Pragmatic Scientific Realism (PSR) urges us to take up the realist aim or the goal of truth although we have good reason to think that the goal can neither be attained nor approximated. While Newton-Smith thinks that pursuing what we know we cannot achieve is clearly irrational, Rescher disagrees and contends that pursuing an unreachable goal can be rational on pragmatic grounds—if in pursuing the unreachable goal one can get indirect benefits. I have blocked this attempt at providing a pragmatic (...) justification for the realist aim of PSR on precisely the same pragmatic grounds—since there is a competing alternative to PSR, and the alternative can provide whatever indirect benefits PSR can offer while being less risky than it is, prudential reasoning favours the alternative to PSR. This undermines the pragmatic case for the realist aim of science since the instrumentalist alternative does not aim at the truth. (shrink)

Most standard results on structure identification in first order theories depend upon the correctness and completeness (in the limit) of the data, which are provided to the learner. These assumption are essential for the reliability of inductive methods and for their limiting success (convergence to the truth). The paper investigates inductive inference from (possibly) incorrect and incomplete data. It is shown that such methods can be reliable not in the sense of truth approximation, but in the sense that the methods (...) converge to "empirically adequate" theories, i.e. theories, which are consistent with all data (past and future) and complete with respect to a given complexity class of L-sentences. Adequate theories of bounded complexity can be inferred uniformly and effectively by polynomial-time learning algorithms. Adequate theories of unbounded complexity can be inferred pointwise by less efficient methods. (shrink)

Over the last four decades arguments for and against the claim that creative hypothesis formation is based on Darwinian ‘blind’ variation have been put forward. This paper offers a new and systematic route through this long-lasting debate. It distinguishes between undirected, random, and unjustified variation, to prevent widespread confusions regarding the meaning of undirected variation. These misunderstandings concern Lamarckism, equiprobability, developmental constraints, and creative hypothesis formation. The paper then introduces and develops the standard critique that creative hypothesis formation is guided (...) rather than blind, integrating developments from contemporary research on creativity. On that basis, I discuss three compatibility arguments that have been used to answer the critique. These arguments do not deny guided variation but insist that an important analogy exists nonetheless. These compatibility arguments all fail, even though they do so for different reasons: trivialisation, conceptual confusion, and lack of evidence respectively. Revisiting the debate in this manner not only allows us to see where exactly a ‘Darwinian’ account of creative hypothesis formation goes wrong, but also to see that the debate is not about factual issues, but about the interpretation of these factual issues in Darwinian terms.

Popper's three?world doctrine differs significantly from an earlier position which insisted on a dualism of facts and norms. This dualism, combined with a hostility to that version of psychologism which holds that logical principles are descriptive psychological laws, initially led him to espouse the view that we are free to reject rules of inference as norms shaping our reasoning. However, in some formulations of his recently developed pluralistic epistemology, Popper appears to deny this freedom to the individual. Feyerabend has condemned (...) him for this. My critique conflicts with Feyerabend's, in that I develop an alternative view of the relationship between logic and psychology which retains the compulsive aspect of the third realm, but rejects that version of anti?psychologism which holds that truths of logic do not have normative implications for people's psychological states. More specifically, it is argued that it is logically possible, though logically impermissible, for people to be irrational: the categories of logic are inescapably evaluative and critical. (shrink)

Popper has provided a model for the scientific explanation of human actions and a metaphysical theory of man which can guide scientific research. In this paper I discuss the problems of the empirical content and nomicity of the Rationality Principle and extend the method of situational analysis to the problem of explaining beliefs. The domain of applicability of the Rationality Principle is bounded on one side by cases in which behavior is determined by processes which can not be influenced by (...) criticism and on the other side by the phenomenon of substantive creativity. However, a large part of human activity lies within its scope. (shrink)

