Derrida has recently become more and more preoccupied with what has come
to be termed “possible-impossible aporias” – aporia was originally a
Greek term meaning puzzle, but it has come to mean something more like
an impasse or paradox. In particular, Derrida has described the
paradoxes that afflict notions like giving, hospitality, forgiving and
mourning. He argues that the condition of their possibility is also, and
at once, the condition of their impossibility. In this section, I will
attempt to reveal the shared logic upon which these aporias rely.
