Context

“Consequently evil of nature is not feared if it be not apprehended as future: but if evil of nature, that is corruptive, be apprehended as near at hand, and yet with some hope of escape, then it will be feared. Reply Obj. 1: The evil of nature sometimes is not an effect of nature, as stated above. But in so far as it is an effect of nature, although it may be impossible to avoid it entirely, yet it may be possible to delay it. And with this hope one may take counsel about avoiding it. Reply Obj.” source
