Lemmon argues that dilemmas occur between classes of 'oughts;' duties, obligations, and moral principles. He claims that there are not conflicts within each class, presumably because he is a utilitarian, and thinks that moral principles will always be univocal.

A class of problems is called decidable if there is an algorithm which will give the answer to any problem of the class after a finite length of time. The purpose of this paper is to discuss the classes of problems that can be solved by infinitely long decision procedures in the following sense: An algorithm is given which, for any problem of the class, generates an infinitely long sequence of guesses. The problem will be said to be solved in (...) the limit if, after some finite point in the sequence, all the guesses are correct and the same. Functions, sets, and functionals which are decidable by such infinite algorithms will be calledlimiting recursive. These, together with classes of objects which can beidentified in the limit, are the subjects of this report.Without qualification,setwill mean set of numbers;functionwill mean number-theoretic function of 1 variable, possibly partial;functionalswill take numerical values and have any number of numerical and/or function variables, the latter ranging solely over total functions of 1 variable. Thus a function is a special case of a functional,xwill invariably stand for a numerical variable;φfor a function variable;gfor a guess ;nfor the numerical variable which indexes the guesses, referred to as thetime.

In The Form of Truth: Hegel’s Philosophical Logic, Elena Ficara offers a reappraisal of G.W.F. Hegel’s logic within the history of logic and in relation to the logics of today. She brings together...

A recent analysis by de Barros and Suppes of experimentally realizable GHZ correlations supports the conclusion that these correlations cannot be explained by introducing local hidden variables. We show, nevertheless, that their analysis does not exclude local hidden variable models in which the inefficiency in the experiment is an effect not only of random errors in the detector equipment, but is also the manifestation of a pre-set, hidden property of the particles ("prism models"). Indeed, we present an explicit prism model (...) for the GHZ scenario; that is, a local hidden variable model entirely compatible with recent GHZ experiments. (shrink)

The crisis of western civilization is a crisis of public philosophy. This is the charge of Public Philosophy and Political Science, a stunning new collection of essays edited by E. Robert Statham Jr. Vividly cataloging the decay of the moral and intellectual foundations of civic liberty, the book portrays a generation of Americans alienated from institutions built on public philosophy. The work exposes the failure of America's political scientists to acknowledge and understand this alarming crisis in the American body politic. (...) The distinguished contributors examine the evolution of public philosophy; the inextricable relationship between politics and philosophy; and the interplay between public philosophy, the constitution, natural law, and government. They reveal the dire threat to deliberative democracy and the fundamental order of constitutional society posed by public philosophy's waning power to refine, cultivate, and civilize. The work is an indictment of a society which has discarded a way of life rooted in natural law, democracy and the traditions of civility; and is a denunciation of an educated elite that has divorced itself from the standards upon which public philosophy rests. It is essential reading for philosophers and political and social scientists seeking to resurrect the standards of American public life. (shrink)
