Takes the student step-by-step through the intellectual problems of Medieval thought, explaining the principal lines of argument from Augustine of Hippos to the sixteenth century.
I started reading this because in the first chapter Martin not only explains what philosophy is and what the Middle Ages are, but also what in introduction is; not many books take the time to do that and I was impressed. Martin goes on to explain the Augustinian tradition of authority (which started with faith and sought to incorporate secular knowledge), the Aristotelean tradition that challenged it, and the resulting fall out of no authorities. There was hardly a dull page in the whole book; it kept me glued to the very end.
