Unfortunately this mechanically simple way of conceptualizing temporality underlie much of what we consider as modern thoughts. Marxism, in its classical version, is not an exception. I wish Amin was more sensitive to the multiple ways in which time and space overlap, co-presence of diverse social times within the same spatial formation being one of them. A radical re-membering is not sheer nostalgia, it is an important theoretical praxis. As Horkheimer once said- reification is forgetting.
Past is too crucial a terrain to leave it to the religious fundamentalists.
I am not necessarily making an anti-scientific statement here. Radical politics needs to attribute some form pragmatic centrality to science. But it is only through a constant interplay between science and non-science through which radicalism of our time can overcome its modernist grounding. If the radical imaginary of communism contains a free interplay of labor and pleasure, it also needs to embody interfaces of science, myth, imagination, poetry, fantasy, magic and so on. I am all for universalism.
