Nothing can be more certain than that Dr Paley would have held the design argument to have been in no degree weakened by the theory of evolution, and that he would have been very much astonished by Professor Huxley's remarks on that argument. In referring to the mechanism of a watch as an evidence of intelligence in its maker, Dr Paley pointed out that our idea of the greatness of that intelligence would be much increased if watches were so constructed as to give rise to other watches like themselves. He must necessarily have admitted that the watch imagined by Professor Huxley was still more remarkable, and implied a still greater intelligence in its contrivance. The revolving barrel must have had wonderful capabilities, which only intelligence could confer. All the circumstances in which it was to be placed must have been foreseen, and all the influences which were to act upon it must have been taken into account, which could only be done by intelligence. All that helped variations in the direction of an accurate time-keeper must have been brought into requisition, and all that hindered it, or favoured variations in other directions, must have been detected and checked; but no unintelligent agents can be conceived of as accomplishing such work, or as more than the means of accomplishing it employed by a providential Reason. The greater the distance between the revolving barrel and the most elaborated watch--the greater the number of mechanisms between the first and the last of these two terms, or between the commencing cause and the final result--the greater the necessity for a mind the most comprehensive and accurate, to serve as an explanation of the entire series of mechanisms and the whole process of development.
