Ireland is such a young society. The British were the ruling class up until they left about a hundred years ago, and we've been trying to work out what our class hierarchy is ever since.

I am not good at noticing when I'm happy, except in retrospect. My gift, or fatal flaw, is for nostalgia. I have sometimes been accused of demanding perfection, of rejecting heart's desires as soon as I get close enough that the mysterious impressionistic gloss disperses into plain solid dots, but the truth is less simplistic than that. I know very well that perfection is made up of frayed, off-struck mundanities. I suppose you could say my real weakness is a kind of long-sightedness: usually it is only at a distance, and much too late, that I can see the pattern.

You don't have to like your family, you don't even have to spend time with them, to know them right down to the bone.

The smell of the sea swept over the wall and in through the empty window-hole, wide and wild with a million intoxicating secrets. I don't trust that smell. It hooks us somewhere deeper than reason or civilization, in the fragments of our cells that rocked in oceans before we had minds, and it pulls till we follow mindlessly as rutting animals....It lures us to leap off high cliffs, fling ourselves on towering waves, leaves behind everyone we love and face into thousands of miles of open water for the sake of what might be on the far shore.

Sometimes I think about the sly, flickering line that separates being spared from being rejected. Sometimes I think of the ancient gods who demanded that their sacrifices be fearless and without blemish, and I wonder whether, whoever or whatever took Peter and Jamie away, it decided I wasn't good enough.

Our entire society is based on discontent. People wanting more and more and more. Being constantly dissatisfied with their homes, their bodies, their décor, their clothes, everything – taking it for granted that that’s the whole point of life. Never to be satisfied. If you are perfectly happy with what you got, especially if what you got isn’t even all the spectacular then you’re dangerous. You’re breaking all the rules. You’re undermining the sacred economy. You’re challenging every assumption that society is built on.

I've got this theory that human beings are innately religious; we have a belief system. It doesn't have to be a theist form, necessarily. But we need a belief system, some framework on which to hang our behavior.
