At the present time, there are several interpretations and modes of Kant’s transcendental philosophy (TP). Which of these interpretations and modes of transcendentalism most adequately express the spirit of TP, i.e. can claim the title of the transcendental ones? For the explication of the ‘idea of transcendental philosophy’ [KrV, A1], here I distinguish two transcendental shifts: methodological and metaphysical ones, which in their totality predetermine the essence and set the specificity of (...) class='Hi'>Kant’s transcendental idealism. The methodological transcendental shift that Kant postulates in his definitions of TP in the Critique of Pure Reason [KrV, A11; B25] represents a shift from studying of objects to the analysis and justification of our mode of cognition of objects. This shift sets a fairly wide range of a la Kantian a priori doctrines and predetermines the transcendental turn (Re–Transcendentalising) of modern philosophy. The metaphysical transcendental shift that can be correlated with “the altered method of our way of thinking [in metaphysics]” [KrV, BXVIII], is associated with the splitting of the “thing” into the actual object (or Kantian thing-in-itself) and object of experience (or Kantian appearance), and involves a transition from the study of thing-in-itself to the analysis of the appearance. More precisely, this shift finds its expression in the transcendental triad “object (thing-in-itself; Ding an sich) – appearance (Erscheinung) – representation (Vorstellung)”, which determines the ‘idea’ (essence) of transcendental idealism/metaphysics.
