The Triviality Result is not Counter-Intuitive [PDF]

open access: yes
The Equation (TE) states that the probability of A → B is the probability of B given A. Lewis (1976) has shown that the acceptance of TE implies that the probability of A → B is the probability of B, which is implausible: the probability of a conditional

Small Steps and Great Leaps in Thought: The Epistemology of Basic Deductive Rules [PDF]

open access: yes, 2019
We are justified in employing the rule of inference Modus Ponens (or one much like it) as basic in our reasoning. By contrast, we are not justified in employing a rule of inference that permits inferring to some difficult mathematical theorem from the ...

A Partition-Based Semantics for Deontic Modals

open access: yesPrincipia: An International Journal of Epistemology
Kolodny and MacFarlane (“Ifs and oughts,” JPhil 107(3)) and MacFarlane (Assessment sensitivity, Chapter 11) describe the distinctive behavior of deontic modals in deliberation. They highlight two main features that any semantic theory should account for.

Οἱ σοφοὶ πλὴν Παρμενίδου. PER UNA RICOSTRUZIONE DELL’ARGOMENTO PLATONICO CHE DIMOSTRA LE IDEE DALLA POSSIBILITÀ DELLA CONOSCENZA

open access: yesPrometeus: Filosofia em Revista, 2018
Da un esame congiunto di alcuni passi platonici (in part. Resp. V 476e4-477b11, Crat. 439b10-440c1 e Tim. 51d-52a) e di Aristotele (Metaph. Μ 4.1078b12-17 e De cael., III 1, 298b14-24) si argomenta che Platone ha adottato una prova dell’esistenza delle ...

Correctness of Fuzzy Inference Systems Based on f-Inclusion

open access: yesMathematics
Recent work has shown that the f-index of inclusion can serve as a foundation for modeling Generalized Modus Ponens. In this paper, we develop a novel fuzzy inference system based on this inference rule.

On Boolean modus ponens

open access: yesMathware & soft computing, 1998
An abstract form of modus ponens in a Boolean algebra was suggested in [1]. In this paper we use the general theory of Boolean equations (see e.g. [2]) to obtain a further generalization. For a similar research on Boolean deduction theorems see [3].

A new probabilistic explanation of the Modus Ponens–Modus Tollens asymmetry [PDF]

open access: yes, 2019
A consistent finding in research on conditional reasoning is that individuals are more likely to endorse the valid modus ponens (MP) inference than the equally valid modus tollens (MT) inference. This pattern holds for both abstract task and probabilistic task.

Counterfactual Logic and the Necessity of Mathematics [PDF]

open access: yes
This paper is concerned with counterfactual logic and its implications for the modal status of mathematical claims. It is most directly a response to an ambitious program by Yli-Vakkuri and Hawthorne (2018), who seek to establish that mathematics is ...
