550 DISSOLUTION. 



co-existent forces of attraction and repulsion, which, as we 

 have seen, necessitate rhythm in all minor changes through- 

 out the Universe, also necessitate rhythm in the totality of 

 its changes — produce now an immeasurable period during 

 which the attractive forces predominating, cause universal 

 concentration, and then an immeasurable period during 

 winch the repulsive forces predominating, cause universal 

 diffusion — alternate eras of Evolution and Dissolution. 

 And thus there is suggested the conception of a past during 

 which there have been successive Evolutions analogous to 

 that which is now going on; and a future during which 

 successive other such Evolutions may go on — ever the same 

 in principle but never the same in concrete result.
