Social Thought in Indic Civilization presents an interdisciplinary perspective on the pre-colonial social thought. It draws on the methodologies and research traditions of history, political science and sociology to look at major themes and social processes to provide a comprehensive understanding of the society in the historical setting contextualized in the social and political relations of the time. The arguments, facts, themes and interpretations presented in the book are usually not found in the mainstream academic narratives. This book explores a (...) range of key themes such as non-violence in religious praxis; dharma in Indic social traditions; medicinal concepts and institutions; ideas and praxis of Shastrarth; knowledge traditions and institutions; music traditions; and Stritva in texts and praxis. This study highlights the impact of colonial rule on the 'construction of knowledge' from a Western (colonial) perspective and how it ignored the importance of Indian political thought of the pre-colonial period.

In this book, Sorensen presents the first general theory of the thought experiment. He analyses a wide variety of thought experiments, ranging from aesthetics to zoology, and explores what thought experiments are, how they work, and what their positive and negative aspects are. Sorensen also sets his theory within an evolutionary framework and integrates recent advances in experimental psychology and the history of science.

Using labelled formulae, a cut-free sequent calculus for intuitionistic propositional logic is presented, together with an easy cut-admissibility proof; both extend to cover, in a uniform fashion, all intermediate logics characterised by frames satisfying conditions expressible by one or more geometric implications. Each of these logics is embedded by the Gödel–McKinsey–Tarski translation into an extension of S4. Faithfulness of the embedding is proved in a simple and general way by constructive proof-theoretic methods, without appeal to semantics other than in the (...) explanation of the rules. (shrink)

This text maps the network of concepts that constitute the general catagory of reason. In the process it shows that some famous philosophical doctrines are based on mistaken assumptions in this conceptual area. In particular, it aims to undermine the arguments of Hume and is modern followers to the effect that reason can be theoretical but not practical (can govern thought but not action) and that value judgements cannot be validly inferred from facts.

The paper deals with the early Yogācāra strategies for explaining intersubjective agreement under a ‘mere representations’ view. Examining Vasubandhu, Asaṅga, and Sthiramati’s use of the example of intersubjective agreement among the hungry ghosts, it is demonstrated that in contrast to the way in which it was often interpreted by contemporary scholars, this example in fact served these Yogācāra thinkers to perform an ironic inversion of the realist premise—showing that intersubjective agreement not only does not require the existence of mind-independent objects (...) but is in fact incompatible with their existence. By delineating the phenomenological complexity underlying this account, the paper then proceeds to unpack the emergent Yogācāra account of intersubjectivity, its implications on the understanding of being, the life-world, and alterity, arguing that it proposes a radical revision of the way we conceive of the ‘shared’ and ‘private’ distinction in respect to experiences, both ordinarily and philosophically.

Can the early Yogācāra be said to present a systematic theory of meaning? The paper argues that Sthiramati’s bhāṣya on Vasubandhu’s Triṃśikā, in which he argues that all language-use is metaphorical, indeed amounts to such a theory, both because of the text’s engagement with the wider Indian philosophical conversation about reference and meaning and by virtue of the questions it addresses and its motivations. Through a translation and analysis of key sections of Sthiramati’s commentary I present the main features of (...) this theory of meaning and discuss the ways in which it is distinct from Vasubandhu’s ideas. I demonstrate how this theory of meaning enabled Sthiramati to present a unique understanding of discourse that distinguishes between varying levels of truth within the conventional realm. This understanding sat well with the Yogācāra soteriological and theoretical needs, and most importantly, enabled him to establish the meaningfulness of the school’s own metaphysical discourse. Securing this meaningfulness was especially important to Sthiramati in meeting the challenge posed by the radical conventionalism of the Madhyamaka, and his response as I interpret it suggests that one of the main disputes between the early Yogācāra with the Mādhyamika, at least as reflected in the Triṃśikā-bhāṣya, in fact turns on linguistic rather than ontological issues.

