A system of tensed intensional logic excluding iterations of intensions is introduced. Instead of using the type symbols (for ‘sense’), extensional and intensional functor types are distinguished. A peculiarity of the semantics is the general acceptance of value-gaps (including truth-value-gaps): the possible semantic values (extensions) of extensional functors are partial functions. Some advantages of the system (relatively to R. Montague's intensional logic) are briefly indicated. Also, applications for modelling natural languages are illustrated by examples.

According to Russell’s famous Gray’s Elegy argument within “On Denoting”, Frege’s distinction between Sinn and Bedeutung is problematic when applied to a denoting phrase like ‘the first line of Gray’s Elegy’, which denotes a linguistic expression: ‘The curfew tolls the knell of parting day’. The author shows that Russell’s Gray’s Elegy argument involves imprecision in the use of quotation marks as well as the unwarranted identification of an expression’s meaning with the expression itself.

Neuroenhancement involves the use of neurotechnologies to improve cognitive, affective or behavioural functioning, where these are not judged to be clinically impaired. Questions about enhancement have become one of the key topics of neuroethics over the past decade. The current study draws on in-depth public engagement activities in ten European countries giving a bottom-up perspective on the ethics and desirability of enhancement. This informed the design of an online contrastive vignette experiment that was administered to representative samples of 1000 respondents (...) in the ten countries and the United States. The experiment investigated how the gender of the protagonist, his or her level of performance, the efficacy of the enhancer and the mode of enhancement affected support for neuroenhancement in both educational and employment contexts. Of these, higher efficacy and lower performance were found to increase willingness to support enhancement. A series of commonly articulated claims about the individual and societal dimensions of neuroenhancement were derived from the public engagement activities. Underlying these claims, multivariate analysis identified two social values. The Societal/Protective highlights counter normative consequences and opposes the use enhancers. The Individual/Proactionary highlights opportunities and supports use. For most respondents these values are not mutually exclusive. This suggests that for many neuroenhancement is viewed simultaneously as a source of both promise and concern. (shrink)

Two books have been particularly influential in contemporary philosophy of science: Karl R. Popper's Logic of Scientific Discovery, and Thomas S. Kuhn's Structure of Scientific Revolutions. Both agree upon the importance of revolutions in science, but differ about the role of criticism in science's revolutionary growth. This volume arose out of a symposium on Kuhn's work, with Popper in the chair, at an international colloquium held in London in 1965. The book begins with Kuhn's statement of his position followed by (...) seven essays offering criticism and analysis, and finally by Kuhn's reply. The book will interest senior undergraduates and graduate students of the philosophy and history of science, as well as professional philosophers, philosophically inclined scientists, and some psychologists and sociologists.

Imre Lakatos' philosophical and scientific papers are published here in two volumes. Volume I brings together his very influential but scattered papers on the philosophy of the physical sciences, and includes one important unpublished essay on the effect of Newton's scientific achievement. Volume II presents his work on the philosophy of mathematics (much of it unpublished), together with some critical essays on contemporary philosophers of science and some famous polemical writings on political and educational issues. Imre Lakatos had (...) an influence out of all proportion to the length of his philosophical career. This collection exhibits and confirms the originality, range and the essential unity of his work. It demonstrates too the force and spirit he brought to every issue with which he engaged, from his most abstract mathematical work to his passionate 'Letter to the director of the LSE'. Lakatos' ideas are now the focus of widespread and increasing interest, and these volumes should make possible for the first time their study as a whole and their proper assessment. (shrink)

Proofs and Refutations is essential reading for all those interested in the methodology, the philosophy and the history of mathematics. Much of the book takes the form of a discussion between a teacher and his students. They propose various solutions to some mathematical problems and investigate the strengths and weaknesses of these solutions. Their discussion (which mirrors certain real developments in the history of mathematics) raises some philosophical problems and some problems about the nature of mathematical discovery or creativity. (...) class='Hi'>Imre Lakatos is concerned throughout to combat the classical picture of mathematical development as a steady accumulation of established truths. He shows that mathematics grows instead through a richer, more dramatic process of the successive improvement of creative hypotheses by attempts to 'prove' them and by criticism of these attempts: the logic of proofs and refutations.

Institutions are a kind of social infrastructure that facilitates – or hinders – human co-ordination and allocation of resources. Thus they function as a rationality context, which simultaneously emerges from and governs human interactions. Business institutions, as they are related to human expectations, should promote the values of their stakeholders and, consequently, they are subjects of social and ethical accounting, auditing and reporting procedures. Ethical institutions make the good of their stakeholder groups part of the institution’s own good. They have (...) a clear vision and picture of integrity throughout the institution which is owned and embodied by top management, over time. Such a practice presumes that business institutions, e.g. corporations, are social cultures with character, which can exercise good or bad influence, depending on goals, policies structures, strategies that formalize relations among the individuals who build up corporations. For developing an ethical culture, corporations need a large scale of instruments as codes of ethics and other kinds of support structures throughout the organization to insure their adequate communication, oversight, enforcement, adjudication, and review. Between all these instruments, a special role could be played by the ethics officer and the ethics committee, ethics trainings, ethics audits but also by the implementation of responsibility and participatory decision making at lower levels in the organisation.

The year 1996 was regarded by a considerable part of contemporary literature on global political economy as a definite turning point in modern history. The majority of experts tended to see the starting point of take‐off that year, but others—not a negligible minority—saw omens of disastrous recession and lasting depression. It appears the time has not yet come. The question is now that of the incalculable resultant of runaway (deregulated) forces of the international financial “whirlpool”, of a random process of (...) global, regional and local accumulation of capital. The year 1997 will set in with a foreseeable and calculable agrarian and related cycle and it may find an outlet for accumulated tensions of capital accumulation at the high tide of unemployment (demographic or migratory) wave with unforeseeable and incalculable effects and side‐effects. This will be just the beginning of the end and a Black Weekday still lies ahead of us. There can be no doubt that we live in a transition period but we do not know where this transition leads to. Loose talk about “post‐industrial society”, “post‐modern age” and “postsomething anything” has limited interpretative power. Very few students of social sciences venture to see and verify secular trends in world history. (shrink)
