THE METAPHYSICS OF SENSATION 285 



about what lies beyond that limit. Whether 

 either mind, or matter, has a " substance " or not, 

 is a problem which we are incompetent to discuss; 

 and it is just as likely that the common notions 

 upon the subject should be correct as any others. 

 Indeed, Berkeley himself makes Philonous wind 

 up his discussions with Hylas, in a couple of sen- 

 tences which aptly express this conclusion: 



" You see, Hylas, the water of yonder fountain, how it is 

 forced upwards in a round column to a certain height, at 

 which it breaks and falls back into the basin from whence 

 it rose ; its ascent as well as its descent proceeding from the 

 same uniform law or principle of gravitation. Just so, the 

 same principles which, at first view, lead to scepticism, 

 pursued to a certain point, bring men back to common 

 sense."
