14 THE DOCTRINE OF DESCENT.

 are moral and not arbitrary, it is not contrary to nature 

 and its purpose, but in the highest sense conformable 

 to it."

 of antagonists of this description, in one particular, 

 namely, that to us the opposite to knowledge is igno- 

 rance, whereas they supplement knowledge by a so- 

 called higher knowledge, and by faith.
