This thesis is concerned with two interrelated sets of problems: How can we have knowledge in a universe of processes? How can knowledge be improved, and how is scientific progress possible? ;To address the epistemological question in conjunction with the ontological is not a common approach in contemporary philosophy of science. I therefore begin the dissertation by arguing that these two areas of philosophy are intimately interrelated, and that the one-sided concentration on epistemological issues has led to an unsatisfactory account (...) of the nature of knowledge. In particular it has led to a conflation of epistemology with methodology. I argue that methodologies carry with themselves certain presuppositions concerning the nature of the world and of human beings. ;I suggest that we should attempt to construct a philosophical system within which epistemology and ontology mutually support one another. Insights derived from modern science provide us with a basis for the construction of such a system. ;I begin this task by arguing that scientific knowledge can be viewed as an extension of perception. Relying on insights derived from Gregory and Piaget I emphasize the constructive characteristics of our perceptual system and argue that they find their counterpart in the constructive nature of modern science. ;Having outlined a constructivist view of knowledge I turn to the discussion of the ontological issues. ;I propose as an alternative the adoption of a metaphysics of processes. I outline such an ontology, basing my model upon ideas derived from Prigogine's research on dissipative structures and Pattee's investigation of hierarchical organization. I explain how dissipative structures create stability in an instable world and link this insight to the constructive features of our perceptual and conceptual systems. ;The resulting model shows how knowledge is possible in the strange world of processes which we probably inhabit. It further shows how knowledge can be improved and what progress through evolution means. This issue is pursued in greater detail in the last part of the dissertation. There I expound Waddington's cybernetic model of evolutionary change and show how it finds its counterpart in cognitive evolution. (shrink)

Despite decades of study, mimicry continues to inspire and challenge evolutionary biologists. This essay aims to assess recent conceptual frameworks for the study of mimicry and to examine the links between mimicry and related phenomena. Mimicry is defined here as similarity in appearance and/or behavior between a mimic and a model that provides a selective advantage to the mimic because it affects the behavior of a receiver causing it to misidentify the mimic, and that evolved (or is maintained by selection) (...) because of those effects. Mimics copy cues or signals that are already in use as part of a stable communication system, but offer misleading information to receivers. Mimicry overlaps, both conceptually and evolutionarily, with camouflage and perceptual exploitation but the overlap is only partial, which may create some confusion. Certain types of camouflage (e.g. masquerade) conform to the definition of mimicry, while others (e.g. background matching) are not considered mimicry because they prevent detection rather than recognition of the camouflaged animal. Mimicry, on the other hand, works by exploiting peculiarities of the receiver at higher stages of sensory processing involving recognition and classification of stimuli. Perceptual exploitation models of trait evolution are also closely related to mimicry, and sensory traps in particular may act as a precursor for true mimicry to evolve. The common thread through these diverse phenomena is deception of a receiver by a mimic. Thus receiver deception (i.e. perceptual error) emerges as a key characteristic of mimicry shared with some types of camouflage and perceptual exploitation. (shrink)

This book develops a theory of how the imagination functions, and how it evolved. The imagination is characterized as an embodied cognitive system. The system draws upon sensory-motor, visual, and linguistic capacities, but it is a flexible, developmental ability, typified by creative improvisation. The imagination is a voluntary simulation system that draws on perceptual, emotional, and conceptual elements, for the purpose of creating works that adaptively investigate external (environmental) and internal (psychological) resources. Beyond the adaptive useful values of this (...) system, imagination also possesses significant intrinsic value (e.g., in the joy of play, and states of wonder). The book argues that imagination is not a late arrival in the evolution of mind, but one of the earliest human abilities. (shrink)

