A biresiduation algebra is a 〈/,\,1〉-subreduct of an integral residuated lattice. These algebras arise as algebraic models of the implicational fragment of the Full Lambek Calculus with weakening. We axiomatize the quasi-variety B of biresiduation algebras using a construction for integral residuated lattices. We define a filter of a biresiduation algebra and show that the lattice of filters is isomorphic to the lattice of B-congruences and that these lattices are distributive. We give a finite basis of terms for generating filters (...) and use this to characterize the subvarieties of B with EDPC and also the discriminator varieties. A variety generated by a finite biresiduation algebra is shown to be a subvariety of B. The lattice of subvarieties of B is investigated; we show that there are precisely three finitely generated covers of the atom. (shrink)

Examines some of the ethical questions raised by the capabilities of modern medicine.

Marcel Gauchet spoke of the “eclipse of the political” during the neo-liberal era, but with the rise of populism he is now forced to speak of a “revenge of the political”. As the eclipse was discussed in terms of a new era of individualization, understood as the culmination of the “disenchantment of the world”, one has a right to ask what is the place of individualization in the era of the political’s revenge, particularly as, in the face of Covid 19, (...) the refusal to wear masks is couched in terms of the defense of individual liberties? In what is an immanent critique of Gauchet’s claims, individualization is considered under four rubrics: abstract individualization vs. concrete socialization; the dilemmas of recognition; rejection of alterity; and the loss of the sense of the social. The paper concludes that the “revenge” should be understood as a revenge of an “anti-political” politics. (shrink)
