"Personality, in our sense, is a Shakespearean invention, and is not only Shakespeare's greatest originality but also the authentic cause of his perpetual pervasiveness." So Harold Bloom opines in his outrageously ambitious Shakespeare: The Invention of the Human. This is a titanic claim. But then this is a titanic book, wrought by a latter-day critical colossus--and before Bloom is done with us, he has made us wonder whether his vision of Shakespeare's influence on the whole of our lives might not be simply the sober truth. Shakespeare is a feast of arguments and insights, written with engaging frankness and affecting immediacy. Bloom ranges through the Bard's plays in the probable order of their composition, relating play to play and character to character, maintaining all the while a shrewd grasp of Shakespeare's own burgeoning sensibility. It is a long and fascinating itinerary, and one littered with thousands of sharp insights. Listen to Bloom on Romeo and Juliet: "The Nurse and Mercutio, both of them audience favorites, are nevertheless bad news, in different but complementary ways." On The Merchant of Venice: "To reduce him to contemporary theatrical terms, Shylock would be an Arthur Miller protagonist displaced into a Cole Porter musical, Willy Loman wandering about in Kiss Me Kate." On As You Like It: "Rosalind is unique in Shakespeare, perhaps indeed in Western drama, because it is so difficult to achieve a perspective upon her that she herself does not anticipate and share." Bloom even offers some belated vocational counseling to Falstaff, identifying him as an Elizabethan Mr. Chips: "Falstaff is more than skeptical, but he is too much of a teacher (his true vocation, more than highwayman) to follow skepticism out to its nihilistic borders, as Hamlet does." In the end, it doesn't matter very much whether we agree with all or any of these ideas. What does matter is that Bloom's capacious book sends us hurrying back to some of the central texts of our civilization. "The ultimate use of Shakespeare," the author asserts, "is to let him teach you to think too well, to whatever truth you can sustain without perishing." Bloom himself has made excellent use of his hero's instruction, and now he teaches us all to do the same. --Daniel Hintzsche
