Now, without considering what is to be said in particular to the several parts of this train of folly and extravagance, what has been above intimated, is a full direct general answer to it; namely, that we may see beforehand that we have not faculties for this kind of speculation. For though it be admitted that, from the first principles of our nature, we unavoidably judge or determine some ends to be absolutely in themselves preferable to others, and that the ends now mentioned, or if they run up into one, that this one is absolutely the best; and consequently that we must conclude the ultimate end designed, in the constitution of nature and conduct of Providence, is the most virtue and happiness possible; yet we are far from being able to judge what particular disposition of things would be most friendly and assistant to virtue; or what means might be absolutely necessary to produce the most happiness in a system of such extent as our own world may be, taking in all that is past and to come, though we should suppose it detached from the whole things. Indeed we are so far from being able to judge of this, that we are not judges what may be the necessary means of raising and conducting one person to the highest perfection and happiness of his nature. Nay, even in the little affairs of the present life, we find men of different educations and ranks are not competent judges of the conduct of each other. Our whole nature leads us to ascribe all moral perfection to God, and to deny all imperfection of him. And this will forever be a practical proof of his moral character, to such as will consider what a practical proof is; because it is the voice of God speaking in us. Hence we conclude, that virtue must be the happiness, and vice the misery, of every creature; and that regularity and order and right cannot but prevail finally in a universe under his government. But we are in no sort judges, what are the necessary means of accomplishing this end.
Let us then, instead of that idle and not very innocent employment of forming imaginary models of a world, and schemes of governing it, turn our thoughts to what we experience to be the conduct of nature with respect to intelligent creatures; which may be resolved into general laws or rules of administration, in the same way as many of the laws of nature respecting inanimate matter may be collected from experiments. Let us compare the known constitution and course of things with what is said to be the moral system of nature; the acknowledged dispensations of Providence, or that government which we find ourselves under, with what religion teaches us to believe and expect; and see whether they are not analogous and of a piece. Upon such a comparison it will, I think, be found that they are very much so: that both may be traced up to the same general laws, and resolved into the same principles of divine conduct.
