 inwardly everywhere as the cause and 

 source of all phenomena then, indeed, 

 Mr. Spencer is making use of ideas which, 

 in more definite and more appropriate 

 language, are familiar to us all. But, 

 unfortunately, the word Energy has been 

 of late years very largely monopolised by 

 the physical sciences, in which it is used 

 to designate an ultimate and abstract 

 conception of the purely physical forces. 

 We talk of the energy of a cannon-ball, 

 of the energy of an explosive mixture, of 

 the energy of a head of water. We even 

 erect it into an abstract conception repre- 

 senting the total of Matter and of all 

 its forces, alleging that there is only a 

 definite sum of energy in the Universe
