In the paper we discuss criticisms against David Armstrong’s general theory of truthmaking by Gonzalo Rodriguez-Pereyra, Peter Schulte and Benjamin Schnieder, and conclude that Armstrong’s theory survives these criticisms. Special attention is given to the problems concerning Entailment Principle, Conjunction Thesis, Disjunction Thesis and to the notion of explanation.

Early twelfth-century logicians invoked past-tensed statements with future-oriented contents to undermine the assumption that every proposition ‘about the past’ is determinate. In the second half of the century, the notion of future-dependence was used to restrict the scope of necessity per accidens. At some point, this idea began to be applied in theology to solve puzzles surrounding predestination, prescience, prophecy, and faith. In the mid-1160s, Magister Udo quotes some thinkers who insisted that the principle of the necessity of the past (...) should exclude dicta that ‘relate to the future’, such as that he has been predestined. Peter of Poitiers adopted this ‘Ockhamist’ strategy around 1170. We find similar accounts in Simon of Tournai and Alan of Lille, who invoked it in other contexts as well. By the time of Praepositinus of Cremona, Hubert of Pirovano, and Stephen Langton, the restricted principle became something of a common view at Paris. (shrink)

Mariusz Grygianiec has criticized the so called "proofs of nonexistence of general objects" as based on a wrong definition. In this paper one of his arguments is shown to depend on an unsatisfiable condition (contradictory to some basic ontological intuitions) without which, however, it is inconclusive as a reductio ad absurdum. Furthermore, it is suggested that even if the argument was sound, it could by no means be counted - contrary to the Author's intention - as a counterargument to Stanisław (...) Leśniewski and Tadeusz Kotarbiński. (shrink)

This article aims to show that the so-called ‘Ockhamist’ solution to the determinist challenge was a commonplace among Parisian scholastics around 1200. On the ‘Ockhamist’ view, some propositions about the past do not fall under the necessity of the past, since their truth-value depends on the future. The paper focuses on two puzzles involving Abraham’s belief in the future Incarnation. The author discusses the ‘Ockhamist’ strategies adopted by theologians of the period, including Simon of Tournai, Peter of Poitiers, Praepositinus of (...) Cremona, Stephen Langton, Geoffrey of Poitiers, and William of Auxerre. Langton draws an analogy between Abraham’s faith and Christ’s statement “Thou shalt deny me thrice” and suggests that past movements of faith are counterfactually flexible with regard to content. In order to interpret Langton’s statements, the author sketches a model of empty slots in the supernatural layer of the past, retrospectively infused with grace. (shrink)
