For that which stands in connection with a perception according to the laws of the progress of experience is real. This something we cannot, following the analogy of a real substance, cogitate otherwise than as the cause of all things operating in accordance with rational laws, if we regard it as an individual object; although we should rest contented with the idea alone as a regulative principle of reason, and make no attempt at completing the sum of the conditions imposed by thought. The idea of systematic unity is available as a regulative principle in the connection of phenomena according to general natural laws; and, how far soever we have to travel upon the path of experience to discover some fact or event, this idea requires us to believe that we have approached all the more nearly to the completion of its use in the sphere of nature, although that completion can never be attained. The legislative power, whence the positive law is derived, must either be established by original contract, long possession, present possession, conquest, or succession; and consequently the positive law must derive its force from some of those principles. If at the foundation of our pure rational cognition of thinking beings there lay more than the mere Cogito--if we could likewise call in aid observations on the play of our thoughts, and the thence derived natural laws of the thinking self, there would arise an empirical psychology which would be a kind of physiology of the internal sense and might possibly be capable of explaining the phenomena of that sense. They are consequently a very improper foundation for such rigid inflexible rules as the laws of nature; and it is evident these laws can only be derived from human conventions, when men have perceived the disorders that result from following their natural and variable principles. The laws of freedom or of free will are hence termed practical laws. The investigation of nature pursues its own path under the guidance of the chain of natural causes, in accordance with the general laws of nature, and ever follows the light of the idea of an author of the universe--not for the purpose of deducing the finality, which it constantly pursues, from this Supreme Being, but to attain to the cognition of his existence from the finality which it seeks in the existence of the phenomena of nature, and, if possible, in that of all things to cognize this being, consequently, as absolutely necessary. For in this sphere action is absolutely necessary, that is, I must act in obedience to the moral law in all points.
