 Since Karl Ameriks’ classic survey of the literature, Ameriks (1982), it has been customary to divide interpretations of transcendental idealism into “two object” readings and “one object” readings. By contrast, this article has been organized around the distinction between phenomenalist readings, and non-phenomenalist dual-aspect readings. This section explores the relation between the “one object”/“two object” distinction and the phenomenalist/non-phenomenalist distinction among different interpretations of Kant’s idealism.
