The old exhortations to nationalist fervor and jingoist pride have begun to lose their appeal. Perhaps because of rising standards of living, children are being treated better worldwide. In only a few decades, sweeping global changes have begun to move in precisely the directions needed for human survival. A new consciousness is developing which recognizes that we are one species.

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.

We are the local embodiment of a Cosmos grown to self-awareness. We have begun to contemplate our origins: starstuff pondering the stars; organized assemblages of ten billion billion billion atoms considering the evolution of atoms; tracing the long journey by which, here at least, consciousness arose.

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.

Honest, open communication is the only street that leads us into the real world... We then begin to grow as never before. And once we are on this road, happiness cannot be far away.
