It is often argued that higher-level special-science properties cannot be causally efficacious since the lower-level physical properties on which they supervene are doing all the causal work. This claim is usually derived from an exclusion principle stating that if a higher-level property F supervenes on a physical property F* that is causally sufficient for a property G, then F cannot cause G. We employ an account of causation as difference-making to show that the truth or falsity of this principle is (...) a contingent matter and derive necessary and sufficient conditions under which a version of it holds. We argue that one important instance of the principle, far from undermining non-reductive physicalism, actually supports the causal autonomy of certain higher-level properties. (shrink)

Pettit (2006) argues that deferring to majority testimony is not generally rational: it may lead to inconsistent beliefs. He suggests that “another ... approach will do better”: deferring to supermajority testimony. But this approach may also lead to inconsistencies. In this paper, I describe conditions under which deference to supermajority testimony ensures consistency, and conditions under which it does not. I also introduce the concept of “consistency of degree k”, which is weaker than full consistency by ruling out only “blatant” (...) inconsistencies in an agent’s beliefs while permitting less blatant ones, and show that, while super-majoritarian deference often fails to ensure full consistency, it is a route to consistency in this weaker sense.

John Locke accepts that every perception gives me immediate and intuitive knowledge of my own existence. However, this knowledge is limited to the present moment when I have the perception. If I want to understand the necessary and sufficient conditions of my continued existence over time, Locke argues that it is important to clarify what ‘I’ refers to. While we often do not distinguish the concept of a person from that of a human being in ordinary language, Locke emphasizes that (...) this distinction is important if we want to engage with questions of identity over time. According to Locke, persons are thinking intelligent beings who can consider themselves as extended into the past and future and who are concerned for their happiness and accountable for their actions. Moreover, for Locke a self is a person, considered from a first-personal point of view. I show that the concept of self that he develops in the context of his discussion of persons and personal identity is richer and more complex than the I-concept that he invokes in his version of the cogito. I further argue that Locke’s moral and religious views explain why he emphasizes the need for a conceptual distinction between persons and human beings. In the final section I turn to the reception of Locke’s view by some of his early critics and defenders, including Elizabeth Berkeley Burnet, an anonymous author, and Catharine Trotter Cockburn.

Locke’s remarks about attention have not received a great deal of attention from commentators. In Section 1, I make the case that attention plays an important role in his philosophy. In Section 2, I describe and discuss five Lockean claims about attention. In Section 3, I explore Locke’s views about attention in relation to his account of sense perception. He thinks that we attend to objects by attending to ideas, and I argue that he treats sensory ideas as transparent in (...) a particular sense. In Section 4, I raise the worry that some of Locke’s remarks about attention seem at odds with his doctrine of the transparency of the mind. I offer two ways of resolving the problem, and suggest that they are parts of a single story. (shrink)

In sections 2.21.23-25 of An Essay concerning Human Understanding, John Locke considers and rejects two ways in which we might be “free to will”, which correspond to the Thomistic distinction between freedom of exercise and freedom of specification. In this paper, I examine Locke’s arguments in detail. In the first part, I argue for a non-developmental reading of Locke’s argument against freedom of exercise. Locke’s view throughout all five editions of the Essay is that we do not possess freedom of (...) exercise (at least in most cases). In the second part, I argue that, when Locke asks whether we possess freedom of specification, his question is intentionally ambiguous between two readings, a first-order reading and a higher-order reading. Locke’s view is that, on either reading, we do not possess freedom of specification (at least in any interesting sense). (shrink)

Molyneux’s question asks whether someone born blind, who could distinguish cubes from spheres using his tactile sensation, could recognize those objects if he received his sight. Locke says no: the newly sighted person would fail to point to the cube and call it a cube. Locke never provided a complete explanation for his negative response, and there are concerns of inconsistency with other important aspects of his theory of ideas. These charges of inconsistency rest upon an unrecognized and unfounded assumption (...) that seeing entails recognition. Locke’s negative answer to Molyneux’s question is consistent with his other philosophical commitments. (shrink)

In the Fifth Meditation Descartes considers the problem of knowledge preservation : the challenge of accounting for the diachronic certainty of perfect knowledge [scientia]. There are two general solutions to PKP in the literature: the regeneration solution and the infallible memory solution. While both readings pick up on features of Descartes’ considered view, I argue that they ultimately fall short. Salvaging pieces from both readings and drawing from Descartes’ virtue theory, I argue on textual and systematic grounds for a dispositionalist (...) solution. On this view, the diachronic certainty of scientia is achieved through virtuous habits of belief. (shrink)

Locke characterizes sensitive knowledge as knowledge of the existence of external objects present to the senses, and in terms of an ‘assurance’ that falls short of the certainty of intuition and demonstration. But it is unclear how this fits with his general definition of knowledge, as the perception of the agreement or disagreement of ideas, and it is unclear how that assurance can amount to knowledge, rather than amounting to mere probability (which he contrasts with knowledge). Some contend that Locke (...) does not regard sensitive knowledge as genuine knowledge, but only honourifically calls it knowledge. In contrast, I argue that Locke holds that sensitive knowledge is knowledge, though he takes the conditions for it to be very different from the conditions for intuitive and demonstrative knowledge. It is not the assurance alone which Locke thinks qualifies sensitive knowledge as such: it is also the fact that the assurance arises from the actual employment of the senses upon external objects, and the fact that the senses do not generally deceive us, which he thinks qualifies sensitive knowledge as genuine knowledge. That there is a (tacit) form of externalism in Locke's account of sensitive knowledge is the main thesis of this paper. (shrink)

This paper takes up two questions regarding Locke’s doctrine of suspension. First, what motivates suspension? Second, what are the conditions under which we are motivated to suspend? In response to the first question, I argue that suspension is motivated by the desire to avoid the possible future evils that might result from acting precipitately upon some desire without suspending. In response to the second question, I argue against the common assumption that the desire motivating suspension must be an agent’s most (...) pressing desire. (shrink)

How, if at all, does the internal structure of human phenomenological color space map onto the internal structure of objective reflectance‐profile space, in such a fashion as to provide a useful and accurate representation of that objective feature space? A prominent argument (due to Hardin, among others) proposes to eliminate colors as real, objective properties of objects, on grounds that nothing in the external world (and especially not surface‐reflectance‐profiles) answers to the well‐known and quite determinate internal structure of human phenomenological (...) color space. The present paper proposes a novel way to construe the objective space of possible reflectance profiles so that (1) its internal structure becomes evident, and (2) that structure’s homomorphism with the internal structure of human phenomenological color space becomes obvious. The path is thus reopened to salvage the objective reality of colors, in the same way that we preserved the objective reality of such features as temperature, pitch, and sourness—by identifying them with some objective feature recognized in modern physical theory.

La filosofía inmaterialista de Berkeley ha sido muchas veces infravalorada por la mala comprensión de su propuesta ontológica, específicamente por la dificultad que presenta su concepto de idea. El propósito de este artículo es, entonces, esclarecer y explicar dicho concepto porque de ello depende entender correctamente la ontología y el inmaterialismo filosófico berkeleyano. Para realizar esto 1) mostraré algunos ejemplos de la mala comprensión que ha tenido la propuesta berkeleyana, debido principalmente a su concepto de idea; 2) rastrearé cómo se (...) fue conformando dicho concepto en las notas de juventud conocidas como _Comentarios Filosóficos_; 3) analizaré y explicaré el concepto de idea a partir de la obra publicada de los _Principios_ y los _Diálogos_.
