The examples and concepts that Shoemaker cites are rather heterogeneous. Some distinctions need to be drawn. An optimality thesis involves not just an ordering of options, but a value judgment about them. So let us begin by distinguishing minimality from optimality. And the concept of minimality can play a variety of roles, among which I distinguish between extremum descriptions, statements hypothesizing an optimizing process, and methodological recommendations. Finally, I consider how the three categories relate to Shoemaker’s question that “Who is (...) optimizing: the scientist or nature?” . (shrink)

This paper examines the strengths and weaknesses of one of science's most pervasive and flexible metaprinciples;optimalityis used to explain utility maximization in economics, least effort principles in physics, entropy in chemistry, and survival of the fittest in biology. Fermat's principle of least time involves both teleological and causal considerations, two distinct modes of explanation resting on poorly understood psychological primitives. The rationality heuristic in economics provides an example from social science of the potential biases arising from the extreme flexibility of (...) optimality considerations, including selective search for confirming vidence, ex post rationalization, and the confusion of prediction with explanation. Commentators are asked to reflect on the extent to which optimality is an organizing principle of nature, a set of relatively unconnected techniques of science, a normative principle for rational choice and social organization, a metaphysical way of looking at the world, or something else still.

Growing public interest in the dark arts, and the fact that even some philosophers have been accused of casting spells with their own writings, suggest that philosophers should not wholly neglect the topics of spells and spell-breaking. In this paper, written in honor of an effective spell-breaker in social and leadership contexts, Fr Theodore Vitali, I set out a taxonomy of spells and ways in which some philosophers may be said to cast them in a naturalistic sense. I also examine (...) ways of breaking a spell, with reference to the will and second-person relationship. I conclude with a brief observation about the desire for intellectual completeness, the root of a disordered appeal of at least some spells to their victims, suggesting an alternative scenario for a good satisfaction of this desire.

A comment on Paul Schoemaker's target article in Behavioral and Brain Sciences, 14 (1991), p. 205-215, "The Quest for Optimality: A Positive Heuristic of Science?" (https://doi.org/10.1017/S0140525X00066140). This comment argues that the optimizing model of decision leads to an infinite regress, once internal costs of decision (i.e., information and computation costs) are duly taken into account.

Once a name to conjure with, Scottish idealist James Frederick Ferrier (1808–1864) is now a largely forgotten figure, notwithstanding the fact that he penned a work of remarkable power and originality: the Institutes of Metaphysic (1854). In ‘Reid and the Philosophy and Common Sense,’ an essay of 1847 which anticipates some of the central themes of the Institutes of Metaphysic, Ferrier presents an excoriating critique of Thomas Reid's brand of common sense realism. Understanding Ferrier's critique of Reid – its content, (...) motivations, and significance – is the task of the present essay. (shrink)

The paper discusses some aspects of the relationship between Feyerabend and Kuhn. First, some biographical remarks concerning their connections are made. Second, four characteristics of Feyerabend and Kuhn's concept of incommensurability are discussed. Third, Feyerabend's general criticism of Kuhn's Structure of Scientific Revolutions is reconstructed. Forth and more specifically, Feyerabend's criticism of Kuhn's evaluation of normal science is critically investigated. Finally, Feyerabend's re-evaluation of Kuhn's philosophy towards the end of his life is presented.
