In her text, The Speaking Subject, Kristeva analyzes the two Orders that constitutes the (speaking) subject en procés. Her approach to visualize her two modalities (Semiotic and Symbolic) is to call Thom’s Catastrophe Theory to help. This theory is a part of the so called bifurcation theories and supposes that “all structures are the result of the interaction of two communicating spaces; spaces, however, which do not obey the same laws.”
The Semiotic – the quasi-dimension of the Lacanian Real and Imaginary- and the Symbolic are thus the constitutives of the subject and – I believe – can be visualized by the Lorenz attractors.
These are governing us together and this dynamic construction is what co-ordinates our mental “space”.
