The past decade has seen notable development of conceptual engineering – a field of analytical philosophy that focuses on the critical evaluation of concepts. Most authors engaged with this area identify Rudolf Carnap’s ideas as its methodological framework and theoretical origin, placing particular emphasis on the philosopher’s method of explication. This article highlights the unquestionable influence Carnap’s thought had on conceptual engineering whilst by no means reducing it to the utilisation and advancement of explication within this field of analytical philosophy: (...) indeed, conceptual engineering has incorporated – and brought to the forefront – much broader tenets of Carnap’s concept. This study draws on a series of the philosopher’s works, as well as his ‘Intellectual Autobiography’, to trace the evolution of his ideas about language and describe the fundamental elements revealing the ‘engineering perspective’ in his reflection. Most clearly, this perspective is evident in his interpretation of logic as a conceptual tool for acquiring and processing knowledge, ‘assembling’ it into a structure and refining the procedures of logic itself. It is shown that the origins of the engineering perspective trace back, on the one hand, to Carnap’s interest in the methodological framework of physics, particularly the measurement problem and its epistemological analysis, and, on the other, his fascination with interpretations of the nature of mathematical theory and the idea of unifying logicism and formalism by introducing the principle of tolerance, which adds a pragmatic dimension to methodology. The article examines in detail the idea of explication and its theoretical origins, which lie, in particular, in Carnap’s intention to exactify the notions expressing the degree of validity and probability. His idea of a link between the results of explication and its goal became the central principle of conceptual engineering, distinguishing it from mere conceptual analysis. It is concluded that, when considered together, Carnap’s two major ideas – explication and the principle of tolerance – can be placed in a broader context of a project seeking a rational reconstruction of the life of society and providing it with knowledge-based underpinnings.

O'Hagan agrees with Dent that in Rousseau's idea of "amour-propre" we encounter a powerful, coherent model of human psychology, according to which individuals find their own identities by engaging in a network of relationships within a more or less reconstituted social order. He examines five ways in which people strive to attain that goal and five ways in which they characteristically fail. In the sixth section he discusses Rousseau's strategy of retreat from society, which is also a retreat from the (...) demands of "amour-propre". (shrink)

Diodorus' Master Argument was intended to show that whatever is possible either is or will be true. The intended conclusion does not follow from the extant premisses of the Master Argument. The Near Miss argues however, from those premisses alone, that nothing can be more than momentarily an exception to the Master Argument's intended conclusion. Strong arguments support even the most contentious of those premisses . We therefore cannot easily ignore the Near Miss. Moreover, there are various supplementary premisses that (...) would turn the Near Miss into an argument with the full force of the Master Argument itself. Each of Diodorus' ancient rivals, since they accepted such doctrines as eternal recurrence, temporal atomism, and the "extended" present, would grant him at least one of these supplementary premisses. So too would any modern who holds that time is not circular, has no beginning, and does not branch. (shrink)

According to familiar accounts, Rousseau held that humans are actuated by two distinct kinds of self love: amour de soi, a benign concern for one's self-preservation and well-being; and amour-propre, a malign concern to stand above other people, delighting in their despite. I argue that although amour-propre can assume this malign form, this is not intrinsic to its character. The first and best rank among men that amour-propre directs us to claim for ourselves is that of occupying 'man's estate'. This (...) does not require, indeed it precludes, subjection of others. Amour-propre does not need suppression or circumscription if we are to live good lives; it rather requires direction to its proper end, not a delusive one. (shrink)

Liberal critics of plato's republic criticise him for ignoring the moral autonomy of persons, their right to form and to express their own moral ideas. It is argued that this criticism is superficial. Neither plato, nor his liberal critics, wish all moral views to be held and acted on; they both wish to set limits to what is acceptable. The true source of disagreement is over the scope of reason in human affairs; plato understands that narrowly; his liberal critics in (...) a broad, permissive, way. (shrink)

This note discusses critically a point in a d m walker's paper "the ideal of sincerity" ("mind", October 1978). Walker claims that desires are insincere if corrupted by incompatible desires. This view accounts for some cases, But not for all. It is argued, In the note, That superficial, Factitious, 'got up' desires are judged insincere as such because not 'natural' to a man. This is implied by the claim of andre gide's which walker misinterprets. The issue of natural desires in (...) contrast to artificial desires introduces the question of 'authenticity', Which is looked at in connection with lionel trilling's "sincerity and authenticity".

"This volume is concerned with how we ought to evaluate the individual and collective actions on which the existence, numbers and identities of future people depend - discussed here as the "problem of contingent future persons." For it seems that those future persons who are brought into existence by such actions cannot benefit from or be harmed by them in any conventional sense. This is a relatively novel problem in ethics and as yet there is simply no consensus on how (...) we ought to evaluate such actions or, indeed, on whether we can. However, the pursuit of a solution to the problem has been interestingly employed by moral philosophers to press the limits of ethics and to urge a reconsideration of the nature and source of value at its most fundamental level. Intended for professional ethicists, policy researchers, and graduate students, this volume explores the theological implications of the problem and advances the investigation of it both philosophical and in theological terms." --Book Jacket.

Context: Immunity includes cognitive concepts: the organism is thought to specifically recognize foreign materials and develop a memory of these encounters. Vaccines are thought to work by enhancing this immunological memory. Lymphocytes are key cells and specific antibodies are key molecules in immune recognition. Antibodies are blood proteins called “immunoglobulins.” Spontaneously formed immunoglobulins are seen as “natural” antibodies to dietary components and commensal bacteria. Immune cognition is used simply as a didactic metaphor. Problem: Do the cognitive aspects of immunology stem (...) from the activities of cells and molecules, or are they ascribed by the immunologist operating as a human observer? (1) An immense variety of immunoglobulins may bind to the same antigen with different binding energies. It is the immunologist who arbitrates the boundary between those that are specific (and declared antibodies) and those that are not. Specific antibodies serve as functional labels pasted onto natural immunoglobulins, as if they were recognizing elements. Is this “arbitration” the true cognitive event ascribed to immunoglobulins and lymphocytes? (2) A major impasse exists between progress in experimental immunology and its translation into clinical results. A proper understanding of immunological activity demands a wider view of an organism’s biology and, also, of the interference of human observers in delineating experimental realities, such as the specificity of immune recognition. Maturana’s biology of cognition and language provides one such approach. Method: Use of Maturana’s biology of cognition and language concepts to describe immunological activity. Results: A whole new understanding of immunological activity is suggested. Implications: A major change in the way of seeing is proposed that may eventually help the translation of this knowledge into clinical results. Furthermore, the immune system may also become a proper model for cognitive analyses. (shrink)

For a subset K ⊆ [0, 1], the notion of K-satisfiability is a generalization of the usual satisfiability in first order fuzzy logics. A set Γ of closed formulas in a first order language τ is K-satisfiable, if there exists a τ-structure such that ∥ σ ∥ ∈ K, for any σ ∈ Γ. As a consequence, the usual compactness property can be replaced by the K-compactness property. In this paper, the K-compactness property for Łukasiewicz first order logic is investigated. (...) Using the ultraproduct construction, it is proved that for any closed subset K and set Γ of closed formulas, Γ is K-satisfiable if and only if it is finitely K-satisfiable. (shrink)
