Derrida's deconstruction of Saussure

The question of this thesis is what deconstruction is. However, Derrida doesn't express deconstruction clearly in his own texts. For this reason, we tried to follow the text -Saussure's Course in General Linguistics- that Derrida read with deconstruction item by item. By deconstruction, Derrida opens up the other facilities of the texts which Western metaphysics explained itself and of the discourse or the living spaces which can be discovered within societal, political, communicative, public and literary life aimed by this metaphysisc. As we clarified deconstruction in this thesis, we moved on Saussurean linguistics model. In the "Writing Before the Letter", the first chapher of Grammatology, Derrida studies on how Saussure maintains the writing-speech opposition of Western metaphysic. By deconstruction of Saussurean linguistics, Derrida questions the origin of the Western metaphysics and refers to possibility of deconstruction of the metaphysics of presence that has been telos of philosophy since Platon. Particularly, he pursues the concept of sign and writing on the Course in General Linguistics. We taked the concepts which of Différance, trace, event, arche-writing etc. confessed end of the deconstruction of Saussurean linguistics like that refers to 'destruction' of the Western metaphysics and concept oppositions its generated.
