Die vorliegende Schrift unternimmt eine Revision des vorherrschenden Bildes der Rolle und der Konzeptionen von Moral und Ethik im Wiener Kreis. Dieses Bild wird als zu einseitig und undifferenziert zurückgewiesen. Die Ansicht, die Mitglieder des Wiener Kreises hätten kein Interesse an Moral und Ethik gezeigt, wird widerlegt. Viele Mitglieder waren nicht nur moralisch und politisch interessiert, sondern auch engagiert. Des Weiteren vertraten nicht alle die Standardauffassung logisch-empiristischer Ethik, die neben der Anerkennung deskriptiv-empirischer Untersuchungen durch die Ablehnung jeglicher normativer und inhaltlicher (...) |

This volume explores how functional brain imaging techniques like positron emission tomography have influenced cognitive studies. The first chapter outlines efforts to relate human thought and cognition in terms of great books from the late 1800s through the present. Chapter 2 describes mental operations as they are measured in cognitive science studies. It develops a framework for relating mental operations to activity in nerve cells. In Chapter 3, the PET method is reviewed and studies are presented that use PET to (...) |

There are methodological problems with the new techniques reviewed by Posner & Raichle. Some brain mechanisms are not detected by the temporal and spatial resolution. Questions are also raised by the stimulation paradigms. |

In Posner & Raichle's (1994) book, two essential and strictly related limitations of cognitive neurophysiology are not sufficiently enhanced: (1) The problem of “coding,” namely the capability of a natural brain to redefine its own “basic symbols” as a function of a changing environment; (2) the inadequacy of a Hebbian rule to reckon with complex computational problems such as those solved by real brains. |

Karl Popper and Friedrich von Hayek became close friends soon after they first met in the early 1930s. Ever since, they discussed their ideas intensively on many occasions. But even though an analysis of the origins and contents of their ideas and correspondence reveals a number of important and fundamental differences, they rarely criticize each other in their published work. The article analyzes in particular the different ideas they have on the role of reason in society and on rationalism and (...) |

In his biography of Karl Popper, Malachi Hacohen brilliantly reconstructs the development of Popper's ideas through 1946, correcting many errors regarding the sequence of their emergence. In addition he recreates Popper's Vienna and provides insights into Popper's complex personality. A larger goal of Hacohen's narrative is to show the relevance of Popper's philosophical and political thought for the left. Unfortunately this leads him to neglect and distort certain aspects of the story he tells, particularly when it comes to the relationship (...) |

Semantic information is usually supposed to satisfy the veridicality thesis: p qualifies as semantic information only if p is true. However, what it means for semantic information to be true is often left implicit, with correspondentist interpretations representing the most popular, default option. The article develops an alternative approach, namely a correctness theory of truth (CTT) for semantic information. This is meant as a contribution not only to the philosophy of information but also to the philosophical debate on the nature (...) |

Popper's well-known demarcation criterion has often been understood to distinguish statements of empirical science according to their logical form. Implicit in this interpretation of Popper's philosophy is the belief that when the universe of discourse of the empirical scientist is infinite, empirical universal sentences are falsifiable but not verifiable, whereas the converse holds for existential sentences. A remarkable elaboration of this belief is to be found in Watkins's early work on the statements he calls “all-and-some,” such as: “For every metal (...) |

Taking its clues from Popperian philosophy of science, cladistics adopted a number of assumptions of the empiricist tradition. These include the identification of a dichotomy between observation reports and theoretical statements and its subsequent abandonment on the basis of the insight that all observation reports are theory-laden. The neglect of the ‘context of discovery’, which is the step of theory (hypothesis) generation. The emphasis on coherentism in the ‘context of justification’, which is the step of evaluation of the relative merits (...) |

This paper describes the development of theories of scientific explanation since Hempel's earliest models in the 1940ies. It focuses on deductive and probabilistic whyexplanations and their main problems: lawlikeness, explanation-prediction asymmetries, causality, deductive and probabilistic relevance, maximal specifity and homogenity, the height of the probability value. For all of these topic the paper explains the most important approaches as well as their criticism, including the author's own accounts. Three main theses of this paper are: (1) Both deductive and probabilistic explanations (...) |

Logical positivism is often characterized as a set of naive doctrines on meaning, method, and metaphysics. In recent decades, however, historians have dismissed this view as a gross misinterpretation. This new scholarship raises a number of questions. When did the standard reading emerge? Why did it become so popular? And how could commentators have been so wrong? This essay reconstructs the history of a “caricature” and rejects the hypothesis that it was developed by ill-informed Anglophone scholars who failed to appreciate (...) |

