Strawson's discussion of the concept of a person does seem to allow for the possibility of there being immaterial persons. Nevertheless his insistence that the concept of a person is the concept of a type of entity such that both predicates ascribing states of consciousness and predicates ascribing corporeal characteristics … are equally applicable to a single individual of that single type suggests that he is conflating the concept of a human being, in the technical sense of homo sapiens , (...) and the concept of a person.

The Editor-in-Chief would like to thank the following colleagues who have helped maintain ….

Copi, Quine and van Heijenoort have each claimed that there are two fundamentally different kinds of logical paradox; namely, genuine paradoxes like Russell's and pseudo-paradoxes like the Barber of Seville. I want to contest this claim and will present my case in three stages. Firstly, I will characterize the logical paradoxes; state standard versions of three of them; and demonstrate that a symbolic formulation of each leads to a formal contradiction. Secondly, I will discuss the reasons Copi, Quine and van (...) Heijenoort have given for the distinction between genuine and pseudo-paradoxes. Thirdly, I will attempt to explain why there is no such class as the class of all and only those classes which are not members of themselves. (shrink)
