The purpose of this essay is to consider some of the practical implications of Martin Heideger's view that "Language is the house of Being," for the academic study of cultural transformation and intercultural communication. The paper describes the ontological basis of Heidegger's work, and the inquiry into Being, and contains sections on "Speaking Being Interculturally,""Saying,""The Unsaid,""The Transformation of Culture," and "Language and Counterculture." The paper attempts to show that the world is always shaped by language, and that its fundamental contingency may not be directly experienced until the experiential world of everyday experience is deconstructed as it can be by the use of psychedelic drugs. It also presents the Heideggerian view that cultural transformation must be accomplished by an indigenous thinking, and that, for example, the promises of Eastern mysticism for European and American youth during the sixties were ultimately unfulfilled since the ontological environment of Western culture, the roots which the European concepts traced could not reach the wellspring. Seventy notes are included. (PRA)
