In 1957, Feyerabend delivered a paper titled ‘On the Quantum-Theory of Measurement’ at the Colston Research Symposium in Bristol to sketch a completion of von Neumann's measurement scheme without collapse, using only unitary quantum dynamics and well-motivated statistical assumptions about macroscopic quantum systems. Feyerabend's paper has been recognised as an early contribution to quantum measurement, anticipating certain aspects of decoherence. Our paper reassesses the physical and philosophical content of Feyerabend's contribution, detailing the technical steps as well as its overall philosophical (...) motivations and consequences. Summarising our results, Feyerabend interpreted collapse as a positivist assumption in quantum mechanics leading to a strict distinction between the uninterpreted formalism of unitary evolution in quantum mechanics and the classically interpreted observational language describing post-measurement outcomes. Thus Feyerabend took the no-collapse completion of the von Neumann measurement scheme to show the dispensability of the positivist assumption, leading the way to a realistic interpretation of quantum theory. We note, however, that there are substantial problems with his account of measurement that bring into question its viability as a legitimate foil to the orthodox view. We further argue that his dissatisfaction with the von Neumann measurement scheme is indicative of early views on theoretical pluralism. (shrink)

The demarcation between science and non-science seems to play an important role in the process of scientific change, as theories regularly transition from being considered scientific to being considered unscientific and vice versa. However, theoretical scientonomy is yet to shed light on this process. The goal of this paper is to tackle the problem of demarcation from the scientonomic perspective. Specifically, we introduce scientificity as a distinct epistemic stance that an agent can take towards a theory. We contend that changes (...) in this stance are to be traced and explained by scientonomy. Thus, we formulate a new law of theory demarcation to account for changes in scientificity within the scientonomic framework. (shrink)

Del Santo and Gisin have recently argued that classical mechanics exhibits a form of indeterminacy and that by treating the observables of classical mechanics with real number precision we introduce hidden variables that restore determinacy. In this article we introduce the conceptual machinery required to critically evaluate these claims. We present a characterization of indeterminacy which can capture both quantum indeterminacy and the classical indeterminacy of Del Santo and Gisin. This allows us to show that there is an important difference (...) in kind between the two: their classical indeterminacy can be resolved with hidden variables in a manner which is not possible for quantum indeterminacy.

Design plays an integral role in the functions of modern society. Yet the abstract process by which designers carry out their work is not obvious. The study of design thinking has grown in recent years into a major area of academic research, yet it presently lacks a clear theoretical basis; and as a discipline, its methodologies are disparate. Here, we outline and clarify the framework of the scholarly study of design thinking, introducing the major ideas and concepts upon which the (...) field is based. We then discuss in detail the various methodological issues of the field, and argue that, in its current state, the field of design thinking cannot sustain itself as an independent area of academic research. We suggest that design thinking may best be studied from a sociological or science, technology, and society (STS) studies perspective. (shrink)

Constructivist epistemology posits that all truths are knowable. One might ask to what extent constructivism is compatible with naturalized epistemology and knowledge obtained from inference-making using successful scientific theories. If quantum theory correctly describes the structure of the physical world, and if quantum theoretic inferences about which measurement outcomes will be observed with unit probability count as knowledge, we demonstrate that constructivism cannot be upheld. Our derivation is compatible with both intuitionistic and quantum propositional logic. This result is implied by (...) the Frauchiger-Renner theorem, though it is of independent importance as well.

The author discusses an inscription of the late fourth or early third century BC carved on a bronze plaque found in the first excavations at Dodona, on which a Zakynthian, by name Agathon, records a link of proxeny between himself and his family and the Epirote koinon of the Molossians, through Kassandra, the Trojan prophetess. The plaque is decorated by a prominent phallus with testicles, which the author interprets as referring to the continuity, past and future, of the "geneá" of (...) Agathon. Other explanations of the whole piece have been proposed, and the present essay is intended only to explore the possibility of this interpretation. (shrink)

The exclusive emphasis on academic excellence in our schools today does not necessarily translate into excellence of character or lend our students an ethical disposition. Thus, I include ethics instruction to young people who will one day become the citizens and leaders of tomorrow. Because ethics invokes questions that consider morals, values, and principles, and because it seeks to consider and respect alternate perspectives, I believe that ethics knowledge is essential to maintaining a civilized society. This essay will share some (...) of the philosophy and methods that I have used successfully with middle-level students (grades 5-8) to help them reflect upon what it means to be ethical human beings and good citizens—in addition to supporting their efforts to achieve academic excellence.

I. The present paper was read as one of ‘Three Notes of Doubt and One of Despair’ at the Oxford Philological Society in June 1948. Generally speaking, there is nothing to be said in favour of publishing an article on a text one is admittedly unable to under-stand. But in this case it has seemed advisable to start a discussion. I am therefore grateful to my friend P. Fraser for having consented to communicate his thoughts on the matter in an (...) appendix to my note. We both hope that other scholars will be able to provide the satisfactory solution that has escaped us. Meanwhile we thank P. Maas, C. H. Roberts, and H. M. Last for their great help. (shrink)
