MISS MACDONALD, in an article in the October 1953 issue of Philosophy under the title “Linguistic Philosophy and Perception,” discusses the relationship between this philosophical school and others, by contrasting its treatment of the problem of perception with typical Realist, Dualist and Phenomenalist solutions. Her main point is that the branch of Linguistic philosophy which she represents, which she proposes to call Metaphilosophy, does not take sides on this issue, nor propound a new theory of its own, but stands back and tries to help us to understand the differences separating the various schools by a careful analysis of the language they use.
