152 THE DATA OF PHILOSOPHY. 



state known as absence of mind, this current of faint mani- 

 festations so far predominates that the vivid current scarce- 

 ly affects it at all. Hence, these concurrent series 

 of manifestations, each coherent with itself longitudinally 

 and laterally, have but a partial coherence with one an- 

 other. The vivid series is quite unmoved by its passing 

 neighbour; and though the faint series is always to some 

 extent moved by the adjacent vivid series, and is often 

 carried bodily along with the vivid series, it may never- 

 theless become in great measure separate. 



Yet another all-important differential characteristic has 

 to be specified. The conditions under which these respec- 

 tive orders of manifestations occur, are different; and the 

 conditions of occurrence of each order belong to itself. 

 Whenever the immediate antecedents of vivid manifesta- 

 tions are traceable, they prove to be other vivid mani- 

 festations; and though we cannot say that the ante- 

 cedents of the faint manifestations always lie wholly 

 among themselves, yet the essential ones lie wholly among 

 themselves. These statements will need a good deal of ex- 

 planation. Obviously, changes among any of the 

 vivid manifestations we are contemplating — the motions 

 and sounds and alterations of appearance, in what we call 

 surrounding objects — are either changes that follow certain 

 vivid manifestations, or changes of which the antecedents 

 are unapparent. Some of the vivid manifestations, how- 

 ever, occur only under certain conditions that seem to be of 

 another order. Those which we know as colours and visi- 

 ble forms presuppose open eyes. But what is the opening 

 of the eyes, translated into the terms we are here using? 

 Literally it is an occurrence of certain vivid manifestations. 

 The preliminary idea of opening the eyes does, indeed, con- 

 sist of faint manifestations, but the act of opening them 

 consists of vivid manifestations. And the like is still more 

 conspicuously the case with those movements of the eyes 

 and the head which are followed by new groups of vivid
