" Truth must be sought with a pure and simple heart ; it is only to be found in nature, 

 and it should be communicated only to good men." 



Chateaubriand. 



" The philosopher has conferred on the moralist an obligation of surpassing weight. In 

 unveiling to him the living miracles which teem in rich exuberance around the minutest 

 atom, as well as throughout the largest masses of ever-active matter, he has placed before 

 him resistless evidence of immeasurable design." 



Babbage.
