And one of my firmest conclusions is that we always think by seeking and drawing parallels to things we know from our past, and that we therefore communicate best when we exploit examples, analogies, and metaphors galore, when we avoid abstract generalities, when we use very down-to-earth, concrete, and simple language, and when we talk directly about our own experience.

One by one, they guessed aloud about what Lotto had meant by this sculpture: nautilus, fiddlehead, galaxy. Thread running off its spindle. Forces of nature, perfect in beauty, perfectly ephemeral, they guessed. He was too shy to say time. He__ woken with a dry tongue and the urge to make the abstract concrete, to build his new understanding: that this was the way that time was, a spiral.He loved the uselessness of all the effort, the ephemerality of the work. The ocean encroached, it licked their feet. It pushed around the outside wall of the spiral, fingering its way in. When the water had scooped the sand from the lifeguard's chair, revealing white like bone beneath, something broke, and the fragments spun into the future. This day would bend back and shine itself into everything.

Straight lines go too quickly to appreciate the pleasures of the journey. They rush straight to their target and then die in the very moment of their triumph without having thought, loved, suffered or enjoyed themselves. Broken lines do not know what they want. With their caprices they cut time up, abuse routes, slash the joyous flowers and split the peaceful fruits with their corners. It is another story with curved lines. The song of the curved line is called happiness.

Writers begin with a grain of sand, and then create a beach.

Our business is communication oftentimes through the medium of stories but our capacity has a far greater scope - to entertain certainly, but also to stimulate debate, to mark up changes and differences and that way, to maybe, just now and then, to change the world.

The new contract between writers and readers is one I'm prepared to sign up to. I've met some fascinating people at events and online. Down with the isolation of writers I say! And long live Twitter.
