In recent years new findings in vertebrate neuroanatomy have challenged received views on the evolution of the brain. Established theories suggesting that new structures are added to older structures or that old structures are modified into new ones are being re-evaluated. Modification processes, such as invasion and parcellation, have proved to be less valid than originally assumed. Discoveries of neuroanatomical homologies add to the cladistic interpretation problems.

It was not long ago when the consciousness was not considered a problem for science. However, this has now changed and the problem of consciousness is considered the greatest challenge to science. In the last decade, a great number of books and articles have been published in the field, but very few have focused on the how consciousness evolves and develops, and what characterizes the transitions between different conscious states, in animals and humans. This book addresses these questions. Renowned researchers (...) from different fields of science (including neurobiology, evolutionary biology, ethology, cognitive science, computational neuroscience and philosophy) contribute with their results and theories in this book, making it a unique collection of the state-of-the-art of this young field of consciousness studies. - First book on the topic - Focus on different levels of consciousness, including: Evolutionary, developmental, and functional - Highly interdisciplinary.

This article examines three aspects of the problem of understanding Benjamin Libet’s idea of conscious will causally interacting with certain neural activities involved in generating overt bodily movements. The first is to grasp the notion of cause involved, and we suggest a definition. The second is to form an idea of by what neural structure(s) and mechanism(s) a conscious will may control the motor activation. We discuss the possibility that the acts of control have to do with levels of supplementary (...) motor area activity and with the activation of populations of excitatory and inhibitory interneurons. The third aspect is to conceive of the main features of Libet’s proposed conscious mental field (CMF). We consider both an ontological and an epistemological interpretation of the CMF being nonphysical. In an attempt to refute the idea that Libet’s dualist mind–brain interactionism would violate the law of conservation of energy, we suggest that a CMF may alter the probability of the ion-channel gating by influencing structures of a size to which quantum mechanics needs to be applied. We argue that given the suggested definition of cause, and given the epistemological interpretation of the CMF being nonphysical, nothing would necessarily rule out that an element of a CMF, conscious will, may causally interact with neural activities in the brain. This defense of the idea of conscious will being causally efficacious has a bearing not only on the understanding of the mind–brain relation but also on the free will debate. (shrink)

The main objective of this essay is to validate some of the principal, currently competing, mammalian consciousness-brain theories by comparing these theories with data on both cognitive abilities and brain organization in birds. Our argument is that, given that multiple complex cognitive functions are correlated with presumed consciousness in mammals, this correlation holds for birds as well. Thus, the neuroanatomical features of the forebrain common to both birds and mammals may be those that are crucial to the generation of both (...) complex cognition and consciousness. The general conclusion is that most of the consciousness-brain theories appear to be valid for the avian brain. Even though some specific homologies are unresolved, most of the critical structures presumed necessary for consciousness in mammalian brains have clear homologues in avian brains. Furthermore, considering the fact that the reptile-bird brain transition shows more structural continuity than the stem amniote-mammalian transition, the line drawn at the origin of mammals for consciousness by several of the theorists seems questionable. An equally important point is that consciousness cannot be ruled out in the absence of complex cognition; it may in fact be the case that consciousness is a necessary prerequisite for complex cognition.

We show that many large cardinal notions up to measurability can be characterized through the existence of certain filters for small models of set theory. This correspondence will allow us to obtain a canonical way in which to assign ideals to many large cardinal notions. This assignment coincides with classical large cardinal ideals whenever such ideals had been defined before. Moreover, in many important cases, relations between these ideals reflect the ordering of the corresponding large cardinal properties both under direct (...) implication and consistency strength.

In Navigating Everyday Life, Peter Adams explores the moments when everyday experience seems to open up spaces beyond what we normally experience. Adams draws on two philosophical concepts: finitude, the things that bind a person to a situation, and transcendence, the things that lie beyond these boundaries.

End-of-life issues and questions are complex and frequently cause confusion and anxiety. In _Death with Dignity_,_ _theologian, medical ethicist, and pastoral caregiver Peter A. Clark examines numerous issues that are pertinent to patients, family members, and health care professionals, including physiology, consciousness, the definition of death, the distinction between extraordinary and ordinary means, medical futility, “Do Not Resuscitate” orders, living wills, power of attorney, pain assessment and pain management, palliative and hospice care, the role of spirituality in end-of-life care, (...) and physicians’ communication with terminal patients. Patients, family members, medical students, and health care professionals will find in _Death with Dignity _the_ _practical and ethical knowledge they need to capably and confidently cope with end-of-life challenges.

