Philosopher-psychoanalyst Luce Irigaray claims that all inter-subjective relations are subtended by sexual difference and that forgetting this is ignoring a foundational aspect of human relations. For her, sexual difference is the particular relation to the body and to language that structures inter-subjectivity. Ernesto Spinelli, a contemporary scholar-practitioner of existential phenomenological psychology is particularly attuned to the constitution of inter-subjectivity in therapeutic praxis. An analysis of his own therapeutic praxis reveals a blind spot in his work. This blind spot prevents him from realizing certain inter-subjective possibilities in his work with clients; namely, the possibilities afforded by articulating a specifically other. Using Irigaray, Aloysius Joseph makes the case that Spinelli s therapeutic praxis can benefit from paying attention to a perceptual and a sensory economy that is rooted in the client s sexuate body and history. He suggests that this will not only revitalize Spinelli's version of existential phenomenology but also continue to adhere to its objective of challenging the cultural assumptions of our time.