Im Gegensatz zur verbreiteten Auffassung über die Voraussetzungen zur Ausbildung neuen Wissens entstehen wichtige Umstellungen im Denken häufig nicht durch harte Konfrontation zwischen Hypothesen bzw. Theorien. Vielmehr sind oft allmähliche Deutungsverschiebungen bei der Auffassung einer einzigen Hypothese bzw. Theorie zu beobachten. Derartige Prozesse erstrecken sich in der Regel über vergleichsweise lange Zeiträume und sind nicht wie die erstgenannten Vorgänge von eher kurzfristiger Natur. Verglichen mit dem Ausgangspunkt der jeweiligen Entwicklung tritt uns aber eine oft an ihrem Ende tiefgreifend veränderte Wissenssituation (...) entgegen. Infolge der Langsamkeit der geschilderten Entwicklungen und der damit zugleich gegebenen Gewöhnung ihrer Vertreter an die geänderte Situation sind derartige Veränderungen des Wissens selten in einem Ausmaß vom Bewußtsein der Neuheit begleitet, wie dies bei Vorgängen der zuerst geschilderten Art der Fall ist. Trotzdem können aber gerade diese Veränderungen nachhaltiger und von grundlegenderer Art sein als jene. In der Folge sollen die beiden angedeuteten Wege der Erkenntnis hinsichtlich ihres strukturellen Unterschieds klarer erfaßt werden. Unterschiedliche Annahmen über die zugrundeliegende Ontologie sind für diese beiden Arten der Wissensbildung von besonderem Interesse. Insbesondere wird sich auch zeigen, daß die bereits in der Fristfrage berührten pragmatischen Gesichtspunkte eine wichtige Rolle spielen. Die beiden in dieser Untersuchung herauspräparierten "Wege" sind Aspekte jeweils eines Erkenntnisprozesses. So sind sie nicht gegeneinander auszuspielen. Vielmehr weist jeder derartige Vorgang Charakteristika beider modellhaft erfaßten Typen auf. (shrink)

Genetic epistemology analyzes the growth of knowledge both in the individual person (genetic psychology) and in the socio-historical realm (the history of science). But what the relationship is between the history of science and genetic psychology remains unclear. The biogenetic law that ontogeny recapitulates phylogeny is inadequate as a characterization of the relation. A critical examination of Piaget's Introduction à l'Épistémologie Généntique indicates these are several examples of what I call stage laws common to both areas. Furthermore, there is at (...) least one example of a paradoxical inverse relation between the two — geometry. Both similarities and differences between the two domains require an explanation, a developmental explanation. Although such an explanation seems to be psychological in nature, it is not merely empirical but also normative (since psychology is both factual and normative according to Piaget). Hence genetic epistemology need not be reduced to psychology (narrowly conceived), but rather should be seen as being both empirical and normative and thus similar to certain types of contemporary philosophy of science.

J. P. Z. Bonilla's methodological approach to truthlikeness is evaluated critically. On a more general level, various senses in which the theory of truthlikeness could be seen as a theory concerned with methodology are distinguished, and it is argued that providing speical sciences with methodological tools is unrealistic as an aim of the theory of verisimilitude. Rather, when developing this theory, one should rest contnet with the more modest aim of conceptual analysis, or of providing explications for the relational concept (...) of being closer to the truth. In addition, some remarks will be made on the difficulties which the similarity approach to truthlikeness has in realizing this aim and which are caused by the important role that Hintikka's constituents have in it.

Abstract There are two kinds of beliefs. If the ultimate objective is wellbeing (util- ity), the generated beliefs are “practical.” If the ultimate objective is truth, the generated beliefs are “scientific.” This article defends the practical/scientific belief distinction. The proposed distinction has been ignored by standard rational choice theory—as well as by its two major critics, viz., the Tversky/Kahneman program and the Simon/ Gigerenzer program. One ramification of the proposed distinction is clear: agents who make errors with regard to scientific (...) beliefs (e.g., the conjunction fallacy) should not be taken as committing irrationality—because they are most probably engaging the other kind of maximization, the pursuit of wellbeing.

