 What is missing from all these studies of Sanches who posit him as precursor of this or that major philosopher—from Braga (1881) to Bullón y Fernández (1905), Menéndez y Palayo (1918), and Fernando A. Palacios (1972: 23–28) to Carlos Mellizo (1982: 52–64)—is a certain lack of rigor. More fruitful would be to consider Sanches as a representative of modern scepticism with roots going back to ancient scepticism—someone whose form of scepticism impacted modern philosophy, even in cases where it went unacknowledged, as in the case of Kant. To this point, Dumont writes that Kant’s silence was historical in his dismissal of Pyrrhonist and Academic scepticism; in his lack of knowledge regarding Sextus Empiricus; and in designating Hume as the only author representative of scepticism (1972: 73): as though Hume was not himself responding to sceptics like Sextus Empiricus or Carneades. But as M.F. Burnyeat explains in “The Sceptic in his Place and Time”, in Kant’s silence regarding the sceptics, scepticism itself became “the name of something internal to the philosopher’s own thinking, his alter ego as it were” (1987: 35).
