A Rational and Humane Science

 ball, and in a hundred other ways, it manages 

 somehow to convey intelligence of Command, 

 Control, Power, of Pity, Love, Sympathy, and all 

 those myriad emotions which flit through the 

 human mind an endless series a perfect encyclo-

 crously inadequate even as it would be to call 

 the Heart (the very centre of emotion and life,

 of Nature and isolating it from the rest, and then 

 describing it exhaustively as if it really were so iso- 

 lated. A thousand mechanicians will agree, as 

 I have said, in their description of a machine, 

 because in fact they will agree to view the machine 

 just in the one aspect of its particular action ; 

 but ask a thousand people to describe one and the

 trait-painters, skilled in their art, to paint portraits 

 of the same face and you know perfectly well 

 that all the likenesses will be different. And why 

 will they be different ? Simply because every face, 

 however rude, has infinite sides, infinite aspects,
