# Categories Without Sets?

Does anyone know of a book on Category Theory that purposely attempts to teach category theory without explicitly basing it upon set theory?

See http://www.cs.man.ac.uk/~hsimmons/BOOKS/CatTheory.pdf" [Broken]. Also the appendix on Foundations in MacLane's Categories for the Working Mathematician is a direct presentation.

Ah, yes, I see that MacLane's book does indeed include such a section; thank you!
