The central point about Lycrophron as attacked in the Politics of Aristotle, is that Lycrophron rejected the idea that the state exists to make people "just and good", instead holding the view that justice and law is about preventing people violating the bodies and goods of each other.
[1][5] This means that he treats law as a mere means, in the context of a (perhaps primitive) social contract theory, without considering it as something special, in contradistinction to, e.g., Plato but similar to both Thrasymachus and Callicles, albeit that their theories have – as far as can be ascertained from the information available about them – more specific characteristics.
[1] These 5th-century BC ideas viewed society and morality as human creations, both aiming to protect the lives and safety of the community members.
[2][7] In Rhetoric, Aristotle examines several peculiar expressions used by Lycophron, such as "the many-visaged sky of the mighty-peaked earth", "the narrow-passaged promontory", calling Xerxes "a monster of a man" and Sciron "a human destroyer".
Aristotle reports that an opponent of Lycophron and Peitholaus stated in a law-court that "These men used to sell you when they are at home, and now they have come here and bought you."
There is no context given to this phrase, though modern scholars suspect this is a reference to a case involving Lycophron I of Pherae, a tyrant.
