192 DUALISM OF FORCES. 



The expansions and emanations from centers perpetually 

 prevalent throughout the whole domain of forms and organ- 

 isms, may b'e considered as one general diastole ; while the 

 contractions and precipitations upon centers, likewise univer- 

 sally prevalent, may be considered as one general systole ; 

 and these motions, in their more progressed and periodically 

 alternating forms, are expressed in the secular expansions and 

 contractions of planetary orbits ; in the oscillations of hea- 

 venly bodies between their aphelion and perihelion points ; in 

 the ebbing and flowing of tides ; in the inspirations and ex- 

 pirations of plants ; in the dilations and contractions of the 

 human heart; and in the breathings and 'pulsations of 

 microscopic forms of life, which spoit in a single drop of 

 water. 



In attributing thus much to the laws of Expansion and 

 Contraction (or Attraction), it is not by any means intended 

 to supersede the septinary divisions of laws, as presented in 

 preceding pages. Our object has rather been to show that 

 these two fundamental laws, being, as it were, male and fe- 

 male in conjugal unity, are the parents and grandparents of 

 all other laws. Thus it is from a combination of Expansive 

 and Contractive movements that the law of Circulation im- 

 mediately ensues in every portion of the creation, even as the 

 same ensues in the animal and human systems, from the ex- 

 pansive and contractile motions of the heart : and as particles 

 are thus made to flow throughout each system, and are placed 

 in general intercommunication with other particles, there is 

 occasion given to the operation of the fourth law, by which 

 mutually affinitized particles, whether in organic or inorganic 

 creations, unite together and form the tissues of the perma- 

 nent physical structure. Thence, after performing their ap- 

 propriate offices, and undergoing specific refinements, they are
