Resumen: In this chapter, the author discusses influential perspectives on language and discourse in the modern era (in Nietzsche, analytic philosophy, Wittgenstein, Ogden and Richards, etc.) focussing on the underlying epistemological attitude of suspicion. Coseriu¿s critique of the polar-opposite attitudes of overconfidence (logicism) and excessive suspicion (antilogicism) with respect to language is analyzed. The conclusion comprises an overview of various contemporary formulations of a general principle of trust, referred to variously by renowned scholars as the cooperative principle (Grice), the principle of trust (Coseriu), and the principle of relevance (Sperber and Wilson)
