The critical philosophy is a metaphilosophy, a philosophy about philosophy. Kant believed that in the practical sphere the critical method made direct contact with moral judgement and brought forth conclusions that must be accepted, even if people have an interest in denying them. ‘Englightenment and law’ addresses the philosophical questions which involved politics that Kant turned to in his last years. He was hoping that by the use of the critical method he could help settle some of the vexing question of legitimacy and right. Morality is the core of practical reason but it is not the whole of it. Law, for Kant, has the same metaphysical basis as morality, and is therefore grounded a priori in the idea of transcendental freedom.
