Humans are strongly lateralized for manual gestures at both individual and population levels. In contrast, the laterality bias in primates is less strong, leading some to suggest that lateralization evolved after the Pan and Homo lineages diverged. However, laterality in humans is also context-dependent, suggesting that observed differences in lateralization between primates and humans may be related to external factors such as the complexity of the social environment. Here we address this question in wild chimpanzees and examine the (...) extent to which the laterality of manual gestures is associated with social complexity. Right-handed gestures were more strongly associated with goal-directed communication such as repair through elaboration in response to communication failure than left-handed gestures. Right-handed gestures occurred in evolutionarily urgent contexts such as in interactions with central individuals in the network, including grooming reciprocity and mating, whereas left-handed gestures occurred in less-urgent contexts, such as travel and play. Right-handed gestures occurred in smaller parties and in the absence of social competition relative to left-handed gestures. Right-handed gestures increased the rate of activities indicating high physiological arousal in the recipient, whereas left-handed gestures reduced it. This shows that right- and left-handed gestures differ in cognitive and social complexity, with right-handed gestures facilitating more complex interactions in simpler social settings, whereas left-handed gestures facilitate more rewarding interactions in complex social settings. Differences in laterality between other primates and humans are likely to be driven by differences in the complexity of both the cognitive skills underpinning social interactions and the social environment.

Written for non-experts, this volume introduces the mechanisms that underlie reticulate evolution. Chapters are either accompanied with glossaries that explain new terminology or timelines that position pioneering scholars and their major discoveries in their historical contexts. The contributing authors outline the history and original context of discovery of symbiosis, symbiogenesis, lateral gene transfer, hybridization or divergence with gene flow, and infectious heredity. By applying key insights from the areas of molecular (phylo)genetics, microbiology, virology, ecology, systematics, immunology, epidemiology and computational science, (...) they demonstrate how reticulate evolution impacts successful survival, fitness and speciation. Reticulate evolution brings forth a challenge to the standard Neo-Darwinian framework, which defines life as the outcome of bifurcation and ramification patterns brought forth by the vertical mechanism of natural selection. Reticulate evolution puts forward a pattern in the tree of life that is characterized by horizontal mergings and lineage crossings induced by symbiosis, symbiogenesis, lateral gene transfer, hybridization or divergence with gene flow, and infective heredity, making the “tree of life” look more like a “web of life.” On an epistemological level, the various means by which hereditary material can be transferred horizontally challenges our classic notions of units and levels of evolution, fitness, modes of transmission, linearity, communities, and biological individuality. The case studies presented examine topics including the origin of the eukaryotic cell and its organelles through symbiogenesis; the origin of algae through primary and secondary symbiosis and dinoflagellates through tertiary symbiosis; the superorganism and holobiont as units of evolution; how endosymbiosis induces speciation in multicellular life forms; transferrable and non-transferrable plasmids and how they symbiotically interact with their host; the means by which pro- and eukaryotic organisms transfer genes laterally (bacterial transformation, transduction and conjugation as well as transposons and other mobile genetic elements); hybridization and divergence with gene flow in sexually-reproducing individuals; current (human) microbiome and viriome studies that impact our knowledge concerning the evolution of organismal health and acquired immunity; and how symbiosis and symbiogenesis can be modelled in computational evolution.

A detailed discussion of later Wittgenstein's take on the logicism of Frege and Russell. The focus is on Wittgenstein's views in his 1939 Lectures on the Foundations of Mathematics.

John Dewey's Experience and Nature has been considered the fullest expression of his mature philosophy since its eagerly awaited publication in 1925. Irwin Edman wrote at that time that "with monumental care, detail and completeness, Professor Dewey has in this volume revealed the metaphysical heart that beats its unvarying alert tempo through all his writings, whatever their explicit themes." In his introduction to this volume, Sidney Hook points out that "Dewey's Experience and Nature is both the most suggestive and most (...) difficult of his writings." The meticulously edited text published here as the first volume in the series The Later Works of John Dewey, 1925-1953 spans that entire period in Dewey's thought by including two important and previously unpublished documents from the book's history: Dewey's unfinished new introduction written between 1947 and 1949, edited by the late Joseph Ratner, and Dewey's unedited final draft of that introduction written the year before his death. In the intervening years Dewey realized the impossibility of making his use of the word 'experience' understood. He wrote in his 1951 draft for a new introduction: "Were I to write (or rewrite) Experience and Nature today I would entitle the book Culture and Nature and the treatment of specific subject-matters would be correspondingly modified. I would abandon the term 'experience' because of my growing realization that the historical obstacles which prevented understanding of my use of 'experience' are, for all practical purposes, insurmountable. I would substitute the term 'culture' because with its meanings as now firmly established it can fully and freely carry my philosophy of experience.". (shrink)

