1 8 DARWINIANISM. 



thickness. Nevertheless that dimensionless line is but 

 an immeasurable gulf. And in this we may seem to 

 have raised up an insuperable barrier to our own selves. 

 We say between the extremes of cause and effect, there 

 is always a middle term of embrace ; yet here, where 

 psychology and physiology, inner and outer, are con- 

 cerned, we seem to say, in exact contradiction of our own v 

 selves, that middle term there is none. And we admit 

 that the state of the case must not only seem, but 

 actually be so unless we can find the one, ultimate middle 

 term that explains all, and is the single primiplc of t\e 

 universe ! But that is an interest for a special else- 

 where. "We can say now this, however, that no scalpel 

 to ear or eye or brain will do more than simply 

 complicate the physical side : it will never reach the 

 bridge it will only lengthen the way to it. 



All that we wish now is that it should be seen what 

 Brown's invariableness amounts to. It is no solution of 

 the problem : it is, in fact and in truth, the very crux of 

 the problem itself. Why is there the invariableness 

 say of nerve (lamp) here, and of consciousness (Djin) 

 there ? The invariableness it is that is the special diffi- 

 culty. How do you account for it ? What is your 

 explanation of it ? Were we to deal with you in your 

 own way, indeed, we should ask, How do you even know 

 the invariableness ? You can, and you do, only refer 

 this invariableness to experience ; but no experience is 

 exhaustive no mere experience is adequate to a must. 

 Make experiences as numerous as you may, they are still 

 but experiences facts found simply as facts, not combina- 

 tions reasoned into necessities of insight. The separate 

 facts that have been, if they are no more than facts, bring 

 with them no certainty that they will be. Even an always 

 in the past, if no more than such always, is no guarantee 

 for an always in the future. That stands to reason ; and
