Abstract
The polis, as a gathering of various citizens, may be threatened by discord and finally may collapse
because of the stasis, the internal conflict between different groups of people with diverging interests.
This scheme is tackled by Plato in Gorgias, and more thoroughly in the Republic. Both dialogues
were a source of inspiration for the pseudo-Pythagorean writings which flourished between the second
half of the 4th century B.C. and the Hellenistic period. Among them, the treaties attributed to
Kleinias, Metopus, Theages, Lysis and Hippodamus frequently use the concept of stasis and
pleonexia to describe how a city may be governed and what kind of danger may appear if the citizens’
behavior is not controlled. In general, these treaties adapt the vision of Plato concerning conflict to
some Pythagorean images and teachings. By mingling both influences, they blur the frontier between
Platonism and Pythagoreanism and create a genre of intertwined literature which may be qualified
as bricolage, according to Lévi-Strauss’s concept. These philosophical texts use a range of material
mostly traced back to the Hellenistic period, but also some fragments related to the conception of
conflicts and violence in early Pythagoreanism
