Most contemporary readings of Derrida’s work situate it within a transcendental tradition of philosophical enquiry explicitly critical of naturalistic accounts of knowledge and mind. I argue that Derrida provides the naturalist with some of the philosophical resources needed to rebut transcendental critiques of naturalism, in particular the phenomenological critiques which derive from Husserl’s philosophy. I do this by showing: a) that Derrida’s account of temporality as differance undermines phenomenological accounts of the meaning of naturalistic theories and assumptions; and b) that (...) it is itself both usable and interpretable within the naturalistic framework of current cognitive science.