The viewpoint of Evolutionary Epistemology (EE) and of Genetic Epistemology (GE) on classical epistemological questions is strikingly different: EE starts with Evolutionary Biology, the subject of which is population's dynamics. GE, however, starts with Developmental Psychology and thus focusses the development of individuals. By EE knowledge is seen as portraying or copying process, and truth is interpreted as a product of adaptation, whereas for GE knowledge is due to a construction process in which the production of true insights is only (...) one possibility among others: Like falsity, error and deception, true knowledge goes back to a free relationship to reality. The difference between scientific and common knowledge is hard to be checked by EE, since both result ultimately from human hereditary structures. The study of how scientific knowledge emerges from everyday cognition is rather the task of GE. (shrink)

In recent years, the idea has been gaining ground that our traditional conceptions of knowledge and cognition are unduly limiting, in that they privilege what goes on inside the ‘skin and skull’ of an individual reasoner. Instead, it has been argued, knowledge and cognition need to be understood as embodied, situated, and extended. Whether these various interrelations and dependencies are ‘merely’ causal, or are in a more fundamental sense constitutive of knowledge and cognition, is as much a matter of controversy (...) as the degree to which they pose a challenge to ‘traditional’ conceptions of cognition, knowledge and the mind. In this paper we argue that when the idea of ‘extendedness’ is applied to a core concept in epistemology and the philosophy of science—namely, scientific evidence—things appear to be on a much surer footing. The evidential status of data gathered through extended processes—including its utility as justification or warrant—do not seem to be weakened by virtue of being extended, but instead are often strengthened because of it. Indeed, it is often precisely by virtue of this extendedness that scientific evidence grounds knowledge claims, which individuals may subsequently ascribe to themselves. The functional equivalence between machine-based gathering, filtering, and processing of data and human interpretation and assessment is the crucial factor in deciding whether evidence has been gathered, rather than the distinction between intra- and extracranial processes or individual and social processes. To prioritize biological processes here, and to assert the superiority of human cognitive capacities seems both arbitrary and unwarranted with respect to gathering evidence, and ultimately would lead to an unattractive skepticism about many of the methods used in science to gather evidence. In other words, conceiving of scientific evidence as ‘impersonal’ not only better captures the character of evidence-gathering in practice, but also makes sense of a large amount of evidence-gathering that ‘personal’ accounts fail to either acknowledge or accurately describe. Whilst we suggest it is likely that all internally-distributed evidence-gathering processes are merely contingently internal processes, a significant number of externally-distributed evidence-gathering processes are necessarily externally-distributed. Some evidence can only be gathered by extended epistemic agents. (shrink)

This article pulls together the disjointed complexification of security studies. Such analytical overview suggests that the perspective of “timescapes” allows for exploring the complexity that shapes meanings and practices of security and its governance. In this respect, it is the imperative to change that suggests the significance of complexity thinking to security studies—that is, it is alone in taking the discontinuities of global life seriously. Security, in this regard, is not merely about the clockwork of survival, but is redefined through (...) the cloudlike adaptive contingency of “security as resilience.” In this setting, the security governance of complexity is identified through its dancing to the timescaped rhythms of uncertainty, cognitive challenges, complex risks, and exaptation prompted by the heterogeneity of global life.

Searching for common ground in philosophy, science and theology, it seems to us that it would be reasonable to maintain the position of realistic pragmatism that Charles Sanders Peirce had called pragmaticism. In the pragmaticist manner, we typify the knowledge and select the types of knowledge that might be useful for understanding the problems that are of interest to us. We pose a question of how it would be possible to obtain practically useful information about reality, first from the perspective (...) of natural sciences, and then from that of theology; that is, to diversify the ways of knowledge and just maybe, to move toward a productive dialogue between science and religion.

