Edmund Husserl’s eidetic phenomenology seeks a priori knowledge of essences and eidetic laws pertaining to conscious experience and its objects. Husserl believes that such eidetic knowledge has a higher epistemic status than the inherently fallible empirical knowledge, but a closer reading of his work shows that even eidetic claims are subject to error and open to modification. In this article, I develop a self-correcting account of Husserl’s method of eidetic variation, arguing that eidetic variation plays a critical role in both (...) challenging and improving upon the eidetic results in phenomenology. More specifically, I argue that the self-correcting account of eidetic variation 1) is consistent with Husserl’s own formulations of his eidetic methodology and epistemic principles; 2) captures the dual epistemic function of eidetic variation as means for both testing and intuitively validating eidetic claims; and 3) offers methodological support for contemporary attempts to integrate eidetic variation with non-eidetic methods and resources. To substantiate these claims, I first contrast the self-correcting account with the falsificationist interpretations of eidetic variation. Then, I turn to three applications of eidetic variation in order to examine how eidetic phenomenology could draw from real-life deviations, artificial variations, and critical–historical reflection. The goal is to lay the methodological groundwork for a self-correcting and integrative account of eidetic variation and illustrate its usefulness in research practice. (shrink)

The psychological mechanisms implicated in psychopathy do not limit their activity to those behaviors that support a cheater strategy in social games. They result in a number of other clearly maladaptive behaviors that do not directly involve other individuals. Thus, any gains that might arise from the use of a cheater strategy in social situations are probably lost elsewhere.

Many of Tarski’s better known papers are either about or include lengthy discussions of how to properly define various concepts: truth, logical consequence, semantic concepts, or definability. In general, these papers identify two primary conditions for successful definitions: formal correctness and material adequacy. Material adequacy requires that the concept expressed by the formal definition capture the intuitive content of truth. Our primary interest in this paper is to better understand Tarski’s thinking about material adequacy, and whether components of his view (...) developed over time. More precisely, we are concerned with how Tarski’s understanding of the content of the common-sense, every-day usage of truth may have developed over time. We distinguish this concern from the character of the extensional criterion of adequacy Tarski proposes: that a materially adequate definition must entail all instances of Convention T. We will develop our reading of Tarski as follows: first, we will review the “Polemical Remarks,” focusing primarily on §§14 and 17, and Tarski’s references to Naess’ empirical research. Next, we will provide a summary and discussion of Naess’ work, especially his findings with respect to Tarski’s definition of truth and his research that suggests there is no single common or everyday concept of truth. Third, we will consider several possible objections to our interpretation of the Tarski–Naess dialectic. We will conclude that Tarski’s conception of material adequacy developed over time, potentially because of what he had learned through his interactions with Naess. (shrink)

We propose that Mealey's model is limited in its description of sociopathy because it does not provide an adequate role for the main organ mediating genes and behavior, namely, the brain. Further, on the basis of our research, we question the view of sociopaths as a homogeneous group.

According to the instrumentalism of Friedman and Machlup it is irrelevant whether the explanatory principles or “assumptions” of a theory satisfy any criterion of “plausibility,” “realism,” “credibility,” or “soundness.” In this view the main or only criterion for selecting theories is whether a theory yields empirically testable implications that turn out to be consistent with observations. All we should require or expect from a theory is that it is a useful instrument for the purpose of prediction. Considerations of the “efficiency” (...) of a theory for the purpose of ordering our experiences are permitted, but considerations of “plausibility” are not. “Explanatory assumptions” are not really explanatory in the sense that they claim to represent underlying causal processes in reality; they only serve to generate, by deduction, implications that are in accordance with as many observations as possible. (shrink)

Mealey's data do not support her dichotomous model of primary and secondary sociopathy; this data supports the view that there is a continuum of degrees of sociopathy, from zero to the maximal manifestation. There are multitudes of factors that can contribute to sociopathy and the countless different mixes of them can produce multiple degrees and variations of sociopathic behavior.

