_ or logical science, but those of moral and meta- 
physical science.| For by science I understand 
all knowledge which rests upon evidence and 
reasoning of a like character to that which claims 
our assent to ordinary scientific propositions. And 
if any one is able to make good the assertion that 
his theology rests upon valid evidence and sound 
reasoning, then it appears to me that such theology 
will take its place as a part of science. 
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- 
ject matter of reasoning is of one kind, becomes.

virtues when the subject matter of reasoning is of 
another kind. 3