How veridical is perception? Rather than representing objects as they actually exist in the world, might perception instead represent objects only in terms of the utility they offer to an observer? Previous work employed evolutionary modeling to show that under certain assumptions, natural selection favors such “strict‐interface” perceptual systems. This view has fueled considerable debate, but we think that discussions so far have failed to consider the implications of two critical aspects of perception. First, while existing models have (...) explored single utility functions, perception will often serve multiple largely independent goals. (Sometimes when looking at a stick you want to know how appropriate it would be as kindling for a campfire, and other times you want to know how appropriate it would be as a weapon for self‐defense.) Second, perception often operates in an inflexible, automatic manner—proving “impenetrable” to shifting higher‐level goals. (When your goal shifts from “burning” to “fighting,” your visual experience does not dramatically transform.) These two points have important implications for the veridicality of perception. In particular, as the need for flexible goals increases, inflexible perceptual systems must become more veridical. We support this position by providing evidence from evolutionary simulations that as the number of independent utility functions increases, the distinction between “interface” and “veridical” perceptual systems dissolves. Although natural selection evaluates perceptual systems only on their fitness, the most fit perceptual systems may nevertheless represent the world as it is. (shrink)

The sound system of a language must be able to support a perceptual contrast between different words in order to signal communicatively relevant meaning distinctions. In this paper, we use a simple agent-based exemplar model in which the evolution of sound-category systems is understood as a co-evolutionary process, where the range of variation within sound categories is constrained by functional pressure to keep different words perceptually distinct. We show that this model can reproduce several observed effects on (...) the range of sound variation. We argue that phonological systems can be seen as finding a relative optimum of variation: Efficient communication is sustained while at the same time, hidden category variation provides pathways for future evolution.

There is now a huge amount of interest in consciousness among scientists as well as philosophers, yet there is so much confusion and ambiguity in the claims and counter-claims that it is hard to tell whether any progress is being made. This ``position paper'' suggests that we can make progress by temporarily putting to one side questions about what consciousness is or which animals or machines have it or how it evolved. Instead we should focus on questions about the sorts (...) of architectures that are possible for behaving systems and ask what sorts of capabilities, states and processes, might be supported by different sorts of architectures. We can then ask which organisms and machines have which sorts of architectures. This combines the standpoint of philosopher, biologist and engineer. If we can find a general theory of the variety of possible architectures (a characterisation of ``design space'') and the variety of environments, tasks and roles to which such architectures are well suited (a characterisation of ``niche space'') we may be able to use such a theory as a basis for formulating new more precisely defined concepts with which to articulate less ambiguous questions about the space of possible minds. For instance our initially ill-defined concept (``consciousness'') might split into a collection of more precisely defined concepts which can be used to ask unambiguous questions with definite answers. As a first step this paper explores a collection of conjectures regarding architectures and their evolution. In particular we explore architectures involving a combination of coexisting architectural levels including: (a) reactive mechanisms which evolved very early, (b) deliberative mechanisms which evolved later in response to pressures on information processing resources and (c) meta-management mechanisms that can explicitly inspect evaluate and modify some of the contents of various internal information structures. It is conjectured that in response to the needs of these layers, perceptual and action subsystems also developed layers, and also that an ``alarm'' system which initially existed only within the reactive layer may have become increasingly sophisticated and extensive as its inputs and outputs were linked to the newer layers. Processes involving the meta-management layer in the architecture could explain the origin of the notion of ``qualia''. Processes involving the ``alarm'' mechanism and mechanisms concerned with resource limits in the second and third layers gives us an explanation of three main forms of emotion, helping to account for some of the ambiguities which have bedevilled the study of emotion. Further theoretical and practical benefits may come from further work based on this design-based approach to consciousness. A deeper longer term implication is the possibility of a new science investigating laws governing possible trajectories in design space and niche space, as these form parts of high order feedback loops in the biosphere.