In his remarks from later period, Ludwig Wittgenstein is frequently concerned with so-called external roots of our logical operations. He asks questions like: ‘How is anything like logical necessity possible?‘; ‚How is possible anything like following a logical rule under normal circumstances?‘; ‚Where is the compelling force of a logical proof coming from?‘; etc. In the philosophical community, it is generally accepted that the later Wittgenstein’s remarks deal with these questions, but the philosophical motivation behind these remarks is still not (...) clear. Instead, there is a growing disagreement among various interpretations over these remarks. The present consideration is built upon the belief that Wittgenstein’s remarks try to communicate a new sense to us. I argue that, contrary to the generally accepted view, there is a new and positive sense in these remarks. My aim in this paper is to clarify the philosophical motivation behind them. (shrink)

This a general account of the school of Mo-tzu, its social basis as a movement of craftsmen, its isolated place in the Chinese tradition, and the nature of its later contributions to logic, ethics, and science. It assesses the relation of Mohist thinking to the structure of the Chinese language, and grapples with the textual dynamics of later Mohist writings, particularly in regard to grammar and style, technical terminology, the use and significance of stock examples, and overall organization. Includes edited (...) and annotated Chinese text with an English translation and commentary, a glossary, and a photographic reproduction of the unemended text from the Taoist Patrology. (shrink)

The writings of the later Mohists are generally taken to contain several updates to the consequentialist ethical view held by the Mohist school. In this paper, I defend one interpretation of those updates and how they may have served, within the Mohists’ argumentative context, to make their views more defensible. I argue that we should reject A.C. Graham’s prominent interpretation, on which the later Mohists’ argumentative strategy is to develop a conception of the a priori and to ground their ethical (...) view in a form of a priori rationalism. I contend, instead, that the strength of the later Mohists’ ethical view comes largely from their adoption of a subjective criterion for identifying what counts as a benefit within their consequentialist view. I show how the adoption of this subjective criterion fits within a larger trend in later Mohist thought of coming to terms with the diversity of people’s evaluative standpoints, and further show how it equips the later Mohists with worthwhile responses to their philosophical rivals.

In his Symposium Plato sought to provide for posterity a portrait of his beloved companion and teacher Socrates, focusing on two main features: Socrates as a mystagogue or spiritual guide and Socrates as a paragon of philosophical virtue. Plato’s depiction of these two aspects of the Socratic persona impressed so many writers and artists of later centuries that the Symposium became one of Plato’s best known and most admired dialogues. For many early Christian thinkers Socrates’ account of Erôs or ‘passionate (...) desire’ (imparted to him by the priestess Diotima) established that love is not merely a central aspect of human experience but also the means by which mortal beings achieve union with the divine. Following the lead of Marsilio Ficino, numerous Renaissance poets and artists praised a special ‘Socratic’ or ‘Platonic’ kind of love, inspired by the perception of physical beauty but fully realized in a life of virtuous conduct. -/- .

This volume provides an authoritative edition of Dewey’s _The Quest for Cer­tainty: A Study of the Relation Between Knowledge and Action. _The book is made up of the Gifford Lectures deliv­ered April–May 1929 at the University of Edinburgh. Writing to Sidney Hook, Dewey described this work as “a criti­cism of philosophy as attempting to at­tain theoretical certainty.” In the _Philo­sophical Review _Max C. Otto later elaborated: “Mr. Dewey wanted, so far as lay in his power, to crumble into dust, once (...) and for all, ‘the chief fortress of the classic philosophical tradition.”. (shrink)

The Mohists may have been the first consequentialists on earth. Their most important principles are that right action is what benefits the world and that the underlying outlook for benefiting the world is inclusive care, whereby each person receives equal consideration. The early Mohists are clearly objective-list consequentialists, whereby benefiting the world amounts to promoting the most basic goods. Stephens argues that the later Mohists shift to a preference-satisfaction consequentialism whereby benefiting the world amounts to promoting what happens to please (...) individual people. Stephens argues that while the direct texts are ambiguous between an objective-list interpretation and a preference-satisfaction interpretation, the latter better explains later Mohist engagement with opponents. I argue that the direct texts actually preclude Stephens’ preference-satisfaction interpretation, which moreover has the later Mohists concede an implausible amount to their opponents. (shrink)

This book shows that Ludwig Wittgenstein’s later philosophical methods can be fruitfully applied to several problems in contemporary moral philosophy. The author considers Wittgenstein’s ethical views and addresses such topics as meta-ethics, objectivity in ethics and moral perception. Readers will gain an insight into how Wittgenstein thought about philosophical problems and a new way of looking at moral questions. The book consists of three parts. In the first part, Wittgenstein’s later philosophical methods are discussed, including his comparison of philosophical methods (...) to therapies. The book then goes on to explore how these methods give insight into Wittgenstein’s ethical views. Readers will see how these are better understood when read in the light of his later philosophical thought. In the third part, Wittgenstein’s later methods are applied to problems in contemporary moral philosophy, including a look at questions for moral advice. The author reviews and criticizes some of the secondary literature on Wittgenstein’s later philosophical methods and indicates how the topic of the book can be developed in future research. There is something of value for readers of all levels in this insightful and well written volume. It will particularly appeal to scholars and students of Wittgenstein, of philosophy, and of ethics.