Mealey's excellent target article rests on several assumptions that may be questioned, including the overarching assumption that sociopathy reflects the failure of a small minority of males to cooperate with the larger group. I suggest that violent competition in ancestral bands cheatinggame was the primary evolutionary precursor of sociopathy. Today's violent sociopath is far more a than a failed cooperator.

While developing his theory of world 3, Popper rejects two claims made by Plato: first, that the inhabitants of world 3, ideas, are a source of ultimate explanation, a divine revelation of truth, and second, that these ideas are unchanging. I will rehabilitate the second claim. Man does not construct world 3 by creating his theories, nor is it a source of ultimate truth. Instead, world 3 is discovered by man, and it destroys some of his theories: destructive Platonism. I (...) discuss the impact of the modified position on the Grundlagenstreit in mathematics, taking into account Gillies’s constructive Aristotelianism. I then turn to the philosophy of computers and discuss how destructive Platonism relates to computers and the Internet. In particular, I criticize Popper’s claim that computers are nothing but elaborate pens as too pessimistic and incautious, and the fashionable “singularity” theory as too optimistic and at the same time too fatalistic. In my closing remarks, as an antidote against both views, I provide a more modest and reasonable speculation about the ultimate goal and meaning of life. (shrink)

Karl Popper identified Xenophanes of Colophon (570−478 BCE) as the originator of the method of conjectures and refutations. This essay explores this claim, and the methods of both philosophers (section 1). Disparagement (ancient and modern) of Xenophanes has been misguided (section 2). Xenophanes, a critical rationalist and realist, pioneered philosophy of religion (section 3) and epistemology (section 4), but his method was not confined to falsificationism, and appears compatible with inductivism and abductionism (section 5). The method employed by Popper in (...) interpreting Herodotus in support of his conjectures about Xenophanes is typical of the multiple-strand reasoning characteristic of the humanities, and is as much inductivist or abductionist as refutationist (section 6). Popper’s theories about Xenophanes are convincing; but even if Popperians would claim that Popper’s refutationism largely fits the natural sciences, his application of it to history is implausible, and conflicts with own practice (section 7). An appendix reflects on Popper’s interest in cultured refugees. (shrink)

Science can reinforce the healthy aspects of the politics of the policy process, to identify and further the public interest by discrediting policy options serving only special interests and helping to select among “science-confident” and “hedging” options. To do so, scientists must learn how to manage and communicate the degree of uncertainty in scientific understanding and prediction, lest uncertainty be manipulated to discredit science or to justify inaction. For natural resource and environmental policy, the institutional interests of government agencies, as (...) well as private interests, pose challenges of suppression, over-simplification, or distortion of scientific information. Scientists can combat these maneuvers, but must also look inward to ensure that their own special interests do not undermine the usefulness of science. (shrink)

Two specific aspects of Mealey's model are questioned: (1) the application of the concept of Evolutionarily Stable Strategy to all alternative strategies, including those that involve reduced lifetime reproductive success; and (2) the evidence for the dual role of testosterone, which is based mainly on studies of a modulating effect on aggression.

