The analogy which you attempt to establish between the contrivances of human art, and the various existences of the Universe, is inadmissible. We attribute these effects to human intelligence, because we know before hand that human intelligence is capable of producing them. Take away this knowledge, and the grounds of our reasoning will be destroyed. Our entire ignorance, therefore, of the Divine Nature leaves this analogy defective in its most essential point of comparison.
What consideration remains to be urged in support of the creation of the Universe by a supreme Being? Its admirable fitness for the production of certain effects, that wonderful consent of all its parts, that universal harmony by whose changeless laws innumerable systems of worlds perform their stated revolutions, and the blood is driven through the veins of the minutest animalcule that sports in the corruption of an insect's[1] lymph: on this account did the Universe require an intelligent Creator, because it exists producing invariable effects, and inasmuch as it is admirably organized[2] for the production of these effects, so the more did it require a creative intelligence.
Thus have we arrived at the substance of your assertion. "That whatever exists, producing certain effects, stands in need of a Creator, and the more conspicuous is its fitness for the production of these effects, the more certain will be our conclusion that it would not have existed from eternity, but must have derived its origin from an intelligent creator."
