There is a dimension of time completely left aside by physics: the becoming. Re-analyzed in modern terms, the becoming is entangled with the production of a sign and it deserves the name of `semiotic time'. The study of this dimension of time offers an angle to investigate the Mind-body problem. It reveals that the semiotic time must be discretized.
The `interpretation' of Quantum Mechanics, i.e. the understanding of the state-vector collapse in a measurement process, is one of the major scientific problem of our time. The Semiotic Interpretation of QM pushes further the Von Neumann point of view that `experience only makes statements of this type: an observer has made a certain observation; and never any like this: a physical quantity has [I add: per se] a certain value.)' (Math. Found. of QM p. 420 Princeton U. Press).
According to this view, the state-vector collapse is not a physical phenomenon, but only the production of a sign, in the sense of Semiotics (the Science of Signs; see for instance the work of C.S. Peirce). This production is impersonnal, not issued from some psychological subject; thus it does not lead to some solipsism (on the contrary, the Subject is an effect of signs).
The production of a sign always takes some time (see above). Thus the state-vector collapse cannot be instanteneous, a specific prediction of the present model.
On the one hand, Mind is not a substance of some peculiar, subtle, type. It is Ex-pression.
On the other hand, the Body is not some substantial matter. According to the above interpretation of Quantum Mechanics, the properties of the body are the result of state-vector collapses of several types, i.e. the production of signs. In fact the universe of signs is very rich: a sign can have a conceptual `value' (like in physics), or, for instance, an affective value (like in many human behaviors). In the latter case, the Semiotic Interpretation of QM gives a way to understand how a mental representation can modify the state of the body.
A formal tool: non-stratification
Some of these ideas can hardly be expressed in plain language. A formal tool, sometimes called `self-referential logic' (Fitch 1974 Elements of Combinatory Logic, Yale Univ. Press), and which I prefer to call `non-stratification' is used to describe the concepts I have developed. It makes use of the idea that an item a can be equal to formal relations R[a] of which a is an element. An account of this tool can be found in some of the papers below.
A first account of this work is published under the title `The Now, Relativity Theory and Quantum Mechanics' in the book ` Time, Now and Quantum Mechanics ' (M. Bitbol and E. Ruhnau Eds. ISBN 2-86332-152-8 Editions Frontieres, BP 33, 91192 Gif/Yvette Cedex, France).
A presentation was made at the Workshop on `Time, Physics and Psycho-analysis' (New-York, 7 December 1996) ` Time and the Mind/Body Problem: a Quantum Perspective ', published in American Imago, vol 54, p. 307, 1997.
