“Zeus had changed into Eros when about to create,” writes the early Greek thinker Pherecydes, and, “having composed the world from the opposites, he led it into agreement and peace and sowed sameness in all things, and unity that interpenetrates the universe.”

“It is an arresting image, Lord, Zeus changing into Eros in order to bring opposites into a unity.  Was Pherecydes inspired?”

No, he was not inspired.  The particular passage is insightful, however.  It reflects the dynamic in the universe, in being, the dialectic of otherness and sameness.  There is sameness in all things and I put it there.  It is equivalent to order.  Otherwise things would fall apart.  A similar image is centripetal and centrifugal—there need to be forces of attraction and forces of repulsion.

“I understand that, if the gravitational pull were just slightly stronger, all the galaxies would collapse into a single lump.  And, if it were the slightest bit weaker, nothing would hold together.  Lord, could gravity, if this makes sense, be a kind of love or an expression of love?”

Yes, love exists at all levels, just as spirit or soul exists at all levels.  At the physical level, it is things like gravity.  At the level of human personality, it is integrity; it is the “transcendental unity of apperception” for consciousness (personality).  It is institutions and mores for society, balance and harmony for art, and so forth.
