although the sensory input is a causally necessary requirement for the activation of conceptual forms, the perceptual computations triggered are under the control of an internal programme based on a set of conceptual forms.

Descartes holds that ideas have or contain _objective reality_ of their objects, so that the idea of the sun is the sun itself existing in the intellect. In this paper, I examine this obscure thesis which grounds the disagreement about Descartes’ commitment to direct or indirect realism. I suggest that, importantly, both readings are correct to a certain extent. I argue that the view of objective reality Descartes develops bears the earmarks of both direct and indirect realist views but must (...) be classified as a third alternative combining some central features of both. I elaborate first on the direct realist interpretations of Descartes’ objective reality and explain their most significant shortcomings. My interpretation of objective identity comes in the form of attributing to Descartes a view about identity and persistence of objects known as _sortalism_. I argue that Descartes’ objective identity turns out to be much like the Aristotelian view of _formal identity_, yet without the forms. By way of discussing the case of Theseus’ ship, I point out how Cartesian sortalism, contrary to other versions of sortalism, allows us to analyze the puzzle as a tension between two distinct yet independently legitimate criteria of identity. It is this sortalist insight that helps to render Descartes’ account of objective identity consistent. This point also grounds my argument that we need not consider direct and indirect realism as logical complements, contrary to the received wisdom. (shrink)

The paper advances the hypothesis that, in Thomas Reid's reading, David Hume's skepticism of the Treatise on Human Nature is not solely due to his acceptance of the ‘ideal hypothesis’ – the principle according to which ideas are the immediate objects of the mental operations –, but it has another source, namely, that doubt on the reliability of the faculties of the senses, memory, and reason. Moreover, the paper argues that the suggested distinction between two roots for Hume’s skepticism allows (...) a more exact view on Reid’s reading of Hume and solve some misinterpretations. (shrink)

Mikä tarkalleen ottaen on aistimusten rooli ulkoisten objektien havaitsemisessa Descartesin mukaan? Descartes esittää, ettei ulkoisia olioita havaita aistien avulla, vaan pelkästään mielen tarkastelulla. Yksi tapa ymmärtää Descartesin väite on ajatella, että suhde havaitsijan ja objektin välillä edellyttää päättelyä aistimuksista itse olion läsnäoloon. Toinen mahdollisuus on ajatella, että itse asiassa aistimukset ovat suhteellisen yhdentekeviä havainto-relaatiolle, ja että tämä relaatio muodostuu tietyllä tapaa syvemmän maailman rakenteen ymmärtämisestä. Tässäkin näkemyksessä aistimuksilla on tietty rooli, mutta kyse ei ole päättelystä aistimuksista objektin läsnäoloon, kuten edellisessä (...) näkemyksessä, vaan päättelykyvyn käyttäminen kohdistuu pikemmin ajattelijan ja objektin välisten suhteiden ymmärtämiseen laajemman metafyysisen viitekehyksen avulla. Tämä kirjoitus tarkastelee tätä jälkimmäistä vaihtoehtoa mahdollisena tulkintana Descartesin havaintokäsityksessä ja pohtii samalla erityisesti aistimusten toimintoa havainnossa. (shrink)

This article closely compares the opposing foundations of theoretical philosophy in René Descartes and Ayn Rand. The developmental course of Rand's foundations, with their continual opposition to Descartes, is tracked. Arguments particularly against Descartes are assembled in this article, and the bountiful contemporary scholarship on Descartes is engaged.

Generalmente los comentadores han abordado la temática de la intuición en la filosofía de Spinoza desde la perspectiva de la problemática de lo que en la Ética aparece como ciencia intuitiva o tercer genero de conocimiento. En el presente artículo, en cambio, intentamos mostrar que hay en los escritos de Spinoza un concepto de intuición más amplio que el que está implícito en la ciencia intuitiva, del cual esta no sería más que una subespecie. Como paso previo para alcanzar dicho (...) fin, intentaremos mostrar que la concepción de la intuición que sostiene Spinoza está estrechamente emparentada con la concepción cartesiana -de la cual ofrecemos un breve esbozo en el primer apartado- y que ambas concepciones tienen como fundamento la naturaleza de la idea. Generally, critics had tackle the issue of intuition in Spinoza’s philosophy from the point of view of the problem of what in the Ethics is called intuitive science or third kind of knowledge. In the present paper, instead, we try to show that there is in Spinoza`s writings a wider concept of intuition than that which is implied in the intuitive science, being the later no more than a sub-kind of the former. As a previous step to achieve this target, we try to show that Spinoza`s conception of intuition is narrowly tied with the Cartesian conception -of which we offer a brief draft in the first part- and that both conceptions are based on the nature of the idea.

