The notion that politics and economics can be neatly divided into polis and oikos — either in the sense that the markets should be entirely freed of political intervention or that political action can be effected without careful consideration of economic inputs — is ludicrous.
As I wrote previously, Pier Vittorio Aureli’s distinction between the city and urbanisation, which rests on differentiating polis and oikos, seems absurd to me, too. It’s an intensely contestable and political distinction that Aureli tries to pass off as the very ground of politics.
