Subjective Probability: The Real Thing is the last book written by the late Richard Jeffrey, a key proponent of the Bayesian interpretation of probability. Bayesians hold that probability is a mental notion: saying that the probability of rain is 0.7 is just saying that you believe it will rain to degree 0.7. Degrees of belief are themselves cashed out in terms of bets— in this case you conside...

1 This is an expanded rewriting of a paper presented to a conference on " Austrian Thought at the Turn of the Twentieth Century " in November 2012, at the University of Texas at Arlington, organized by Professor Gloria Zuniga Postigo, of the Department of Philosophy and Humanities at that university. My thanks go to her for the generous invitation and to the participants of the conference for p...

This paper critically analyses the strongly subjectivist approach to exploitation theory recently proposed by Matsuo ([7]), in the context of general convex economies with heterogeneous agents. It is proved that the Fundamental Marxian Theorem is not preserved in his subjectivist approach, contrary to Matsuo’s claims, and that no meaningful subjectivist exploitation index can be constructed. It...

Although the necessity of building models seems obvious, it is astonishing that only few works deal with fundamental problems how models need to be understood from an epistemological point of view (e.g.: how does a modeler come to a model; why and in which ways do models built by different designers differ from another). The paper bases on the assumption that the subjective position of the mode...

This thesis examines the philosophical background that culminates in the Austrian School of economics' theories of capital and interest. In chapter two, I describe the character of the school, its history, and the educational, environmental and social background of the main authorities. The school is characterised by an adherence to Carl Menger's doctrines, with Eugen von Böhm-Bawerk, Friedrich...

The life sciences are rife with probabilistic generalizations. Mendel (1865) discovered that the chance of a hybrid green and yellow pea plant to produce yellow peas in the F2 generation is .75. In neuroscience, the release of neurotransmitters can fail to result in the successful initiation of electrical activity in a particular postsynaptic neuron up to 90% of the time (Kandel et al. 2013, 27...

This is a remarkable volume. Winner of the Lakatos award, given biennially for the book in the philosophy of science most highly regarded by an international committee, it is also crammed with formulas that will be of practical importance, as well as of interest, to epidemiologists, lawyers, economists, and other down-to-earth folk. This is not to say that it will be easy to read, for anyone, o...
