    The Autonomy of Probability Theory (Notes on Kolmogorov, Rényi, and Popper).Hugues Leblanc - 1989 - British Journal for the Philosophy of Science 40 (2):167-181.
    Kolmogorov's account in his [1933] of an absolute probability space presupposes given a Boolean algebra, and so does Rényi's account in his [1955] and [1964] of a relative probability space. Anxious to prove probability theory ‘autonomous’. Popper supplied in his [1955] and [1957] accounts of probability spaces of which Boolean algebras are not and [1957] accounts of probability spaces of which fields are not prerequisites but byproducts instead.1 I review the accounts in question, showing how Popper's issue from and how (...)

    Transfert d’auctoritates du sémantique à l’indiciaire au XVII e siècle : Gassendi et Hobbes.Hélène Leblanc - 2018 - Cygne Noir 6.
    L’histoire de la pensée sémiotique se caractérise par une oscillation entre définition large et définition étroite de son objet. Au Moyen Âge, la définition augustinienne du signe est jugée trop étroite, car elle ne concerne que le signe sensible. De nouvelles définitions tentent alors de faire des concepts des signes qui renvoient aux choses. L’Âge moderne, au contraire, affirme une volonté de rétrécissement à l’égard de la notion de signe. Cet article montrera les caractéristiques d’une telle réflexion sémiotique à travers (...)

    On Characterizing Unary Probability Functions and Truth-Value Functions.Hugues Leblanc - 1985 - Canadian Journal of Philosophy 15 (1):19 - 24.
    Consider a language SL having as its primitive signs one or more atomic statements, the two connectives ‘∼’ and ‘&,’ and the two parentheses ‘’; and presume the extra connectives ‘V’ and ‘≡’ defined in the customary manner. With the statements of SL substituting for sets, and the three connectives ‘∼,’ ‘&,’and ‘V’ substituting for the complementation, intersection, and union signs, the constraints that Kolmogorov places in [1] on probability functions come to read:K1. 0 ≤ P,K2. P) = 1,K3. If (...)

    What Price Substitutivity? A Note on Probability Theory.Hugues Leblanc - 1981 - Philosophy of Science 48 (2):317-322.
    Teddy Seidenfeld recently claimed that Kolmogorov's probability theory transgresses the Substitutivity Law. Underscoring the seriousness of Seidenfeld's charge, the author shows that (Popper's version of) the law, to wit: If (∀ D)(Pr(B,D)=Pr(C,D)), then Pr(A,B)=Pr(A,C), follows from just C1. 0≤ Pr(A,B)≤ 1 C2. Pr(A,A)=1 C3. Pr(A & B,C)=Pr(A,B & C)× Pr(B,C) C4. Pr(A & B,C)=Pr(B & A,C) C5. Pr(A,B & C)=Pr(A,C & B), five constraints on Pr of the most elementary and most basic sort.

    Ce mini-dossier compte parmi les résultats d’un travail de séminaire de longue haleine, développé au cours d’un cycle de trois ans, portant sur les théories philosophiques du signe de l’Antiquité à nos jours, organisé à l’UMR STL 8163 par Claudio Majolino et Laurent Cesalli. Au sein de l’arc temporel visé par ce séminaire, le XVIIe siècle avait d’emblée une place privilégiée : conçu comme un siècle de rupture qui inaugure la période moderne, il illustre surtout, en particulier dep...

    Absolute Probability Functions for Intuitionistic Propositional Logic.Peter Roeper & Hugues Leblanc - 1999 - Journal of Philosophical Logic 28 (3):223-234.
    Provided here is a characterisation of absolute probability functions for intuitionistic (propositional) logic L, i.e. a set of constraints on the unary functions P from the statements of L to the reals, which insures that (i) if a statement A of L is provable in L, then P(A) = 1 for every P, L's axiomatisation being thus sound in the probabilistic sense, and (ii) if P(A) = 1 for every P, then A is provable in L, L's axiomatisation being thus (...)

    Intention et signe dans le Tractatus de signis de Jean Poinsot.Hélène Leblanc - 2014 - Methodos 14.
    Parmi les différentes approches possibles de la matière historique, on observe souvent, dans la littérature, une tension entre les deux options suivantes : faire d’un auteur le précurseur d'une révolution dont notre modernité serait l'héritière directe, ou au contraire, et par réaction, se livrer à un travail de remise en contexte détaillé qui prend parfois le risque de gommer l'originalité possible de ce même auteur. Le Traité sur les signes de Jean Poinsot, dominicain du début du XVIIe siècle, a ainsi (...)
