Metaphysical Proofs of the Existence of God are not within Everybody's reach. I cannot open my eyes without admiring the art that shines throughout all nature; the least cast suffices to make me perceive the Hand that makes everything. Men accustomed to meditate upon metaphysical truths, and to trace up things to their first principles, may know the Deity by its idea; and I own that is a sure way to arrive at the source of all truth. But the more direct and short that way is, the more difficult and unpassable it is for the generality of mankind who depend on their senses and imagination.
