Prior to encountering category theory, Bourbaki had a notion of isomorphism but no general notion of morphism.
Perhaps relevant (categories vs Bourbaki) is my memory that Sammy Eilenberg told me he and Chevalley invented the words injective, surjective and bijective (as pertaining to functions) while strolling along a beach. Also I heard Dieudonné admit that Bourbaki would have profited at least from the categorical notion of duality. ==Ross [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
