A couple of weeks back James Bradley, on his "City of Tongues" weblog, reprinted an essay he had written and had published in "The Griffith Review". The title of that essay was "On Depression and Creativity", which was reprinted, in an edited version in "The Age" Review section over the weekend [not currently on the paper's website].
And for the past couple of weeks I've wanted to link to this piece and bring it to your attention. The trouble was that every introduction I thought of came across as insignificant and trite. So I've decided not to bother with one. If you're at all intrigued by the creative process, fascinated by the ways a physical and emotive state can affect that process, and interested in what the current state of the Australian essay has to offer at its best, then I suggest you read it. If you don't, you'll be missing something.
