Now the propositions of pure reason, especially when they transcend the limits of possible experience, do not admit of our making any experiment with their objects, as in natural science. Thus, while all the ambitious attempts of reason to penetrate beyond the limits of experience end in disappointment, there is still enough left to satisfy us in a practical point of view. Besides, not being founded on experience, they are not presented with any object in a priori intuition upon which, antecedently to experience, they might base their synthesis. In both these cases the principle of causality, which is valid only in the field of experience--useless and even meaningless beyond this region, would be diverted from its proper destination. This removes all pretext, if there yet remains any, for asserting that the mind is convinced by reasoning of that principle, that instances of which we have no experience, must necessarily resemble those, of which we have. When men have found by experience, that it is impossible to subsist without society, and that it is impossible to maintain society, while they give free course to their appetites; so urgent an interest quickly restrains their actions, and imposes an obligation to observe those rules, which we call the laws of justice. (7) All other objects, such as fire and water, heat and cold, are only found to be contrary from experience, and from the contrariety of their causes or effects; which relation of cause and effect is a seventh philosophical relation, as well as a natural one.
