Deleuze and Guattari's Anti-Oedipus

Every extension of capital – both geographical (imperialism) and psychological (marketing) – entails the simultaneous elimination of extant meanings and beliefs, and hence the extension of schizophrenia: “all that is solid melts into air,” as Marx put it.

we could define schizophrenia as a form of “unlimited semiosis” – in the psyche as well as throughout society – that emerges when fixed meanings and beliefs are subverted by the cash nexus under capitalism.

Capitalism fosters schizophrenia, in brief, because the quantitative calculations of the market replace meaning and belief-systems as the foundation of society.