The recent drastic development of agriculture, together with the growing societal interest in agricultural practices and their consequences, pose a challenge to agricultural science. There is a need for rethinking the general methodology of agricultural research. This paper takes some steps towards developing a systemic research methodology that can meet this challenge – a general self-reflexive methodology that forms a basis for doing holistic or (with a better term) wholeness-oriented research and provides appropriate criteria of scientific quality.From a philosophy of (...) research perspective,science is seen as an interactive learning process with both a cognitive and a social communicative aspect. This means, first of all,that science plays a role in the world that it studies. A science that influences its own subject area, such as agricultural science, is named a systemic science. From this perspective, there is a need to reconsider the role of values in science. Science is not objective in the sense of being value-free.Values play, and ought to play, an important role in science – not only in form of constitutive values such as the norms of good science, but also in the form of contextual values that enter into the very process of science. This goes against the traditional criterion of objectivity. Therefore, reflexive objectivity is suggested as a new criterion for doing good science, along with the criterion of relevance. Reflexive objectivity implies that the communication of science must include the cognitive context, which comprises the societal,intentional, and observational context. Ina ccordance with this, the learning process of systemic research is shown as a self-reflexive cycle that incorporates both an involved actor stance and a detached observer stance. The observer stance forms the basis for scientific communication.To this point, a unitary view of science as a learning process is employed. A second important perspective for a systemic research methodology is the relation between the actual,different, and often quite separate kinds of science. Cross-disciplinary research is hampered by the idea that reductive science is more objective, and hence more scientific, than the less reductive sciences of complex subject areas – and by the opposite idea that reductive science is necessarily reductionistic. Taking reflexive objectivity as a demarcator of good science, an inclusive framework of science can be established. The framework does not take the established division between natural, social, and human science as a primary distinction of science.The major distinction is made between the empirical and normative aspects of science,corresponding to two key cognitive interests.Two general methodological dimensions, the degree of reduction of the research world and the degree of involvement in the research world, are shown to span this framework. The framework can form a basis for transdisciplinary work by way of showing the relation between more and less reductive kinds of science and between more detached and more involved kinds of science and exposing the abilities and limitations attendant on these methodological differences.

In this essay it is argued that (1) if the process of scientific inquiry were to continue foreever, then science would ultimately terminate in the acceptance of a single theoretical framework better than all conceivable others, and (2) there is some evidence in favor of the view that science will continue unto eternity but no evidence in favor of the contrary view. In arguing for claim (1) it is claimed that if we are to understand the sense in which science (...) is progressive we must mean either that science progresses by approximating a final goal which, given an infinite process, will be attained, or that science progresses simply in the sense of expanding a body of funded knowledge such that, given an infinite process, the body of funded knowledge expands ad infinitum. That the second member of this disjunct is false and that the first cannot be shown to be false follows largely from a discussion and rejection of all available arguments (five) against the hypothesis proposed in (1). Further, an argument provided by Peirce (and suitably supplemented) provides additional positive evidence for the truth of the first member. No such argument exists for the truth of the second member. In arguing for claim (2) it is held that evidence in favor of a belief can be purchased by the positive moral value likely to occur as a result of accepting the beliefs, and that there is at least one moral value which accrues to the belief that inquiry will continue forever but which does not accrue to the belief that inquiry will not continue forever. In short, while there is no systematic evidence for or against the view that inquiry will continue forever, we have the right (and duty) to believe that inquiry will continue forever but we do not have the right (and duty) to believe the contrary.

Bayes’ rule shows how one might rationally change one’s beliefs in the light of evidence. It is the foundation of a statistical method called Bayesianism. In health care research, Bayesianism has its advocates but the dominant statistical method is frequentism. There are at least two important philosophical differences between these methods. First, Bayesianism takes a subjectivist view of probability (i.e. that probability scores are statements of subjective belief, not objective fact) whilst frequentism takes an objectivist view. Second, Bayesianism is explicitly (...) inductive (i.e. it shows how we may induce views about the world based on partial data from it) whereas frequentism is at least compatible with non-inductive views of scientific method, particularly the critical realism of Popper. Popper and others detail significant problems with induction. Frequentism’s apparent ability to avoid these, plus its ability to give a seemingly more scientific and objective take on probability, lies behind its philosophical appeal to health care researchers. However, there are also significant problems with frequentism, particularly its inability to assign probability scores to single events. Popper thus proposed an alternative objectivist view of probability, called propensity theory, which he allies to a theory of corroboration; but this too has significant problems, in particular, it may not successfully avoid induction. If this is so then Bayesianism might be philosophically the strongest of the statistical approaches. The article sets out a number of its philosophical and methodological attractions. Finally, it outlines a way in which critical realism and Bayesianism might work together. (shrink)

