THE LATEST STAGE 285 



It is impossible to say which is the man or the thought. 

 The different aspects are on different planes, incom- 

 mensurable. A thought is represented by physical 

 and physiological changes, but it is none the less a 

 psychological phenomenon, part of the consciousness 

 of the man and part of his spiritual life. 



If, in the distant future, science should approach 

 towards a complete explanation of a man regarded 

 from without, expressed in electrical, mechanical or 

 aethereal terms, it would be within sight of unity in 

 the scientific domain of that unity which has been 

 the dream of so many philosophers and men of 

 science. Yet, inwardly, the consciousness of that 

 man would to himself remain an unconquered citadel, 

 a kingdom of heaven within him. 



Without necessarily holding the view of Kant and 

 his modern followers that the Ego prescribes its own 

 laws to nature, and sees its own reason reflected in 

 natural phenomena, it is clear that the particular 

 scheme of theories in which modern science is ex- 

 pressed must be regarded as conditional on, and 

 indeed originated by, the constitution and peculiar- 

 ities of our minds. As we have said when dealing 

 with the history of these conceptions, the feeling that 

 an explanation is more satisfying and fundamental 

 when expressed in mechanical terms is probably a 

 consequence of the fact that our minds and bodies 

 possess a definite muscular sense, so that for us force 

 is a direct sense-perception. Did we, like the fish- 

 torpedo, possess a special electric sense, we might 

 regard electric conceptions as equally or more funda- 

 mental and satisfying than mechanics. Moreover,