Prior to the twentieth century, theories of knowledge were inherently perceptual. Since then, developments in logic, statis- tics, and programming languages have inspired amodal theories that rest on principles fundamentally different from those underlying perception. In addition, perceptual approaches have become widely viewed as untenable because they are assumed to implement record- ing systems, not conceptual systems. A perceptual theory of knowledge is developed here in the context of current cognitive science and neuroscience. During (...) class='Hi'>perceptual experience, association areas in the brain capture bottom-up patterns of activation in sensory-motor areas. Later, in a top-down manner, association areas partially reactivate sensory-motor areas to implement perceptual symbols. The stor- age and reactivation of perceptual symbols operates at the level of perceptual components – not at the level of holistic perceptual expe- riences. Through the use of selective attention, schematic representations of perceptual components are extracted from experience and stored in memory (e.g., individual memories of green, purr, hot). As memories of the same component become organized around a com- mon frame, they implement a simulator that produces limitless simulations of the component (e.g., simulations of purr). Not only do such simulators develop for aspects of sensory experience, they also develop for aspects of proprioception (e.g., lift, run) and introspec- tion (e.g., compare, memory, happy, hungry). Once established, these simulators implement a basic conceptual system that represents types, supports categorization, and produces categorical inferences. These simulators further support productivity, propositions, and ab- stract concepts, thereby implementing a fully functional conceptual system. Productivity results from integrating simulators combinato- rially and recursively to produce complex simulations. Propositions result from binding simulators to perceived individuals to represent type-token relations. Abstract concepts are grounded in complex simulations of combined physical and introspective events. Thus, a per- ceptual theory of knowledge can implement a fully functional conceptual system while avoiding problems associated with amodal sym- bol systems. Implications for cognition, neuroscience, evolution, development, and artificial intelligence are explored. (shrink)

Does natural selection favor veridical percepts—those that accurately depict objective reality? Perceptual and cognitive scientists standardly claim that it does. Here we formalize this claim using the tools of evolutionary game theory and Bayesian decision theory. We state and prove the “Fitness-Beats-Truth Theorem” which shows that the claim is false: If one starts with the assumption that perception involves inference to states of the objective world, then the FBT Theorem shows that a strategy that simply seeks to maximize expected-fitness (...) payoff, with no attempt to estimate the “true” world state, does consistently better. More precisely, the FBT Theorem provides a quantitative measure of the extent to which the fitness-only strategy dominates the truth strategy, and of how this dominance increases with the size of the perceptual space. The FBT Theorem supports the Interface Theory of Perception, which proposes that our perceptual systems have evolved to provide a species-specific interface to guide adaptive behavior, and not to provide a veridical representation of objective reality.

How did the human brain evolve so that consciousness of art could develop? In The Psychology of Art and the Evolution of the Conscious Brain, Robert Solso describes how a consciousness that evolved for other purposes perceives and creates art.Drawing on his earlier book Cognition and the Visual Arts and ten years of new findings in cognitive research, Solso shows that consciousness developed gradually, with distinct components that evolved over time. One of these components is an adaptive consciousness that (...) includes the ability to imagine objects that are not present--an ability that allows us to create visual art.Solso describes the neurological, perceptual, and cognitive sequence that occurs when we view art, and the often inexpressible effect that a work of art has on us. He shows that there are two aspects to viewing art: nativistic perception--the synchronicity of eye and brain that transforms electromagnetic energy into neuro-chemical codes--which is "hard-wired" into the sensory-cognitive system; and directed perception, which incorporates personal history and knowledge--the entire set of our expectations and past experiences. Both forms of perception are part of the appreciation of art, and both are products of the evolution of the conscious brain over hundreds of thousands of years.Solso also investigates the related issues of neurological and artistic perception of the human face, the effects of visual illusions, and the use of perspective. The many works of art used as examples are drawn from a wide range of artistic traditions, from ancient Egypt to Africa and India and the European Renaissance. (shrink)

To coordinate action, information must be transmitted, processed, and utilized to make decisions. Transmission of information requires the existence of a signaling system in which the signals that are exchanged are coordinated with the appropriate content. Signaling systems in nature range from quorum signaling in bacteria [Schauder and Bassler, Kaiser ], through the dance of the bees [Dyer and Seeley ], birdcalls [Hailman, Ficken, and Ficken, Gyger, Marler and Pickert, Evans, Evans, and Marler, Charrier and Sturdy ], and alarm (...) calls in many species [Seyfarth and Cheney, Green and Maegner,Manser, Seyfarth and Cheney ], up to human language. Information processing includes filtering – that is discarding irrelevant information and passing along what is important – and integration of multiple pieces of information. Integration includes logical inference and voting. Finally, the information must be used to make decisions with consequences for payoffs that drive evolution or learning. (shrink)

In this commentary, the idea of reciprocity potential indicators is tied in with ultimate accounts on sex differences in social sensitivity. It is proposed that, rather than crying, smiling is a more likely cooperative signal. The possibility of coevolution and polymorphism in perceptual and signalling systems are also discussed briefly, with a reference to Theory of Mind and Machiavellianism.

