inference quotes

Suppose I had found a watch upon the ground, and it should be enquired how the watch happened to be in that place† The inference, we think, is inevitable; that the watch must have had a maker, that there must have existed, at some time and at some place or other, an artificer or artificers, who formed it for the purpose whichwe find it actually toanswer; who comprehended its construction, and designed its use.
