330 THE GEXESIS OF SPECIES. [Chap. 



physical science in any coming century will ever approach 

 to a demonstration that countless modes of being, as 

 different from each other as are the force of gravitation 

 and conscious maternal love, may not co-exist. Two such 

 modes are made known to us bv our natural faculties 

 only : the pliysical, wliich includes the first of these 

 examples ; the hyperphysical, wliicli embraces the other. 

 For those wlio accept revelation, a third and a distinct 

 mode of being and of action is also made known ; namely, 

 the direct and immediate or, in tlie sense here given to 

 the term, the supernatural. An analogous relationship 

 nms through and connects all theses modes of being and 

 of action. The higher mode in each case employs and 

 makes use of the lower, the action of which it occasionally 

 suspends or alters, as gravity is suspended by electro- 

 magnetic action, or the living energy of an organic being 

 restrains the inter-actions of the chemical afiinities belong- 

 in o- to its various constituents. 



Thus conscious will controls and directs the exercise of 

 the vital functions according to desire, and moral con- 

 sciousness tends to control desire in obedience to higher 

 dictates.' The action of living organisms depends upon 



1 A good exposition of how an inferior action has to yield to one hi<^her 

 is given by Dr. NevNinan in his *' Lectures on University Subjects," p. 372. 



"What is true in one science, is dictated to us indeed according to that 

 science, but not according to another science, or in another depai-trm-nt. 

 "What is certain in the military art, has force in the military art, but 

 not in statesmanship ; and if statesmanshij) be a higher department of 

 action than war, and enjoins the contrary, it has no force on our reception 

 and obedience at all. And so what is true in medical science, might in all 

 cases be carried out, were man a mere animal or bnite without a soul ; but 

 since he is a rational, responsible being, a thing may be ever so true in 

 mediiine, yet may be unlawful in fact, in consequence of the higher law of 

 morals and religion coming to some dilfercnt conclusion."