This essay explicates a structural theory of the historical evolution of world-systems. Rather than using societies as the unit of analysis the authors use intersocietal interaction networks (world-systems). This enables them to take theoretical account of the systemic development processes that are regional and inter-regional in scope and to formulate a more powerful theory that explains how thousands of egalitarian small-scale world-systems evolved, expanded and merged to become the hierarchical and global world-system of today.

This article presents the genesis of Evolutionary Systems Design (ESD) as a praxis that draws on General Evolution Theory and Social Systems Design methodology, in addition to Critical Systems Theory, to engage in lifelong learning and human development in partnership with the Earth. The contributions of Bela H. Banathy to the creation of ESD are portrayed as bridging evolutionary consciousness and evolutionary action. Following a brief description of the inspiration and mentorship provided by Bela in this (...) regard, the roots of ESD are traced back to General Evolution Theory. It is described how notions of evolutionary stewardship grew out of encounters with Bela and his work at the International Systems Institute, and were given operational viability through the methodology of Social Systems Design he developed. The fundamental tenets of ESD are presented and discussed by way of a four-stage evolutionary learning framework. Finally, the vehicle of Evolutionary Learning Community through which ESD operates is shown to embody the potential for individuals and groups to think, live, and act in harmony with the dynamics of which they are a part as a means to guide the conscious creation of sustainability.

Philosophers spend a lot of time worrying about rules. We worry about how one ought to live, about the rules of justification for beliefs and actions, about what it would be like if the rules of reason were rigorously followed, about what the rules are for scientific enquiry, about which rules govern the meaning of signs and the intentions of agents, and so on. Sometimes, we argue that there are no such rules as most of us want to believe there (...) are, rules which apply to all of us collectively and to each of us individually, which are beyond our ability to change, and whose violation is in some simple sense wrong. To this we often respond that without such rules we are all made somehow less, that our normative deliberations are a sham, or even that the whole business of living becomes somehow pointless.

The neuropsychology of religious activity in normal and selected clinical populations is reviewed. Religious activity includes beliefs, experiences, and practice. Neuropsychological and functional imaging findings, many of which have derived from studies of experienced meditators, point to a ventral cortical axis for religious behavior, involving primarily the ventromedial temporal and frontal regions. Neuropharmacological studies generally point to dopaminergic activation as the leading neurochemical feature associated with religious activity. The ventral dopaminergic pathways involved in religious behavior most closely align with the (...) action-extrapersonal system in the model of 3-D perceptual–motor interactions proposed by Previc . These pathways are biased toward distant space and also mediate related extrapersonally dominated brain functions such as dreaming and hallucinations. Hyperreligiosity is a major feature of mania, obsessive-compulsive disorder, schizophrenia, temporal-lobe epilepsy and related disorders, in which the ventromedial dopaminergic systems are highly activated and exaggerated attentional or goal-directed behavior toward extrapersonal space occurs. The evolution of religion is linked to an expansion of dopaminergic systems in humans, brought about by changes in diet and other physiological influences. (shrink)

This article outlines the evolution of a national research funding system over a timespan of more than 40 years and analyzes the development from a rather stable Humboldt-inspired floor funding model to a complex multi-tiered system where new mechanisms continually have been added on top of the system. Based on recent contributions to Historical Institutionalism it is shown how layering and displacement processes gradually have changed the funding system along a number of dimensions and thus how a series of (...) minor adjustments over time has led to a transformation of the system as a whole. The analysis also highlights the remarkable resistance of the traditional academically oriented research council system towards restructuring. Due to this resistance the political system has, however, circumvented the research council system and implemented change through other channels of the funding system. For periods of time these strategies have marginalized the role of the councils. (shrink)

