Tim Smith says Britain is very far from broken. In fact, he argues, its are a really good country, and if we learn to trust one another again we could be wonderful.

Pointing to the success of collaborative ventures he started, like the Eden Project and Big Lunch, he suggests we should set ourselves the goal of energy independence.

This, he says, would be as much about the symbolism as the environmentalism: a vivid demonstration that far from being a dying culture, we are in fact a vigorous one.

Four Thought is a series of talks which combine thought provoking ideas and engaging storytelling.
