Explaining phenomena is a primary goal of science. Consequently, it is unsurprising that gaining a proper understanding of the nature of explanation is an important goal of science education. In order to properly understand explanation, however, it is not enough to simply consider theories of the nature of explanation. Properly understanding explanation requires grasping the relation between explanation and understanding, as well as how explanations can lead to scientific knowledge. This article examines the nature of explanation, its relation to understanding, (...) and how explanations are used to generate scientific knowledge via inferences to the best explanation. Studying these features and applications of explanation not only provides insight into a concept that is important for science education in its own right, but also sheds light on an aspect of recent debates concerning the so-called consensus view of nature of science (NOS). Once the relation between explanation, understanding, and knowledge is clear, it becomes apparent that science is unified in important ways. Seeing this unification provides some support for thinking that there are general features of NOS of the sort proposed by the consensus view and that teaching about these general features of NOS should be a goal of science education.

The examples and concepts that Shoemaker cites are rather heterogeneous. Some distinctions need to be drawn. An optimality thesis involves not just an ordering of options, but a value judgment about them. So let us begin by distinguishing minimality from optimality. And the concept of minimality can play a variety of roles, among which I distinguish between extremum descriptions, statements hypothesizing an optimizing process, and methodological recommendations. Finally, I consider how the three categories relate to Shoemaker’s question that “Who is (...) optimizing: the scientist or nature?” . (shrink)

A comment on Paul Schoemaker's target article in Behavioral and Brain Sciences, 14 (1991), p. 205-215, "The Quest for Optimality: A Positive Heuristic of Science?" (https://doi.org/10.1017/S0140525X00066140). This comment argues that the optimizing model of decision leads to an infinite regress, once internal costs of decision (i.e., information and computation costs) are duly taken into account.

The focus of this essay is on Xenophanes’ criticism of anthropomorphic representation of the gods, famously sounding like a declaration of war against a constituent part of the Greek religion, and adopting terms and a tone that are unequalled amongst “pre-Socratic” authors for their directness and explicitness. While the main features of Xenophanes’ polemic are well known thanks to some of the most studied fragments of the pre-Socratic tradition, a different line of enquiry from the usual one is attempted by (...) considering the multi-layered background of the religious beliefs revolving around the idea that the gods have human form as outlined in the tradition of epic poetry or represented in cult statues: in the light of this consideration Xenophanes’ text can take on some new characteristics. In the second part of the article, emphasis is put on the importance of the correlation Xenophanes established between the issue of the appearance of the gods and that of the certainty of knowledge, in terms that have exerted tremendous influence on later thought, most notably on Plato in the Timaeus.

In the present work, quantum theory is founded on the framework of consciousness, in contrast to earlier suggestions that consciousness might be understood starting from quantum theory. The notion of streams of consciousness, usually restricted to conscious beings, is extended to the notion of a Universal/Global stream of conscious flow of ordered events. The streams of conscious events which we experience constitute sub-streams of the Universal stream. Our postulated ontological character of consciousness also consists of an operator which acts on (...) a state of potential consciousness to create or modify the likelihoods for later events to occur and become part of the Universal conscious flow. A generalized process of measurement-perception is introduced, where the operation of consciousness brings into existence, from a state of potentiality, the event in consciousness. This is mathematically represented by (a) an operator acting on the state of potential consciousness before an actual event arises in consciousness and (b) the reflecting of the result of this operation back onto the state of potential consciousness for comparison in order for the event to arise in consciousness. Beginning from our postulated ontology that consciousness is primary and from the most elementary conscious contents, such as perception of periodic change and motion, quantum theory follows naturally as the description of the conscious experience.

This paper reviews the debate between Carnap and Schrödinger about Hypothesis P (It is not only I who have perceptions and thoughts; other human beings have them too)–a hypothesis that underlies the possibility of doing science. For Schrödinger this hypothesis is not scientifically testable; for Carnap it is. But Schrödinger and Carnap concede too much to each other and miss an alternative understanding: science does not depend on an explicit hypothesis concerning what other human beings see and think; it is (...) simply a practice of communication which anticipates or presupposes the perfect interchangeability of positions amongst the members of the linguistic community. The mentalistic vocabulary of folk-psychology, used by Carnap and Schrödinger, does not take first but last place in this perspective; because it does nothing but express after the event the confidence to which the disputants bear witness regarding a generally successful practice of communication.

We propose a synthetic description of Merleau-Ponty’s phenomenology with the aim of providing physicists and philosophers with an alternative linguistic and conceptual framework to address the logical and ontological problematics emerged in quantum mechanics. Phenomenology’s cognitive devices such as the dynamical relationship between object and horizon, the presumptive synthesis and the constitution of an ontology based on the indivisibility of object and subject, not only show hermeneutic efficacy when applied to the study of human perception, but may prove to be (...) sufficiently innovative to lead to novel insights towards the understanding of the quantum mechanical theoretical structure: the traditional tenet of quantum physics being in discontinuity with the major characteristics of classical physics is shaken at its fundaments and a new perspective of continuity between the two worlds is opened.

