Following the Enlightenment, the concept of ‘critique’ broadened and acquired a political denotation, in which the expression of opinion alone could itself be already considered critique. This meaning of ‘critique’ expresses acknowledgement of men as equal, free and rational. This broad concept of critique, however, also tends to negate certain more technical and specific forms. This paper goes back to conceptions of critique introduced by Kant and developed in an educational perspective by the neo-Kantian Paul Natorp. Kant's concept of critique (...) concentrated on the conditions of possibility of judgemental powers, resulting in a transcendental critique of Reason. Natorp applied this conception of transcendental critique to education. Though Natorp relates education to society as a whole, his concept of critique does not uncover the social determinants of educational views but holds on to a transcendental critical idea of critical judgement that is not completely socially determined. Consequently, in the transcendental critical approach, the critical function of Reason is given priority over any political vision. This results in a conception of critique that primarily questions validity claims, stressing rational testing as opposed to other sources of validity, such as traditional or religious authority. The transcendental critical programme, further developed in twentieth-century Germany, still endorses the implied denial of the possibility of deriving the validity of propositions from experience. It can be distinguished from Karl-Otto Apel's brand of transcendental critique by its refusal to assume any primary criterion for critical judgement, in the manner of Apel's ‘ideal communicative community’. Consequently, this programme cannot result in any positive conception of education. Its main contribution consists in exposing those presuppositions of educational views and practices that function as a priori ideas as conditions of the possibility of their justification. Though not denying the value and relevance of positive educational conceptions, this transcendental critical approach primarily aims at preventing metaphysical foundational questions from being forgotten or dogmatically fossilised.
