“…For this reason, it is surprising that it violates condition P3: that logically stronger truths are more informative, and hence more truthlike, than logically weaker truths. This principle, which Oddie (2013) calls "the value of content for truths", was defended by Popper (1963) and is typically satisfied by content-based and consequence-based accounts, like that of Schurz andWeingartner (1987, 2010). As for the similarity based approaches, it is defended by Niiniluoto (1987) and rejected by Oddie (1986Oddie ( , 2013.…”

“…In this connection, Schurz has proposed a further interesting distinction, that between conjunctive and disjunctive approaches to theory representation (Schurz and Weingartner 2010;Schurz 2011). The key idea is that the way in which propositions, or theories, are represented in the first place can have significant implications on how their relative verisimilitude is defined and assessed.…”

A partial consequence account of truthlikeness

Popper's original definition of truthlikeness relied on a central insight: that truthlikeness combines truth and information, in the sense that a proposition is closer to the truth the more true consequences and the less false consequences it entails. As intuitively compelling as this definition may be, it is untenable, as proved long ago; still, one can arguably rely on Popper's intuition to provide an adequate account of truthlikeness. To this aim, we mobilize some classical work on partial entailment in defining a new measure of truthlikeness which satisfies a number of desiderata. The resulting account has some interesting and surprising connections with other accounts on the market, thus shedding new light on current attempts of systematizing different approaches to verisimilitude.

“…5 There have been more analyses of the relationship between verisimilitude and AGM belief revision. See, in particular, the Erkenntnis september 2011 special issue on the relationship between verisimilitude and belief revision, especially Baltag and Smets ([2011]); Cevolani et al ([2011]); Kuipers ([2011]); Renardel de Lavalette and Zwart ([2011]); and Schurz ([2011]). 6 Oddie ([Forthcoming]) argues that verisimilitude theory is in conflict with a certain approach within Bayesian epistemology known as the 'accuracy framework' (Joyce ([1998]); Pettigrew ([2016]), but he does not argue that the conflict lies with the Bayesian framework itself.…”

A Verisimilitude Framework for Inductive Inference, with an Application to Phylogenetics

Bayesianism and likelihoodism are two of the most important frameworks philosophers of science use to analyse scientific methodology. However, both frameworks face a serious objection: much scientific inquiry takes place in highly idealized frameworks where all the hypotheses are known to be false. Yet, both Bayesianism and likelihoodism seem to be based on the assumption that the goal of scientific inquiry is always truth rather than closeness to the truth. Here, I argue in favor of a verisimilitude framework for inductive inference. In the verisimilitude framework, scientific inquiry is conceived of, in part, as a process where inference methods ought to be calibrated to appropriate measures of closeness to the truth. To illustrate the verisimilitude framework, I offer a reconstruction of parsimony evaluations of scientific theories, and I give a reconstruction and extended analysis of the use of parsimony inference in phylogenetics. By recasting phylogenetic inference in the verisimilitude framework, it becomes possible to both raise and address objections to phylogenetic methods that rely on parsimony. 1 Introduction 2 Problems With the Law of Likelihood 3 Introducing Verisimilitude-based Inference 4 Examples of Verisimilitude-based Inference Procedures 4.1 Parsimony inference over theories 4.2 Parsimony inference in phylogenetics 5 Conclusion

“…Schurz and Weingartner (2010) use instead conjunctive normal forms, where theories are conjunctions of content elements. Schurz (2011) observes that the "basic feature approach" developed by Roberto Festa and Gustavo Cevolani also belongs to the conjunctive camp. 18 It is restricted to c-theories or convex conjunctive theories, which are generalizations of constituents in propositional logic, i.e.…”

Truthlikeness: old and new debates

The notion of truthlikeness or verisimilitude has been a topic of intensive discussion ever since the definition proposed by Karl Popper was refuted in 1974. This paper gives an analysis of old and new debates about this notion. There is a fairly large agreement about the truthlikeness ordering of conjunctive theories, but the main rival approaches differ especially about false disjunctive theories. Continuing the debate between Niiniluoto's min-sum measure and Schurz's relevant consequence measure, the paper also gives a critical assessment of Oddie's new defense of the average measure and Kuipers' refined definition of truth approximation.