The main claim of this paper is that the method outlined and used in Aristotle’s Ethics is an appropriate and credible one to use in bioethics. Here “appropriate” means that the method is capable of establishing claims and developing concepts in bioethics and “credible” that the method has some plausibility, it is not open to obvious and immediate objection. It begins by suggesting why this claim matters and then gives a brief outline of Aristotle’s method. The main argument is made (...) in three stages. First, it is argued that Aristotelian method is credible because it compares favourably with alternatives. In this section it is shown that Aristotelian method is not vulnerable to criticisms that are made both of methods that give a primary place to moral theory (such as utilitarianism) and those that eschew moral theory (such as casuistry and social science approaches). As such, it compares favourably with these other approaches that are vulnerable to at least some of these criticisms. Second, the appropriateness of Aristotelian method is indicated through outlining how it would deal with a particular case. Finally, it is argued that the success of Aristotle’s philosophy is suggestive of both the credibility and appropriateness of his method. (shrink)

The symposium on Francesco Guala’s Understanding Institutions was thought provoking. Five critical papers took issue with Guala’s reconciliation of the game-theoretical view of institutions and the rule-governed view. We offer some critical commentary that adopts a different perspective. We agree that institutions are central to social life and, thus, also to the social sciences; they are also prior to and more fundamental than individuals. We add some historical points on the ways previous philosophers thought about institutions, and we come at (...) this from a philosophical viewpoint that is not that of analytic philosophy but rather that of Popper’s critical rationalism. In that framework, we espouse an idea of the relation between philosophy and the philosophy of science that is different from that of Guala and his commentators, and we recommend a reformist philosophy of institutions that is neither radical nor traditionalist and that makes better sense of the institution of the scholarly symposium than do...

This Companion to the philosophy of science reflects fairly well the gloomy state of affairs in this subfield at its best—concerns, problems, prejudices, and all. The field is still stuck with the problem of justification of science, refusing to admit that there is neither need nor possibility to justify science and forbid dissent from it.

Arguably no concept is more fundamental to science than that of causality, for investigations into cases of existence, persistence, and change in the natural world are largely investigations into the causes of these phenomena. Yet the metaphysics and epistemology of causality remain unclear. For example, the ontological categories of the causal relata have been taken to be objects (Hume 1739), events (Davidson 1967), properties (Armstrong 1978), processes (Salmon 1984), variables (Hitchcock 1993), and facts (Mellor 1995). (For convenience, causes and effects (...) will usually be understood as events in what follows.) Complicating matters, causal relations may be singular (Socrates’s drinking hemlock caused Socrates’s death) or general (Drinking hemlock causes death); hence the relata might be tokens (e.g., instances of properties) or types (e.g., types of events) of the category in question. Other questions up for grabs are: Are singular causes metaphysically and/or epistemologically prior to general causes or vice versa (or neither)? What grounds the intuitive asymmetry of the causal relation? Are macro-causal relations reducible to micro-causal relations? And perhaps most importantly: Are causal facts (e.g., the holding of causal relations) reducible to non-causal facts (e.g., the holding of certain spatiotemporal relations)? (shrink)

In the article the main trends of modern philosophical theology are considered in the perspective of methodological tasks. Based on the diversity of the post-secular philosophical situation, the place of theology oft en turns out to be not only in the series of theological disciplines, but also acquires features of interdisciplinarity. Theological studies aimed at solving the problems of humanity, history, and time, combine hermeneutics and philosophical anthropology, philosophy of language and psychological methods, oft en becoming an experimental space for (...) applying of humanitarian approaches. In the paper the ideas of theologians and philosophers of the Bultmann and post-Bultman periods are compared. (shrink)

Some scientific categories seem to correspond to genuine features of the world and are indispensable for successful science in some domain; in short, they are natural kinds. This book gives a general account of what it is to be a natural kind and puts the account to work illuminating numerous specific examples.

