It is essentially a truism that the natural sciences have little or no place for dogmatism; to the contrary, there is an underlying skepticism pervading all scientific propositions. Any philosophy which pretends to provide an adequate philosophy of science, should, it seems to me, exhibit epistemologically a corresponding skepticism. At the very least, such a philosophy should demonstrate a skepticism in its views of the “truth” of scientific statements.

Any physical theory which seriously proposes that events in the future may be the efficient causes of events in the past certainly may be regarded—at least at first glance—as a rather revolutionary doctrine. In a recent issue of the Reviews of Modern Physics commemorating Niels Bohr's sixtieth birthday, and under the editorship of the latest Nobel Prize winner in physics, W. Pauli, there appeared such a theory—written by Bohr's former student, J. A. Wheeler and Wheeler's associate at Princeton, R. P. (...) Feynman. The title of their paper appears harmless enough: “Interaction with the Absorber as the Mechanism of Radiation.” It is one part of a more comprehensive three-part paper intended for later publication as a general constructive critique of classical field theory and of the theory of action at a distance as propounded by Schwarzschild and Fokker.

A recent proposal by Dr. W. H. McCrae, cosmologist and mathematician, to the effect that decisions between such cosmogonies as those of Hoyle and of Gamow are experimentally impossible by virtue of a general cosmological indeterminacy principle, is here examined and elaborated upon. Some comments on the "antinomies" in Kant's "Critique of Pure Reason" are made in reference to this principle as well as to the Heisenberg indeterminacy principle. If McCrae's principle is accepted, we will have moved a long way (...) toward Kant's conclusion that a logically consistent understanding of an underlying "ultimate reality" is outside the confines of science--whatever one may think of Kant's own line of reasoning.

The philosopher who is interested in developments of modern physics may turn with some profit to an argument that has recently evolved between the late George Birkhoff and Hermann Weyl. Birkhoff and his associates have constructed a theory of relativity differing in various ways from Einstein's general theory. Weyl has offered a critical analysis of the Birkhoff theory along with a defense of the Einstein theory; and Birkhoff has presented his rebuttal to Weyl.

Some issues raised by parapsychological phenomena (psi) are examined in the light of their implications for a philosophy of science. It is shown that the kinds of problems psi poses for science vary with the way one conceives of science as well as one's conception of psi. It is suggested that psi may be a product of the fact that all of our scientific concepts are abstractions and therefore oversimplifications. This raises the possibility that our best conceptual technique for dealing (...) with psi is a non-discursive symbolism, since this would not demand "classes" (oversimplification). Implications of this approach are considered. (shrink)

Preparing the Next Generation of Oral Historians is an invaluable resource to educators seeking to bring history alive for students at all levels. Filled with insightful reflections on teaching oral history, it offers practical suggestions for educators seeking to create curricula, engage students, gather community support, and meet educational standards. By the close of the book, readers will be able to successfully incorporate oral history projects in their own classrooms.

In the Bayesian approach to quantum mechanics, probabilities—and thus quantum states—represent an agent’s degrees of belief, rather than corresponding to objective properties of physical systems. In this paper we investigate the concept of certainty in quantum mechanics. Particularly, we show how the probability-1 predictions derived from pure quantum states highlight a fundamental difference between our Bayesian approach, on the one hand, and Copenhagen and similar interpretations on the other. We first review the main arguments for the general claim that probabilities (...) always represent degrees of belief. We then argue that a quantum state prepared by some physical device always depends on an agent’s prior beliefs, implying that the probability-1 predictions derived from that state also depend on the agent’s prior beliefs. Quantum certainty is therefore always some agent’s certainty. Conversely, if facts about an experimental setup could imply agent-independent certainty for a measurement outcome, as in many Copenhagen-like interpretations, that outcome would effectively correspond to a preexisting system property. The idea that measurement outcomes occurring with certainty correspond to preexisting system properties is, however, in conflict with locality. We emphasize this by giving a version of an argument of Stairs [(1983). Quantum logic, realism, and value-definiteness. Philosophy of Science, 50, 578], which applies the Kochen–Specker theorem to an entangled bipartite system. (shrink)

One of the central aims of autism research is to identify specific neurodevelopmental mechanisms that cause and explain the visible autistic signs and symptoms. In this short paper, I argue that the persistent search for autism-specific pathophysiologies has two fundamental difficulties. The first regards the growing gap between basic autism science and clinical practice. The second regards the difficulties with demarcating autism as a psychiatric condition. Instead of the unremitting search for the neurobiological basis of autism, I suggest that basic (...) autism research should focus on experiences of impairment and distress, and on how these experiences relate to particular behaviors in particular circumstances, regardless of whether we are dealing with an autism diagnosis or not.

We prove a Gleason-type theorem for the quantum probability rule using frame functions defined on positive-operator-valued measures, as opposed to the restricted class of orthogonal projection-valued measures used in the original theorem. The advantage of this method is that it works for two-dimensional quantum systems and even for vector spaces over rational fields—settings where the standard theorem fails. Furthermore, unlike the method necessary for proving the original result, the present one is rather elementary. In the case of a qubit, we (...) investigate similar results for frame functions defined upon various restricted classes of POVMs. For the so-called trine measurements, the standard quantum probability rule is again recovered.

