But suppose I had found a watch upon the ground, and it should be inquired how the watch happened to be in that place, I should hardly think of the answer which I had before given,—that, for anything I know, the watch might have always been there. Yet why should not this answer serve for the watch as well as for the stone?... For this reason, and for no other, viz., that, when we come to inspect the watch we perceive (what we could not discover in the stone) that its several parts are famed put together for a  purpose ... This mechanism being observed ... the inference, we think, is inevitable, that the watch must have had a maker ... who comprehended its construction, and designed its use.                                            – William Paley
 
   There is no subject in which the tendency ... is so great, as that of natural history applied to the proof of an intelligent Creator.... I take my stand in human anatomy: and the examples of mechanism ... which it supplies, are the pivot upon which the head turns, the ligament within the socket of the hip-joint, the pulley or trochlear muscles of the eye, the epiglottis, the bandages which tie down the tendons of the wrist and instep, the slit or perforated muscles at the hands and feet, the knitting of the intestines to the mesentery, the course of the chyle into the blood, and the constitution of the sexes as extended throughout the whole of the animal creation.                – William Paley
