What is Category Theory?
Theory at McGill A personal account by Marta Bunge.
Theory - an expository article by Jean-Pierre Marquis from the Stanford Encyclopedia of Philosophy.
Logic, an entry by Joachim Lambek from the Encyclopaedia of
another article from the Encyclopaedia of Mathematics (Springer).
Quantization, and Much More - an introduction by John Baez. (You
might also explore his series "This Week's Finds in Mathematical
Physics" which often has references to
category theory, and particularly
theory and more
n-category theory. You can also look at these slides:
