The Interface Theory of Perception, as stated by D. Hoffman, says that perceptual experiences do not to approximate properties of an “objective” world; instead, they have evolved to provide a simplified, species-specific, user interface to the world. Conscious Realism states that the objective world consists of ‘conscious agents’ and their experiences. Under these two theses, consciousness creates all objects and properties of the physical world: the problem of explaining this process reverses the mind-body problem. In support of the interface theory (...) I propose that our perceptions have evolved, not to report the truth, but to guide adaptive behaviors. Using evolutionary game theory, I state a theorem asserting that perceptual strategies that see the truth will, under natural selection, be driven to extinction by perceptual strategies of equal complexity but tuned instead to fitness. I then give a minimal mathematical definition of the essential elements of a “conscious agent.” Under the conscious realism thesis, this leads to a non-dualistic, dynamical theory of conscious process in which both observer and observed have the same mathematical structure. The dynamics raises the possibility of emergence of combinations of conscious agents, in whose experiences those of the component agents are entangled. In support of conscious realism, I discuss two more theorems showing that a conscious agent can consistently see geometric and probabilistic structures of space that are not necessarily in the world per se but are properties of the conscious agent itself. The world simply has to be amenable to such a construction on the part of the agent; and different agents may construct different structures as seeming to belong to the world. This again supports the idea that any true structure of the world is likely quite different from what we see. I conclude by observing that these theorems suggest the need for a new theory which resolves the reverse mind-body problem, a good candidate for which is conscious agent theory. (shrink)

_Natural Language and Possible Minds: How Language Uncovers the Cognitive Landscape of Nature_ examines the intrinsic connection between natural language and the nature of mentality, offering to show how language can shed light on the forms of other types of mentality in non-humans.

This paper is an attempt at exploring the possibility of reconciling the two interpretations of biolinguistics which have been recently projected by Koster(Biolinguistics 3(1):61–92, 2009). The two interpretations—trivial and nontrivial—can be roughly construed as non-internalist and internalist conceptions of biolinguistics respectively. The internalist approach boils down to a conception of language where language as a mental grammar in the form of I-language grows and functions like a biological organ. On the other hand, under such a construal consistent with Koster’s (Biolinguistics (...) 3(1):61-92, 2009), the non-internalist version does not necessarily have to be externalist in nature; rather it is a matter of mutual reinforcement of biology and culture under the rubric of a co-evolutionary dynamics. Here it will be argued that the apparent dichotomy between these two conceptions of biolinguistics can perhaps be resolved if we have a richer synthesis that accounts for both internalism and non-internalism.

This paper approaches the question of how to describe the higher-level internal structures and representations of cognitive systems across various kinds of nonhuman (neuro)cognitive systems. While much research in cognitive (neuro)science and comparative cognition is dedicated to the exploration of the (neuro)cognitive mechanisms and processes with a focus on brain-behavior relations across different non-human species, not much has been done to connect (neuro)cognitive mechanisms and processes and the associated behaviors to plausible higher-level structures and representations of distinct kinds of cognitive (...) systems in non-humans. Although the study of (neuro)cognitive mechanisms and processes can certainly be revealing, (neuro)cognitive mechanisms and processes are underspecified with respect to internal structures and representations of non-human cognitive systems because multiple such mechanisms can target, or be mapped onto, the same internal structure or vice versa. This paper outlines a biosemiotic approach to this linking problem in order to bridge the gap between functions of (neuro)cognitive systems in different species and the higher-level cognitive structures and representations. It is contended that the higher-level internal structures and representations of various cognitive systems are biosemiotic constraints on the (biological) functions of (neuro)cognitive systems that serve to restrict the range of functions (neuro)cognitive systems have or are selected for. This turns out to have implications for issues on the convergent evolution of cognitive traits. (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.

Modern Indian nationalist thought has dealt with political ideas such as freedom, equality, liberty, democracy, so on and so forth. The idea of freedom received enough attention on the part of most of the modern Indian political thinkers. However, the idea of freedom as envisaged by the nationalist thinkers did not receive positive response from the other stream of modern Indian thought. Dalit-Bahujan political thinkers questioned the narration of freedom as propagated by the nationalist thinkers. Nationalist thinkers aspired for universal (...) values and at the same time reaffirmed ancient religious principles. Such effort was questioned and doubted by the other thinkers of modern India. Thus, one can find different narrations of freedom, such as social, economic and political. The social categories such as caste, class and gender became bases for their narration on the idea of freedom. The ideas and arguments of B. G. Tilak, M. K. Gandhi, Pandita Ramabai, Jyotiba Phule, B. R. Ambedkar E. M. S. Namboodripad and others would help in larger understanding of the idea of freedom. (shrink)

"This paper aims to impugn the magnified role of specific natural languages in structuring and shaping cognition in the context of language-thought relations. Since language-thought interactions are being increasingly explored in different kinds of empirical studies showing or attempting to show context-specific or general influences of language over thought and thinking, there is reason to tame the excesses of language-specific influences over thought, thinking and cognition. In this regard, any context-specific influences of languages over thought and thinking in being grounded (...) in certain modes/modalities of cognition must be governed by the constraints of body-world interactions that operate on modes/modalities of cognition. Thus, this paper will argue that language-specific influences over thought, thinking and cognition are possible to the extent that they are permitted by the constraints of embodiment.

Natural language meaning has properties of both (embodied) cognitive representations and formal/mathematical structures. But it is not clear how they actually relate to one another. This article argues that how properties of cognitive representations and formal/mathematical structures of natural language meaning can be united remains one of the puzzles in cognitive science. That is primarily because formal/mathematical structures of natural language meaning are abstract, logical, and truth‐conditional properties, whereas cognitive/conceptual representations are embodied and grounded in sensory‐motor systems. After reviewing the (...) current progress, this work offers, in outline, the general formulations that show how these two different kinds of representations for semantic structures can (potentially) be unified and also proposes three desiderata for testing, in brain dynamics, the mathematical equivalence between formal symbolic representations (and their transitions), and neuronal population codes (and their transitions).

This paper revisits the conception of intelligence and understanding as embodied in the Turing Test. It argues that a simple system of meaning relations drawn from words/lexical items in a natural language and framed in terms of syntax-free relations in linguistic texts can help ground linguistic inferences in a manner that can be taken to be 'understanding' in a mechanized system. Understanding in this case is a matter of running through the relevant inferences meaning relations allow for, and some of (...) these inferences are plain deductions and some can serve to act as abductions. Understanding in terms of meaning relations also supervenes on linguistic syntax because such understanding cannot be simply reduced to syntactic relations. The current approach to meaning and understanding thus shows that this is one way, if not the only way, of framing Alan Turing's original insight into the nature of thinking in computing systems.

Medical ethics in the Indian context is closely related to indigenous classical and folk traditions. This article traces the history of Indian conceptions of ethics and medicine, with an emphasis on the Hindu tradition. Classical Ayurvedic texts including Carakasamhita and Susrutasamhita provide foundational assumptions about the body, the self, and gunas, which provide the underpinnings for the ethical system. Karma, the notion that every action has consequences, provides a foundation for medical morality. Conception, prolongation of one's blood-line is an important (...) ethical aim of life. Thus a wide range of practices to further conception are acceptable. Abortion is a more complex matter ethically. At the end of life death is viewed in the context of passage to another life. Death is a relief from suffering to be coped with by the thought of an eternal atman or rebirth. Keywords: India, Hindu, karma, conception, death CiteULike Connotea Del.icio.us What's this? (shrink)

