128 The Evolution Hypothesis. 



it has no claim to universality, and e\ 7 olution fails in 

 the accomplishment of its task. The great central 

 fact still stands apart: the unification of knowledge 

 is not complete. The appearance in the universe of 

 a being who can say, / am, is the one fact which, if 

 left unaccounted for, renders any theory worthless, as 

 a complete interpretation of the universe. Do the 

 causes in operation in the knowable, antecedent to 

 man's appearance in the universe, give an adequate 

 explanation of the origin of mind ? We shall, subse- 

 quently, at some length, discuss the proposed solution, 

 and show that it leaves out of view the most essential 

 features of the phenomenon. It will be found to deal 

 with that which lies circa hominem, rather than in 

 hovnine. When a human mind awoke to conscious- 

 ness of itself and its environment, there occurred an 

 event not explicable by the laws of physical causation. 

 No dynamic principle will cover it. A new realm of 

 existence is revealed, wholly diverse from that ruled 

 by the laws of matter and motion : it is the realm of 

 being conscious of itself, of being whose characteristic 

 attribute is Thought. 



Before it will be possible to admit that the cosmos- 

 contains within itself all the causes of all knowable 

 phenomena, these unmistakable exceptions must be 

 explained ; these separating lines obliterated ; these 

 large classes of facts brought within the grasp of 

 physical causation: or we shall have to widen the 

 conception of the universe until it include all con-
