'Pure' is by definition: unmixed, unadulterated but 'coincidence' (occurring or being together) blends those that occur or be together, creating other meaning, symbols or memories. As a noun it lacks the dynamic self which lies within it, while 'coincide' in its verb form appeals to me more--by introducing both time and space into the equation (huh I seem to be arguing my scientific self here, losing the spontaneity of a coincidence, that leap of thought to somewhere until then unknown).
I had set out to make a list of coincidences but instead I find it is coincidence itself which appears to be a dynamic of this project. I have Francis Ponge and Ruth to thank for this insight. A book of Ponge's selected poems sits next to me as I write and I had lifted it absent-mindedly (my mind coincidentally elsewhere concerning itself with Nick's un-wellness and need for chicken soup) and read it before I started to type out this erstwhile list.
Water's restlessness: sensitive to the slightest change of slope. Jumping downstairs both feet at a time. Playful, childishly obedient, coming right back when you call it by shifting the incline to this side (FP, Selected Poems, p59).
And a poem by Mark Tredinnick included in this year's "Best Australian Poems": for I am also marked by the moon, my vision occluded.
