We analyze recent criticisms of the use of hyperreal probabilities as expressed by Pruss, Easwaran, Parker, and Williamson. We show that the alleged arbitrariness of hyperreal fields can be avoided by working in the Kanovei–Shelah model or in saturated models. We argue that some of the objections to hyperreal probabilities arise from hidden biases that favor Archimedean models. We discuss the advantage of the hyperreals over transferless fields with infinitesimals. In Paper II we analyze two underdetermination theorems by Pruss and (...) show that they hinge upon parasitic external hyperreal-valued measures, whereas internal hyperfinite measures are not underdetermined.

ABSTRACTA probability model is underdetermined when there is no rational reason to assign a particular infinitesimal value as the probability of single events. Pruss claims that hyperreal probabilities are underdetermined. The claim is based upon external hyperreal-valued measures. We show that internal hyperfinite measures are not underdetermined. The importance of internality stems from the fact that Robinson’s transfer principle only applies to internal entities. We also evaluate the claim that transferless ordered fields may have advantages over hyperreals in probabilistic modeling. (...) We show that probabilities developed over such fields are less expressive than hyperreal probabilities. (shrink)

We present an ontological analysis of the notion of group agency developed by Christian List and Philip Pettit. We focus on this notion as it allows us to neatly distinguish groups, organizations, corporations – to which we may ascribe agency – from mere aggregates of individuals. We develop a module for group agency within a foundational ontology and we apply it to organizations.

1 Introduzione La Fiorentina è una squadra di calcio dalla vita ultimamente piuttosto travagliata. Maurizio Ferraris, citando un’acuta osservazione di un suo studente, dà un’interessante descrizione di questa sua complicata esistenza: L’ac Fiorentina, nata il 26 agosto 1926, fallisce nel luglio 2002, e cessa ufficialmente di esistere. Una nuova società, la Florentia Viola, nasce il 3 agosto 2002, all’indomani della mancata iscrizione al campionato di serie B della ac Fiorentina 1926, e prende...

We thank Chiara Bassetti, Emanuele Bottazzi and the journal Etnografia e Ricerca Qualitativa for the permission to republish it. But, friend, when you grasp the number and nature of the intervals of sound, from high to low, and the boundaries of those intervals, and how many scales arise from them, (...) - Anthropologie – Nouvel article.