This volume presents critical writings on the work of the later mercantilists. Sir Josiah Child was elected a governor of the East India Company in 1681. His reputation as an economist rests on his book 'A New Discourse of Trade' published in 1693. His work stimulated a wide range of discussion of such topics as interest rates, population, wage policy, poor relief and colonization. Despite many liberal elements in his thinking, he was a typical Mercantilist in his preference for administrative (...) solutions to economic problems. John Locke, best known for his work on political philosophy, made a major contribution to the debate on the rate of interest in his essay 'Some Considerations of the Consequences of the Lowering of Interest and Raising the Value of Money' (1692). The central theme of that pamphlet was that the rate of interest, being the price for the hire of money, is determined by the demand for and supply of money, which Parliament is powerless to affect. Locke's other major contribution to economic thought was the so called labour theory of private property contained in the 'Two Treaties on Government' (1690), a classic in the history of political philosophy.

Many vertebrate animals approximate, to various degrees, the “split‐brain” condition that results from surgery done in humans to treat severe epilepsy, with very limited connection between the left and right sides of the upper parts of the brain. The split‐brain condition has been the topic of extensive philosophical discussion, because it appears, in some circumstances, to give rise to two minds within one body. Is the same true of these animals? This article attempts to make progress on two difficult topics—animal (...) experience, and the consequences of the human split‐brain condition—by considering both at once. (shrink)

We argue that lateralities are not merely a result of phylogenetic processes but reflect probability functions that are influenced by task characteristics and extended practice. We support our argument by empirical findings on lateral biases in early infancy in general, and footedness in particular, and on hand preferences in nonhuman primates.

The lateral mobility of membrane lipids and proteins is presumed to play an important functional role in biomembranes. Photobleaching studies have shown that many proteins in the plasma membrane have diffusion coefficients at least an order of magnitude lower than those obtained when the same proteins are reconstituted in artificial bilayer membranes. Depending on the protein, it has been shown that either the cytoplasmic domain or the ectodomain is the key determinant of its lateral mobility. Single particle tracking microscopy, which (...) allows the motions of single or small groups of membrane molecules to be followed, promises not only to reveal new features of membrane dynamics, but also to help explain longstanding puzzles presented by the photobleaching studies, particularly the so‐called immobile fraction. The combination of the two complementary technologies should measurably enhance our understanding of membrane microstructure. (shrink)

This paper portrays the later Wittgenstein’s conception of contradictions and his therapeutic approach to them. I will focus on and give relevance to the Lectures on the Foundations of Mathematics, plus the Remarks on the Foundations of Mathematics. First, I will explain why Wittgenstein’s attitude towards contradictions is rooted in: a rejection of the debate about realism and anti-realism in mathematics; and Wittgenstein’s endorsement of logical pluralism. Then, I will explain Wittgenstein’s therapeutic approach towards contradictions, and why it means that (...) a contradiction is not a problem for logic and mathematics. Rather, contradictions are problematic when we do not know what to infer from them. Once a meaning is established through a new rule of inference, the contradiction becomes a usable expression like many others in our inferential apparatus. Thus, the apparent problem is dissolved. Finally, I will take three examples of dissolved contradictions from Wittgenstein to clarify further his notion. I will conclude considering why his position on contradictions led him to clash with Alan Turing, and whether the latter was convinced by the Wittgensteinian proposal. (shrink)

This volume offers a critical examination of the later philosophical views of Vladimir Solov’ëv, arguably Russia’s most famous and most systematic philosopher. It offers a philosophically informed approach to this pivotal figure and to his era. Inside, readers will discover a detailed portrait of the often overlooked evolution of the philosopher’s views during the final two decades of his life. The author explores Solov’ëv’s still evolving aesthetic philosophy and his entry into the lively Russian discussion of free will. The work (...) then turns to the philosopher’s mature statements on many figures from within the history of philosophy. This includes Kant and Hegel. Next, readers will learn about his disagreements with several contemporaries as well as contemporaneous movements. These include positivism and materialism. In addition, the coverage includes an elucidation and examination of Solov’ëv’s final expression of his ethical philosophy as set forth in his major ethical treatise Justification of the Moral Good. The overall picture that emerges is of a much more vibrant and heated philosophical community than typically portrayed in Western secondary literature. The book ends with a reflection on the rise of Solov’ëv as a religious mystic at the expense of a critical evaluation of his thought. (shrink)

