The Origin of Speciesism

Anti-vivisectionists charge that animal experimenters are speciesists—people who unjustly discriminate against members of other species. Until recently most defenders of experimentation denied the charge. After the publication of The Case for the Use of Animals in Biomedical Research in the New England Journal of Medicine, experimenters had a more aggressive reply: I am a speciesist. Speciesism is not merely plausible, it is essential for right conduct .... Most researchers now embrace Cohens response as part of their defense of animal experimentation. Cohen asserts that both rights and utilitarian arguments

Animal Experimentation: the legacy of Claude Bernard

Abstract Claude Bernard, the father of scientific physiology, believed that if medicine was to become truly scientific, it would have to be based on rigorous and controlled animal experiments. Bernard instituted a paradigm which has shaped physiological practice for most of the twentieth century. In this paper we examine how Bernards commitment to hypothetico‐de‐ductivism and determinism led to (a) his rejection of the theory of evolution; (b) his minimalization of the role of clinical medicine and epidemiological studies; and (c) his conclusion that experiments on non‐human animals were, “entirely conclusive for the toxicology and hygiene of man”. We examine some negative consequences of Bernardianism for twentieth century medicine, and argue that physiologys continued adherence to Bernardianism has caused it to diverge from the other biological sciences which have become increasingly infused with evolutionary theory.

Modeling Biological Systems: The Belousov–Zhabotinsky Reaction

In this essay I examine the ways in which the Belousov–Zhabotinsky (BZ) reaction is being used by biologists to model a variety of biological systems and processes. The BZ reaction is characterized as a functional model of biological phenomena. It is able to play this role because, though based on very different substrates, the model and system modeled are examples of the same type of excitable medium. Lessons are drawn from this case about the relationships between the sciences of chemistry and biology.

Axiomatic quantum mechanics and radioactive decay

This paper explores the consequences of the orthodox resolution of the measurement problem for the axiomatic base of non-relativistic elementary quantum mechanics. It is argued that the standard resolution of the measurement problem generates a paradox whose dissolution may be achieved through an enrichment of the axiomatic foundations of quantum mechanics. These results are also linked to some recent creative proposals by Nancy Cartwright concerning the nature of the so-called “reduction of the wave packet”.

Time and the propensity interpretation of probability

SummaryThe prime concern of this paper is with the nature of probability. It is argued that questions concerning the nature of probability are intimately linked to questions about the nature of time. The case study here concerns the single case propensity interpretation of probability. It is argued that while this interpretation of probability has a natural place in the quantum theory, the metaphysical picture of time to be found in relativity theory is incompatible with such a treatment of probability.
