Truthlikeness: old and new debates

  title={Truthlikeness: old and new debates},
  author={Ilkka Niiniluoto},
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… Expand
Probabilistic truthlikeness, content elements, and meta-inductive probability optimization
The paper starts with the distinction between conjunction-of-parts accounts and disjunction-of-possibilities accounts to truthlikeness (Sects. 1, 2). In Sect. 3, three distinctions between kinds ofExpand
Non-metric Propositional Similarity
A novel way of comparing the ‘distance’ between two pairs of propositions is proposed, which eschews metric assumptions and gives a precise account of comparative propositional similarity facts. Expand
Introduction to the special issue “Logical perspectives on science and cognition”
This special issue of Synthese is in honor of Gerhard Schurz, our good friend and colleague, who contributed to philosophy in a multitude of novel and interesting ways. The idea to do such a specialExpand
Can institutional theory be refuted, replaced or modified?
This paper aims to demonstrating that the former new institutional theory of isomorphism and decoupling cannot be extended, modified or refuted as it is a closed theory. By analyzing the structure ofExpand
Structural Correspondence Between Organizational Theories
Organizational research constitutes a differentiated, complex and fragmented field with multiple contradicting and incommensurable theories that make fundamentally different claims about the socialExpand


A partial consequence account of truthlikeness
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.

On the Truthlikeness of Generalizations
The topic of this paper is the notion of truthlikeness: Popper’s definition of verisimilitude is criticized, and an alternative approach is outlined within a simple and precise framework. Expand
Content and Likeness Definitions of Truthlikeness
Sjoerd D. Zwart’s doctoral dissertation Approach to the Truth (1998) divides theories of truthlikeness into two rival approaches. The content definitions operate with the notions of truth value andExpand
Verisimilitude and belief change for nomic conjunctive theories
This paper focuses 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. Expand

A new account of logical content is used to develop a definition of verisimilitude that is close to Popper’s original account and comparison to a similar approach by Schurz and Wiengartner show certain advantages. Expand
Verisimilitude: Why and How
When Karl Popper’s attempt to define verisimilitude or truthlikeness failed, some of his followers suggested that critical rationalists do not really need this notion. Some others took up theExpand
Verisimilitude Redefined

Are some falsehoods less false than others? Tarski's definition of truth tells us in rigorous terms what it takes for a statement to be false. Can we have an equally rigorous definition of what itExpand
Verisimilitude and Belief Change for Conjunctive Theories
Theory change is a central concern in contemporary epistemology and philosophy of science. In this paper, we investigate the relationships between two ongoing research programs providing formalExpand
Approximate Truth and Truthlikeness
Our standard logic is two-valued: every meaningful statement is regarded as being either true or false. Thus it may seem pointless or misleading to speak of degrees of truth or of partial truth.Expand

It is shown, in terms of truth and falsity content, that the analysis already applies when, in line with scientific common sense, nomic theories are merely assumed to exclude certain conceptual possibilities as nomic possibilities. Expand
