THE METAPHYSICS OF SENSATION 287 



NOTE B (p. 255). 



I am afraid this paragraph is very faulty, and indeed mis- 

 leading. 



Scholastic "Realism" means the doctrine that generic con- 

 ceptions have an objective existence apart from the human 

 mind. Conceptualism asserts that they exist only in the 

 mind; nominalism, that general terms are mere names in- 

 dicative of the similarities of objective existences. 



Locke's assertion that " motion and figure are really in the 

 manna " is essentially a piece of realism in the scholastic sense. 

 Berkeley would reply motion and figure are purely mental 

 existences abolish all minds, and what becomes of them ? But 

 that does not make him into a conceptualist, still less into a 

 nominalist ; and though he may have reached his ultimate 

 position through conceptualism, his position is quite different. 



Berkeley differs from all his predecessors in affirming that the 

 only substantial existence is the hypothetical substratum of 

 mind or "spirit"; and that the whole phenomenal world 

 consists of nothing more than affections of human (and other ?) 

 spirits by the divine spirit. Pushed to its logical extreme, his 

 system passes into pantheism pure and simple. 



NOTE C (p. 273). 



To any one who possesses the faculty of squinting I recom- 

 mend the following experiment. Take two of the ordinary 

 figures of a cube, drawn for the stereoscope, and place them some 

 few inches apart on a screen or wall, the proper right hand 

 figure being on the left and the proper left on the right ; then 

 squint so as to see the left hand figure with the right eye and 

 the right with the left eye. After a little practice, there will 

 suddenly appear, at the point of intersection of the lines prolong- 

 ing the two optic axes, and apparently, suspended in the air, a 

 figure of a cube. And this image of the cube is so real that a 

 pencil held in the hand can be moved all round it, or driven 

 through it.
