Thirst for speeches proposes a reading of Plato s Symposium that follows as a thread the identification of a metaphor: speech as wine. The hypothesis consists in postulating a strategic use of this image to describe the nature and the effects of speech, lógos, as an object and mode of expression of erotic desire, eros. The dissertation endeavors to map the development of this metaphor based on specific dramatic and lexical elements, representative of the way the characters act, interact, and express themselves in the drunken atmosphere of a symposion. Interpreted in light of this strategy, the Symposium emerges as a dialogue that is not only concerned with the philosophical conditions of the emission and reception of discourse, but also has a specific theoretical vocabulary to describe these in opposition to others. The heuristic and hermeneutic values of the methodology founded on the metaphor of wine are, precisely, in making explicit and contextualizing this vocabulary, which opposes, simultaneously, two types of desire and two types of discursive praxis. Both desires and praxeis are systematized into two dichotomous pairs: on the one hand, a passive-acquisitive appetitive paradigm of filling vs. emptying; on the other hand, an active-poietic erotic paradigm of lack vs. inventiveness. The difference between them pertains to the posture of the desiring subject vis-à-vis the object: while the former consumes, intro-verts, the latter creates, extro-verts. In other words, it is the difference between an appetite for speeches and an eros for wisdom.