The purpose of this work is to reconsider and critically discuss the conceptual foundations of modern biology and bio-sciences in general, and provide an epistemological guideline to help framing the teaching of these disciplines and enhancing the quality of their presentation in High School, Master and Ph.D. courses. After discussing the methodological problems that arise in trying to construct a sensible and useful scientific approach applicable to the study of living systems, we illustrate what are the general requirements that a (...) |

This paper takes up Shannon Rodgers’ 2016 critique of curriculum writers’ call for observable verbs, pp. 563–578), and argues that a more effective line of critique should focus not on metaphorical thinking, but on the notion of observation itself, by way of Nietzsche on metaphor, the history of astronomy, the non-existence of dragons and dissuading indigenous people from voting. |

Ever since the first meeting of the proponents of the emerging Logical Empiricism in 1923, there existed philosophical differences as well as personal rivalries between the groups in Berlin and Vienna, headed by Hans Reichenbach and Moritz Schlick, respectively. Early theoretical tensions between Schlick and Reichenbach were caused by Reichenbach’s Kantian roots, who himself regarded the Vienna Circle as a sort of anti-realist “positivist school”—as he described it in his Experience and Prediction. One result of this divergence was Schlick’s preference (...) |

The eminent mathematical physicist Sir Hermann Bondi once said: “There is no more to science than its method, and there is no more to its method than Popper has said.” Indeed, many regard Sir Karl Raimund Popper the greatest philosopher of science in our generation. Much of what Popper “has said” refers to physics, but physicists, generally speaking, have little knowledge of what he has said. True, Popper's philosophy of science and, in particular, his realistic interpretation of quantum mechanics deviates (...) |

Hypothetico-deductive (H-D) confirmation builds on the idea that confirming evidence consists of successful predictions that deductively follow from the hypothesis under test. This article reviews scope, history and recent development of the venerable H-D account: First, we motivate the approach and clarify its relationship to Bayesian confirmation theory. Second, we explain and discuss the tacking paradoxes which exploit the fact that H-D confirmation gives no account of evidential relevance. Third, we review several recent proposals that aim at a sounder and (...) |

The paper approaches the topic of what a general philosophy of science could mean today from the perspective of a historical epistemology. Consequently, in a first step, the paper looks at the notion of generality in the sciences, and how it evolved over time, on the example of the life sciences. In the second part of the paper, the urgency of a general philosophy of science is located in the history of philosophy of science. Two attempts at the beginning of (...) |

What happens when management consultants enter the academic arena and offer their services to universities? In the following article, we examine this question by drawing on findings from a qualitative study based on a series of 30 interviews with senior management consultants and academic managers in Germany. The aim of this explorative study is, first of all, to provide theoretically informed observations about the working mechanisms of management consulting in academia. A second, and related objective, is to contribute to the (...) |

We give an example from the theory of Markov decision processes which shows that the “optimism in the face of uncertainty” heuristics may fail to make any progress. This is due to the impossibility to falsify a belief that a (transition) probability is larger than 0. Our example shows the utility of Popper’s demand of falsifiability of hypotheses in the area of artificial intelligence. |

Summary I try to apply Lakatos's metacriterion of the rationality of normative philosophies of science to normative political theories, stressing that Lakatos's metacriterion is not only an extension of Popper's idea of tests by potentially falsifyingdescriptive basic judgments to tests by potentially falsifyingnormative judgments. Rather, its application is a test by demonstrating the tested theory's capability of reconstructing its own history as rational. Finally I argue that the tradition of utilitarian political theories is fittest to be confirmed by a Lakatosian (...) |

The distinction between sociology of science on the one hand and methodology and systematics on the other, is an established historical fact. Thus, even in modern methodologically orientated philosophy, epistemological analyses still tend to disregard the pragmatic contexts within which scientific knowledge is produced, processed and applied. This situation also reflects the well-known fact that philosophy of science has largely ignored the conceptual and methodological foundations of technology, that is, those disciplines directly and explicitly linked to the practical implications and (...) |

Introduction to Synthese SI: Systematicity: The Nature of Science? |

In this essay, which was his presidential address to the Philosophy of Science Association, Ernan McMullin argued that the watershed between “classic” philosophy of science and the “new” philosophy of science can best be understood by analyzing the change in our perception of the role played by values in science. He begins with some general remarks about the nature of value, goes on to explore some of the historical sources for the claim that judgement in science is value‐laden, and concludes (...) |

