Abstract

: This paper examines two features of Kant’s 1768 critique of Leibniz’ conception of space. Firstly, Leibniz’ proposed geometrical calculus called ‘analysis situs’; secondly, Leibniz’ relational conception of space. The main thesis of the paper is that Kant’s arguments are more powerful than generally recognized. With regard to the analysis situs, I will show that Kant was quite well informed about this proposed science and that his arguments severely undermine Leibniz’ claims to what it could perform. With regard to the relational theory of space, Kant’s argument would require Leibniz to present a complex story about the relation between God’s act of creation and our spatial experience to defend his relational view, rather than using the simple principle of sufficient reason.
