Category Theory
Category theory is a general mathematical theory of structures and sytems of structures. It allows us to see, among other things, how structures of different kinds are related to one another as well as the universal components of a family of structures of a given kind. The theory is philosophically relevant in more than one way. For one thing, it is considered by many as being an alternative to set theory as a foundation for mathematics. Furthermore, it can be thought of as constituting a theory of concepts. Finally, it sheds a new light on many traditional philosophical questions, for instance on the nature of reference and truth.
General Definitions
Category theory is a generalized mathematical theory of structures. One of its goals is to reveal the universal properties of structures of a given kind via their relationships with one another. Formally, a category C can be described as a collection Ob , the objects of C , which satisfy the following conditions: For every pair a b of objects, there is a collection

Short description
This book is a "missing link" between the elementary textbook of Lawvere and Schanuel "Conceptual Mathematics" and the much more advanced textbooks such as the one by MacLane and Moerdijk "Sheaves in Geometry and Logic."
Avoiding the complicated, fully fledged notion of a Grothendieck topos, whose very formulation presupposes a good deal of mathematical experience, this book introduces topos theory through presheaf toposes, i.e., readily visualizable categories whose objects result from glueing simpler ones, the "generic figures". Several phenomena which distinguish toposes from the ordinary category of sets appear already at this simpler level.
Six easy to understand examples accompany the reader through the whole book, illuminating new material, interpreting general results and suggesting new theorems.

Research Interests: I have been involved in the development of elemntary topos theory since its infancy in the early 1970s, and have written two books on the subject: "Topos Theory" (Academic Press, 1977) and "Sketches of an Elephant: a Topos Theory Compendium" (Oxford U.P., 2002). My interests focus particularly on the way in which topos theory provides a means of integrating geometric and logical ideas in the foundations of mathematics and of theoretical computer science.

Categorical logic
Categorical logic is a branch of category theory within mathematics , adjacent to mathematical logic but in fact more notable for its connections to theoretical computer science . In broad terms, it is a theory about the transition from a type theory , understood to be within an intuitionistic logic or constructive mathematics setting, to a category , by means of a translation that respects both the syntax and the intended computational meaning of type-theoretic constructions. The subject has been recognisable in these terms since about , when the needs of domain theory started to call on category theory. The earlier history is relatively complex, and contains some ironies. Categorical logic originated within sheaf theory , as a suitable version of Kripke semantics one can say with hindsight, and emerged as a theory with a character of its own only in shedding the necessary connection with sheaves. This can be traced in a number of stages, from onwards: the formulation of the Grothendieck topos , and then of the elementary topos , giving rise first to topos theory . Topos theory, as would now be understood, is the intuitionistic replacement for

See also the Categories Home Page I don't pretend to understand what category theory has to say about the foundations of mathematics, but I would rather like to understand. To that end these notes are compiled recording my impressions, such as they are, about the why Category theorists have misgivings about classical set theory as a foundation for mathematics and what (if anything) they would like to offer in its stead.

Problems for Category Theory in Classical Set Theoretic Foundations
  • Doing Category Theory in Set Theory Many categories are categories of all examples of a particular kind of mathematical structure (or of all models of a particular theory). Such collections are problematic in set theory in the same way as the set of all sets. In consistent set theoretic foundations based on the iterative conception of set they can be proven not to exist. Though there are techniques which can be employed to mitigate these difficulties, the solutions are not entirely satisfactory, and the view that set theory is not a natural context in which to do category theory may persist. For more on this kind of problem, see: Chapter 8 Introduction and Section 3 . Furthermore, certain kinds of construction which are important in category theory cannot reliably be done in set theory, for similar reasons, see
