Postulates of Evolution. 1 1 5 



Suppose the primal form to be limited and hetero- 

 geneous. Then in going back to search for an ex- 

 planation of heterogeneity, we are driven to posit 

 heterogeneity as our starting point. We begin with 

 an imperfect unification of the first matter. The law 

 of continuity is violated at the first step : the stream 

 whose divisions are to be traced back to unity is 

 assumed to be divided at the outset. If the hetero- 

 geneity which we posit be that of law as at present 

 operative, we have made no approach towards unifi- 

 cation of knowledge. If the heterogeneity be inde- 

 terminate and lawless, science can never rest in any 

 assured confidence that the best established generaliz- 

 ations may not be overturned. Law is, in that case, 

 strictly limited to the bounds of observation. A 

 finite heterogeneity does not furjiish a starting point 

 from which to work out the complete unification of 

 scientific knowledge. 



Whether regarded as homogeneous or heterogeneous, 

 when we think the cosmos as finite, we circumscribe 

 it within a limit. Beyond that limit no force by 

 hypothesis exists. If force existed anywhere beyond, 

 it would necessarily stand related to the cosmic force, 

 affecting it and being affected by it ; and the cosmic 

 force is on the supposition wholly insphered within 

 itself. Considering the force then as bounded, we 

 must think it as enclosed within a boundary line, 

 within which all being is included, and beyond it not- 

 being. Let us try to realize in thought this concep-
