The glossary of my PhD (of the same name) says this:
For Claude Lévi-Strauss a scandal occurs when a practice ordinarily governed by a set of customary rules allows itself to be contingently governed by the customary rules of another practice.
The scandal here relates to either the products or the practices enabled by the transdisciplinary move described above between what must be homologically related practices, or in this case, disciplines. A move which is characterised by the careful plotting of analogical paths through the space between the disciplines.
When the practitioner of a discipline ordinarily governed by a set of customary rules allows themself to be contingently governed by the customary rules of another discipline a transdisciplinary move occurs between the homologically related disciplines in question. This move is scandalous in Claude Lévi-Strauss’s terms and happens therefore in scandalous space. Things made in this space are described as scandalous artefacts and they are the result of an offer made between propositions.
You would probably need to read the PhD to understand what all that means. Or wait for the book…
