of a force through the affections of ordhmry matter. We believe 

 tliat every thought ami every feeling has its definite meclianical 

 correlation — that it is accompanied by a certain separation and 

 re-marshalling of the atoms of the brain. This latter process is 

 purely physical ; and were the faculties we now possess sufficiently 

 strengthened, without the creation of any new faculty, it would, 

 doubtless, be within the range of our augmented powers, to infer 

 from the molecular state of the brain the cliaracter of the thought 

 acting on it, and conversely to infer from the thought the exact 

 molecular condition of the brain. 



Herbert Spencer says that " with our present knowl- 

 edge we are in this predicament. We can think of 

 matter only in terms of mind. We can think of mind 

 only in terms of matter. When we have pushed our 

 explorations of the first to the uttermost limits, we are 

 referred to tlie second for a final answer ; and when we 

 have got a final answer of the second, we are referred 

 back to the first for an interpretation of it" (Principles 

 of Psychology, p. 272). 



Huxley says: 



For, after all, what do we know of this terrible " matter," except 

 as a name for the unknown and hypothetical cause of states of our 

 own consciousness? And what do we know of that " spirit," over 

 whose threatened extinction by matter a great lamentation is 

 arising, like that which was hoard at the death of Pan, except that 

 it is also a name for an unknown and hypothetical cause or condi- 

 tion of states of consciousness ? In other words, matter and spirit 

 are but names for the imaginary substrata of groups of natural 

 phenomena. (I^-ay Sermons). 



This definition is doubtless correct, and " a state of 

 consciousness " wliicli exists, and vvdiicli tells me that 

 there is within me a power, at command now or in the 

 future, and that through this residuary mni'dhliKj my 

 arm is raised, my head nods, my eye winks, or my 

 imagination takes flights, at any time this something 

 dictates, is entitled to ask for consideration as an entity 

 as much as, for example, pain, which is only a state of