Peter Gärdenfors has developed a semantics for conditional logic, based on the operations of expansion and revision applied to states of information. The account amounts to a formalisation of the Ramsey test for conditionals. A conditional A > B is declared accepted in a state of information K if B is accepted in the state of information which is the result of revising K with respect to A. While Gärdenfors's account takes the truth-functional part of the logic as given, (...) the present paper proposes a semantics entirely based on epistemic states and operations on these states. The semantics is accompanied by a syntactic treatment of conditional logic which is formally similar to Gentzen's sequent formulation of natural deduction rules. Three of David Lewis's systems of conditional logic are represented. The formulations are attractive by virtue of their transparency and simplicity. (shrink)

Peter Boettke's Why Perestroika Failed offers an overly mechanistic explanation for the collapse of the Soviet economy, derived from Mises's theory of the economic impossibility of socialism. Arguing that the economic system was doomed to fail does not explain why it fell precisely when it did. Thus, Boettke underestimates the extent to which elements of the Communist nomenklatura themselves came to realize that their interests could be served by ditching the command economy. Such an emphasis on the role of (...) human agents is surely compatible with a Hayekian approach. (shrink)

A photographer and a geographer explore where the pavement ends. Nevada's enigmatic Black Rock country, despite its apparent silence and isolation, is actually an area where natural forces are ceaselessly restless and life in many forms has endured for millennia. Its haunting landscape has been the focus of study and contemplation by scientists, explorers, outdoors aficionados, and artists. In ""Black Rock,"" photographer Peter Goin and geographer Paul F. Starrs explore this fascinating place from the viewpoints of their respective disciplines. (...) The Black Rock, a desert realm almost the size of Delaware but scarcely a hundred miles north of Reno, embraces mile-high vertical mountains and one of the earth's flattest, most barren salt pans, boiling hot springs and freezing winter cold, plants that have evolved to survive the severest drought and lush pockets of rich grasses. Its bewildering environments startle our senses with a raw physical intensity that comes through in Goin's eloquent photographs and Starrs's richly informed text. We observe the region from numerous perspectives - the Black Rock at ground level, from the skies above, in the geology below; witness the shaping roles of water, wind, and geothermal action in shaping it; and view the effects of human hands, from ancient Native Americans to nineteenth-century explorers, ranchers, and miners, up through the congregants at today's Burning Man festivals. The result is a brilliant duet of visual and literary commentary on a region of stunning paradoxes and constant change and activity, where need and curiosity encounter the daunting, implacable forces of nature.

Peter Sloterdijk turns his keen eye to the history of western thought, conducting colorful readings of the lives and ideas of the world's most influential intellectuals. Featuring nineteen vignettes rich in personal characterizations and theoretical analysis, Sloterdijk's companionable volume casts the development of philosophical thinking not as a buildup of compelling books and arguments but as a lifelong, intimate struggle with intellectual and spiritual movements, filled with as many pitfalls and derailments as transcendent breakthroughs. Sloterdijk delves into the work (...) and times of Aristotle, Augustine, Bruno, Descartes, Foucault, Fichte, Hegel, Husserl, Kant, Kierkegaard, Leibniz, Marx, Nietzsche, Pascal, Plato, Sartre, Schelling, Schopenhauer, and Wittgenstein. He provocatively juxtaposes Plato against shamanism and Marx against Gnosticism, revealing both the vital external influences shaping these intellectuals' thought and the excitement and wonder generated by the application of their thinking in the real world. The philosophical "temperament" as conceived by Sloterdijk represents the uniquely creative encounter between the mind and a diverse array of cultures. It marks these philosophers' singular achievements and the special dynamic at play in philosophy as a whole. Creston Davis's introduction details Sloterdijk's own temperament, surveying the celebrated thinker's intellectual context, rhetorical style, and philosophical persona. (shrink)

This article discusses the very limited definability of philosophically interesting concepts as well as the prospects for the project of conceptual analysis.

Can one come to know what one wants? In some very simple cases, the answer has to be positive but in some other cases the answer is not so clear. The answer depends on what kind of self-knowledge one is taking about. This article also aims at elucidating the notion of knowledge of one's own desires.

