This paper draws on the philosophy of Karl Popper to present a descriptive evolutionary epistemology that offers philosophical solutions to the following related problems: ‘What happens when learning takes place?’ and ‘What happens in human learning?’ It provides a detailed analysis of how learning takes place without any direct transfer of information from the environment to the learner, and it significantly extends the author's earlier published work on this topic. She proposes that learning should be construed as a special case (...) of ‘problem solving’ and as a fundamentally critical and creative process in which learning organisms develop ‘expectations’ that are not purely an outcome of genetic inheritance or random mutation. Human learning is then characterised with reference to: objectified knowledge; descriptive and argumentative language; theoretical problems; the search for error and specific limitation. If the author's evolutionary analysis of learning is valid, it would suggest that we should, if we wish to promote learning, be wary of corralling children and older students in environments that inhibit autonomous activity, that discourage criticality and creativity and generally limit opportunities for trial and error‐elimination. But education institutions, particularly those for older children and adolescents, are very often environments of this constraining kind. Traditionally, educationists have vastly underestimated the human potential for imaginative criticism—because in general they have not recognised the extent to which it lies at the heart of what humans, including the youngest children, do in order to succeed at even the most basic tasks.

Even though social engineering has gained a bad reputation, due to new possibilities in the information age, it may be time to reconsider Karl Popper’s conception of “piecemeal social engineering.” Piecemeal social engineering is not only an element within Popper’s open society. It also connects his political philosophy to his philosophy of science and his evolutionary epistemology. Furthermore, it seems to fit well into the search for implementation strategies for policies and social actions in the context of nonideal theory. Nevertheless, (...) this does not necessarily undermine the need for political ideals and first-order principles, which are inhabitants of “World 3.”. (shrink)

The contrast between the past-future symmetry of mechanical theories and the time-arrow observed in the behaviour of real complex systems doesn’t have nowadays a fully satisfactory explanation. If one confides in the Laplace-dream that everything be exactly and completely describable by the known mechanical differential equations, the whole experimental evidence of the irreversibility of real complex processes can only be interpreted as an illusion due to the limits of human brain and shortness of human history. In this work it is (...) surmised that in the description of real events it would be more reasonable to renounce exactness and completeness of mechanical differential equations, assuming that also further effects exist in nature, governed by different kinds of rules, in spite of being so weak to be directly unobservable in single motions. This surmise can explain not only the time-arrow, but also why, in particular cases, it can happen that approximate and/or statistical models represent an improvement of mechanical theories instead of an approximation: this happened for Boltzmann gas-model and also for the famous work of Max Planck on blackbody-radiation. And it also appears as a more promising “working hypothesis”, stimulating and guiding us to learn more about limits and origin of the basic equations, and also about the nature of chance and the meaning of probability, which is nowadays not clear in spite of the fundamental role it plays in physics. Particularly that kind of probability which gives the connection between quantum–mechanical differential equations and observable events. (shrink)

Humans appear to follow normative rules of inductive reasoning in "premise diversity tasks" that is, they know that dissimilar rather than similar evidence is better for generalising hypotheses. In three experiments, we use a "hypothesis limitation task" to compare a related inductive reasoning skill knowing how to limit hypotheses by using a negative test strategy. Participants are told that one category member has some property (e.g. Dogs have a merocrine gland) and are asked what evidence they would test to ensure (...) that either all (generalisation) or only (limitation) category members have that property (e.g. All/Only mammals have merocrine glands; tests: wolf, bull, crocodile). Despite participants' reluctance to use negative tests in the Wason 2-4-6 task and other reasoning tasks, participants do use normatively correct negative tests in the hypothesis limitation task as often as they use diverse positive tests in the premise diversity task. Moreover, when given a hypothesis limitation task before a rule evaluation task (similar to the 2-4-6 task), the use of negative tests increases. Thus, when testing hypotheses, people can and do use the right kind of test strategy for the task. (shrink)

