Let me put it another way: civilisations have collapsed before, but humanity survived. Two assumptions then are necessary to say that humanity is doomed. The first assumption is that "our civilisation", meaning the inter-linked global state system, is doomed. The second assumption is that the collapse of this system will destroy humanity.
the fate of different ethnic groups are much more connected today than they were before.
I blame the forgetting of Being. Also: phonologophallocentrism, obscure and reactive subjectivities, the reduction of the Face of the Other to a mere sense datum, biopower, sex negativity, vampiric capital, arborescent conceptual schematisation, grand narratives, the Spectacle and the blocking of flows.
A self-appointed vanguard, no less. Only such a vanguard can accomplish the crystallisation of the pre-tensor into a present-tensor, a scintillating vector* of pre-tension.
