4. Function of the Auditory Sense. 



In the aether resides the movement of the world. 



2849. To the motor system that only which is its 

 equal, and thus the movement of nature, can of necessity 

 become an object. The motor system represented as a 

 sense, cannot, however, perceive the borrowed or derived 

 motion, not the planetary or massive motion, but the 

 primary motion of the aether. The planetary motion is 

 related to the primary motion as the oxydation is to the 

 electrism, as chemical analysis to chemical affinity, and 

 consequently also as respiration to smelling, as digestion 

 to tasting, in short, as the material metatype to the spi- 

 ritual antetype. 



2850. The limbs are the planetary motion organized, 

 and therefore perceive only this material motion pres- 

 sure. Touch is related to the animal sense of motion, 

 as digestion is to the tasting. 



2851. Smell and taste no longer perceive the bodies 

 in the very act of decomposition, but their laws or their 

 spiritual operations ; so will the motor sense* not perceive, 

 like the sense of touch, the mass when in motion, but 

 only the motor laws of the mass. 



2852. These laws of motion are those of the primary 

 motion. This is, however, a product of the light in the 

 aether, an effect of polarity, and that indeed the first 

 polarity which was manifested in the universe. The 

 motor sense therefore perceives only a motion which has 

 originated through primary polarity. 



2853. Such motion is not relative in kind, i. e. it 

 does not affect several portions of the matter in reference 

 to some other matter ; but it affects the whole matter 

 internally, or its atoms, so that all matter may remain in 

 its place and yet every atom of it be moved. 



2854. This motion is like the motion of heat in the 

 matter. By it heat is excited. For internal motion of 

 the atoms, when aroused by polarity, so that every atom 

 enters into a state of motion against the other, is a 

 discharging of the poles, and consequently development 

 of heat.
