"Though the stupidity of men, barbarous and uninstructed, be so great, that they may not see a sovereign author in the more obvious works of nature, to which they are so much familiarized; yet it scarce seems possible, that any one of good understanding should reject that idea, when once it is suggested to him. A purpose, an intention, a design is evident in everything; and when our comprehension is so far enlarged as to contemplate the first rise of this visible system, we must adopt, with the strongest conviction, the idea of some intelligent cause or author. The uniform maxims, too, which prevail throughout the whole frame of the universe, naturally, if not necessarily, lead us to conceive this intelligence as single and undivided, where the prejudices of education oppose not so reasonable a theory. Even the contrarieties of nature, by discovering themselves everywhere, become proofs of some consistent plan, and establish one single purpose or intention, however inexplicable and incomprehensible." _Natural History of Religion_ XV.--General Corollary, in _Essays_ II. pp. 422, 3. "In many views of the universe, and of its parts, particularly the latter, the beauty and fitness of final causes strike us with such irresistible force that all objections appear (what I believe they really are) mere cavils and sophisms; nor can we then imagine how it was ever possible for us to repose any weight on them." _Dialogues concerning Natural Religion_, Part X. in _Essays_, II. 509. "The order and arrangement of nature, the curious adjustment of final causes, the plain use and intention of every part and organ; all these bespeak in the clearest language an intelligent cause or author. The heavens and the earth join in the same testimony. The whole chorus of nature raises one hymn to the praises of its Creator.... I have found a Deity; and here I stop my enquiry. Let those go farther who are wiser or more enterprising." _Ibid._ Part IV. p. 467. Hume is conspicuous amongst reasoners on Natural Theology for having distinctly comprehended Human Nature along with Nature in the cycle of its evidences. "This sentence at least," he writes, "Reason will venture to pronounce, That a mental world, or universe of ideas, requires a cause as much as does a material world, or universe of objects; and, if similar in its arrangement, must require a similar cause. For what is there in this subject which should occasion a different conclusion or inference? In an abstract view, they are entirely alike; and no difficulty attends the one supposition which is not common to both of them." _Ibid._ Part IV. p. 464.
