Recent years have been blessed with an abundance of logical systems, arising from a multitude of applications. A logic can be characterised in many different ways. Traditionally, a logic is presented via the following three components: 1. an intuitive non-formal motivation, perhaps tie it in to some application area 2. a semantical interpretation 3. a proof theoretical formulation. There are several types of proof theoretical methodologies, Hilbert style, Gentzen style, goal directed style, labelled deductive system style, and so on. The (...) tableau methodology, invented in the 1950s by Beth and Hintikka and later per fected by Smullyan and Fitting, is today one of the most popular, since it appears to bring together the proof-theoretical and the semantical approaches to the pre of a logical system and is also very intuitive. In many universities it is sentation the style first taught to students. Recently interest in tableaux has become more widespread and a community crystallised around the subject. An annual tableaux conference is being held and proceedings are published. The present volume is a Handbook a/Tableaux pre senting to the community a wide coverage of tableaux systems for a variety of logics. It is written by active members of the community and brings the reader up to frontline research. It will be of interest to any formal logician from any area. (shrink)

Plotinus is the first Greek philosopher to hold a systematic theory of consciousness. The key feature of his theory is that it involves multiple layers of experience: different layers of consciousness occur in different levels of self. This layering of higher modes of consciousness on lower ones provides human beings with a rich experiential world, and enables human beings to draw on their own experience to investigate their true self and the nature of reality. This involves a robust notion of (...) subjectivity. However, it is a notion of subjectivity that is unique to Plotinus, and remarkably different from the Post-Cartesian tradition. Behind the plurality of terms Plotinus uses to express consciousness, and behind the plurality of entities to which Plotinus attributes consciousness, lies a theory of human consciousness. It is a Platonist theory shaped by engagement with rival schools of ancient thought. (shrink)

The role of a functionalist account of phenomenal properties in Keith Frankish's illusionist position results in two issues for his view. The first concerns the ontological status of illusions of phenomenality. Illusionists are committed to their existence, and these illusions would appear to have phenomenal features. Frankish argues that functionalism about phenomenal properties yields a response, but I contend that it doesn't, and that instead the illusionist's basic account of phenomenal properties must be reapplied to the illusions themselves. The second (...) concern is that phenomenal properties would seem to be intrinsic properties of experience, but functionalism has them consist solely in relations. The nonfunctionalist option can recapture the sense that these properties are intrinsic. It can also preserve the intuition that they are causal powers in a robust sense, and thereby, perhaps surprisingly, provide a stronger response to the knowledge and conceivability arguments.

At the earliest break of ancient hominins from their primate relatives in vocal communication, we propose a selection pressure on vocal fitness signaling by hominin infants. Exploratory vocalizations, not tied to expression of distress or immediate need, could have helped persuade parents of the wellness and viability of the infants who produced them. We hypothesize that hominin parents invested more in infants who produced such signals of fitness plentifully, neglecting or abandoning them less often than infants who produced the sounds (...) less frequently. Selection for such exploratory vocalization provided a critically important inclination and capability relevant to language, we reason, because the system that encouraged spontaneous vocalization also made vocalization functionally flexible to an extent that has not been observed in any other animal. Although this vocal flexibility did not by itself create language, it provided an essential foundation upon which language would evolve through a variety of additional steps. In evaluating this speculation, we consider presumable barriers to evolving language that are thought to be implications of Darwinian Theory. It has been claimed that communication always involves sender self-interest and that self-interest leads to deceit, which is countered through clever detection by receivers. The constant battle of senders and receivers has been thought to pose an insuperable challenge to honest communication, which has been viewed as a requirement of language. To make communication honest, it has been proposed that stable signaling requires costly handicaps for the sender, and since language cannot entail high cost, the reasoning has suggested an insurmountable obstacle to the evolution of language. We think this presumed honesty barrier is an illusion that can be revealed by recognition of the fact that language is not inherently honest and in light of the distinction between illocutionary force and semantics. Our paper also considers barriers to the evolution of language (not having to do with honesty) that we think may have actually played important roles in preventing species other than humans from evolving language.

From the first months of life, human infants produce “protophones,” speech-like, non-cry sounds, presumed absent, or only minimally present in other apes. But there have been no direct quantitative comparisons to support this presumption. In addition, by 2 months, human infants show sustained face-to-face interaction using protophones, a pattern thought also absent or very limited in other apes, but again, without quantitative comparison. Such comparison should provide evidence relevant to determining foundations of language, since substantially flexible vocalization, the inclination to (...) explore vocalization, and the ability to interact socially by means of vocalization are foundations for language. Here we quantitatively compare data on vocalization rates in three captive bonobo (Pan paniscus) mother–infant pairs with various sources of data from our laboratories on human infant vocalization. Both humans and bonobos produced distress sounds (cries/screams) and laughter. The bonobo infants also produced sounds that were neither screams nor laughs and that showed acoustic similarities to the human protophones. These protophone-like sounds confirm that bonobo infants share with humans the capacity to produce vocalizations that appear foundational for language. Still, there were dramatic differences between the species in both quantity and function of the protophone and protophone-like sounds. The bonobo protophone-like sounds were far less frequent than the human protophones, and the human protophones were far less likely to be interpreted as complaints and more likely as vocal play. Moreover, we found extensive vocal interaction between human infants and mothers, but no vocal interaction in the bonobo mother–infant pairs—while bonobo mothers were physically responsive to their infants, we observed no case of a bonobo mother vocalization directed to her infant. Our cross-species comparison focuses on low- and moderate-arousal circumstances because we reason the roots of language entail vocalization not triggered by excitement, for example, during fighting or intense play. Language appears to be founded in flexible vocalization, used to regulate comfortable social interaction, to share variable affective states at various levels of arousal, and to explore vocalization itself.

Dowsing, water-witching, divining – the procedure seeks a flow or spring beneath the surface of earth. So too this inquiry attempts to locate and sound the meanings associated with the polestar of Thalean considerations, ὕδωρ, that course beneath the interpretative strata of an overly-familiar tradition grounded in the principles of clarity and intelligibility. If these principles are held in suspension, what meanings flow from the Thalean considerations of ὕδωρ? A twofold task guides this inquiry. First is to show opacity as (...) the primary valence of ὕδωρ, challenging the prevailing tendency to imagine Thales and other Milesian thinkers as positing a principle of clarity in the form of what can be brought under the Aristotelean concept of underlying thing and matter. Second, in the course of drawing up the opacity of ὕδωρ form varied archaic sources emerge some connections to important terms for Greek thinking: φύσις, λόγος, ἀλήθεια. (shrink)

Originally published in 1972, this book is a systematic analysis of the objectives and methods of history teaching. The book considers the criticisms of the 1960s and 70s of history as a subject and the pressures for its replacement in the school curriculum. It examines the complex psychological background of learning history and suggests that historical understanding makes an important contribution to cognitive growth. It also stresses the important part played by historical material in the emotional and imaginative life of (...) the child. Concluding with a discussion of practical classroom methods, the author proposes objectives and characteristic concepts of the subject which may be embodied in all levels of teaching. (shrink)
