VAST A1TLIC ABILITY OF THE FRINCirLE. 57 



reacted on other forms of literature and on each other. 

 The influence which a new school of Painting as that of 

 the pre-Raffaelites exercises upon other schools ; the hints 

 which all kinds of pictorial art are deriving from Photo 

 graphy ; the complex results of new critical doctrines, aa 

 those of Mr. Ruskin, might severally be dwelt upon as 

 displaying the like multiplication of effects. But it would 

 needlessly tax the reader s patience to pursue, in their 

 many ramifications, these various changes : here become 

 so involved and subtle as to be followed with some diffi 

 culty. 



Without further evidence, we venture to think our case 

 is made out. The imperfections of statement which brevity 

 has necessitated, do not, we believe, militate against the 

 propositions laid down. The qualifications here and there 

 demanded would not, if made, affect the inferences. 

 Though in one instance, where sufficient evidence is not 

 attainable, we have been unable to show that the law of 

 Progress applies; yet there is high probability that the same 

 generalization holds which holds throughout the rest of 

 creation. Though, in tracing the genesis of Progress, we 

 have frequently spoken of complex causes as if they were 

 simple ones ; it still remains true that such causes are far 

 less complex than their results. Detailed criticisms can 

 not affect our main position. Endless facts go to show 

 that every kind of progress is from the homogeneous to 

 the heterogeneous ; and that it is so because each change 

 is followed by many changes. And it is significant that 

 where the facts are most accessible and abundant, there 

 are these truths most manifest. 



However, to avoid committing ourselves to more than 

 is yet proved, we must be content with saying that such 

 are the law and the cause of all progress that is known to 

 as. Should the Nebular Hypothesis ever be established, 

 then it will become manifest that the Universe at large,
