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.

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; II—Criticism and the Methodology of Scientific Research Programmes, Proceedings of the Aristotelian Society, Volume 69, Issue 1, 1 June 1969, Page.

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his very influential but scattered papers on the philosophy of the physical sciences, and includes one important unpublished essay on the effect of Newton's scientific achievement. Volume 2 presents his work on the philosophy of mathematics (much of it unpublished), together with some critical essays on contemporary philosophers of science and some famous polemical writings on political and educational issues.

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)

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.

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)

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 raises some philosophical problems and some problems about the nature of mathematical discovery or creativity. 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.

This paper suggests that the classic of Indian theology, the Nyāya-kusumâñjali is in fact two texts: an earlier treatise in 65 ślokas, and Udayana’s commentary on it. Internal evidence consists in: the ślokas read as a continuous text; there are extremely long prose passages without verses; Udayana does not comment on his own verses, only on the ślokas; the basic plan of the two texts are markedly different; different content of some chapters: ch. 1 about karma vs. rituals to reach (...) heaven, ch. 2 about creation vs. eternality of sound, and in ch. 5 Udayana doubles the arguments for God; Udayana deals extensively with atoms and yogic perception and rejects the concept of śakti, in contrast to the verses; there are a few manifest disagreements. External evidence for the thesis: there are mss. of the verses only; there are many commentaries on the verses only; these commentators—with a single exception—do not seem to take Udayana for the author of the verses; the first commentary on Udayana names his own work a subcommentary; in his other works, it is atypical of Udayana to insert ślokas in his text; a legend of the Bhāduṙī Brahmins stating that Udayana “received” the Kusumâñjali.