The chapter outlines an abstract theoretical framework that is currently (re-)emerging in the course of a theoretical convergence of several disciplines. In the first section, the fundamental problem of perception theory is formulated, namely, the generation, by the perceptual system, of meaningful categories from physicogeometric energy patterns. In the second section, it deals with basic intuitions and assumptions underlying what can be regarded as the current Standard Model of Perceptual Psychology and points out why this model is profoundly (...) inadequate for dealing with the fundamental problem of perception theory. In the third section, it discusses a level of analysis that promises to be fruitful for dealing, in conformity with established procedures of the natural sciences, with the problem of perceptual “meaning” and the problem of what constitutes a “perceptual object.” In the fourth section, it outlines a theoretical perspective on basic principles of the perceptual system which centers on the notions of complex data types and conceptual forms, and draws an entirely different theoretical picture of the role of the sensory input than traditional accounts. The final section focusses on the issue of material qualities and discusses, within the general theoretical framework outlined, some observations and results on the perception of certain material properties, namely, lustrous and glassy appearances.

The paper explores the basis for decision?making and policy with regard to the Environment. Clearly these should be based on knowledge of possible consequences and accompanying risk assessments involving the linked behaviour of the many interacting human actors within a socio?economic system and the ecological, and physical systems in which they are embedded. The paper describes the Complex Systems approach to these problems, showing the kind of models that are required in order to obtain whatever limited knowledge is (...) possible about the co?evolution of the human and environmental systems involved. Several practical examples are described and the models briefly presented. These are shown as examples of what should be required for the creation of the necessary basis for making policy and decision explorations with an integrated view of the system as a whole, instead of separate parts studied in detail by experts of specific disciplines. This provides a framework for making real use of the ?knowledge? of disciplinary experts, and linking their narrow views to the overall, practical consequences in the real world of possible policy options.

Today a change is imperative in approaching global problems: what is needed is not arm-twisting and power politics, but searching for ways of co-evolution in the complex social and geopolitical systems of the world. The modern theory of self-organization of complex systems provides us with an understanding of the possible forms of coexistence of heterogeneous social and geopolitical structures at different stages of development regarding the different paths of their sustainable co-evolutionary development. The theory argues that the (...) evolutionary channel to the observed increasing complexity is extremely narrow and only certain discrete spectra of relatively stable self-maintained structures are feasible in complex systems. There exists a restricted set of ways of assembling a complex evolutionary whole from diverse parts. The law of nonlinear synthesis of complex structures reads: the integration of structures in more complex ones occurs due to the establishment of a common tempo of their evolution. On the basis of the theory, we can see not only desirable but also attainable futures. (shrink)

Abstract.Growing interest in the origin of life, the physical foundations of biological theory, and the evolution of animal social systems has led to increasing efforts to understand the processes by which elements or living systems at one level of organizational complexity combine to form stable systems of higher order. J. Bronowski saw the need to extend or reformulate evolutionary theory to deal with the hierarchy problem and to account for the evolution of systems of (...) “stratified stability.” The hierarchy problem has become a matter of great interest also in nonequilibrium thermodynamic theory.An effort is made here to develop an abstract, phenomenological model, based on the laws of thermodynamics, to account for the origin and hierarchical evolution of living systems. It is argued that the principle of minimum entropy production, developed by I. Prigogine, applies generally to all thermodynamic systems and processes and is implicit in an extended and more complete formulation of the second law of thermodynamics. From this are derived a thermodynamic criterion and a principle of thermodynamic selection governing the formation of stable systems of “elements” of various levels of organization. Thermodynamic selection gives rise to the creation of “elements” having increasingly “open” characteristic structures which may combine spontaneously to form “social” or crystalline systems capable of growing and reproducing themselves through processes of fissioning or budding. Such simple, self‐reproducing systems are capable of evolving by natural selection, which is seen to be a special case of the more general process of thermodynamic selection. The principle of natural selection, thus formulated, has the character of a fundamental physical law. Self‐reproducing systems with suitably open hereditary programs may combine to form stable social systems, which may grow and reproduce as a unit. In this way self‐reproducing systems of increasing hierarchical order, size, and organizational complexity may evolve through processes of thermodynamic (natural) selection. Some implications of this open‐ended model and opportunities for testing its empirical and theoretical utility are explored. (shrink)

