Vice Versa: Bisexuality and the Eroticism of Everyday Life by Marjorie Garber
OUT OF PRINT
"For all the finger-pointing, name-calling and ludicrous efforts at categorization, what is a bisexual? The great strength of "Vice Versa" is that Garber doesn't tell you--exactly. Bisexuality is comprehensively explored but never pinned down. For example: "Bisexuality means that your sexual identity may not be fixed in the womb or at age two, or five. Bisexuality means you may not know all about yourself at any given time.'
"Marjorie Garber, an English professor at Harvard and author most recently of "Vested Interests: Cross Dressing and Cultural Anxiety," has written a book that is academic in tone, with occasional personal references. She posits three mythological types of bisexuality, "as experience (Tiresias), as essence (Hermaphroditus), and as desire (Aristophanes' fable in Plato's 'Symposium').'"
