 The ideality and reality of space bear a different significance for Kant than they do for Leibniz and Clarke. For Kant, asking whether something is real or ideal concerns its status vis-à-vis the mind. One of Kant’s most explicit discussions of realism and idealism appears in the Fourth Paralogism (A368–380), where he is concerned with the possible mind-dependent status of objects and with the status of our knowledge of their existence. Although it is clear that Kant is discussing the status of spatial objects vis-à-vis the mind, in part by discussing the relation of space and time to the mind, there is no treatment here of the status of space and time vis-à-vis objects per se.