Every living entity requires the capacity to defend against viruses in some form. From bacteria to plants to arthropods, cells retain the capacity to capture genetic material, process it in a variety of ways, and subsequently use it to generate pathogen-specific small RNAs. These small RNAs can then be used to provide specificity to an otherwise non-specific nuclease, generating a potent antiviral system. While small RNA-based defenses in chordates are less utilized, the protein-based antiviral invention in this phylum appears to (...) have derived from components of the same ancestral small RNA machinery. Based on recent evidence, it would seem that RNase III nucleases have been reiteratively repurposed over billions of years to provide cells with the capacity to recognize and destroy unwanted genetic material. Here we describe an overview of what is known on this subject and provide a model for how these defenses may have evolved. RNase III nuclease domains are widely used in an array of RNA metabolic functions as well as antiviral defenses. Here, we review their current usage as well as provide insight into how these domains may have shaped all major antiviral pathways over the course of evolution. (shrink)

The dynamics of populations of self-replicating, hierarchically structured individuals, exposedto accidents which destroy their sub-units, is analyzed mathematically, specifically with regardto the roles of redundancy and sexual repair. The following points emerge from this analysis:0 A population of individuals with redundant sub-structure has no intrinsic steady-statepoint; it tends to either zero or infinity depending on a critical accident rate α c . Increased redundancy renders populations less accident prone initially, but populationdecline is steeper if a is greater than a fixed (...) value α d . Periodic, sexual repair at system-specific intervals prevents continuous decline and stabilizesthe population insofar as it will now oscillate between two fixed population levels. The stabilizing sexual interval increases with increased complexity provided this is accom-panied by appropriate levels of redundancy. The model closely simulates the dynamics of heterosis effects. Repair fitness is a population fitness: the chance of an individual being repaired is a functionof the statistical make-up of the population as a whole at that particular period. Populationsliving at α > α c either engage in sexual repair at the appropriate time or they die out. The mathematical properties of the model illustrate mechanisms which possibly played arole in the evolution of a mortal soma in relation to sexual reproduction. (shrink)

The evolution of the technology standard alliance is examined using complex adaptive system theory. Taking TSA as a dynamic CAS, an echo model is constructed to depict the mechanism of its evolution, and a model is simulated on the NetLogo platform. The echo model includes a basic model, an extended model, and a three-layer echo model. The adhesive aggregation of agents is explained, and the three evolutionary stages of agents’ entry, migration, and exit are analyzed. Moreover, the adaptability (...) of agents in TSA is quantified. The results of simulation show the evolution of the TSA in relation to the two aspects of agent adhesion aggregation and agent resource interaction, and they demonstrate the dynamic and complex hierarchical structure of the TSA system. It is proposed that greater matching ability, moderate behavior income, and lower behavior cost are more conducive to the evolution and development of TSA. Additionally, the echo model is reconstructed to expand the range of application of CAS theory. (shrink)

What social scientists study is the evolution of historical systems. Evolution refers to the trajectory of processes inherent in the structure of the system. The structure of a system cannot explain either its genesis nor what happens to it following its inevitable structural crisis. The mechanisms of the evolution of the modern worldsystem, a system structured around the primum mobile of the endless accumulation of capital, is described.

As a rule, Hayek has not been treated kindly by scholars. One would expect that a political theorist and economist of his stature would be charitably, if not sympathetically, read by commentators; instead, Hayek often elicits harsh dismissals. This is especially true of his fundamental ideas about the evolution of society and reason. A reader will find influential discussions in which his analysis is described as “dogmatic,” “unsophisticated,” and “crude.” In this chapter I propose to take a fresh start, (...) sketching a sympathetic interpretation of Hayek’s accounts of social evolution and mind as fundamental to his thinking. My basic claim is that Hayek’s views on social evolution and reason are not only intimately bound together, but they also depend on his analyses of complex orders, scientific explanations of such orders, and the place of rules in complex orders. Because so few commentators recognize that his claims about evolution are embedded in a system of ideas,1 most misunderstand him. (shrink)

Owing to intensive development of the theory of self-organization of complex systems called also synergetics, profound changes in our notions of time occur. Whereas at the beginning of the 20th century, natural sciences, by picking up the general spirit of Einstein's theory of relativity, consider a geometrization as an ideal, i.e. try to represent time and force interactions through space and the changes of its properties, nowadays, at the beginning of the 21st century, time turns to be in the (...) focus of attention. It turns to be possible to represent space through time, because synergetics shows that historical and evolutionary stages of development of a complex structure can be found now, in its present spatial configuration. A whole series of paradoxical notions, such as "the influence of the future upon the present", a "possibility of touching of a rather remote future today", "availability of the past and the future now, in praesenti", "irreversibility and elements of reversibility in the course of evolutionary processes in time", "discrete unites, quanta of time", appear in synergetics.

