Old Summary of Derrida's Speech and Phenomena
According to Derrida Husserl's transcendental reduction presupposes pre-existent forms that if we analyze them deeper are actually based on ambiguous signs, and a repeatable self that can present the forms, but the self and the forms are caught in various forms of linguistic, material, and temporal externality which for the latter Husserl himself suggests by his notion of the past and anticipation of the future being part of the present in his phenomenological analysis of time. Derrida criticizes what he sees as a dualism of material speech and teleological meaning incarnating into the speech by pointing out speech can express things beyond formal meaning and that the teleological meaning of forms is differed in a network of signification and interpreted by intuitional sense pointing out two contents can have the same sense while gesturing at the same object somewhat predicting hyperintensionality from what I have heard of that concept oddly enough lol Even the self or I for Derrida presupposes its repeatability and thus the ego must have an openness to something beyond the immediacy of speech hearing form mastering content or sound meaning there is a trace of the past and anticipated future in each presence. Also the I as a sign of life (I am alive = I am not dead) presupposes death for it to have a meaning, and if the forms are to be repeatable beyond death and thus have an indefinite eternal meaning, then phenomenology according to Derrida makes a metaphysical claim of their existence beyond the self's defining life that supposes their own meaning and an other which can hear the meaning which ties into what Derrida sees as an internality of the reduction to the requiring the trace of the external, which Derrida thinks requires some sort of valuation of the external of being correct when it fulfills teleological meaning which I think Derrida sees as being an imposition.
