The present antagonism between theology and 

 science does not arise from any assumption by the 

 men of science that all theology must necessarily 

 be excluded from science, but simply because 

 they are unable to allow that reason and morality 

 have two weights and two measures ; and that the 

 belief in a proposition, because authority tells you 

 it is true, or because you wish to believe it, which 

 is a high crime and misdemeanour when the sub-
