    What is Wrong with Verisimilitude.Joseph Wayne Smith - 1984 - Philosophy Research Archives 10:511-541.
    Karl Popper introduced the idea of verisimilitude to explicate the intuitive idea that a theory T2, even though it is strictly speaking false, may be closer to the truth than a competitor T1. However, as is now well known, the results of Pavel Tichý, John Harris and David Miller establish that on Popper’s qualitative theory of verisimilitude, a theory T2 could be closer to the truth than another theory T1 only if T2 contains no false sentences. This result has been (...)

    The Significance of Verisimilitude.Ilkka Niiniluoto - 1984 - PSA: Proceedings of the Biennial Meeting of the Philosophy of Science Association 1984:591 - 613.
    The concept of verisimilitude is an indispensable tool for the fallibilist and realist epistemology. Part of the argument for this thesis consists in the important applications of this notion within the history and philosophy of science. But perhaps the harder part is to convince a sceptical reader of the existence of this concept. A general programme for defining and estimating degrees of truthlikeness for various kinds of scientific statements is outlined in some detail. Ten years after Miller's and Tichy's refutation (...)

    Relevance and Verisimilitude.Chris Mortensen - 1983 - Synthese 55 (3):353-364.
    Popper's definition looked initially promising provided that the restriction of classical logic was removed. As we have seen, this promise is not fulfilled. The search for a satisfactory verisimilitude ordering must therefore be pursued along more mainstream lines. The present exercise ought, however, to make us aware of the possibility that breakdowns of proposed definitions might only occur because of strictly classical assumptions.

    What Shall We Do with Verisimilitude?Ilkka Niiniluoto - 1982 - Philosophy of Science 49 (2):181-197.
    Popper distinguishes the problems of theoretical and pragmatic preference between rival theories, but he claims that there is a common non-inductive solution to both of them, viz. the "best-tested theory", or the theory with the highest degree of corroboration. He further suggests that the degrees of corroboration serve as indicators of verisimilitude. One may therefore raise the question whether the recent theory of verisimilitude gives a general non-inductive solution to the problem of theoretical preference. This paper argues that this is (...)

    Verisimilitude by Means of Short Theorems.Peter L. Mott - 1978 - Synthese 38 (2):247 - 273.
    This paper began with the simple object of finding an account that allowed us to compare incompatible false theories. This we achieved with ρ. But that relation is language — or interest — dependent. ρ' is free from this limitation; though thus liberated it is perhaps rather unconcerned about what is true, and further fails to deliver certain intuitive comparisons. Whether ρ is to be preferred to ρ' or vice versa, seems to me a largely fruitless question: In fact it (...)

    A New Theory of Content I: Basic Content. [REVIEW]Ken Gemes - 1994 - Journal of Philosophical Logic 23 (6):595 - 620.
    Philosophers of science as divergent as the inductivist Carnap and the deductivist Popper share the notion that the (logical) content of a proposition is given by its consequence class. I claim that this notion of content is (a) unintuitive and (b) inappropriate for many of the formal needs of philosophers of science. The basic problem is that given this notion of content, for any arbitrary p and q, [(p ∨ q)] will count as part of the content of both p (...)

    Verisimilitude: The Third Period.Ilkka Niiniluoto - 1998 - British Journal for the Philosophy of Science 49 (1):1-29.
    The modern history of verisimilitude can be divided into three periods. The first began in 1960, when Karl Popper proposed his qualitative definition of what it is for one theory to be more truthlike than another theory, and lasted until 1974, when David Miller and Pavel Trich published their refutation of Popper's definition. The second period started immediately with the attempt to explicate truthlikeness by means of relations of similarity or resemblance between states of affairs (or their linguistic representations); the (...)

    This paper starts by summarizing work that philosophers have done in the fields of inductive logic since 1950s and truth approximation since 1970s. It then proceeds to interpret and critically evaluate the studies on machine learning within artificial intelligence since 1980s. Parallels are drawn between identifiability results within formal learning theory and convergence results within Hintikka’s inductive logic. Another comparison is made between the PAC-learning of concepts and the notion of probable approximate truth.

