In Philosophy and the Mirror of Nature (1979), Richard Rorty locates the perceived ills of modern philosophy in the "epistemological turn" of Descartes and Locke. This chapter argues that Rorty's accounts of Descartes' and Locke's philosophical work are seriously flawed. Rorty misunderstood the participation of early modern philosophers in the rise of modern science, and he misdescribed their examination of cognition as psychological rather than epistemological. His diagnostic efforts were thereby undermined, and he missed Descartes' original conception of a general (...) physics, and Locke's probabilist analysis of the grounds for rational belief. (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)

According to naïve realist (or primitivist) theories of colour, colours are sui generis mind-independent properties. The question that I consider in this paper is the relationship of naïve realism to what Mark Johnston calls Revelation, the thesis that the essential nature of colour is fully revealed in a standard visual experience. In the first part of the paper, I argue that if naïve realism is true, then Revelation is false. In the second part of the paper, I defend naïve realism (...) against a number of objections.

The emperor's new mind (hereafter Emperor) is an attempt to put forward a scientific alternative to the viewpoint of according to which mental activity is merely the acting out of some algorithmic procedure. John Searle and other thinkers have likewise argued that mere calculation does not, of itself, evoke conscious mental attributes, such as understanding or intentionality, but they are still prepared to accept the action the brain, like that of any other physical object, could in principle be simulated by (...) a computer. In Emperor I go further than this and suggest that the outward manifestations ofconscious mental activity cannot even be properly simulated by calculation. To support this view, I use various arguments to show that the results of mathematical insight, in particular, do not seem to be obtained algorithmically. The main thrust ofthis work, however, is to present an overview ofthe present state of physical understanding and to show that an important gap exists at the point where, quantum and classical physics meet, as well as to speculate on how the conscious brain might be taking advantage ofwhatever new physics is needed to fill this gap to achieve its nonalgorithmic effects.

This paper considers the alleged pragmatism of Berkeley’s philosophy using the two Sellarsian categories of ‘manifest’ and ‘scientific’ images of the world and human beings. The ‘manifest’ image is regarded as a refinement of the ordinary way of conceiving things, and the scientific image is seen as a theoretical picture of the world provided by science. The paper argues that the so-called Berkeleian pragmatism was an effect of Berkeley’s work towards a synthesis of ‘manifest’ and ‘scientific’ images through the creation (...) of one unified synoptic vision of the world and was a part of a new conceptual framework within which these two images could be combined.

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)

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)

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.

The primary aim of this paper is to provide a new account of Descartes’s positive philosophical view on sensory perception, and to do so in a way that will establish a hitherto unnoticed continuity between his thought and that of his scholastic Aristotelian predecessors on the topic of sensory perception. I will argue that the basic framework of the scholastic Aristotelian view on sensory perception (as traditionally understood) is operative within Descartes's own view, and then reveal some insights on the (...) issue of whether Descartes was a representationalist about sensory perception by critically examining one kind of representationalist reading of Descartes under the lens of my account. I will conclude by examining the implications that my view has for the proposed distinction between Descartes and the scholastics based on attributing representationalism to the former and direct-realism to the latter.
