Borderline personality disorder is characterized as an identity disturbance or pathology of the self-structure. The author employs concepts from deconstruc tion philosophy and object relations theory to explore how persons with borderline personality disorder attempt to generate meaning, eliminat ambiguity, and maintain idealizations by assigning polarized attributions of value, agency, and motivation to their experiences. The author proposes tha these binary attributions interact to form multiple, discrete self structures or states of being. Each state is characterized by stereotyped expectations for self and other and patterns of relatedness that are self-perpetuating. The author delineates four common states, labeled as helpless victim, guilty perpetrator angry victim, and demigod perpetrator, and suggests treatment strategies t deconstruct each state and to facilitate the development of an integrated and differentiated selfJacques Derrick is considered the founder of deconstruction, a postmodern philosophy that closely examines how meaning is generated. Much of Derrida's writing is a critique of Western philosophical traditions. He points out that Western philosophy is based upon a binary system of logic, i.e. if p, then q. There is a presupposition that universal truths and essential meanings may be discovered through objective observations and logic.Derrida felt that this binary system of absolutes provided an implicit lens for how we perceive ourselves and others and how we make sense of our experiences. In binary logic, any being or entity is defined by what it is not, "which would identify it as this rather than that" (Derrida, 2004, p. 143). For example, an apple is defined by how its shape, color, and texture differ from other fruit, such as a banana. A fruit is either an apple or a banana. There is no in-between. Binary oppositions maintain an either/or -if/then proposition and are thereby able to eliminate doubt and ambiguity and to establish a certainty of meaning.By establishing a certainty of meaning, binary logic eliminates any need for individual interpretations. There is perfect concordance of understand- Derrida employed the terms logocentrism or phonocentrism to describe the Western tendency towards binary oppositions and the personal and interpersonal consequences of that tendency. Derrida felt that a need for certainty of meaning and a desire for idealized unification and perfect understanding between self and other drives logocentrism.Derrida pointed out that one of the consequences of a logocentric tendency is devaluation of contradictory evidence and exclusion of alternative meanings that do not fit within the binary structure. He argued that certainty of meaning is illusory and that "signified meaning. . .always signifies again and differs" (Derrida, 1978, p. 25). For example, an older use of the word "apple" is, as a broader term, used to describe all nuts and fruits (including bananas). "Apple" may also signify a cherished object, as in "the apple of my eye"; an object of temptation...
