THE METAPHYSICS OF SENSATION 289 



NOTE B (p. 257). 



I am afraid this paragraph is very faulty, and indeed 

 misleading. 



Scholastic " Realism " means the doctrine that generic 

 conceptions have an objective existence apart from the hu- 

 man mind. Conceptualism asserts that they exist only in 

 the mind ; nominalism, that general terms are mere names 

 indicative 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 scholas- 

 tic sense. Berkeley would reply motion and figure are purely 

 mental existences abolish all minds, and what becomes of 

 them 1 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. 275). 



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

 ommend the following experiment. Take two of the ordi- 

 nary 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 inter- 

 section of the lines prolonging the two optic axes, and ap- 

 parently, 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.
