as in the ear, when hearing, the crystalline forms of the 

 air are delineated. 



2925. The eye does not on that account see two 

 worlds. For the chromatic image is nothing else than 

 that which is external to or without the eye. It is 

 verily one and the same influence of light, which acts con- 

 tinuously in a straight line between the chromatic 

 image and the object apparent or beheld. 



2926. As a stick thrusts us from the side whither it 

 conies ; so does the chromatic image from the side 

 whence the light comes. The exit and entrance of the 

 light are not distinct from each other. The objects 

 could not therefore appear reversed, because we do not 

 see the image in the eye, but feel its process of deoxy- 

 dation along with its direction. 



2927. The objects of the eye are colours. Like as 

 they are related in nature, so also must they be in sight ; 

 for they are only the eye extended, or this again is only 

 the formed colour. 



2928. We see nothing else but colours, no bodies. For 

 the eye there is no material world. It directly perceives 

 the spirit, and indeed its own spirit, or the world of 

 light. 



2929. There is no pre-established harmony, but com- 

 plete conformity between the world and organ of sense.

1. Of the Sexual Intestine. 



2930. As the sexual animal is in every respect the en- 

 cephalic animal reversed, so also is this the case in respect 

 to its functions. The sexual intestine gives out through 

 its mouth or anus, while the other or animal gut takes in.
