Aug 27, 2012 at 7:12 comment added David Roberts Conjugation in a group $G$ is merely a natural isomorphism between homomorphism with codomain $G$, thought of as a functor between one-object groupoids. This is in keeping with category-theoretical philosophy that things should only be determined up to isomorphism if there is really no good way to choose between a number of choices.
