Besides seeing a rabbit or seeing that the rabbit is grayish, do we also sometimes see barely just the particular animal (not as an animal or as anything) or the feature rabbitness or grayness? Such bare, nonverbalizable perception is called "indeterminate perception" (nirvikalpaka pratyakṣa) in Nyāya. Standard Nyāya postulates such pre-predicative bare perception in order to honor the rule that awareness of a qualified entity must be caused by awareness of the qualifier. After connecting this issue with the Western debate (...) concerning the "myth of the given," seven distinct arguments are presented showing that the very notion of such indeterminate perception is epistemically otiose and that the Nyāya theory of perception is better off without it.

Witnessing the fate of the various definitions of truth, Donald Davidson has recently called the very drive to define truth a “folly.” Before him, Kant and Frege had given independent arguments why a general definition of truth is impossible. After a quick summary of their arguments, I recount several reasons that Gangeśa gave for not counting truth as a genuine natural universal. I argue that in spite of defining truth as a feature of personal and ephemeral awareness episodes, the Nyāya (...) ya realists such as Gangeśa could maintain that truth is independent of recognition of truth. In the course of my argument, I also show that Roy Perrett’s alleged proof against realism does not succeed. I conclude that realism does not need nonmental atemporal truth-bearers (propositions) which are eternally wholly true (or wholly false), and that knowledge-independence from truths and things can be shown without admitting the existence of unknowable things or truths.

The phenomenon of consciousness has always been a central question for philosophers and scientists. Emerging in the past decade are new approaches to the understanding of consciousness in a scientific light. This book presents a series of essays by leading thinkers giving an account of the current ideas prevalent in the scientific study of consciousness. The value of the book lies in the discussion of this interesting though complex subject from different points of view ranging from physics, computer science to (...) the cognitive sciences. Reviews of controversial ideas related to the philosophy of mind from western and eastern sources including classical Indian first person methodologies provide a breadth of coverage that has seldom been attempted in a book before. Additionally, chapters relating to the new approaches in computational modelling of higher order cognitive function and consciousness are included. The book is of great value for established as well as young researchers from a wide cross-section of interdisciplinary scientific backgrounds, aiming to pursue research in this field, as well as an informed public. * Presents the latest developments in the scientific study of consciousness * Critically reviews different theoretical and philosophical explanations related to the subject * An important book for both students and researchers in designing research projects on consciousness.

We investigate how a group of players might cooperate with each other within the setting of a non-cooperative game. We pursue two notions of partial cooperative equilibria that follow a modification of Nash’s best response rationality rather than a core-like approach. Partial cooperative Nash equilibrium treats non-cooperative players and the coalition of cooperators symmetrically, while the notion of partial cooperative leadership equilibrium assumes that the group of cooperators has a first-mover advantage. We prove existence theorems for both types of equilibria. (...) We look at three well-known applications under partial cooperation. In a game of voluntary provision of a public good we show that our two new equilibrium notions of partial cooperation coincide. In a modified Cournot oligopoly, we identify multiple equilibria of each type and show that a non-cooperator may have a higher payoff than a cooperator. In contrast, under partial cooperation in a symmetric Salop City game, a cooperator enjoys a higher return. (shrink)
It has been well established in literature that small industry clusters (SICs) have an impressive record of innovation and knowledge transmission. This paper explores the possibilities in this regard in third-world clusters through an empirical study of three SICs in India. The paper first examines the essential reasons for the survival and growth of clusters temporally over centuries. Then, it critically assesses the factors that threaten the clusters at present—some of which, it appears, might actually be fatal for these clusters. (...) And finally, the paper concludes that though an enhancement in capacity to innovate and transfuse knowledge would contribute to the sustenance of these clusters, this cannot happen unless decisive intervention occurs to preserve and sustain the fundamental strengths of these clusters.