This book presents an original comprehensive approach to some of the most difficult problems concerning sense-perception and other mental states. After rejecting prevailing approaches, the author presents his own viewpoint which may be characterized as direct, critical realism. Basing his conclusions on conceptual analysis, psychological evidence and historical considerations, the author is able to offer new insights into traditionally unsolved problems concerning the nature of perceptual states, the ontological status of perceptual environment, the cognitive mechanism in perception and (...) the explanation of perceptual mistakes. The book also discusses the implications of this approach for other mental states such as memory and consciousness. (shrink)

The development of educational technologies is enhancing a distinctive feature of learning environments: the learner’s personalized environment. However, the current literature in e-learning seems to neglect an important discussion: will individuals and organizations face an enhancement concerning ethical dilemmas due to this evolution? To promote this discussion, this paper builds on a consideration of e-learning definition and its ethical dilemmas, and human-centred learning concept and its dimensions, to examine the implications of integrating social and cultural contexts. By examining the (...) evolution of e-learning management systems the argument progresses to a discussion of the relationships between pedagogy and ethics. By framing evidence at different scales, the authors critically reflect on the ethical dilemmas embedded in e-learning systems. The discussion concludes with advocating the adoption of an extension of “three P” mode of pedagogy to become the “P3E” model: personalization, participation, productivity, lecturer’s ethics, learner’s ethics, and organizational ethics.

The concept of “gradually adaptive frameworks” is introduced as a model with the potential to describe the evolution of belief evaluative systems through the consideration of reasonable arguments and evidence. This concept is demonstrated through an analysis of specific points of disagreement between David Elliott’s praxial philosophy and Bennett Reimer’s aesthetic philosophy. A parallel case of disagreement is introduced from the literature of contemporary epistemology. This case, comprised of a disagreement between Thomas Kelly and Richard Feldman, deals explicitly (...) with the subject of “peer disagreement”. The discussion of this conceptual analysis is used to establish an advocacy position for the central positioning of critical thinking skills in any educative endeavor. (shrink)

The mammary gland is a skin gland unique to the class Mammalia. Despite a growing molecular and histological understanding of the development and physiology of the mammary gland, its functional and morphological origins have remained speculative. Numerous theories on the origin of the mammary gland and lactation exist. The purpose of the mammary gland is to provide the newborn with copious amounts of milk, a unique body fluid that has a dual role of nutrition and immunological protection. Interestingly, antimicrobial enzymes, (...) such as xanthine oxidoreductase or lysozyme, are directly involved in the evolution of the nutritional aspect of milk. We outline that xanthine oxidoreductase evolved a dual role in the mammary gland and hence provide new evidence supporting the hypothesis that the nutritional function of the milk evolved subsequent to its protective function. Therefore, we postulate that the mammary gland evolved from the innate immune system. In addition, we suggest that lactation partly evolved as an inflammatory response to tissue damage and infection, and discuss the observation that the two signaling pathways, NF‐kB and Jak/Stat, play central roles in inflammation as well as in lactation.

This article draws on analysis of a variety of problems emerging from practical applications of Group Decision Support Systems (GDSS) to propose a fundamental evolution of decision support models from the traditional single decision-spine model to the decision-hedgehog. It positions decision making through the construction of narratives making the rhizome that constitutes the body of the hedgehog with the fundamental aim of enriching understanding of the contexts of decision making.

Arbib offers a comprehensive, elegant formulation of brain/language evolution; with significant implications for social as well as biological sciences. Important psychological antecedents and later correlates are presupposed; their conceptual enrichment through protosign and protospeech is abbreviated in favor of practical communication. What culture and whether protosign and protospeech involve a protoculture are not considered. Arbib also avoids dealing with the question of evolution of mind, consciousness, and self.
