But Derrida's movement, i.e., deconstruction in its various forms, bothers me for what it represents-- a clunky modern Western attempt at nonessentialistic, nondualistic thinking that (1) was already done better in certain aspects of Greek thought and (2) was certainly better presented in religious traditions like Buddhism, or in the often-subversive thought of a classic like the Chuang Tzu.
