Realism is Gravity

  

À hidden but powerful teleological motivation also intervenes at this point,to which  idealism unconsciously obeys, so cheating at its own game. Idealism's concern is precisely that it be not led to a certain terminus; it aims to avoid a certain final conclusion. Now if, from the very start, things and the extramental stability whereby they regulate our thought are so carefully rejected, it is because of the fact, above all else, that owing to a secret instinct that is the more imperious in that it remains unconfessed, the mind does not want in the end to be forced to come face to face with a transcendent, supreme reality, an abyss of personality before which every heart lies open and which our thought has to adore. The bastions and fortresses of idealistic philosophy thus appear to be just so many vast defence-works against divine personality. (from 'The Degrees of Knowledge' by Jacques Maritain)

  

This is important enough for Shankara to turn his mind to Vijnanavada.  Ontology is Theology and those that are bogged down in ‘Is it Theology or Philosophy’ miss being serious and remain essentially light floating away from the earth.  Realism is Gravity.