Some ten years ago an interesting discussion took place in the pages of this journal. It began with an article by Arindam Chakrabarti (2000) whose title betrays its intention: "Against Immaculate Perception: Seven Reasons for Eliminating Nirvikalpaka Perception from Nyāya." There followed a response by Stephen H. Phillips (2001), "There's Nothing Wrong with Raw Perception: A Response to Chakrabarti's Attack on Nyāya's Nirvikalpaka Pratyakṣa," which in turn was commented upon in Chakrabarti's "Reply to Stephen Phillips" (2001).This discussion, (...) as is clear from the titles, concerns the need and even possibility of nirvikalpaka perception. What Chakrabarti tries to do is "to show why we can easily do without .. (shrink)
According to Bikas Chakrabarti (2005, p. 225), the term econophysics was neologized in 1995 at the second Statphys-Kolkata conference in Kolkata (formerly Calcutta), India by the physicist H. Eugene Stanley, who was also the first to use it in print (Stanley, 1996). Mantegna and Stanley (2000, pp. viii-ix) define “the multidisciplinary field of econophysics” as “a neologism that denotes the activities of physicists who are working on economics problems to test a variety of new conceptual approaches deriving from the (...) physical sciences.” The list of such problems has included distributions of returns in financial markets (Mantegna, 1991; Levy and Solomon, 1997; Bouchaud and Cont, 1998; Gopakrishnan, Plerou, Amaral, Meyer, and Stanley, 1999; Sornette and Johansen, 2001; Farmer and Joshi, 2004) the distribution of income and wealth (Drăgulescu and Yakovenko, 2001; Bouchaud and Mézard, 2000; Chatterjee, Yarlagadda, and Charkrabarti, 2005), the distribution of economic shocks and growth rate variations (Bak, Chen, Scheinkman, and Woodford, 1993; Canning, Amaral, Lee, Meyer, and Stanley, 1998), the distribution of firm sizes and growth rates (Stanley, Amaral, Buldyrev, Havlin, Leschhorn, Maass, Salinger, and Stanley, 1996; Takayasu and Okuyama, 1998; Botazzi and Secchi, 2003), the distribution of city sizes (Rosser, 1994; Gabaix, 1999), and the distribution of scientific discoveries (Plerou, Amaral, Gopakrishnan, Meyer, and Stanley, 1999; Sornette 1 and Zajdenweber, 1999), among other problems, all of which are seen at times not to follow normal or Gaussian patterns that can be described fully by mean and variance. The main sources of conceptual approaches from physics used by the econophysicists have been from models of statistical mechanics (Spitzer, 1971), geophysical models of earthquakes (Sornette, 2003), and “sandpile” models of avalanches, the latter involving self-organized criticality (Bak, 1996). An early physicist to assert the essential identity of statistical methods used in physics and the social sciences was Majorana (1942). A common theme among those who identify themselves as econophysicists is that standard economic theory has been inadequate or insufficient to explain the non-Gaussian distributions empirically observed for various of these phenomena, such as “excessive” skewness and leptokurtotic “fat tails” (McCauley, 2004)..

This paper aims to critically discuss the versatility of Popper’s theory of three worlds in the analysis of issues related to the ontological status and character of technical artifacts. Despite being discussed over years and hit with numerous criticisms it is still little known that Popper’s thesis has an important bearing on the philosophical characterization of technical artifacts. His key perspectives on the reality, autonomy, and ontological status of artifacts are rarely taken into consideration by scholars known to be engaged (...) in the study of artifacts. This paper consists of two main sections. The first section attempts to present a critical exposition of Popper’s account of reality and (partial) autonomy of artifacts. Recent discussions about the longstanding distinction between natural objects and artifacts are brought up and the relevance of Popper’s pluralistic thesis to this debate is pointed out. In addition, attention is drawn towards how to read his notion of the autonomy of artifacts. The primary emphasis of the second section is the ontological position of artifacts. Two separate arguments are posed to challenge the dual ontological status of what Popper called ‘embodied’ World 3 objects or artifacts. The first argument is concerned with the material composition and characteristic features of artifacts. The second one addresses the creative and epistemic value of these artificial products.

In a 2009 article Dipesh Chakrabarty argues that "climate change poses for us a question of a human collectivity, an us, pointing to a figure of the universal that escapes our capacity to experience the world . . . a universal that arises from a shared sense of a catastrophe."1 In other words, while Subaltern Studies scholars have been attempting to uncover unique histories independent of the universalizing narrative of European historicism, humanity has become irrevocably universalized as a force of (...) nature whose ecological impact has ushered in the Anthropocene epoch, and no amount of decolonizing the past will help us to escape our shared future: "[There] are no lifeboats here for the rich and the privileged," ..
