Berlin seems like a place of healing to me though: you have both the Holocaust Memorial and Hiroshima Strasse side-by-side there. You have the whole last century libraried and you can see exactly what we did. Now there's lots of artists and musicians moving there because they can't afford the rent in London and New York, and they're having children and making it a gentle place. It seems to be a place of hope now.

Obviously my own work comes from a conceptual art tradition, but I love the graffiti artists, and I feel spiritually closer to them than to most contemporary art; they make the city a free space of diverse voices and we shouldn't get all cynical about them just because Banksy made some money. I collaborate sometimes with Krae, who is an old school east London graffiti writer.

And now, Though haply mellow'd by correcting time, I thank thee, Heaven! that the bereaving world Hath not diminish'd the subliming hopes Of youth, in manhood's more imposing cares.

Beneath our feet a fairy pathway flows, The grass still glitters in the summer breeze, The dusky wood, and distant copse appear, And that lone stream, upon whose chequer’d face We mused, when noon-rays made the pebbles gleam, Is mirror’d to the mind: though all around Be rattling hoofs and roaring wheels, the eye Is wand’ring where the heart delights to dwell.

If you are lucky enough to be a success, by all means enjoy the applause and the adulation of the public. But never, never believe it.

Earth, air, and ocean, glorious three.

As o'er the stormy sea of human Life We sail, until our anchor'd spirits rest In the far haven of Eternity.
