Week 1 of Graduate Class by Dr Timothy WILLIAMSON : Existence, Identity and Logic

Synopsis of Course :

In spite of the Title, the Class will primarily be concerned with issues about identity. A case study will be made of the identity of the subjective character of experience and problems with the non-transitivity of indiscriminability, with some reference to observationality, sorites argumenst and “vague objects”. Techniques developed with respect to these cases will be applied to the identity of persons and species, and then to sorites arguments about identity across times and possible worlds. The nature of criteria of identity will be discused. If time permits, a comparison will be developed between first-level concepts of existence and identity, with discussion of the analogues for the former of Leibniz’s Law and the necesity of identity, and of the relation between spatio-temporal location and possession of properties as accounts of existence

Christopher PEACOCKE : Class on Concepts

Week 1

Synopsis of Course : The Class aims to address the following questions : What are concepts ? Whatis the relation between the identity of a concept and a correct account of possession of that concept ? I will be proposing a general form which should be taken by accounts of concept possession and applying this form to i) issues in the theory of reference. ii) to recent disputres in the philosophical literature about the nature of concept possession and iii) to the theory of thought and radical interpretation. I will alsobe considering the normative dimension of concepts, and with it the question of whether the use of concepts in the description of mental phenomena is consistent with a naturalistic world-view. If there is time, I may also be considering the nature of the ontology of concepts, and of the individuation of conceptual content by reference to nonconceptual representational content. Suitable reading will be suggested as we proceed.
