Fusion Theory Interpretation of Kant's OIC Principle
Kant's OIC moral principle is inseparable from Kant's philosophical context of distinguishing the two worlds,and the real meaning of"can"in OIC principle is the self-discipline of the will rather than the ability to act from practical reason in the phenomenal world.The comprehensive interpretation that integrates the subjective idea theory and the objective effect theory shows the connection be-tween the two worlds,and also makes Kant's ethics more realistic.The fact that the OIC principle arises together and is ultimately com-patible with both worlds shows that this ethical principle is also acceptable in practice.
