Universal Principle of Right.

‘Every Action is right which in itself, or in the maxim on which it proceeds, is such that it can co-exist along with the Freedom of the Will of each and all in action, according to a universal Law.’

If, then, my action or my condition generally can co-exist with the freedom of every other, according to a universal Law, any one does me a wrong who hinders me in the performance of this action, or in the maintenance of this condition. For such a hindrance or obstruction cannot co-exist with Freedom according to universal Laws.

It follows also that it cannot be demanded as a matter of Right, that this universal Principle of all maxims shall itself be adopted as my maxim, that is, that I shall make it the maxim of my actions. For any one may be free, although his Freedom is entirely indifferent to me, or even if I wished in my heart to infringe it, so long as I do not actually violate that freedom by my external action. Ethics, however, as distinguished from Jurisprudence, imposes upon me the obligation to make the fulfilment of Right a maxim of my conduct.

The universal Law of Right may then be expressed, thus: ‘Act externally in such a manner that the free exercise of thy Will may be able to co-exist with the Freedom of all others, according to a universal Law.’ This is undoubtedly a Law which imposes obligation upon me; but it does not at all imply and still less command that I ought, merely on account of this obligation, to limit my freedom to these very conditions. Reason in this connection says only that it is restricted thus far by its Idea, and may be likewise thus limited in fact by others; and it lays this down as a Postulate which is not capable of further proof. As the object in view is not to teach Virtue, but to explain what Right is, thus far the Law of Right, as thus laid down, may not and should not be represented as a motive-principle of action.