From the very beginning of ancient Greek philosophy up to the present day a puzzling correlation is found between rationality and reality. In this study this relation is examined with emphasis on the philosophical tradition of Aristotle and Aquinas. A comparison is made with the virtual reality created by computers and actual reality of our universe. The view expressed in the scientific neopositivism of Jordan and Mach is found to be an adequate approach to avoid contradictions in the interpretation of (...) modern physics. A challenging hypothesis is made by updating the Laplacian Demon by a powerful creative intellect in line with Judeo-Christian tradition. With this hypothesis a new light is shed on several fundamental issues in modern science. (shrink)

Essence and causes in and through the movements in Nature. From Aristotle and in dialogue with Alicia Juarrero: According to Aristotle there is an intrinsic relation between ordinary language, logic and ontology, which is a key element for the knowledge of reality. Such a relation is applied by the Stagirite in the sphere of nature as support for the analysis made by the incipient natural sciences of his time. Thus, Aristotle provided a unitary conception of nature and the sciences which (...) study it. His contributions are still relevant for the study of nature. This paper tries to show the present validity of the Aristotelian thought, provided it is understood in the appropriate way. This attempt is made by means of confronting Aristotle’s ideas with those of a contemporary proposal, namely Juarrero’s, which has nevertheless a similar intention. (shrink)

This paper examines the strengths and weaknesses of one of science's most pervasive and flexible metaprinciples;optimalityis used to explain utility maximization in economics, least effort principles in physics, entropy in chemistry, and survival of the fittest in biology. Fermat's principle of least time involves both teleological and causal considerations, two distinct modes of explanation resting on poorly understood psychological primitives. The rationality heuristic in economics provides an example from social science of the potential biases arising from the extreme flexibility of (...) optimality considerations, including selective search for confirming vidence, ex post rationalization, and the confusion of prediction with explanation. Commentators are asked to reflect on the extent to which optimality is an organizing principle of nature, a set of relatively unconnected techniques of science, a normative principle for rational choice and social organization, a metaphysical way of looking at the world, or something else still.

The main goal of this paper is to argue against Karl Rogers's attacks on realism in physics. Rogers argues that electrons do not exist independently of the relevant socio-technological process, but I show that such an assumption would make our best scientific theories incomprehensible. While the paper supports Rogers's attempts to refute positivism, it demonstrates that his own position is positivistic, and it corrects his overemphasis on the roles of technology and the experimenter. Rogers assumes that the founders of modern (...) science were simply mechanists, but I show how they were actually Platonic realists. Contrary to Rogers, realist faith in the fundamental unifying power of the laws of physics is shown to be reasonable, and any denial of this belief would imply that science is impossible. (shrink)

The term natural is effective in the marketing of a wide variety of foods. This ambiguous term carries important meaning in Western culture. To challenge an uncritical understanding of natural with respect to food and to explore the ambiguity of the term, the development of Western ideas of nature is first discussed. Personification and hypostasization of nature are given special emphasis. Leo Marx’s idea of the pastoral design in literature is then used to explore the meaning of natural as applied (...) to food, emphasizing Marx’s distinction between a sentimental and a complex pastoral. The latter is applied to natural as a means of collapsing a dichotomy of man and nature to the idea of second nature. From this perspective an understanding of the industrialization of the food system and the importance of local and organic food are considered. The extent to which processed foods might properly be considered natural is raised and discussed for several common foods. Although marketing of natural foods might make us think that we consume nature, I suggest that what is consumed is more appropriately second nature. I suggest that in order to maintain a critical perspective about one’s relationship to the natural world, everyone should make an attempt to experience the complex pastoral with respect to at least something that is consumed as food. When nature is understood as second nature in the context of a complex pastoral, the question of whether a food or ingredient is to be considered natural is replaced by deliberative thought based on our best knowledge and judgment, and the result will be less constrained by ideology.

The new science of Complexity explains that limited knowledge prevents societies from predicting and controlling their developments. But Complexity further suggests that nature uses the limits of knowledge to evolve, which turns an apparent obstacle into an opportunity to reevaluate governmental institutions. As in nature, the limits of knowledge lead social systems to evolve by individuating, liberating, and empowering their members. Societies individuate and liberate their members to probe environments and exploit opportunities. Societies empower individuals to globalize their findings which (...) requires constitutionally constraining governmental powers. Societies that respect human rights thus gain selective advantage. Showing that what nature is models what societies ought to be, Complexity may finesse the "naturalistic fallacy" of Hume and Moore. (shrink)
