PKEFACE ix 



We are like figures ivhich some great demonstra- 

 tor draws upon the blackboard of Time. A problem 

 is to be solved, -without doubt ; what the problem 

 is, we, the figures, cannot know and do not need to 

 know ; all we know is that sooner or later we shall 

 be sponged off the board and other figures take our 

 places, and the demonstration go on. 



That we have served a purpose, that we have 

 positively appeared, that something has been ful- 

 filled in us — is not that enough ? To have played 

 a part with other figures, and to leave the board 

 clear for other forms that are to embody higher 

 results and more far-reaching conclusions — is not 

 that enough? 



Afbil, 1900.
