Philosophers have long agreed that thinking is expressed in the use of language, that we “think in the medium of words.” It is also true, however, that we think in the medium of pictures, and it is likely that these two ways of thinking are interrelated; certainly, we could not think in pictures if we did not have words, and perhaps we could not use words, in principle, unless we were also engaged in some sort of picturing, at least in our imagination. An ideographic language like Chinese would give greater support to the latter possibility than would our phonetically based form of writing.

This book explores a dimension in Husserl's thought that is, unfortunately, usually neglected, the analysis of formal structures in thinking. It examines such topics as formal ontology, formal logic, logic and mathematics, set theory, and, most of all, the theme of parts and wholes. Moreover the book does not just comment on Husserl's treatment of these topics; it pursues them as philosophical issues, shows how Husserl's position can be compared with that of other thinkers, and traces some of the influence he has exercised.
