We illustrate the application of the conceptual analysis (CA) method outlined in Part I by the example of quantum mechanics. In the present part the Hilbert space structure of conventional quantum mechanics is deduced as a consequence of postulates specifying further idealized concepts. A critical discussion of the idealizations of quantum mechanics is proposed. Quantum mechanics is characterized as a “statistically complete” theory and a simple and elegant formal recipe for the construction of the fundamental mathematical apparatus of quantum mechanics (...) is formulated. Our analysis may also lead to a criticism of quantum mechanics as a “strongly idealized” theory. A critical analysis of the fundamental structure of quantum mechanics seems an indispensable and natural starting point for the construction of new theories. A major technical problem in a more general application of the CA method is the lack of mathematical representation theorems for more general algebraic structures. (shrink)

The application of the conceptual analysis (CA) method outlined in Part I is illustrated on the example of quantum mechanics. In Part II, we deduce the complete-lattice structure in quantum mechanics from postulates specifying the idealizations that are accepted in the theory. The idealized abstract concepts are introduced by means of a topological extension of the basic structure (obtained in Part I) in accord with the “approximation principle”; the relevant topologies are not arbitrarily chosen; they are fixed by the choice (...) of the idealizations. There is a typical topological asymmetry in the mathematical scheme. Convexity or linear structures do not play any role in the mathematical methods of this approach. The essential concept in Part II is the idealization of “perfect measurement” suggested by our conceptual analysis in Part I. The Hilbert-space representation will be deduced in Part III. In our papers, we keep to the tenet: The mathematical scheme of a physical theory must be rigorously formulated. However, for physics, mathematics is only a nice and useful tool; it is not purpose.

A method is proposed that should facilitate the construction of theories of “submicroscopic particles” (denoted as “theories of microchannels”) in a way similar to the use of group-theoretical methods. The “conceptual analysis” (CA) method is based on the analysis of the basic concepts of a theory; it permits a determination of necessary conditions imposed on the mathematical apparatus (of the theory) which then appear as a mathematical representation of the structures obtained in a formal scheme of a theory. A pertinent (...) conceptual analysis leads to a new definition (“relativization”) of the concept “empirical implication.” The approach may be characterized as “realistic” and “operational.” The application of the CA method is illustrated on the example of quantum theory. In Part I the algebraic structure of a partially ordered, up-ward directed, bounded set is deduced from the rudimentary concepts. In Parts II and III, we shall deduce the Hilbert-space structure (well established in quantum mechanics) from postulates on some essential idealizations accepted in the theory. Whereas Part II is concerned with the idealizations of existing quantum theories based on the Hilbert-space formalism, Part I may be considered as a general basis for a wider class of theories.

Standard models of adolescent risk taking posit that the cognitive abilities of adolescents and adults are equivalent, and that increases in risk taking that occur during adolescence are the result of socio emotional differences in impulsivity, sensation seeking, and lack of self-control. Fuzzy-trace theory incorporates these socio emotional differences. However, it predicts that there are also cognitive differences between adolescents and adults, specifically that there are developmental increases in gist-based intuition that reflects understanding. Gist understanding, as opposed to verbatim-based analysis, (...) generally has been hypothesized to have a protective effect on risk taking in adolescence. Gist understanding is also an essential element of informed consent regarding risks in medical decision- making. Evidence thus supports the argument that adolescents’ status as mature minors should be treated as an exception rather than a presumption, because accuracy in verbatim analysis is not mature gist understanding. Use of the exception should be accompanied by medical experts’ input on the bottom-line gist of risks involved in treatment. (shrink)

Christology seems to fall fairly clearly into two divisions. The first is concerned with the truth of the two propositions: ‘Christ is God’ and ‘Christ is a man’. The second is concerned with the mutual compatibility of these propositions. The first part of Christology tends to confine itself to what is sometimes called ‘positive theology’: that is to say, it is largely given over to examining the Jons revelationis —let us not prejudge currently burning issues by asking what this is—to (...) see what evidence can be found for the truth of these propositions. Clearly, the methods used will be above all those of New Testament exegesis. The second part of Christology will necessarily consist entirely of that speculative theology which is contrasted with positive theology. Even if the earliest speculation on this topic is to be found in the New Testament itself and thus becomes fair game for the exegetes, any attempt to relate the primary truths, ‘Christ is God’ and ‘Christ is a man’, to eachother is a work of reflection, and in the terminology I am using speculative.

