manifestations. Similarly with the antecedents to the vivid 

 manifestations which we distinguish as those of touch and 

 pressure. All the changeable ones have for their conditions 

 of occurrence certain vivid manifestations which we know 

 as sensations of muscular tension. It is true that the condi- 

 tions to these conditions are manifestations of the faint order 

 those ideas of muscular actions which precede muscular 

 actions. And we are here introduced to a complication 

 arising from the fact that what is called the body, is present 

 to us as a set of vivid manifestations connected with the 

 faint manifestations in a special way a way such that in 

 it alone certain vivid manifestations are capable of being 

 produced by faint manifestations. There must be named, 

 too, the kindred exception furnished by the emotions 

 an exception which, however, serves to enforce the gen- 

 eral proposition. For while it is true that the emotions are 

 to be considered as a certain kind of vivid manifestations, 

 and are yet capable of being produced by the faint mani- 

 festations we call ideas; it is also true that because the 

 conditions to their occurrence thus exist among the faint 

 manifestations, we class them as belonging to the same gen- 

 eral aggregate as the faint manifestations do not class 

 them with such other vivid manifestations as colours, 

 sounds, pressures, smells, &c. But omitting these peculiar 

 vivid manifestations which we know as muscular tensions 

 and emotions, and which we habitually class apart, we may 

 say of all the rest, that the conditions to their existence as 

 vivid manifestations are manifestations belonging to their 

 own class. In the parallel current we find a paral- 



lel truth. Though many manifestations of the faint order 

 are partly caused by manifestations of the vivid order, 

 which call up memories as we say, and suggest inferences; 

 yet these results mainly depend on certain antecedents be- 

 longing to the faint order. A cloud drifts across the sun, 

 and may or may not produce an effect on the current of 

 ideas: the inference that it is about to rain may arise, or