We present a meta-analytic review on the processing of negations in conditional reasoning about affirmation problems (Modus Ponens: “MP”, Affirmation of the Consequent “AC”) and denial problems (Denial of the Antecedent “DA”, and Modus Tollens “MT”). Findings correct previous generalisations about the phenomena. First, the effects of negation in the part of the conditional about which an inference is made, are not constrained to denial problems. These inferential-negation effects are also observed on AC. Second, there generally are reliable effects of (...) a negation in the clause referred to by the categorical premise, and these referred-negation effects are constrained to the logically fallacious AC and DA inferences. All findings are presented and discussed in relation to contemporary mental model (MM) and mental logic (ML) theories. It is argued that a double-negation elimination hypothesis provides a sufficient explanation of inferential-negation effects within both MM theory and ML theory, if the latter is extended by a validating search for counter examples. Both MM and ML theories adhere to a processing scheme that allows them to incorporate an account of referred-negation effects based on the thesis that counter-example frequency is modulated by the scope of a contrast class delineated by a false affirmative. We conclude that MM and ML theories provide adequate processing schemes to accommodate for the explanatory hypotheses, at least in principle. In practice, both approaches remain equivocal as regards the connectivity and interactivity with long-term memory knowledge invoked in generating, manipulating, and testing the mental representations of negative state of affairs.

The inductive category formation framework, an influential set of theories of learning in psychology and artificial intelligence, is deeply flawed. In this framework a set of necessary and sufficient features is taken to define a category. Such definitions are not functionally justified, are not used by people, and are not inducible by a learning system. Inductive theories depend on having access to all and only relevant features, which is not only impossible but begs a key question in learning. The crucial (...) roles of other cognitive processes (such as explanation and credit assignment) are ignored or oversimplified. Learning necessarily involves pragmatic considerations that can only be handled by complex cognitive processes.We provide an alternative framework for learning according to which category definitions must be based on category function. The learning system invokes other cognitive processes to accomplish difficult tasks, makes inferences, analyses and decides among potential features, and specifies how and when categories are to be generated and modified. We also examine the methodological underpinnings of the two approaches and compare their motivations. (shrink)

According to Hume, no knowledge attainable by human beings would ever justify rational belief in recurrent physical properties and causal effects. He arrived at this conclusion because he denied the possibility of knowing--but not the reality of--either the 'inner natures' or the 'secret powers' of objects which would enable one to intuit or to demonstrate a 'necessary connection' between the internal structures of objects and their observable properties, or between the causal powers of entities and their effects. The purpose of (...) this article is to show that while Hume's scepticism was justifiable in his day given the generally accepted limitations then of scientific inquiry and explanations, it no longer is reasonable in light of later scientific discoveries and theories. To a degree to which no eighteenth-century philosopher or scientist could anticipate, experimental inquiry has disclosed the inherent natures of objects and the underlying causes of phenomena that attest to the interconnectedness of physical reality and thus justify, at least to some extent, our instinctive beliefs in the uniformity of nature and predictability of events.

This essay examines critically two related claims: first, that postmodernism and philosophy of science depend on each other in a manner similar to the Enlightenment and Romanticism, that is, they respond and dispute each other's claims; and second, that what underlies and emanates from both postmodernism and philosophy of science is a political perspective and commitment. These claims suggest not only the possibility of translating from one area to the other when they are critically engaged with each other but also (...) the potential for using both areas simultaneously to transform and possibly improve the human condition. By emphasizing the similarities between science/philosophy of science and postmodernism the essay explores the ways in which these two enterprises or groups of people can learn from one another and benefit from each other's insight.

Are there neurobiological reasons why we are willing to trust other people and why ‘trust’ and moral values such as ‘care’ play a quite pivotal role in our social lives and the judgements we make, including our social interactions and judgements made in the context of schooling? In pursuing this question, this paper largely agrees with claims made by Patricia Churchland in her 2011 book Braintrust. She believes that moral values are rooted in basic brain circuitry and chemistry, which have (...) been shaped over evolutionary time. However, these naturalistic claims raise important issues, including the standard philosophical objection that they fall victim to the naturalistic and/or deontic fallacies. This paper provides an overview of the neurobiology of trust and examines some of the main objections, in the belief that recognising the neurobiological substrate of care and trust can deepen our appreciation of the role these play in education.

