Abstract: Heidegger back to the origin of the fundamental question repeatedly, thissituation leads him to assert that the theming of the question of meaning, that is, thequestion of being, is directed towards of truth topic. In 1935, Heidegger checks his transitby Western ontology and writing framing under the title of “thinking history of being”(Seinsgeschichtlich). We intend to present Heidegger’s explanation of the passage or transitof truth in the origin of Greek thought as unconcealment (aletheia) and the platonic senseof truth as correspondence (omoiosis). The truth as aletheia, is the history section of thecave (which is the story of each men), a transformation by the “transit” between “seeing”( ὁ ρ ᾶ ν ) and “ visible” (νοe ῖ ν ), the transformation creates the new concept of Platonic ἰ δέα :Heidegger calls this Er-blickenheit or truth as Homoi o sis has since become adaequatio andthen ‘ agreement ’ . Study the theme of truth from an original reading by Martin Heidegger,aims noted the situation of the contemporary debate about the usual interpretation ofPlato’s doctrine. Key Word: Plato, aletheia, truth, men, Western ontology
