was the argument by which some of the ancient philosophers proved that there is one only eternal and independent Principle, the Fountain of being and the Author of all things. _Pythagoras_ called it a _Monad_; and _Aristotle_ argued from the phænomena that all things are plainly co-ordered, to one, the whole world conspiring into agreeing harmony: Whereas, if there were many independent principles, the system of the world must needs have been incoherent and inconspiring; like an ill-agreeing _drama_, botched up of many impertinent _intersertions_. And he concludes that things are well administered, which they could not be under the government of many, alluding to the verse in _Homer_, Ουκ αγαθον Πολυκοιρανιη, εις Κοιρανος εστω. “_3dly_, The condition and order of inferior, derived, and evidently dependent intelligent agents shew not only intelligence, but unity of intelligence, in the Cause of them. Every man, a single active conscious self, is the image of his Maker. There is in him one undivided animating principle, which in its perceptions and operations runs through the whole system of matter that it inhabits; it perceives for all the most distant parts of the body; it cares for all, and governs all, leading us, as a resemblance, to form an idea of the one great quickening Spirit, which presides over the whole frame of nature, the spring of motion and all operation in it, understanding and active in all the parts of the universe, not as its soul indeed, but as its Lord, by whose vital directing influence it is, though so vast a bulk, and consisting of so many parts, united into one regular fabric. Again, the general apparent likeness which there is among all the individuals of the human kind is a strong evidence of their being the children of one Father. I do not mean principally the similitude of the exterior form, (though even that, in reason, should be attributed to the direction of one intelligent Cause,) but that whereby we are especially God’s offspring, our intellectual capacities, which as far as we can judge are very nearly alike. A great difference there may be, no doubt there is, in the improvement of them; but the powers themselves, and all the original modes of perception, in the different individuals of mankind, seem to resemble each other, as much as any real distinct things in nature. Now from a multitude, or a constant series of similar effects which do not arise from necessity, we infer unity of design in the Cause. So great a number of rational beings as the whole human race, disposed of in the same manner, endued with like faculties and affections, having many, and those principal things in their condition, common, provided for out of the same fund, and made for the same purposes, may reasonably be supposed to belong to one family, to be derived from the same origin, and still under the same paternal care.
