46 MATHESIS. 



formless aether, when it moves itself, must be connected 

 with a phenomenon, that depends upon its expansion and 

 identification, which is polarized by light. This action 

 of the aether does not therefore depend upon the tension 

 of aether, not upon production from differences in the 

 same, but upon dissolution of the tension, therefore upon 

 extension, upon the indifferent representation of space. 

 This action, which is at the same time universal, can only 

 be heat. Moved aether is Heat. 



201. Heat is the contest of the indifferent aether with 

 light; light alone produces heat. Without light the 

 world were not only dark, but also absolutely cold. Cold 

 is untensed and quiescent aether, death, nothing ; dark 

 and cold are one. Heat is therefore the result of light, 

 but equally eternal with it ; it is space represented really, 

 as that is real time. 



202. Heat is not moved indifferent ether, which is = 

 nothing ; but moved and tensed or the moved liylit. 



203. Heat penetrates into thickness as an extending 

 function, but does not oscillate between two poles like 

 light. It is only the function of density, and depends 

 upon nothing else, not upon lines or mere surfaces, but 

 upon the living sphere. 



204. Heat and light, although characters of one sub- 

 stance, yet stand in an antagonism like thickness and line, 

 or as indifference and difference. Heat is properly the 

 first perfected position of the primary act, while light is 

 only the act of positing; the latter therefore is -f, the 

 former . Or also, gravity is the absolute position, 

 simply = ; light is the commencing egression of this 

 position out of itself -\ , heat the completion + , and 

 therefore the position everywhere ; it will everywhere 

 deposit, therefore it is motion, repletion of space, expan- 

 sion. Light is gravity become real, or become real ; 



however, rendered real, is ^ . Heat is as at the 



same time + and 0, or light and gravity, material 

 light, light that is filling. Both will also assert the 

 antagonism of their genesis through all forms of the
