Valerie - The language used is is very "high-brow", and the turn of phrase long winded using concepts which are extremely abstract to describe something rather simple.  Here is the definition of pretentious:

pretentious adj 1 pompous, self-important or foolishly grandiose. 2 phoney or affected. 3 showy; ostentatious.

And here is just one example of over-doing it (imo the whole article is but here is just one phrase)::

But it is a picture of a peculiar kind: simultaneous release from, and anchorage to, the “out there” on which it ineluctably depends, gives it its power.

I'm a native english speaker just graduated from uni (where style of writing does border on this), and i have no idea firstly what "ineluctably" means without looking it up nor really what he is getting at.  The syntax and punctuation/grammar stink of the archaic (hard to explain why on a linguistic level without writing an essay), which is all i really needed to point out to show this guy is being "foolishly grandiose" as per the definition.

In every stone sleeps a crystal.
Remember the Shaman, when he used to say:
Man is the dream of the Dolphin"