The use of multiple means of determination to “triangulate” on the existence and character of a common phenomenon, object, or result has had a long tradition in science but has seldom been a matter of primary focus. As with many traditions, it is traceable to Aristotle, who valued having multiple explanations of a phenomenon, and it may also be involved in his distinction between special objects of sense and common sensibles. It is implicit though not emphasized in the distinction between (...) primary and secondary qualities from Galileo onward. It is arguably one of several conceptions involved in Whewell’s method of the “consilience of inductions” (Laudan 1971) and is to be found in several places in Peirce. (From M. Brewer and B. Collins, eds., (1981); Scientific Inquiry in the Social Sciences (a festschrift for Donald T. Campbell), San Francisco: Jossey-Bass, pp. 123–162.). (shrink)

Contemporary philosophy often chants the mantra, ‘Philosophy is continuous with science.’ Now Shepanski gives it a clear sense, by extracting from W. V. Quine’s writings an explicit normative epistemology – i.e. an explicit set of norms for theorizing – that applies to philosophy and science alike. It is recognizably a version of empiricism, yet it permits the kind of philosophical theorizing that Quine practised all his life. Indeed, it is that practice, more than any overt avowals, that justifies attributing this (...) set of norms to Quine. -/- The Quinean epistemology is supported by a metaphilosophy that judges epistemologies by the tenability of their consequences. Shepanski explores the Quinean epistemology’s consequences for inductive and abductive inference, for mathematical entities, for science and for common sense. Moreover, he finds that it continues to be fruitful, as illustrated by a case study in which Quinean methods lead to a new formal treatment of the propositional attitudes. Finally, there is critical discussion of popular alternative views, including foundationalism, the centrality of knowledge, and Quine’s own epistemological naturalism. -/- By focusing on Quine’s normative epistemology, Shepanski illuminates a part of Quine’s thought that has hitherto been insufficiently discussed, and provides a tractable starting point for readers who are new to Quine. Most importantly, he isolates the part of Quine’s thought that has the greatest potential impact outside epistemology, outside philosophy of language, and even outside philosophy. (shrink)

The traditional conception of knowledge is justified, true belief. If one looks at a modern textbook on epistemology, the great bulk of questions with which it deals are to do with personal knowledge, as embodied in beliefs and the proper experiences that someone ought to have had in order to have the right (or justification) to know. I intend to argue that due to the explosive growth of knowledge whose domain is “outside the head”, this conception has outlived its relevance. (...) -/- On the other hand, Karl Popper’s (1934) Falsificationism, with its emphasis on the objective character of knowledge, is not only a sounder, but also a more appropriate theory of knowledge for understanding the nature and growth of civilization. Later, Popper (1945) generalized this approach to obtain critical rationalism, in which all claims to knowledge, whether scientific or otherwise, are understood as objective solutions to objective problems and can be evaluated by other non-observational - types of criticism. I will first argue that Popper’s methodology is quite suited to the view that knowledge is an objective autonomous product and then adduce his theory of world 3, an ontology that neatly wraps up various considerations. World 3 is the domain of abstract products of the human mind that now have a life of their own, outside of human heads: theories, arguments, problems, plans, etc. I then adduce some other arguments for the autonomous quality of knowledge.

This volume examines the limitations of mathematical logic and proposes a new approach to logic intended to overcome them. To this end, the book compares mathematical logic with earlier views of logic, both in the ancient and in the modern age, including those of Plato, Aristotle, Bacon, Descartes, Leibniz, and Kant. From the comparison it is apparent that a basic limitation of mathematical logic is that it narrows down the scope of logic confining it to the study of deduction, without (...) providing tools for discovering anything new. As a result, mathematical logic has had little impact on scientific practice. Therefore, this volume proposes a view of logic according to which logic is intended, first of all, to provide rules of discovery, that is, non-deductive rules for finding hypotheses to solve problems. This is essential if logic is to play any relevant role in mathematics, science and even philosophy. To comply with this view of logic, this volume formulates several rules of discovery, such as induction, analogy, generalization, specialization, metaphor, metonymy, definition, and diagrams. A logic based on such rules is basically a logic of discovery, and involves a new view of the relation of logic to evolution, language, reason, method and knowledge, particularly mathematical knowledge. It also involves a new view of the relation of philosophy to knowledge. This book puts forward such new views, trying to open again many doors that the founding fathers of mathematical logic had closed historically. (shrink)