Leibniz' Prinzip des zureichenden Grundes soll hier aufgrund von Russells Begriff des ‛logischen Eigennamens’ untersucht werden. Aus dieser Sicht kann vor der Schöpfung Gottes Begriff von Individuen keine individuelle Diesheit haben, sondern nur eine vollständige Beschreibung der noch nicht existierenden Individuen. Daraus ergibt sich, daß ein und dasselbe Individuum nicht durch mehr als eine Weltbeschreibung identifiziert werden kann, und darin darf man folglich Leibniz' tatsächlichen Beweis für die These des ‛Superessentialismus’ sehen, demzufolge alle Individuen ihre gesamten Eigenschaften mit Ausnahme der (...) Existenz wesenhaft besitzen. Im weiteren wird der Begriff einer Art möglicher Welten, die wir ‛parasitisch’ nennen wollen, erforscht. Dieser Begriff wird Leibniz' theoretischen Voraussetzungen gerecht, ohne zu seinen wenig überzeugenden Schlüssen zu führen. (shrink)

George Orwell argued that one of the four great motives for a prose writer was the desire â ~to push the world in a certain direction, to alter other peopleâ (TM)s idea of the kind of society that they should strive afterâ (TM). This book contains exciting new work by established and emerging scholars that explores political literature over the last century and a half. It shows how, from The Communist Manifesto to the dystopian future of Margaret Atwoodâ (TM)s Oryx (...) and Crake, writers have attempted to alter peopleâ (TM)s ideas, not always successfully. Eighteen chapters deal with a global array of writers and topics, from 1890s Australian bohemians and the anti-Peronism of Argentinaâ (TM)s Julio Cortàzar to Aris Alexandrouâ (TM)s Greek utopia and the harsh modern Zimbabwe of Yvonne Veraâ (TM)s The Stone Virgins. Other contributors critically examine the sexual politics of nineteenth century aestheticism, Theodor Adorno and Cultural Studies, Paul Auster and the altermodern, Yeatsâ (TM)s poetry, Celan and the Holocaust, the postmodernism of former-Yugoslaviaâ (TM)s Dubravka UgreÅ¡iÄ+, or the socialism of Australian Jean Devanny. Whether through informed studies of poetry and politics in Heidegger, Richard Marshâ (TM)s gothic novel The Beetle, how Thomas Pynchon and Don DeLillo deal with 9/11, the cultural politics of child abuse in Christos Tsiolkasâ (TM)s The Slap, or how the German politician Joschka Fischer lost weight, readers will be stimulated by a collection that shows political literatureâ (TM)s continuing ability to inform, enrage and engage readers from around the world.

"A learned work of rhetoric... compiled and made in the English tongue, of [one] who in judgment is profound, in wisdom and eloquence most famous." Thus in 1563 rhetorician Richard Rainolde praised _The Art of Rhetoric_, the work that brought into English the procedures of Ciceronian rhetoric-invention, disposition, style, memory, and delivery—the core of the academic curriculum in Renaissance England. Written in vigorous, native English, the _Art_ went through eight editions between 1553 and 1585. At least part of its appeal (...) was practicality. On the final page of his copy on Quintilian, Gabriel Harvey noted that _The Art of Rhetoric _is the "Daily bread of our common pleaders and discoursers." But its appeal was also academic. In 1619, nearly forty years after the _Art_ had lapsed from print, John Milton's teacher Alexander Gill invoked Wilson as he ridiculed the affectations of pretentiously learned language. Seen in its historical context, Wilson's _The Art of Rhetoric _reveals a great deal about the formal education of such authors as Shakespeare, Spenser, Jonson, and Milton. Since it bears directly on what is basic to imaginative literature—the art of language—the _Art_ encapsulates a literary context relevant to all those studying the English Renaissance, whether their approach is historicist, structuralist, deconstructionist, or new historicist. In addition, it will be of interest to students of rhetoric, education, and intellectual history in general. There have been four editions of the _Art_ in the twentieth century: two facsimiles and two original-spelling texts, none of which is in print. Peter Medine's edition modernizes the spelling and punctuation of the text of the second edition, which Wilson revised and expanded in 1560, and furnishes a fully critical apparatus, including introduction, textual notes, commentary, and glossary. As such, this edition makes available a central work of the English Renaissance in an accessible format. (shrink)

Words denoting “mother” in baby talk and in languages usually include nasal sounds, supporting Falk's suggestion that infant nasalized demand vocalizations might have motivated a first word. The linguistic contrast between maternal terms and paternal terms, which favor oral consonants, and the simple phonetic patterns of parental terms in both baby talk and languages also suggest parental terms could have been first words.
