The deconstructive work that marked the twentieth century benefited thought. Jacques Derrida's attempt to translate linguistically and semantically the Heideggerian invitation to the Destruktion of the concepts of metaphysics produced the essential result of pointing out the discards, voids, fractures, discontinuities, aporias, the ideological and "actantial" structures of the texts of the metaphysical tradition, passing beyond their intrinsically manifest and wanted unity. In fact, the deconstructionist strategy works to deprive authority of the function of system that absorbs everything by reduction to identification with itself, in order to assert otherness and difference, previously "unthinkable" in the Western philosophical tradition.
