 which certainly involves the implication that con- 

 sciousness is an operative element in the process of 

 evolution, and that in so far as consciousness is a 

 manifestation of the unknowable diverse from its 

 manifestations in matter and motion, the dynamic 

 movement is directed from a source extern to it. 



The salient characters by which the two orders are 

 discriminated are seven. " Manifestations of the one 

 order are vivid and those of the other are faint. 

 Those of the one order are originals, while those of 

 the other are copies. The first form with one another 

 a series or heterogeneous current, that is never broken ;. 

 and the second also form with one another a parallel 

 series or current that is never broken: or, to speak 

 strictly, no breakage of either is ever directly known. 

 Those of the first order cohere with one another, not 

 only longitudinally, but also transversely ; as do also- 

 those of the second order with one another. Between 

 manifestations of the first order the cohesions, both 

 longitudinal and transverse, are indissoluble; but 

 between manifestations of the second order, these 

 cohesions are most of them dissoluble with ease. 

 While the members of each series or current are so 

 coherent with one another that the current cannot be 

 broken, the two currents, running side by side as they 

 do, have but little coherence the great body of the-
