If gold has been prized because it is the most inert element, changeless and incorruptible, water is prized for the opposite reason -- its fluidity, mobility, changeability that make it a necessity and a metaphor for life itself. To value gold over water is to value economy over ecology, that which can be locked up over that which connects all things.

It is the job of artists to open doors and invite in prophesies, the unknown, the unfamiliar; it’s where their work comes from, although its arrival signals the beginning of the long disciplined process of making it their own. Scientists too, as J. Robert Oppenheimer once remarked, ‘live always at the ‘edge of mystery’­—the boundary of the unknown.’ But they transform the unknown into the known, haul it in like fishermen; artists get you out into that dark sea.

[In mountaineering, if] we look for private experience rather than public history, even getting to the top becomes an optional narrative rather than the main point, and those who only wander in high places become part of the story.

I think that walking down the middle of the street with several thousand people who share your deepest beliefs is one of the best ways to take a walk.

A lone walker is both present and detached, more than an audience but less than a participant. Walking assuages or legitimizes this alienation.

When someone doesn't show up, the people who wait sometimes tell stories about what might have happened and come to half believe the desertion, the abduction, the accident. Worry is a way to pretend that you have knowledge or control over what you don't--and it surprises me, even in myself, how much we prefer ugly scenarios to the pure unknown. Perhaps fantasy is what you fill up maps with rather than saying that they too contain the unknown.

There is no one as dangerous as he or she who has nothing to lose.