Although clinicians and researchers working in the field of autism are generally not concerned with philosophical categories of kinds, a model for understanding the nature of autism is important for guiding research and clinical practice. Contemporary research in the field of autism is guided by the depiction of autism as a scientific object that can be identified with systematic neuroscientific investigation. This image of autism is compatible with a permissive account of natural kinds: the mechanistic property cluster (MPC) account of (...) natural kinds, recently proposed as the model for understanding psychiatric disorders. Despite the heterogeneity, multicausality and fuzzy boundaries that complicate autism research, a permissive account of natural kinds (MPC kinds) provides prescriptive guidance for the investigation of objective causal mechanisms that should inform nosologists in their attempt to carve autism’s boundaries at its natural joints. However, this essay will argue that a mechanistic model of autism is limited since it disregards the way in which autism relates to ideas about what kind of behavior is abnormal. As historical studies and definitions of autism show, normative issues concerning disability, impairment and societal needs have been and still are inextricably linked to how we recognize and understand autism. The current search for autism’s unity in neurobiological mechanisms ignores the values, social norms and various perspectives on mental pathology that play a significant role in 'the thing called autism’. Autism research needs to engage with these issues in order to achieve more success in the effort to become clinically valuable. (shrink)

In this article, I argue that the history and philosophy of autism need to account for two kinds of autism. Contemporary autism research and practice is structured, directed and connected by an ‘ontological understanding of disease’. This implies that autism is understood as a disease like any other medical disease, existing independently of its particular manifestations in individual patients. In contrast, autism in the 1950s and 1960s was structured by a psychoanalytical framework and an ‘individual understanding of disease’. This implied (...) that autism was not a distinct disease but an idiosyncratic and meaningful response of the child to a disturbed development of the ego. These two kinds of autism are embedded in and reveal two very different ‘styles of psychiatric thought’. (shrink)

Die Rezeption von Literatur ist von besonderen Herausforderungen gekennzeichnet. Einerseits gibt es erlernbare Techniken des Lesens und Deutens, andererseits gibt es das Wissen um eine dennoch verbleibende Deutungsvielfalt. Statt die Ungewissheiten bei der Deutung zu beklagen, besteht die (in der Moderne zunehmend wichtiger werdende) Möglichkeit, diese Ungewissheit als produktiv zu deuten und das Lesen von Literatur als einen ästhetisch eröffneten Spielraum zu fassen, in dem wir gefahrlos unsere Kenntnisse, Erwartungen und Überzeugungen einsetzen, erproben und erweitern können. Es werden zunächst grundlegende (...) Fragen des Lesens und der Fiktion angesprochen, eine Bestimmung literaturwissenschaftlicher Arbeit entwickelt, um dann philosophische und theologische Integrationsbemühungen literarischer Werke kritisch zu beleuchten. Am Beispiel der Deutungsbedürftigkeit des Todes wird die Relevanz und der Eigensinn des Literarischen aufgezeigt. (shrink)

Der Beitrag beleuchtet die Struktur und Funktion forschender Laborpraxis vor dem Hintergrund verschiedener erkenntnis- und wissenschaftstheoretischer Positionen. Das Labor kann in seiner Relevanz unterschätzt werden – mit Blick auf die darin verrichteten praktischen Tätigkeiten, auf dabei erforderliche Urteilsbildungen und nicht zuletzt auf unverzichtbare Impulse für die Wissenschaft. Die abstrakte Gegenüberstellung von Theorie und Praxis ist aufzugeben. Zugleich sollte Wissenschaft weder allein über das Labor noch über die Theoriebildung bestimmt werden. Abschließend plädiert der Beitrag dafür, die skizzierten Fragestellungen in die Labordidaktik (...) sowie in die Planung und Durchführung von Lernlaboren einzubeziehen. (shrink)

Die strittige ‚Faktizität des Todes‘ eröffnet die Frage, wie man sich zu ihr stellen soll. Der Beitrag bietet ein Panorama beispielhafter Ex-plikationen von Haltungen gegenüber dem Tod. Hierbei wird aufgewiesen, dass die bloße Bejahung des Todes unzureichend ist, wenn nicht zugleich die abträglichen und abgründigen Aspekte von Sterben und Tod wahrgenommen werden. Eine Abwägung der Effekte ist allerdings kaum durchführbar und das verbreitete Argument drohender Langeweile problematisch. Mit dem Hinweis auf Aristoteles und Kant werden Lektüremöglichkeiten aufgezeigt, die vertraute Topoi einer (...) Ars Moriendi aufbrechen und ein Verständnis gelingender Lebensführung entwickeln, die auf Fortsetzung drängt. Uto- pische Entwürfe der Überwindung des Todes werden zuletzt kritisch diskutiert.
