  Important though the general concepts and propositions may be with which the modern and industrious passion for axiomatizing and generalizing has presented us, in algebra perhaps more than anywhere else, nevertheless I am convinced that the special problems in all their complexity constitute the stock and core of mathematics, and that to master their difficulties requires on the whole the harder labor.——Herman Weyl

  In writing the book, I tried to follow these definitions:1. The basic examples should precede the abstract definitions.2. Technical points should be presented only if they are used elsewhere in the book.3. All topics should be important for the average mathematician.
