I have been exploring spirals as a metaphor of the boundaries between inside and outside. Gaston Bachelard described outside and inside form as a dialectic of division. What interests me are the overlaps between the two.
“But what a spiral man’s being represents! And what a number of invertible dynamisms there are in this spiral! One no longer knows right away whether one is running towards the centre or escaping.”
“And if we want to determine man’s being, we are never sure of being closer to ourselves if we ” withdraw” into ourselves, if we move toward the centre of the spiral; for often it is in the heart of being that being is errancy. Sometimes, it is in being outside itself that being tests consistencies. Sometimes too it is closed in, as it were, on the outside. Later, I shall give a poetic text in which the prison is outside.”

Repetition is a method of generating difference and of creating fluidity.
