 such principles, as are destructive of all religion. 



The fourth species of knowledge, which we have

 and things supernatural", reaches farther than their 

 existence, and that lively analogy, under which they 

 are represented ; which is as plain, and obvious, and 

 Intelligible, as any thing in common life. 



. Our reason must convince us, that the matter 

 of the information is possible, that it implies no con- 

 tradiction. And if the information relates to things 

 supernatural, this is a fundamental rule, to deduce 

 no contradiction,, but from what is plain and intelli-

 such absurdities and contradictions as arise from a 

 comparison of what is plain and intelligible, with 

 what is incomprehensible, in respect of their intrinsic 

 natures, are all groundless and imaginary.