The Logic or the Art of Thinking, also called Port-Royal Logic, is an exemplar of modern reformers in logic and epistemology. Its reformism has a marked influence of Descartes, who introduces the epistemic and logical subject into the ground of justification of knowledge and judgment. A look at the method’s commitments in this text may shed light on the dynamics of the interweaving between epistemology and logic. It is in this perspective that an analysis of the use of the Aristotelian (...) notion of “techné”, as an “art of doing anything well” seems to require attention, since it happens in a logical domain, as the authors make it. In this paper I want to make clear that the mental actions are crucial to a logic as reflexive practice. And, because of that, the very expression of “art of thinking” shows itself as non-trivial, that is, as a requirement of method. (shrink)

Call the idea that states of perceptual awareness have intentional content, and in virtue of that aim at or represent ways the world might be, the ‘Content View.’ I argue that though Kant is widely interpreted as endorsing the Content View there are significant problems for any such interpretation. I further argue that given the problems associated with attributing the Content View to Kant, interpreters should instead consider him as endorsing a form of acquaintance theory. Though perceptual acquaintance is controversial (...) in itself and in attribution to Kant, it promises to make sense of central claims within his critical philosophy. (shrink)

What is early modern philosophy? Two interpretative trends have predominated in the related literature. One, with roots in the work of Hegel and Heidegger, sees early modern thinking either as the outcome of a process of gradual rationalization (leading to the principle of sufficient reason, and to "ontology" as distinct from metaphysics), or as a reflection of an inherent subjectivity or representational semantics. The other sees it as reformulations of medieval versions of substance and cause, suggested by, or leading to, (...) early modern scientific developments. -/- This book proposes a rather different kind of explanation. It suggests that the concept of relation, specifically that of dyadic, anti-symmetrical relations, can throw light on a wide variety of developments in early modern thought, such as those concerning causality, sense perception, temporality, and the mereological approach to substance. The book argues that these relations are grounded in an interpretation of causal influence, and not in semantic theories or subjectivity. -/- Furthermore, if it is correct that the problem of unity was, for most of classical antiquity, what the problems of motion, causality and perception were for early modern thinkers, then early modern thought is much closer to the thought of Aristotle than is commonly supposed. The genesis of early modern thought might instead be taken to have occurred in opposition to one aspect of the thought of Duns Scotus (an aspect that lives on in contemporary Neo-Aristotelianism), and that can be explained once the relational perspective examined here is taken into account.

George Berkeley, Bishop of Cloyne, was one of the great philosophers of the early modern period. He was a brilliant critic of his predecessors, particularly Descartes, Malebranche, and Locke. He was a talented metaphysician famous for defending idealism, that is, the view that reality consists exclusively of minds and their ideas. Berkeley's system, while it strikes many as counter intuitive, is strong and flexible enough to counter most objections. His most studied works, the Treatise Concerning the Principles of Human Knowledge (...) Principles, for short) and Three Dialogues between Hylas and Philonous Dialogues), are beautifully written and dense with the sort of arguments that delight contemporary philosophers. He was also a wide ranging thinker with interests in religion (which were fundamental to his philosophical motivations), the psychology of vision, mathematics, physics, morals, economics, and medicine. Although many of Berkeley's first readers greeted him with incomprehension, he influenced both Hume and Kant, and is much read (if little followed) in our own day. (shrink)

Robert Cummins [(1996) Representations, targets and attitudes, Cambridge, MA: Bradford/MIT, p. 1] has characterized the vexed problem of mental representation as "the topic in the philosophy of mind for some time now." This remark is something of an understatement. The same topic was central to the famous controversy between Nicolas Malebranche and Antoine Arnauld in the 17th century and remained central to the entire philosophical tradition of "ideas" in the writings of Locke, Berkeley, Hume, Reid and Kant. However, the scholarly, (...) exegetical literature has almost no overlap with that of contemporary cognitive science. I show that the recurrence of certain deep perplexities about the mind is a systematic and pervasive pattern arising not only throughout history, but also in a number of independent domains today such as debates over visual imagery, symbolic systems and others. Such historical and contemporary convergences suggest that the fundamental issues cannot arise essentially from the theoretical guise they take in any particular case. (shrink)

In 1765, Joseph Priestley created what may be the world's first modern timeline, A Chart of Biography. This paper offers the first study of the philosophy underlying Priestley's timeline. It argues that Priestley was pushed towards representing times as lines by his views on abstract ideas and time, and there is no reason to believe that Newtonian absolutism grounds his uniform depiction of time. Further, the Chart confirms, and even advances, Priestley's views on human progress. Finally, this study shows that (...) Priestley's conception of time as a line comprises a landmark contribution to the history of space-time parallelism. (shrink)

Malebranche argues that ideas are representative beings existing in God. He defends this thesis by an inference to the best explanation of human perception. It is well known that Malebranche’s theory of vision in God was forcefully rejected by philosophers such as Arnauld, Locke, and Berkeley. However, the notion that ideas exist in God was not the only controversial aspect of Malebranche’s approach. Another controversy centered around Malebranche’s view that ideas are to be understood as posits in an explanatory theory. (...) Opponents of this approach, including Arnauld and Locke, held that our talk about ideas was not explanatory but instead merely descriptive: we use the word ‘idea’ to describe phenomena that we observe by reflecting on our own minds. This controversy has not received much attention from scholars, but in the present paper I will show that it was an explicit and important subject of concern for Malebranche, Arnauld, Locke, and Berkeley and that attention to this controversy can illuminate several aspects of these philosophers’ work.
