This paper criticises necessitarianism, the thesis that there is at least one necessary truth; and defends possibilism, the thesis that all propositions are contingent, or that anything is possible. The second section maintains that no good conventionalist account of necessity is available, while the third section criticises model theoretic necessitarianism. The fourth section sketches some recent technical work on nonclassical logic, with the aim of weakening necessitarian intuitions and strengthening possibilist intuitions. The fifth section considers several a prioristic attempts at (...) demonstrating that there is at least one necessary proposition and finds them inadequate. The final section emphasises the epistemic aspect of possibilism. (shrink)

This is a thorough study of Calvin's conception of Christian philosophy, his exposition of insights of classical philosophy, and his evaluations of classical ...

Une histoire méconnue? Celle des femmes africaines, celle de la ville coloniale, ou plutôt celle du métissage qui a présidé à la rencontre des femmes et des cultures urbaines. Une histoire que l'on ne comprend qu'en prenant la mesure du rôle phare des cultures populaires que les femmes ont investi dès que les lois coloniales leur permirent le droit de cité à Kinshasa, à l'origine un campement pour travailleurs célibataires que l'arrivée des femmes a transformé en espace social métis. Les (...) femmes ont fait la ville (coloniale), façonné de nouveaux styles de vie et permis aux citadins africains de prendre en charge, via la musique, la fête, le mouvement associatif, le petit commerce, un domaine qui avait été conçu par les autorités coloniales comme un laboratoire et un instrument de contrôle social, et aussi politique.

We study the strength (over bounded induction) of axioms expressing particular cases of the Chinese Remainder Theorem with respect to the axiom ∀ x, y∃ z (z = xy).

. We provide an alternative proof of a theorem of P. Clote concerning end extensions of models of $\Sigma_n$ -induction, for $n \geq 2$.

We study problems of Clote and Paris, concerning the existence of end extensions of models of Σ n -collection. We continue the study of the notion of ‘Γ-fullness’, begun by Wilkie and Paris (Logic, Methodology and Philosophy of Science VIII (Moscow, 1987). Stud. Logic Found. Math., vol. 126, pp. 143–161. North- Holland, Amsterdam, 1989) and introduce and study a generalization of it, to be used in connection with the existence of Σ n -elementary end extensions (instead of plain end extensions). (...) We obtain (a) alternative proofs of results (Adamowicz in Fund. Math. 136, 133–145, 1990) and (Wilkie and Paris in Logic, Methodology and Philosophy of Science VIII (Moscow, 1987). Stud. Logic Found. Math., vol. 126, pp. 143–161. North-Holland, Amsterdam, 1989) related to the problem of Paris and (b) a partial solution to the problem of Clote. (shrink)
