It's not a problem of "life", "rights", "representation". These ontic objects are deeply flawed, as can be seen in the present state of the political. Even taking it in ridicule: what is one to do, fight for the right to representation of every paramecium and amoeba?

It's more about seating the political in a realm of the inconsolable (fundamentally every political decision is the bad one), uprooting the current games of bad faith and energy poverty which have constituted the political since the first gathering of hominids. The inconsolable, which at the limit is death itself (of a self, of a society, of a territory, of a universe), is binded to an ever greater cone of care, at the same time bringing closer the post-human and the post-human increasing the cone of care. The lesser-known, brilliant nonetheless, thinker Vladimir Jankélévitch [1] has some more thoughts along these lines in 1971, L 'Imprescriptible and 1974, L'Irréversible et la nostalgie.
