 The argument of the Transcendental Deduction, and its relation to the Transcendental Aesthetic (and thus to Kant’s philosophy of Mathematics), is a central area of dispute between Sensibilism and Intellectualism (Waxman 1991; Longuenesse 1998; Allais 2016: §1.5; Golob 2016b; Allais 2017b). Critics charge that Sensibilism at best renders ineffectual Kant’s apparent strategy for demonstrating the legitimacy of the categories in the argument of the Transcendental Deduction and at worst shows Kant to be totally confused in his argumentative strategy (Ginsborg 2008: 68–69; Griffith 2012; Gomes 2014; Land 2015a; cf. Hegel 1977: 69–72; Pippin 1989: 29–31; Keller 1998: 107–112, 254; McDowell 2004, 2007a). However, since interpretation of the argument of the Deduction is at least as controversial as any claim made by either side of the dispute, dialectical traction on the basis of the text of the Deduction itself is difficult to come by.
