Question: In contemporary times, HaShem's hashgacha over everything is a common hashkafah, at least in the Litvish/Chassidic communities (see Baal Shem Tov, Aruch HaShulchan, Rav Dessler 'Strive for Truth', Ramchal 'Daas vTevunos', etc.).

This of course is in contrast to the Rambam and the Ramban, who hold Aristotlean influenced views (or so i've heard), and for sure at least SEEMINGLY (i've seen them mitaretzed) opposing views. 

This question is not to compare/contrast the view points or to explain either of them, but rather to provide any information about other Rishonim that may have held views akin to the Baal Shem Tov etc. 

Note: I (think I) remember seeing that Rabbeinu Yonah did in fact hold like the Baal Shem Tov, but I can't remember what I saw or where I saw it.

Also, anything from the Zohar would also interest me.

Answer: 
"The Ari says that while many rishonim were wrong
on kabbalistic ideas the Ramban wa= s always right. R. Zadok says this
proves that the Ran erred. He firther states that once the Zohar was
revealed one is prohibited from accepting the Rambam and others who held
that hasgacha does not apply to every individual and especially not to
every animal. Rather one is required to reject this opinion as apikorsus."

**If someone could source this comment from the AriZaL, that would be much appreciated**
[Zohar Shelach 3:157b](http://www.toratemetfreeware.com/online/f_01150_part_4.html#HtmpReportNum0001_L2), while explaining Koheles seems to state the hashkafa as the Chassidim