THE CONCEPTS OF FALSIFIABILITY AND CORROBORATION ARE SUBMITTED TO DETAILED ANALYSIS. THE POINT OF ACCEPTING THEORIES, ACCORDING TO POPPER, IS TO OBTAIN THEORIES OF HIGH VERISIMILITUDE.

    This note aims at critically assessing a little-noticed proposal made by Popper in the second edition of "Objective Knowledge" to the effect that verisimilitude of scientific theories should be made relative to the problems they deal with. Using a simple propositional calculus formalism, it is shown that the "relativized" definition fails for the very same reason why Popper's original concept of verisimilitude collapsed -- only if one of two theories is true can they be compared in terms of the suggested (...)

    The Poverty of the Popperian Program for Truthlikeness.Graham Oddie - 1986 - Philosophy of Science 53 (2):163-178.
    The importance for realism of the concept of truthlikeness was first stressed by Popper. Popper himself not only mapped out a program for defining truthlikeness (in terms of falsity content and truth content) but produced the first definitions within this program. These were shown to be inadequate. But the program lingered on, and the most recent attempt to revive it is that of Newton-Smith. His attempt is a failure, not because of some minor defect or technical flaw in his particular (...)

    The question of truth is a broadly broached subject in Philosophy as it features along the entire historical and polemical growth of the discipline right from the time of the Ancients down to our Post-Modern era. Yet, the delimiting realization of being unable to register general success in our dogged attempts at truth and knowledge, mostly stares us blankly in the face, for matters on which philosophy endeavours to speculate on, are beyond the reach of definite knowledge.1 Our theories of (...)

    Zwart and Franssen's Impossibility Theorem Holds for Possible-World-Accounts but Not for Consequence-Accounts to Verisimilitude.Gerhard Schurz & Paul Weingartner - 2010 - Synthese 172 (3):415 - 436.
    Zwart and Franssen’s impossibility theorem reveals a conflict between the possible-world-based content-definition and the possible-world-based likeness-definition of verisimilitude. In Sect. 2 we show that the possible-world-based content-definition violates four basic intuitions of Popper’s consequence-based content-account to verisimilitude, and therefore cannot be said to be in the spirit of Popper’s account, although this is the opinion of some prominent authors. In Sect. 3 we argue that in consequence-accounts , content-aspects and likeness-aspects of verisimilitude are not in conflict with each other, but (...)

    The paper deals with two mistakes ascribed to Popper’s theory of verisimilitude. The first is the well known critique of Popper’s qualitative definition of verisimilitude produced independently by D. Miller and P. Tichý which argues that that definition is false. The second is the claim that due to Popper’s theory of verisimilitude and his theory of corroboration inductive and justificatory elements enter his theory of science. This accusation was raised e. g. by I. Lakatos and J. Watkins. The paper tries (...)

    Science progresses if we succeed in rendering the objects of scientific inquiry more comprehensively or more precisely. Popper tries to formalize this venerable idea. According to him the most comprehensive and most precise description of the world is given by the set T of all true statements. A hypothesis comes the closer to T, or has the more verisimilitude, the more true consequences and the fewer false consequences it implies. Popper proposes to order hypotheses by the inclusion relations between the (...)

Karl Popper and Thomas Kuhn, two of the most important figures in science studies in the 20th century, gave accounts of science that are in some tension with the truth view. Their central claims about science are considered here, along with two arguments that bear directly on the truth question. One argument makes an appeal to past scientific failures to argue against the truth view; (...)

Sir Karl Popper has offered two different theories of scientific progress, his theory of conjectures and refutations and corroboration, as well as his theory of verisimilitude increase. The former was attacked by some old-fashioned inductivists, yet is triumphant; the latter has been refuted by Tichy and by Miller to Popper’s own satisfaction. Oddly, however, the theory of verisimilitude was developed because of some deficiency in the theory of corroboration, and though in its present precise formulation it was (...)

    The idea of verisimilitude is implicit in the writings of Albert Einstein ever since 1905, when he declared the distribution of field energy according to Maxwell's theory an approximation to that according to quantum-radiation theory, and Newtonian kinetic energy an approximation to his relativistic mass-energy. All his life Einstein presented new ideas as yielding older established ones as special cases and first approximations. The news has reached the philosophical community via the writings of Sir Karl Popper half-a-century after Einstein's trailblazing (...)
