# Verisimilitude and belief change for nomic conjunctive theories

@article{Cevolani2012VerisimilitudeAB, title={Verisimilitude and belief change for nomic conjunctive theories}, author={G. Cevolani and R. Festa and T. Kuipers}, journal={Synthese}, year={2012}, volume={190}, pages={3307-3324} }

In this paper, we address the problem of truth approximation through theory change, asking whether revising our theories by newly acquired data leads us closer to the truth about a given domain. More particularly, we focus on “nomic conjunctive theories”, i.e., theories expressed as conjunctions of logically independent statements concerning the physical or, more generally, nomic possibilities and impossibilities of the domain under inquiry. We define both a comparative and a quantitative… Expand

The notions of truth approximation and empirical progress are formally direct generalizations of the earlier ones, however, truth approximation is now explicitly defined in terms of increasing truth-content and decreasing falsity-content of theories, whereas empirical progress is defined in Terms of lasting increased accepted and decreased rejected content in the light of increasing evidence.

An analysis of old and new debates about the truthlikeness ordering of conjunctive theories and a critical assessment of Oddie’s new defense of the average measure and Kuipers’ refined definition of truth approximation are given. Expand

A partial consequence account of truthlikeness

- Philosophy, Computer Science
- Synthese
- 2018

This work mobilize some classical work on partial entailment in defining a new measure of truthlikeness which satisfies a number of desiderata and has some interesting and surprising connections with other accounts on the market, shedding new light on current attempts of systematizing different approaches to verisimilitude.

Truth approximation, belief merging, and peer disagreement

- Mathematics, Computer Science
- Synthese
- 2014

This paper proves the intuition that scientific inquiry, and rational discussion in general, benefits from some heterogeneity in opinion and interaction among different viewpoints, and proves some formal results on how belief merging operators perform with respect to the task of truth approximation.

Nomic Truth Approximation by Empirical Progress Revisited

In my From Instrumentalism to Constructive Realism (2000) I have shown how an instrumentalist account of empirical progress can be related to nomic truth approximation. However, it was assumed that a… Expand

It is shown that Arrow’s well-known impossibility theorem is instrumental in bringing the ongoing discussion about verisimilitude to a more general level of abstraction, and that no qualitative unifying procedure of a functional form can simultaneously satisfy the requirements of Unanimity, Independence of irrelevant alternatives and Non-dictatorship at the level of sentence variables.
