  • Commentary on W. V. Quine's “Free Logic, Description, and Virtual Classes”

    Open AccessHugues LeblancARTICLEDialogue1997

    Since I wrote my doctoral dissertation lo! these forty-seven years ago under Professor Quine, my colleague Alain Voizard thought it fitting that I comment on the paper just delivered. The invitation flattered me, I confess, as did Professor Quine's choice of a subject: free logic, a logic of which I was one of the numerous fathers thirty-five years ago. So, it is in my capacity as a commentator that I address you now, saving for tomorrow afternoo…

  • De A et B , de leur indépendance logique, et de ce qu'ils n'ont aucun contenu factuel commun

    Open AccessPeter Roeper, Hugues LeblancARTICLEDialogue1997Referencias: 5

    The logical independence of two statements is tantamount to their probabilistic independence, the latter understood in a sense that derives from stochastic independence. And analogous logical and probabilistic senses of having the same factual content similarly coincide. These results are extended to notions of non-symmetrical independence and independence among more than two statements

  • Probability Functions

    Open AccessHugues Leblanc, Peter RoeperARTICLEPhilosophy of Science1992Referencias: 4

    This paper studies the extent to which probability functions are recursively definable. It proves, in particular, that the ( absolute ) probability of a statement A is recursively definable from a certain point on, to wit: from the ( absolute ) probabilities of certain atomic components and conjunctions of atomic components of A on, but to no further extent. And it proves that, generally, the probability of a statement A relative to a statement B…

  • Les fonctions de probabilité

    Open AccessHugues Leblanc, Peter RoeperARTICLEDialogue1992Referencias: 4

    Pensons aux divers énoncés qui peuvent être composés à partir d'un ensemble fini ou dénombrable d'énoncés atomiques à l'aide de, disons, ‘ ̃’ et ‘&’; soit A n'importe lequel de ces énoncés; et soit l'ensemble S A des composantes atomiques de A . La valeur de vérité de A dépend évidemment des valeurs de vérité de certains membres de S A (tous les membres de S A dans plusieurs cas, mais seulemént certains d'entre eux dans d'autres cas). En effet, s…

  • The Autonomy of Probability Theory (Notes on Kolmogorov, Rényi, and Popper)

    Hugues LeblancARTICLEThe British Journal for the…1989Citada por: 1Referencias: 7

    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.…

  • What Price Substitutivity? A Note on Probability Theory

    Open AccessHugues LeblancARTICLEPhilosophy of Science1981Citada por: 2Referencias: 2

    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 five constraints on Pr of the most elementary and most basic sort

  • Queries on Truth-Conditions

    Open AccessHugues LeblancARTICLEDialogue1975Referencias: 4

    Studying some familiar truth-conditions, I shall detail the role they play in elementary logic and inquire into our grounds for holding them true. I shall discharge the first of these assignments with a good deal of assurance, but the second with far less; to my mind, (1) below mirrors our use of ‘and’, (6) our use of ‘every’, (8) our use of ‘necessarily’, etc. pretty accurately, but little evidence to that effect has ever been supplied, and — di…

  • Études sur les règles d'inférence dites règles de Gentzen (II)

    Open AccessHugues LeblancARTICLEDialogue1963Referencias: 4

    Je vais traiter ici des inférences dont la validité tient au rôle qu'y jouent les cinq connecteurs « ⊃ », « ∼ », « & », « V » et « ≡ », les deux quantificateurs « ∀ » et « ∃ », et le signe d'identité « = ». Qu'on me permette de rappeler que les deux conjectures présentéd dans ma première étude se sont avéré'es justes. En premier lieu, toute règle de structure et toute règie d'élimination ou d'introduction pour « & » ou « V » qui vaut pour la logi…

  • Études sur les règles d'inférence dites règles de Gentzen

    Open AccessHugues LeblancARTICLEDialogue1962

    Cet article a pour objet d'étudier diverses règies d'inférence dites “règies de Gentzen”. Je me limiterai dans cette première partie aux inférences dont la validité tient au rôle qu'y jouent les cinq connecteurs « ⊃ », « ∼ » , « & », « ∨ », et « ≡ ». Celles dont la validité tient au rôle qu'y jouent ces cinq connecteurs, les deux quantificateurs « ∀ » et « ∃ », et le signe d'égalité ou d'identité « = », feront l'objet d'une autre étude. Quelques-…

  • Probabilities as Truth-Value Estimates

    Open AccessHugues LeblancARTICLEPhilosophy of Science1961

    The author recently claimed that Pr(P, Q), where Pr is a probability function and P and Q are two sentences of a formalized language L , qualifies as an estimate—made in the light of Q —of the truth-value of P in L. To substantiate his claim, the author establishes here that the two strategies lying at the opposite extremes of the spectrum of truth-value estimating strategies meet the first five of the six requirements (R1-R6) currently placed up…

    The author discusses Professor Darlington's recent paper “On the Confirmation of Laws.” He criticizes Professor Darlington for not writing out in full the evidence sentence in formula III of his paper, and expresses doubts as to whether Professor Darlington's solution to the problem of the confirmation of laws follows from the complete version of that formula