Science is a dynamic process in which the assimilation of new phenomena, perspectives, and hypotheses into the scientific corpus takes place slowly. The apparent disunity of the sciences is the unavoidable consequence of this gradual integration process. Some thinkers label this dynamical circumstance a ‘crisis’. However, a retrospective view of the practical results of the scientific enterprise and of science itself, grants us a clear view of the unity of the human knowledge seeking enterprise. This book provides many arguments, case (...) studies and examples in favor of the unity of science. These contributions touch upon various scientific perspectives and disciplines such as: Physics, Computer Science, Biology, Neuroscience, Cognitive Psychology, and Economics. (shrink)

This book is a synthesis of more than three decades of research into the concept of time and its semiotic nature. If traditional philosophy – and philosophy of time should be no exception – in the shadow of advancing biology can be said to have reached an impasse, one important reason for this, in harmony with Wittgenstein’s vision, appears to have been its lack of appropriate tools for explicating language. The present theory of time proceeds, accordingly, from the exploration of (...) temporal expressions in language as an evolutionary fact. It derives in a hypothetical, coherent feedback process of hierarchically ordered distinctions the semantics of time from its biologically dictated perceptual and cognitive-pragmatic origins. The corresponding abductive-regulative model is anchored in the assumption of biological rhythmization as the very foundation of perception and mental/physical action. Understood to originate in space and spatial perspective, time reveals itself as an instrument for temporal perspective on motion (events and situations) in a process of analysis, i.e., discontinuation of chaos made divisible and continuous by the rhythmical screen. Whereas traditional philosophy of time paid attention almost exclusively to the temporal category of tense, the biopragmatic model sees strong evidence in the perspectival nature of time for ascribing the decisive, and probably universal, role in temporal analysis to the linguistic category of aspect. Aspect may, according to the present findings, be assumed to partake already of change-of-state and cause-effect analysis without which man’s adaptation to new situations – and precondition for survival – would be inconceivable. The proposed model of space/time cognition, inspired by Hegelian dialectics, Heidegger-Gadamer’s hermeneutic circle and Peircean logic, makes Kantian a priori superfluous and liberates time from its enigmatic appearance. For the first time in temporal studies it thus appears possible to derive hypothetically linguistic expressions of time all the way from pretemporal, homogeneous continuity effected by biological rhythmization, via pretemporal metonymic (Gestalt), chunk-wise partitioning – as a general precondition for the perception and, based on primary metaphorization, the cognition of things, space and motion – to temporal analysis/discontinuation proper, primarily by aspectual perspective, and the subsequent synthesized, heterogeneous continuity of temporally ordered events. The conception of time, so disastrous for modern temporal logic, i.e., as moving object assigned extension, divisible continuity (‛linearity’) and direction, can be shown to have emerged as a result of secondary metaphorization.

This thesis offers a naturalist revision of Alain Badiou’s philosophy. This goal is pursued through an encounter of Badiou’s mathematical ontology and theory of truth with contemporary trends in philosophy of mathematics and philosophy of science. I take issue with Badiou’s inability to elucidate the link between the empirical and the ontological, and his residual reliance on a Heideggerian project of fundamental ontology, which undermines his own immanentist principles. I will argue for both a bottom-up naturalisation of Badiou’s philosophical approach (...) to mathematics and a top-down naturalisation. Articulating my particular understanding of what realism and naturalism should commit us to, I propose a creative fusion of Badiou’s attention to metamathematical results with a structural-informational metaphysics, proposing a ‘matherialism’ uniting the more daring speculative insights of the former with the naturalist and empiricist commitments motivating the latter.
