The clear liquid in our eyes is seawater and therefore…

““The clear liquid in our eyes is seawater and therefore there are fish in our eyes, seawater being the natural medium of fish. Since blue and green are the colours of the richest seawater, blue and green eyes are the fishiest. Dark eyes are somewhat less fecund and albino eyes are nearly fishless, sadly so. But the quantity of fish in an eye means nothing. A single tigerfish can be as beautiful, as powerful, as an entire school of seafaring tuna. That science has never observed ocular fish does nothing to refute my theory; on the contrary, it emphasizes the key hypothesis, which is: love is the food of eye fish and only love will bring them out. So to look closely into someone's eyes with cold, empirical interest is like the rude tap-tap of a finder on an aquarium, which only makes the fish flee. In a similar vein, when I took to looking at myself closely in mirrors during the turmoil of adolescence, the fact that I saw nothing in my eyes, not even the smallest guppy or tadpole, said something about my unhappiness and lack of faith in myself at the time. ...I no longer believe in eye fish in [i]fact[/i], but still do in metaphor. In the passion of an embrace, when breath, the win, is at its loudest and skin at its saltiest, I still nearly think that I could stop things and hear, feel, the rolling of the sea. I am still nearly convinced that, when my love and I kiss, we will be blessed with the sight of angelfish and sea-horses rising to the surface of our eyes, these fish being the surest proof of our love. In spite of everything, I sill profoundly believe that love is something oceanic.””
