234 THE GOSPEL, AND THE SOCIAL CEEED OF SCIENCE. 



the phenomena of the social world.* At the summit of 

 the series of living beings, Science encounters man, the 

 most complex and finished product of life, furnishing the 

 subject of the two co -related sciences of physiology and 

 psychology. In man Science finds two systems, a bodily 

 and a mental one, totally dissimilar and yet wonderfully 

 fitted together, and working into each other, as an 

 existent fact; a wonderful and indissoluble union, form- 

 ing the marvellous whole the man himself, with a 

 bodily organism capable of movements the most express 

 and admirable, and with a mind capable of producing 

 the most wonderful thoughts ; in " action like an angel, 

 in apprehension like a God." The physiologist discovers 

 in the living human body a system far more truly 

 wonderful than any solar or sidereal system moved only 

 by physical forces a system in which the parts are 

 variously and exquisitely adapted to each other and to 

 the whole, with mutual actions and sympathies, subtly 

 transmitted between parts ajacent and parts remote, and 

 between the total bodily and total mental systems them- 

 selves, all conspiring to the common final ends of life, 

 movement, and thought. Here, too, Science finds laws, 

 both of bodily function and of mental faculty, of structure 

 and growth, of mutual action of parts, and of secret 

 nervous communication. From the cunning disposition 

 of the elementary atoms and cells, to the finished physio- 

 logical functions and anatomical relations of the full- 

 grown organism ; from the first faint dawn of infant or 



* As a matter of fact, the three orders of inquiry have been carried 

 on contemporaneously, both under the Greek and modern civilizations. 

 The above is, no doubt, the order of complexity ; but whether it is the 

 order of difficulty, as Comte and Spencer and Mill affirm, may be made 

 a question. Political economy and sociology, so far as they are sciences, 

 do not seem more difficult than the physical sciences in the deductive 

 stage, which draw on all the resources of the mathematical sciences as 

 well as on experiment* -