Deviant forms of human thought may provide insight into epistemic standards, such as rationality. A comparative analysis of paranoia and reinforced dogmatism suggests that reinforced dogmatism, such as pseudo-science a-la-Popper, demonstrates a primary epistemic lack of critical rationality, that is, of testability, whereas paranoia demonstrates a lack of range of alternative statements leading secondarily to a lack of testability. This reflects the importance to both epistemology and psychiatry of epistemic standards in addition to testability, such as relevance to problems, and (...) emphasizes the distinction of the context of introduction from the contexts of discovery and of justification. Key Words: context of introduction • paranoia • reinforced dogmatism • relevance • testability. (shrink)

Este artigo tem como objetivo discutir algumas das teses centrais do físico teórico e epistemólogo John Michael Ziman relativas à dimensão social da ciência. Ziman sustenta que, para um melhor entendimento das mudanças ocorridas na prática científica contemporânea, sobretudo das consequências geradas nas últimas décadas pelo que ele denominou de "ciência pós-acadêmica", é necessária uma abordagem que inclua aspectos não somente filosóficos, mas também sociológicos e históricos. Segundo Ziman, a supervalorização, na ciência pós-acadêmica, de valores ligados a uma cultura gerencial (...) tem como consequências, a curto prazo, a alteração do éthos mertoniano e dos princípios filosóficos utilizados historicamente pelos cientistas como ideais reguladores; e, a longo prazo, a redução da capacidade cognitiva da ciência de produzir "novos mapas" da realidade. Ao analisar alguns conceitos-chave da obra de Ziman, tais como "consensibilidade", "consensualidade", "conhecimento público" e "ciência pós-acadêmica", esperamos debater a concepção de ciência desse autor, ainda pouco citado no Brasil. The main objective of this article is to discuss some of the central theses on the work of the physicist and epistemologist John Michael Ziman concerned with the social dimension of science. Ziman supports the thesis that in order to have a better understanding of the recent changes in scientific practice, especially the consequences brought by a new mode of knowledge production, in the last decades, which he names "post-academic", it is necessary a new methodological approach is necessary that includes, not only philosophical aspects, but also sociological and psychological ones. According to Ziman, one of the consequences of the overvaluation of a managerial culture in post academic science is, in the short term, the deflation of the Mertonian ethos and also of the philosophical principles which were historically shared amongst scientists as regulatory ideals; and in the long run, the major consequence of post-academic science would be the reduction of cognitive capacity of science to produce "new maps" of the world. By the analysis of some key-concepts in Ziman's work, such as "consensibility", "consensuality", "public knowledge" and "post-academic science", we aim to make the Brazilian reader acquainted with his conception of science.

A variety of different arguments have been offered for teaching ‘‘both sides’’ of the evolution/ID debate in public schools. This article reviews five of the most common types of arguments advanced by proponents of Intelligent Design and demonstrates how and why they are founded on confusion and misunderstanding. It argues on behalf of teaching evolution, and relegating discussion of ID to philosophy or history courses.

Growing public interest in the dark arts, and the fact that even some philosophers have been accused of casting spells with their own writings, suggest that philosophers should not wholly neglect the topics of spells and spell-breaking. In this paper, written in honor of an effective spell-breaker in social and leadership contexts, Fr Theodore Vitali, I set out a taxonomy of spells and ways in which some philosophers may be said to cast them in a naturalistic sense. I also examine (...) ways of breaking a spell, with reference to the will and second-person relationship. I conclude with a brief observation about the desire for intellectual completeness, the root of a disordered appeal of at least some spells to their victims, suggesting an alternative scenario for a good satisfaction of this desire.

This article presents and analyses a social-practice contextualist version of meaning holism, whose main root lies in American pragmatism. Proposing that beliefs depend on systems of language-use in social practices, which involve communities of people and worldly objects, such meaning holism effectively breaks down the Enlightenment tradition’s philosophical subject–object dualism. It also opens the human mind up for empirical research – in a ‘sociologizing’, ‘anthropologizing’ and ‘historicizing’ vein. The article discusses the implications of this approach for the human sciences, for (...) instance certain parallel developments in anthropology and archaeology. (shrink)
