This book is already a classic, but one must realize what were the circunstances of its composition. _The Greeks and The Irrational_ was, above all, a development of the Sather lectures given by Mr. Dodds in Los Angeles during the 50s - i.e., at the time of McCarthy and the hysteria over the preservation of the supposedly eternal "Rational Values" of Western Civilization. Dodds wants, above all to warn his readers about how fragile the tradition of rational philosophical enquiry is, and how easily it can degenerate, given the power of what he calls the "Inherited conglomerate". The hub of the book, therefore, resides in the fact that Dodds remarks that the Greeks developed their philosophical and scientific tradition between the Vth and the IIIrd centuries BC and that - contrary to what the moderns would expect expectations - that tradition, before an onslaught of mysticism, simply floundered, having to be recovered painstakingly in the Late Western Middle Ages. Having this in mind, one could profit better from this outstanding work.
