64 The Evolution Hypothesis. 



unknowable power and the knowable in which it is 

 revealed ; if any new force has emerged out of, or any 

 manifestation of force has sunk again into, the in- 

 scrutuble ; if there has arisen any new mode of 

 activity which did not exist implicitly in the primal 

 totality of the conditioned ; if any form of being or 

 forth-going of energy has welled up out of the depths 

 of the incomprehensible, the system which Mr. Spencer 

 has constructed with so much learning and labour is 

 disintegrated and dissolved his evolution has ended in 

 dissolution ; for it is essential to his philosophy that 

 the relation between the unknowable actuality and 

 knowable appearance remain for ever fixed and con- 

 stant that the same quantity of the absolute energy 

 be emergent from age to age, ever equal in its sum, 

 neither less nor more. Doubt of this postulate is 

 doubt of the Evolution Philosophy; to doubt a 

 critical examination leads us, and through doubt to 

 denial.