This volume presents twenty-two uncollected philosophical essays by Sir Peter Strawson, one of the leading philosophers of the second half of the twentieth century. The essays (two of them previously unpublished) are drawn from seven decades of work, from 1949 to 2003. They span the broad range of Strawson's work: metaphysics, epistemology, philosophical logic, philosophy of language, ethical theory, and history of philosophy, along with metaphilosophical reflections and intellectual autobiography.

In this important collection of essays Dennis Thompson argues for a more robust conception of responsibility in public life than prevails in contemporary democracies. He suggests that we should stop thinking so much about public ethics in terms of individual vices and start thinking about it more in terms of institutional vices. Combining theory and practice with many concrete examples and proposals for reform, these essays could be used in courses in applied ethics or political theory and will be read (...) by professionals and graduate students in schools of political science, public policy, law, public health, journalism and business.

Whoever hesitates to utter that which he thinks the highest truth, lest it should be too much m advance of the time, may reassure himself by looking at his act DEGREES from an impersonal point of view.... It is not for nothing that he has in him these sympathies with some principles and repugnance to others. He, with all his capacities, and aspirations, and beliefs, is not an accident, but a product of the time. He must remember that while he (...) is a descendant of the past he is a parent of the future; and that his thoughts are as children born to him, which he may not carelessly let die. Herbert S.

In Morals By Agreement, David Gauthier concludes that under certain conditions it is rational for an agent to be disposed to choose in accordance with a fair cooperative scheme rather than to choose the course of action that maximizes his utility. This is only one of a number of important claims advanced in that book. In particular, he also propounds a distinctive view concerning what counts as a fair cooperative arrangement. The thesis concerning the rationality of adopting a cooperative disposition (...) is, however, logically independent of his substantive view of a fair cooperative scheme and is itself central to the project as a whole. Gauthier's concern is to establish that certain moral principles are those that fully rational, self-interested persons would agree to take as regulative of their dealings with one another – that a contractarian approach, in this sense, can provide an adequate basis for a theory of morality.

G. W. F. Hegel is an immensely important yet difficult philosopher. Philosophy of Mind is the third part of Hegel's Encyclopaedia of the Philosophical Sciences, in which he summarizes his philosophical system. It is one of the main pillars of his thought. Michael Inwood presents this central work to the modern reader in an intelligible and accurate new translation---the first into English since 1894---that loses nothing of the style of Hegel's thought. In his editorial introduction Inwood offers a philosophically sophisticated (...) evaluation of Hegel's ideas which includes a survey of the whole of Hegel's thought and detailed analysis of the terminology he used.

In a discussion-note in Mind, Father P. M. Farrell, O.P., gave an account, in what he admitted to be an embarrassingly brief compass, of the Thomist doctrine concerning evil. There is one sentence in this discussion which at first glance appears paradoxical. Father Farrell has been arguing that a universe containing ‘corruptible good’ as well as incorruptible is better than one containing ‘incorruptible good’ only. He continues: ‘If, however, they are to manifest this corruptible good, they must be corruptible and (...) they must sometimes corrupt.’ The final words, despite Father Farrell's italics, strike one as expressing, not a self-evident truth, but a non sequitur. The fact that I am capable of committing murder does not entail that I will at some time commit it. It is not immediately obvious that a similar entailment holds in the case of corruption and corruptibility. (shrink)

First published in 1931 and originally delivered as the Deems Lectures at New York University in 1929, this book examines what scientific discoveries in many different branches of science reveal, and the implications of such discoveries for philosophy. Esteemed philosopher F. S. C. Northrop surveys a variety of advances, including relativity and quantum mechanics, and how they correlate to his epistemological theory of concepts. This book will be of value to anyone with an interest in the history of science and (...) the connection between science and philosophy. (shrink)

In Practicing Safe Sects F. LeRon Shults provides scientific and philosophical resources for having “the talk” about religious reproduction: where do gods come from – and what are the costs of bearing them in our culturally pluralistic, ecologically fragile environment?
