Moral certainty can deafen people to any truth other than their own.

What's wrong with leading the way? We've played that role before, after all. We gave the world the secret ballot... that did so much to raise living standards and improve conditions for workers worldwide. We were a leader in extending to women the right to vote. We were barely a nation when we set the bar for bravery and sacrifice by common soldiers in foreign wars. We grew up out of racism and misogyny and homophobia to become a mostly tolerant, successful multicultural society. We did these great things because we know we are in it together. It is our core value as Australians.

While I love to read contemporary fiction, I'm not drawn to writing it. Perhaps it's because the former journalist in me is too inhibited by the press of reality; when I think about writing of my own time I always think about nonfiction narratives. Or perhaps it's just that I find the present too confounding.

I am not part of that earlier Australian generation who set off on a deliberate search for fame and fortune in distant lands. My generation was the first that didn't need to. By the 1980's when I left home, our culture had grown deep enough and wide enough to encompass all but the most rarefied of ambitions.

If there is one class of person I have never quite trusted, it is a man who knows no doubt.

And at this moment in history, our core value happens to be the raw, aching truth of the human predicament. It may also be the only belief that can save us as a species. A species that will continue to find comfort and delight in the companionship of animals, the miracle of birds, the colours of the corals and the majesty of the forests. We are in it together, on this blue spinning marble in the cold and silent void. And we must act on that belief, if we are going to be able to continue to live a good life here, in this beautiful and fragile country, on this lovely planet, our only home.

But that Franklin trip changed me profoundly. As I believe wilderness experience changes everyone. Because it puts us in our place. The human place, which our species inhabited for most of its evolutionary life. That place that shaped our psyches and made us who we are. The place where nature is big and we are small.
