An insoluble antinomy

In other words, there would be an antinomy, an insoluble antinomy, a non-dialectizable antinomy between, on the one hand, The law of unlimited hospitality (to give the new arrival all of one's home and oneself, to give him or her one's own, our own, without asking a name, or compensation, or the fulfilment of even the smallest condition), and on the other hand, the laws (in the plural), those rights and duties that are always conditioned and conditional, as they are defined by the Greco-Roman tradition and even the Judeo-Christian one, by all of law and all philosophy of law up to Kant and Hegel in particular, across the family, civil society, and the State.

This pervertibility is essential, irreducible, necessary too. The perfectibility of laws is at this cost. And therefore their historicity. And vice versa, conditionallaws would cease to be laws of hospitality if they were not guided, given inspiration, given aspiration, required, even, by the law of unconditional hospitality. These two regimes oflaw, of the law and the laws, are thus both contradictory, antinomic, and inseparable. They both imply and exclude each other, simultaneously. They incorporate one another at the moment of excluding one another, they are dissociated at the moment of enveloping one another, at the moment (simultaneity without simultaneity, instant of impossible synchrony, moment without moment) when, exhibiting themselves to each other, one to the others, the others to the other, they show they are both more and less hospitable, hospitable and inhospitable, hospitable inasmuch as inhospitable".
