Signo y lenguaje: Acerca de la interpretación de Lafont y Apel de Ser y Tiempo

this paper is part of a wider study about apel's "transcendental hermeneutics". in that context, cristina lafont's critical approach to heidegger offers new perspectives about meaning, reference, truth and objectivity. these topics are closely connected with apel's philosophy and his distinction between constitution of meaning and justification of validity. first, we deal with what lafont calls "linguistic idealism". second, we treat lafont's criticism of being and time, particularly the question of the "sign" and the distinction "discourse-speech" (rede-sprache). in third place, we analyze the debate between lafont and carman about the linguistic or pre-linguistic character of meaning. we conclude with some questions relative to a particular conception of direct reference, which is defended by apel too.
