Abstract
The purpose of this article is to discuss the role of philosophy in the historiographical research in mathematics education. For this purpose, we make the therapeutic grammatical philosophy of Austrian philosopher Ludwig Wittgenstein act with the deconstructionist philosophy of French-Algerian philosopher Jacques Derrida, especially in reference to an aphorism of Wittgenstein's Philosophical Investigations comparing our language to an ancient city.
Keywords:
