The line in the mind.
A body in which gravity plays a dominant role cannot be rigid.
To make flat / flexible / instable pieces is to retain / attain a high degree of unfinishedness.
(It is possible to distinguish between a line which is perceived by the mind purely as a carrier of thought / of information (diagrammatic), and a line which is perceived as a purely visual experience.
Or: in how far can the perception of a line be a purely visual experience?
Can different 'sculptures' do only one or the other?
How can lines, identical in essence, produce this difference / evoke different responses?
What role do angles, direction, or singularities play?
Whenever two lines meet at a right angle information is added, something extra that changes the nature of the line and shifts the perception from the visual to the 'conceptual' and 'diagrammatic'.
In a shape without edges, angles, 'singularities' etc. the nature of the paradox revealed is more subtle and fundamental - the paradox comes as if from the inside of the line.)
