From the opaque,
from the depths of the opaque I write,
reconstructing the map of a sunniness
    that is only an unverifiable postulate for the computations of the memory,
the geometrical location of the ego,
of a self which the self needs to know that it is itself,
the ego
    whose only function is that the world may continually receive news
    of the existence of the world,
    a contrivance at the service of the world for knowing if it exists.