Abstract Theories of induction in psychology and artificial intelligence assume that the process leads from observation and knowledge to the formulation of linguistic conjectures. This paper proposes instead that the process yields mental models of phenomena. It uses this hypothesis to distinguish between deduction, induction, and creative forms of thought. It shows how models could underlie inductions about specific matters. In the domain of linguistic conjectures, there are many possible inductive generalizations of a conjecture. In the domain of models, however, (...) generalization calls for only a single operation: the addition of information to a model. If the information to be added is inconsistent with the model, then it eliminates the model as false: this operation suffices for all generalizations in a Boolean domain. Otherwise, the information that is added may have effects equivalent (a) to the replacement of an existential quantifier by a universal quantifier, or (b) to the promotion of an existential quantifier from inside to outside the scope of a universal quantifier. The latter operation is novel, and does not seem to have been used in any linguistic theory of induction. Finally, the paper describes a set of constraints on human induction, and outlines the evidence in favor of a model theory of induction. (shrink)

Scientists routinely solve the problem of supplementing one’s store of variables with new theoretical posits that can explain the previously inexplicable. The banality of success at this task obscures a remarkable fact. Generating hypotheses that contain novel variables and accurately project over a limited amount of additional data is so difficult—the space of possibilities so vast—that succeeding through guesswork is overwhelmingly unlikely despite a very large number of attempts. And yet scientists do generate hypotheses of this sort in very few (...) tries. I argue that this poses a dilemma: either the long history of scientific success is a miracle, or there exists at least one method or algorithm for generating novel hypotheses with at least limited projectibility on the basis of what’s available to the scientist at a time, namely a set of observations, the history of past conjectures, and some prior theoretical commitments. In other words, either ordinary scientific success is miraculous or there exists a logic of discovery at the heart of actual scientific method. (shrink)

The intentions to simulate human cognition are permanently increasing. Nonetheless, our knowledge about human cognition is based on fragments of different points of view. Hence, it is necessary to examine which demands these points of view make on technologies aiming at simulating human cognition. In this paper it is argued that no technology can function beyond the cognitive abilities of its constructor. It seems that the cognitive limits and constrains of the constructor will also be implanted in the technologies. It (...) is perhaps the right time to think about what kind of future we are going to create by means of an artificial cognition built upon fragmentary, and many times confusing, premises. (shrink)

Professor Allwood (2011, ?On the foundation of the indigenous psychologies?, Social Epistemology 25 (1): 3?14) challenges indigenous psychologists by describing their definition of culture as a rather abstract and delimited entity that is too ?essentialized? and ?reified?, as well as ?somewhat old?fashioned? and ?too much influenced by early social anthropological writings? (p. 5). In this article, I make a distinction between the scientific microworld and the lifeworld and argue that it is necessary for social scientists to construct scientific microworlds of (...) theories for the sake of pushing forward the progress of any field in the social sciences. Allwood and J. W. Berry (2006, ?Origins and development of indigenous psychologies: An international analysis?, International Journal of Psychology 41 (4): 243?68) also recognized that western mainstream psychology is a kind of indigenous psychology. Therefore, theoretical construction in western psychology also implies a reification of culture. My central question is, then: why is the reification of the western culture of individualism a merit for the progress of psychology, and why the reification of non?western cultures by indigenous psychologists a mistake?

Reasons are given to justify the claim that computer simulations and computational science constitute a distinctively new set of scientific methods and that these methods introduce new issues in the philosophy of science. These issues are both epistemological and methodological in kind.

A common criticism of Hume’s famous anti-induction argument is that it is vitiated because it fails to foreclose the possibility of an authentically probabilistic justification of induction. I argue that this claim is false, and that on the contrary, the probability calculus itself, in the form of an elementary consequence that I call Hume’s Theorem, fully endorses Hume’s argument. Various objections, including the often-made claim that Hume is defeated by de Finetti’s exchangeability results, are considered and rejected.

