Can one decide to follow for example the Rambam's more rational Hashkafic approach and than the Ramban for other Hashkafic ideas even though they clearly disagree?
I've heard that by practical Halacha one can't go round looking for 'kulas'- leniencies and effectively pick and choose the poskim he likes. I was wondering whether this extends to Hashkafa, meaning one cannot go around choosing the ideas they like from every Rishon and Acharon they find.