This paper aims to show that properties of cognitive/conceptual representations and formal‐logical structures of linguistic meaning can be inter‐translated, recast, transformed into one another, and so united together, even though cognitive/conceptual representations and formal‐logical structures of linguistic meaning are apparently distinct in ontology and divergent in their form or character. While cognitive/conceptual representations are ultimately rooted in sensory‐motor systems, formal‐logical structures of linguistic meaning are abstractions detached from and independent of the actualized world. This paper sketches out the foundations of (...) how representations of linguistic meaning in terms of cognitive/conceptual structures in Cognitive/Conceptual Semantics can be unified with those in terms of formal‐logical structures in Formal Semantics. This is done by recasting cognitive/conceptual representations in terms of formal‐logical structures of linguistic meaning and re‐encoding formal‐logical structures of linguistic meaning in terms of cognitive/conceptual representations. Then, these two types of semantic representations, thus shown representationally equivalent, will be related to a series of derivations across levels in neuronal networks and dynamics. The general discussion on unifying cognitive/conceptual representations of linguistic meaning with formal‐logical structures is contextualized within the broader context of theorizing in cognitive science.

This paper aims to characterize the relationship between information as defined in the information-theoretic approach and linguistic meaning by way of formulation of computations over the lexicon of a natural language. Information in its information theoretic sense is supposed not to be equivalent to linguistic meaning, whereas linguistic meaning has an intrinsic connection to information as far as the form and structure of the lexicon of a language (in a non-lexicological sense) is concerned. We argue that these two apparently conflicting (...) aspects of the relationship between information and linguistic meaning can be unified by showing that information conserves linguistic meaning, only insofar as computations of a certain kind are defined on the symbolic elements of a lexicon. This has consequences not merely for the nature of lexical learning – natural or artificial or otherwise – but also for the conservation of information in axiomatic systems. (shrink)

Game trees (or extensive-form games) were first defined by von Neumann and Morgenstern in 1944. In this paper we examine the use of game trees for representing Bayesian decision problems. We propose a method for solving game trees using local computation. This method is a special case of a method due to Wilson for computing equilibria in 2-person games. Game trees differ from decision trees in the representations of information constraints and uncertainty. We compare the game tree representation and solution (...) technique with other techniques for decision analysis such as decision trees, influence diagrams, and valuation networks. (shrink)

This book examines linguistic expressions of emotion in intensional contexts and offers a formally elegant account of the relationship between language and emotion. The author presents a compelling case for the view that there exist, contrary to popular belief, logical universals at the intersection of language and emotive content. This book shows that emotive structures in the mind that are widely assumed to be not only subjectively or socio-culturally variable but also irrelevant to a general theory of cognition offer an (...) unusually suitable ground for a formal theory of emotive representations, allowing for surprising logical and cognitive consequences for a theory of cognition. Challenging mainstream assumptions in cognitive science and in linguistics, this book will appeal to linguists, philosophers of the mind, linguistic anthropologists, psychologists and cognitive scientists of all persuasions.

Headteachers in the community schools are responsible for academic and administrative activities. They are considered role models for integrity practices. However, the situation is different on some occasions. For instance, political interest plays more important roles than qualifications, training, work experience, etc., in school affairs. In this context, a qualitative study was carried out in the purposefully selected two schools – an urban and a rural – to explore the elements that influence school integrity practices. Data collected from the schools (...) were analyzed and interpreted. The findings show that nepotism, unhealthy party politics, and impunity influence the school integrity practices in Nepal.

Mitochondrial ATP synthesis, calcium buffering, and trafficking affect neuronal function and survival. Several genes implicated in mitochondrial functions map within the genomic region associated with 22q11.2 deletion syndrome (22q11DS), which is a key genetic cause of neuropsychiatric diseases. Although neuropsychiatric diseases impose a serious health and economic burden, their etiology and pathogenesis remain largely unknown because of the dearth of valid animal models and the challenges in investigating the pathophysiology in neuronal circuits. Mouse models of 22q11DS are becoming valid tools (...) for studying human psychiatric diseases, because they have hemizygous deletions of the genes that are deleted in patients and exhibit neuronal and behavioral abnormalities consistent with neuropsychiatric disease. The deletion of some 22q11DS genes implicated in mitochondrial function leads to abnormal neuronal and synaptic function. Herein, we summarize recent findings on mitochondrial dysfunction in 22q11DS and extend those findings to the larger context of schizophrenia and other neuropsychiatric diseases. (shrink)
