THE METAPHYSICS OF SENSATION 283 



Indeed, Berkeley himself makes Philonous wind 

 up his discussions with Hylas, in a couple of 

 sentences 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. "