This paper responds to the essay reviews by David Haig, Alan Love and Rachel Brown of my recently published book “Homology, Genes and Evolutionary Innovation”. The issues addressed here relate to: the notion of classes and individuals, issues of explanatory value of adaptive and structuralist explanations in evolutionary biology, the role of homology in evolutionary theory, the limits of a pluralist stance vis a vis alternative explanations of homology, as well as the question whether and to what extend the perspective (...) |

Images of mindmarks a new era in human cognitive neuroscience. Despite the difficult conceptual problems associated with using group-averaged data and paired subtractions, human PET images converge well with existing data from other areas of cognitive neuroscience while opening up new theoretical and experimental possibilities. However, greater attention to individual differences might prove necessary in the study of culturally driven adaptations such as literacy. |

The approach adopted by Posner & Raichle in this book, with its strong emphasis on the cognitive level of description, is ideally suited to the study of psychotic illnesses. However, their discussion of depression and schizophrenia is based on a very small number of studies and involves ad hoc arguments derived largely from neuroanatomy. Their conclusions are almost certainly wrong. |

The authors ofImages of mindhave been highly successful in unravelling the neural basis of complex brain functions. Their emphasis on top-down processingin experimental neuroscience is especially important and, it is hoped, influential. Tracking brain activation accurately botli in space and in time would benefit from studiesofindividual subjects without relying on grand average data. |

Carnap’s work was instrumental to the liberalization of empiricism in the 1930s that transformed the logical positivism of the Vienna Circle to what came to be known as logical empiricism. A central feature of this liberalization was the deployment of the Principle of Tolerance, originally introduced in logic, but now invoked in an epistemological context in “Testability and Meaning”. Immediately afterwards, starting with Foundations of Logic and Mathematics, Carnap embraced semantics and turned to interpretation to guide the choice of a (...) |

Since the birth of computing as an academic discipline, the disciplinary identity of computing has been debated fiercely. The most heated question has concerned the scientific status of computing. Some consider computing to be a natural science and some consider it to be an experimental science. Others argue that computing is bad science, whereas some say that computing is not a science at all. This survey article presents viewpoints for and against computing as a science. Those viewpoints are analyzed against (...) |

It is widely held that falsification of statistical hypotheses is impossible. This view is supported by an analysis of the most important theories of statistical testing: these theories are not compatible with falsificationism. On the other hand, falsificationism yields a basically viable solution to the problems of explanation, prediction and theory testing in a deterministic context. The present paper shows how to introduce the falsificationist solution into the realm of statistics. This is done mainly by applying the concept of empirical (...) |

According to the article, Neurath's reflexive epistemology—expressed by the metaphor of the ship in need of reconstruction on the open sea—represents a philosophical alternative to the classical and contemporary forms of scientific realism and ethical cognitivism, including Popper's falsificationism. Against Quine's reductive interpretation of Neurath's boat argument as the basis for a 'naturalized epistemology,' the article maintains that the metaphor suggests the idea of an insuperable situation of linguistic and conceptual circularity. This prevents any attempt at self-foundation in scientific knowledge, (...) |

In artificial intelligence (AI), a number of criticisms were raised against the use of probability for dealing with uncertainty. All these criticisms, except what in this article we call the non-adequacy claim, have been eventually confuted. The non-adequacy claim is an exception because, unlike the other criticisms, it is exquisitely philosophical and, possibly for this reason, it was not discussed in the technical literature. A lack of clarity and understanding of this claim had a major impact on AI. Indeed, mostly (...) |

It is shown in a literature review, that in the Typostrophic Theory autonomous mechanisms in the organism are considered as the factors which play a decisive role in orienting and controlling the evolutionary process. Selection is a controlling factor of only minor importance. The Synthetic Theory, on the other side, says that phylogenetic changes are not random or controlled by “internal factors” but can always be considered as adaptive remodellings. They are achieved by selection acting on the variation within populations. (...) |

The paper exposes the principal procedures of assessing methodological theories. The first one is based on a consensus about the aims of science, the second uses epistemological criteria, and the third checks the adequacy of methodological requirements against the history of science. This third procedure is singled out for a more detailed treatment. It is argued that rational reconstruction constitutes a separate level of historiography and concerns historical explanation. The subject of a rational reconstruction is the methodological explanation of all (...) |
