Query: An artistic credo well worth reading

While Mamet's booklet is essentially an exposition of opinions with little or no discourse, it is extremely thought provoking and provides ample fuel for thinking about drama - and art in general - as lying at the edge of reason.In a treatise that mirrors the three act structure he discusses, Mamet eloquently puts forth the idea that much of political drama, by instructing us what to think and feel, is mere melodrama and that "the theatre exists to deal with problems of the soul, with the mysteries of human life, not with its quotidian calamities." He assails avant-garde artists for taking "refuge in nonsense" and electing themselves "superior to reason," yet also criticizes the "hard-bitten rationalist who rails against religious tradition, against the historical niceties, against ritual large and small.""Three Uses of the Knife" is a book that will be read quickly, but will stick to the back of your mind for sometime afterwards.
