I want to defend society and its inhabitants from all ideologies, science included.
Would you tell me what the preposition from means here?
Although I have seen and known the preposition of might mean against, in fact, my profs. has just told me :
"the preposition from in this sentence never ever means against, it means just of".
Do you know why?
Because if you want to put the preposition of, then you must put a noun of place after the word inhabitants! for example:
Inhabitants of India not inhabitants from India
And, as there is not any place, so we have to put the preposition from instead of of.
I don't find "defend from" natural there, "defend against" (as in the title of the document in the link) is much better.
