advantages injurious to the other sections of the people, the first effect will be an injury to those other portions of the nation, and the second a re-active injury to the injurers, making their guilt their punishment. And so when one nation commits an aggression upon the property or rights of another, or even pursues towards it a sordid or ungracious policy, the effects are sure to be redoubled evil from the offended party. All of these things are under laws which make the effects, on a large range, absolutely certain; and an individual, a party, a people, can no more act unjustly with safety, than I could with safety place my leg in the track of a coming wain, or attempt to fast thirty days. We have been constituted on the principle of only being able to realize happiness for ourselves when our fellow-creatures are also happy; we must therefore both do to others only as we would have others to do to us, and endeavour to promote their happiness as well as our own, in order to find ourselves truly comfortable in this field of existence. These are words which God speaks to us as truly through his works, as if we heard them uttered in his own voice from heaven. It will occur to every one, that the system here unfolded does not imply the most perfect conceivable love or regard on the part of the Deity towards his creatures. Constituted as we are, feeling how vain our efforts often are to attain happiness or avoid calamity, and knowing that much evil does unavoidably befall us from no fault of ours, we are apt to feel that this is a dreary view of the Divine economy; and before we have looked farther, we might be tempted to say, Far rather let us cling to the idea, so long received, that the Deity acts continually for special occasions, and gives such directions to the fate of each individual as he thinks meet; so that, when sorrow comes to us, we shall have at least the consolation of believing that it is imposed by a Father who loves us, and who seeks by these means to accomplish our ultimate good. Now, in the first place, if this be an untrue notion of the Deity and his ways, it can be of no real benefit to us; and, in the second, it is proper to inquire if there be necessarily in the doctrine of natural law any peculiarity calculated materially to affect our hitherto supposed relation to the Deity. It may be that while we are committed to take our chance in a natural system of undeviating operation, and are left with apparent ruthlessness to endure the consequences of every collision into which we knowingly or unknowingly come with each law of the system, there is a system of Mercy and Grace behind the screen of nature, which is to make up for all casualties endured here, and the very largeness of which is what makes these casualties a matter of indifference to God. For the existence of such a system, the actual constitution of nature is itself an argument. The reasoning may proceed thus: The system of nature
