Medieval Philosophy [PDF ebook] 

Philosophers of the Middle Ages endeavored to reconcile two seemingly incompatible concepts: religion and reason. By drawing extensively from the work of their predecessors, like Plato and Aristotle, medieval philosophers were able to find logical bases for their theological beliefs, thus using rationality to better comprehend their faith. This fascinating volume looks at the individuals who pioneered these new schools of thought and their lasting effects on our understanding of the nature of reality.
