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)

It is generally assumed that Descartes invokes “objective being in the intellect” in order to explain or describe an idea’s status as being “of something.” I argue that this assumption is mistaken. As emerges in his discussion of “materially false ideas” in the Fourth Replies, Descartes recognizes two senses of ‘idea of’. One, a theoretical sense, is itself introduced in terms of objective being. Hence Descartes can’t be introducing objective being to explain or describe “ofness” understood in this sense. Descartes (...) also appeals to a pretheoretical sense of ‘idea of’. I will argue that the notion of objective being can’t serve to explain or describe this “ofness” either. I conclude by proposing an alternative explanation of the role of objective being, according to which Descartes introduces this notion to explain the mind’s ability to attain clear and distinct ideas.

Intentionality (‘directedness’, ‘aboutness’) is both a central topic in contemporary philosophy of mind, phenomenology and the cognitive sciences, and one of the themes with which both analytic and Continental philosophers have separately engaged starting from Brentano and Edmund Husserl’s ground-breaking Logical Investigations (1901) through Roderick M. Chisholm, Daniel C. Dennett’s The Intentional Stance, John Searle’s Intentionality, to the recent work of Tim Crane, Robert Brandom, Shaun Gallagher and Dan Zahavi, among many others. In this paper, I shall review recent discussions (...) of intentionality, including some recent explorations of the history of the concept (paying particular attention to Anselm), and suggest some ways the phenomenological approach of Husserl and Heidegger can still offer insights for contemporary philosophy of mind and consciousness.

'If a person can think of an F, then that person has come into causal contact with an F in the right way' is a premise in an obvious reconstruction of Putnam's argument that we are not brains in vats. 'If a person can think of an F, then that person has come into causal contact with an F or with something at least as good as an F' is the only controversial premise in Descartes' argument for the existence of (...) God. Putnam's principle entails Descartes', which suggests that we should enquire after better versions of Putnam's proof. I present three variations and conclude that Putnam's semantic theory does not have anti-sceptical consequences. In contrast, given Descartes' cognitive situation, he was perfectly justified in accepting the soundness of his argument for the existence of God. (shrink)

At the heart of Descartes’s theory of cognition is the act of perceiving an idea. However, it remains unclear what precisely an idea is, what the act of perceiving ideas amounts to, and how that act contributes to the formation of cognition under Descartes’s view. In this paper, I provide an account of perceiving ideas that clarifies Descartes’s notion of an idea and explains the fundamental role that the perceiving of ideas occupies in his theory of cognition. At the end (...) of the paper, I will address an issue that arises regarding the objective reality of ideas and the unity of mind. (shrink)

Commentators standardly ascribe to Spinoza a belief in an exceptionless conceptual closure of mental and physical realms: no intention can allow us to understand a bodily movement, no bodily injury can make intelligible a sensation of pain. This counterintuitive doctrine, most often now referred to as Spinoza's 'attribute barrier', has weighty repercussions for his views on intelligibility, nature of the mind, identity, and causality. I argue against the standard reading of the doctrine, by showing that it produces an inconsistent epistemological (...) picture, contradicting Spinoza's theory of mind and his commitment to universal intelligibility. The alternative account I propose is also philosophically more compelling and plausible as an account of thought in its essential intentionality. (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)
