Introduction to Volume Iown structure theory of noncommutative Noetherian simple rings. Chapters 5 and 6 survey limits, limit preserving functors, additive and abelian categories, free algebras, (semi) group and polynomial algebras, and the adjoint functor theorems of Eilenberg, Freyd, Gabriel, Kan, Mitchell, and Watts. These six chapters comprise Part I.

Semisimple Modules and Homological Dimension: Every semisimple ring is isomorphic to a finite product of full matrix rings of various degrees over various fields. These rings are also characterized by the Wedderburn-Artin theorem (8.8) as right Artinian rings with no nilpotent ideals. (The condition is right-left symmetric.)
