Very soon after publishing 'Critique of Pure Reason', Kant's transcendental idealism became one of the most-discussed theories in German philosophy. Both supporters and opponents of Kant's idea were numerous. One of the latter was Friedrich Heinrich Jacobi, whose 'On Transcendental Idealism' gave the first really strong impulse to question the main thesis of 'Critique of Pure Reason'. Jacobi's objections to transcendental idealism are also present in many modern interpretations of Kant's theoretical philosophy. Most historians of philosophy underline that it was Jacobi who first raised the so-called problem of affection. Therefore the acquaintance with Jacobi's Kant critique and with the consequences it brought to the whole interpretation of transcendental philosophy seems to be absolutely necessary for everyone who wants to fully understand the conception of transcendental idealism and its aporias.
