Hello! I've come across the following phrase, "Nothing happens in contradiction to nature, only in contradiction to what we know of it."
It's not clear to me why "of" is used here and not "about". Isn't "of" used when we're just aware of the existence of something or someone without knowing any details, i.e. without having any real knowledge? I would expect to hear, for one, "I'll tell you what I know about nature" and not, "...what I know of nature". The latter sounds self-contradictory to me because "of" implies that all I know is that nature exists.