It is argued that fundamental to Piaget's life works is a biologically based naturalism in which the living world is a nested complex of self-regulating, self-organising (constructing) adaptive systems. A structuralist-rationalist overlay on this core position is distinguished and it is shown how it may be excised without significant loss of content or insight. A new and richer conception of the nature of Piaget's genetic epistemology emerges, one which enjoys rich interrelationships with evolutionary epistemology. These are explored and it is (...) shown how a regulatory systems evolutionary epistemology may be embedded within genetic epistemology. (shrink)

An explicit philosophy and meta-philosophy of positivism, empiricism and popperianism is provided. Early popperianism is argued to be essentially a form of empiricism, the deviations from empiricism are traced. In contrast, the meta-philosophy and philosophy of an evolutionary naturalistic realism is developed and it is shown how the maximal conflict of this doctrine with all forms of empiricism at the meta-philosophical level both accounts for the form of its development at the philosophical level and its defense against attack from nonrealist (...) quarters. Following an earlier article on realism of similar theme (Synthese 26 (1974), 409) this paper then further explores the ramifications of a thoroughgoing realist position. (shrink)

We can characterise thought in two different ways. Which is preferred can have implications for important issues about reasoning and the norms that govern cognition. The first, which owes much to the picture of the mind encountered in Descartes' Meditations, observes that paradigmatic examples of thoughts and inferences are events and processes whose special characteristics stem from their being ‘mental’ occurrences. For example they are conscious or, if unconscious, they stand in some special relation to thought processes that are conscious. (...) They typically involve attitudes towards contents or propositions. In general, thoughts have a distinctive onto-logical status and this status depends upon their being mental and typically conscious. The second emphasises that thought is a kind of activity with a definite function. It involves the use of intelligence to solve problems, answer questions, make plans and so on. Thought should be studied as a kind of goal-directed activity. Those interested in the norms that govern thought should attend to the role of responsible disciplined reflection in carrying out this activity. (shrink)

From 1990 on, the London psychologist Max Velmans developed a novel approach to consciousness according to which an experience of an object is phenomenologically identical to an object as experienced. On the face of it I agree; but unlike Velmans I argue that the latter should be understood as comparable, not to a Kantian, but rather to a noematic.

Might there be extended cognition and thereby extended minds? Rightly, that possibility is being investigated at present by philosophers of mind. Should epistemologists share that spirit, by inquiring into the possibility of extended knowing and thereby of extended knowers? Indeed so, I argue. The key to this shift of emphasis will be an epistemologically improved understanding of the implications of epistemic externalism.

The paper analyzes the sacred foundations of Western institutional order, moving from an epistemological, historical and legal–aesthetic perspective. Firstly, it identifies an epistemological theory of complexity which, pursuing Hayek’s theory of complexity, Robilant’s notion of informative–normative systems, Popper’s theory of the Worlds, and Dupuy’s theory of endogenous fixed point, will conclusively lead to presenting the hypothesis of World 0 as the World of the foundation of legal thinking, the home of the sacred and the aesthetic. Secondly, it identifies the axiological (...) character of the legal aesthetic as a discipline, a topic that will be taken up in relation to the work of the French historian of canonical law and psychoanalyst Legendre, starting from the analysis of a legal/historiographical context (Corpus Iuris Civilis, Corpus Iuris Canonici, Hobbesian Leviathan, Kelsenian Grundnorm). Thirdly, following Ellul’s thought on secularization, the idea that we now live in a secularized, lay society, lacking in the sacred is revealed as a sort of illusion, the creation of a myth of modernity, only apparently rational. Finally the paper proposes as the task of legal theory the identification of the system of “nomograms” in which the normative message is organized, according to a nonreductionistic approach that forces legal theory to recognize the plurality of the iconic forms of the normative message. The “nomograms” respond to the need of extending the field of legal science to phenomena that the positivist theory of law does not consider important, but which the process of evolution of contemporary society imposes.