One of intuitions driving the acceptance of a neat structured tree of life is the assumption that organisms and the lineages they form have somewhat stable spatial and temporal boundaries. The phenomenon of symbiosis shows us that such ‘fixist’ assumptions does not correspond to how the natural world actually works. The implications of lateral gene transfer (LGT) have been discussed elsewhere; I wish to stress a related point. I will focus on lateral function transfer (LFT) and will argue, using examples (...) of what many would call ‘superorganisms’, that the emergence of symbiotic individuals revives the importance of functional and adaptationist thinking in how we conceptualize the lineages of biological individuals. The consequence of the argument is that, if we really want to hold onto tree of life thinking, we had better accept that new saplings appear and disappear all the time. (shrink)

The object of this essay is to discuss Ludwig Wittgenstein's remarks inPhilosophical Investigationsand elsewhere in the posthumously published writings concerning the role of therapy in relation to philosophy. Wittgenstein's reflections seem to suggest that there is a kind of philosophy or mode of investigation targeting the philosophical grammar of language uses that gratuitously give rise to philosophical problems, and produce in many thinkers philosophical anxieties for which the proper therapy is intended to offer relief. Two possible objectives of later Wittgensteinian (...) therapy are proposed, for subjectivepsychologicalversus objectivesemanticsymptoms of ailments that a therapy might address for the sake of relieving philosophical anxieties. The psychological in its most plausible form is rejected, leaving only the semantic. Semantic therapy in the sense defined and developed is more general and long-lasting, and more in the spirit of Wittgenstein's project on a variety of levels. A semantic approach treats language rather than the thinking, language-using subject as the patient needing therapy, and directs its attention to the treatment of problems in language and the conceptual framework a language game use expresses in its philosophical grammar, rather than to soothing unhappy or socially ill-adjusted individual psychologies.

This chapter provides a broadly sympathetic historical account of post-Kantian empiricist approaches to mathematics and logic. It focuses primarily but on John Stuart Mill’s radical empiricism and logical positivism, but also on Rudolf Carnap and Moritz Schlick. The later work of W. V. O. Quine is also treated.

Later Platonists and their Heirs among Christians, Jews and Muslims offers a thought-provoking exploration of the reception of Platonism among communities of faith from early Christianity to the sixteenth century, from the Byzantine East to the Latin West. Rare emphasis is placed on the importance of Platonic thought and its diffusion in late antique and medieval Syria, Armenia, and Georgia but also among Arab and Jewish intellectuals from the seventh century onwards. As such, the volume makes a statement against the (...) separation of Neoplatonic philosophy from Christianity and the other Abrahamic faiths, since all four traditions promoted a life of virtue and goodness despite operating under different divine auspices. The volume seeks to establish paths of transmission and modes of adaptation across times and places. (shrink)

Martin Heidegger was a central figure in 20th century Western philosophy. In evaluating his work from the perspective of the early 21st century it is clear that his influence crossed disciplinary lines. This work aims to address one area where Heidegger's thinking has had tremendous impact---theology. Specifically, Heidegger's later writings are selectively examined in order to determine the bearing they have on the issue of God. ;The route to God, in a strict confessional sense, is neither easy nor direct in (...) the Heideggerian corpus. As a result, the first methodological tack used throughout this study establishes Heidegger's abiding thematic interests. Only after appreciating the continuity and context of his work can tentative and cautious theological applications be made as the second methodological tack. This approach simultaneously upholds the integrity of Heidegger's thought and protects the theological discipline from speculative forays antithetical to its mission. The hope is that the later Heidegger will be seen as a productive and engaging dialogue partner for theology. His voice deepens theology's traditional discourse about God as well as challenges modes of expression that are exclusivistic and ineffectual in the postmodern era. ;The following structure exposes the outreach of the later Heideggerian oeuvre to theological thought regarding God. The first two chapters contextualize Heidegger. Chapter one situates Heidegger on the stage of Western philosophy with the distinction of having creatively raised the question of the meaning of Being to a new level of urgency. Chapter two identifies two formative influences from Heidegger's very early career---phenomenology and a course load involving religious topics. ;The third and fourth chapters make connections between the later texts and God. Chapter three introduces the importance of poetry and the dynamics of poetics. The venturesome poet inhabits the "between" and restores authentic human dwelling as measured against the Godhead. Chapter four further develops Holderlin's significance and introduces Nietzsche's importance for exposing the challenge of godlessness during the needy time: the gods have fled and God is dead. ;The Reprise recapitulates the salient themes presented and recommends promising areas for future research.
