METAPHYSICS SHOULD BE STRICT SCIENCE AND CONTAIN NO ARBITARINESS.

Kant raises the question wether a science of metaphysics with a logical structure like that of the well-established mathematical and natural sciences is possible. These latter have acquired a scientific character on account of the universal rules, the synthetic a priori judgments, which they employ. Since these rules are applicable only within the limits of possible experience, metaphysics, which aims at the transcendent, is impossibility. The passion for law, for rule, dominates Kant’s philosophy. Rule expresses truth and justifies conduct. An action is right if we so act that the principle of it can be made general rule.
