Certainly for artists....

[Paul Whybrow]

Certainly for artists of all stripes, the unknown, the idea or the form or the tale that has not yet arrived, is what must be found. 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.
