CHANGING IDENTITIES 



a change of space occupied, and, therefore, a shift- 

 ing of the common centre. 



It may seem that animals retain their centre of 

 force, yet a closer investigation proves that even 

 animals do not grow equally in all directions. 



But neither wheat stalk nor animal grows by 

 the addition of solid particles on the outside of the 

 solid particles already in place. 



Everything we see growing has on the outside an 

 envelope of more or less solid material. And some- 

 where within that solid envelope there are tubes 

 for carrying liquid substance, which in some organ 

 of the living identity are transformed into iden- 

 tical substance. 



The nails on the fingers do not grow on that end 

 we continually cut off, but they are pushed out 

 from the quick. So it seems to be with all growth. 

 But how is this done ? 



Again, let it be granted that Prop. XVII, B. 2, is 

 correct. And let it be remembered that through- 

 out all the Universe matter is continuous. (Prop. 

 I, B. 1.) 



And the shifting of primary spheres of void mat- 

 ter requires no force. 



But void matter organized into material sub- 

 stance occupies less room in the Universe than it 

 did before, and, therefore, the tremendous force 

 displayed in growth is not the result of new iden- 

 tities organizing, but of the old identities disor- 

 ganizing, and thereby requiring more room. 



For everywhere the birth of a new identity is
