Ontology
I simply cannot parse sentences with that word in it. I know -- from observing the AI types at work -- that it more or less means making a list of words that divvy up a chunk of reality so a program can fake being intelligent through pattern-matching. And the dictionary defines it as "the branch of metaphysics that deals with the nature of being." Which, actually, thank you very much, doesn't help me much.
But what does it mean in a text translated from the Greek written in Paris of the seventies? That is, what the thingummybob is the meaning of "ontological ethos of the communion?"? The weirdest thing is, if I just scratch out all instances of the word in this book (The Freedom of Morality, Christos Yannaras), all sentences seem to make perfect sense, and I cannot conceive of a way they will have any more meaning than with their auctorial scattering of "ontological".
Same with the adjective "existential" in the same book or "real" and "true" in Schmemann's "Introduction to Liturgical Theology." If these were hack writers I'd suspect them of trying to up the wordcount a bit...
