In these challenging pages, Unger argues for the extreme skeptical view that, not only can nothing ever be known, but no one can ever have any reason at all for anything. A consequence of this is that we cannot ever have any emotions about anything: no one can ever be happy or sad about anything. Finally, in this reduction to absurdity of virtually all our supposed thought, he argues that no one can ever believe, or even say, that anything is (...) the case. (shrink)

A further development of Tye's theory of phenomenal consciousness along with replies to common objections.

In 1995, in my book, Ten Problems of Consciousness, I proposed a version of the theory of phenomenal consciousness now known as representationalism. The present book, in part, consists of a further development of that theory along with replies to common objections. It is also concerned with two prominent challenges for any reductive theory of consciousness: the explanatory gap and the knowledge argument. In addition, it connects representationalism with two more general issues: the nature of color and the location of (...) the phylogenetic dividing line between those creatures that are phenomenally conscious and those that are not.

The epistemic basing relation is the relation occurring between a belief and a reason when the reason is the reason for which the belief is held. It marks the distinction between a belief's being justifiable for a person, and the person's being justified in holding the belief. As such, it is an essential component of any complete theory of epistemic justification. ;I survey and evaluate all theories of the basing relation that I am aware of published between 1965 and 1995. (...) These include causal theories, , theories involving pseudo-overdetermination relations , theories involving what a person would appeal to in defense of her beliefs , and doxastic theories , involving an appeal to meta-beliefs. My discussion of these theories includes a detailed analysis of variations of Lehrer's case of the gypsy lawyer which, I show, can be reformulated to pose a decisive objection to causal theories, if not causal analyses, of the basing relation. ;Rejecting all published theories, I present a new kind of causal analysis of the basing relation which I call the causal-doxastic theory. This theory states that a belief is based on a reason if the reason bears an appropriate causal relation to the belief, or, it does not bear such a causal relation, but an appropriate meta-belief is present. A causal analysis of which meta-beliefs are appropriate is given, so as to count as inappropriate rationalizations, mistaken meta-beliefs, etc. In developing the causal-doxastic theory, I present a solution to the problem of deviant causal chains, a discussion of the causal sustaining of beliefs, an account of rejecting reasons, and a partial analysis of showing that one is justified. I then discuss implications of my theory regarding foundationalism, inference, basic and non-basic belief, holistic and linear coherentism, process reliabilism, internalism and externalism, and various closure principles.

"Descartes is rightly considered the father of modern philosophy" - Schopenhauer "The effect of this man on his age and the new age cannot be imagined broadly enough... René Descartes is indeed the true beginner of modern philosophy, insofar as it makes thinking the principle. "- Hegel "Descartes was the first to bring to light the idea of a transcendental science, which is to contain a system of knowledge of the conditions of possibility of all knowledge." - Kant A new (...) 2023 translation directly from the original manuscripts into English of Descartes' famous work "Rules for the Direction of the Mind" (Règles pour la direction de l'esprit). This edition contains a new introduction and afterword from the translator, as well as a timeline of Descartes' life and summaries of each of his works. Here, Descartes lays out a method for approaching problems and seeking knowledge. The importance of this work lies in the fact that it established the scientific method as a way of investigating the world, and had a significant influence on the development of modern science. This work is one of the foundational texts of Western Philosophy. (shrink)

In The Subjective View,' I defended (unoriginally) a dispositional theory of color and drew out some consequences of that theory. The dispositional theory (DT) maintains, roughly speaking, that for an object to instantiate a color property is for it to have a disposition to cause experiences as of an object having that property in normal perceivers in normal conditions. This theory has notable merits in capturing (assuming one wants them captured) the subjectivity and relativity of ascriptions of color, while allowing (...) that it is external ob- jects themselves that are colored. It makes colors both sense depen- dent and object qualifying.2 But it runs into prima facie problems in giving a plausible account of the phenomenology of color percep- tion, as I ruefully observed in my earlier book (op. cit., pp. 132-37).

"This stunning work is without question a major contribution to Cartesian studies, to the field of early modern philosophy, and to general epistemology--original, provocative, and philosophically interesting.

Abductivists claim that explanatory considerations (e.g., simplicity, parsimony, explanatory breadth, etc.) favor belief in the external world over skeptical hypotheses involving evil demons and brains in vats. After showing how most versions of abductivism succumb fairly easily to obvious and fatal objections, I explain how rationalist versions of abductivism can avoid these difficulties. I then discuss the most pressing challenges facing abductivist appeals to the a priori and offer suggestions on how to overcome them.

Researchers working on children's moral understanding maintain that the child's capacity to distinguish morality from convention shows that children regard moral violations as objectively wrong. Education in the moral domain. Cambridge: Cambridge University Press). However, one traditional way to cast the issue of objectivism is to focus not on conventionality, but on whether moral properties depend on our responses, as with properties like icky and fun. This paper argues that the moral/conventional task is inadequate for assessing whether children regard moral (...) properties as response-dependent. Unfortunately, children's understanding of response-dependent properties has been neglected in recent research. Two experiments are reported showing that children are more likely to treat properties like fun and icky as response-dependent than moral properties like good and bad. Hence, this helps support the claim that children are moral objectivists. (shrink)

René Descartes (1596-1650) is widely regarded as the father of modern philosophy. His noteworthy contributions extend to mathematics and physics. This entry focuses on his philosophical contributions in the theory of knowledge. Specifically, the focus is on the epistemological project of Descartes' famous work, Meditations on First Philosophy.