Though dividing one’s attention between two input streams typically impairs performance, detecting a behaviorally relevant stimulus can sometimes enhance the encoding of unrelated information presented at the same time. Previous research has shown that selection of this kind boosts visual cortical activity and memory for concurrent items. An important unanswered question is whether such effects are reflected in processing quality and functional connectivity in visual regions and in the hippocampus. In this fMRI study, participants were asked to memorize a stream (...) of naturalistic images and press a button only when they heard a predefined target tone. Images could be presented with a target tone, with a distractor tone, or without a tone. Auditory target detection increased activity throughout the ventral visual cortex but lowered it in the hippocampus. Enhancements in functional connectivity between the ventral visual cortex and the hippocampus were also observed following auditory targets. Multi-voxel pattern classification of image category was more accurate on target tone trials than on distractor and no tone trials in the fusiform gyrus and parahippocampal gyrus. This effect was stronger in visual cortical clusters whose activity was more correlated with the hippocampus on target tone than on distractor tone trials. In agreement with accounts suggesting that subcortical noradrenergic influences play a role in the attentional boost effect, auditory target detection also caused an increase in locus coeruleus activity and phasic pupil responses. These findings outline a network of cortical and subcortical regions that are involved in the selection and processing of information presented at behaviorally relevant moments. (shrink)

The argument proceeds by exploiting the gradually decreasing vagueness of a certain sequence of predicates. the vagueness of 'vague' is then used to show that the thesis that all vague predicates are incoherent is self-defeating. a second casualty is the view that the probems of vagueness can be avoided by restricting the scope of logic to nonvague predicates.

A Brief History of the Paradox is the first narrative history of paradoxes. Sorenson draws us deep inside the tangles of riddles, paradoxes and conundrums by answering the questions which are seemingly unanswerable. Can God create a stone too heavy for him to lift? Can time have a beginning? Which came first, the chicken or the egg? Filled with illuminating anecdotes, A Brief History of the Paradox is vividly written and will appeal to anyone who finds trying to answer unanswerable (...) questions a paradoxically pleasant endeavour.

Do we need light to see? I argue that the black experience of a man in a perfectly dark cave is a representation of an absence of light, not an absence of representation. There is certainly a difference between his perceptual knowledge and that of his blind companion. Only the sighted man can tell whether the cave is dark just by looking. But perhaps he is merely inferring darkness from his failure to see. To get an unambiguous answer, I switch (...) the focus from perceptual knowledge to non-epistemic seeing. My conclusion is that we see even in the limiting case of absolute darkness - regardless of whether we believe we are seeing. We see little of pratical interest. But in terms of basic information, we see about as much as we do when the lights are on. Depending on what has gone before and after, we may even see ordinary objects. (shrink)

The problem of determinism arises in all the major areas of philosophy. The first part of this book, first published in 1991, is a critical and historical exposition of the problem and the most important ideas and arguments which have arisen over the many years of debate. The second part considers the various forms of determinism and the implications that they engender.

Suppose you have an infinite past. If you had banked the spare dollar you have always had, then the interest would have made you rich by now. Your procrastination is inexcusable. But what should you have done? At any time at which you invest the dollar you would regret not investing it earlier. Satisficers can solve prospective puzzles involving infinite choice but cannot solve this retrospective puzzle about regret. A moral version of the puzzle suggests that there can be inevitable (...) moral failure. It does so without appeal to moral luck, moral dilemmas or original sin. (shrink)

The current spread of coronavirus has caught our modern world by surprise, which leads to widespread panic, fear and confusion. However, if we view the unfolding of these events from a scientific historical perspective of past human evolution, we may discover the reoccurring patterns of the environmental conditions that give rise to such epidemics. Hence, we can figure out better methods to prepare and react to the infectious agents that spread diseases that have shaped the course of human history before. (...) Here, I propose a holistic view of human evolution, with an interdisciplinary approach that studies how cyclic variation in solar UV energy affects the evolution of viruses and shapes the symbiotic dynamics of human life on earth.

The eighteenth century saw the publication of many scientific and technical dictionaries, particularly in France, one of the most important being P. J. Macquer's Dictionnaire de chymie. Both the original text of 1766 and the revised and enlarged version of 1778 were translated into several languages, sometimes with authoritative notes and additions by the translators. No mere list of definitions, Macquer's work contained long articles that made it a comprehensive treatise on chemistry, and it set the pattern for many subsequent (...) chemical dictionaries. We have endeavoured to give an account of the circumstances in which the various editions, reprints and translations were published, and we add detailed bibliographical descriptions of them. Bibliographical purists consider that all the copies of a book printed from the same setting of type constitute an ‘edition’, and that there is a new edition when all or most of the type has been reset. However, Macquer described his revised and expanded text of 1778 as the ‘second edition’ and this designation has been adopted by subsequent writers, even though the original text was reprinted several times from different settings of type before 1778. In order to avoid confusion we therefore refer to all versions of the 1766 and 1778 editions as ‘issues’, ‘printings’ or ‘reprints’ of the first and second edition respectively. (shrink)

Kripshe treats ‘god’ as an empty natural kind term such as ‘unicorn’. She applies Saul Kripke's fresh views about empty natural kinds to ‘god’. Metaphysically, says Kripshe, there are no possible worlds in which there are gods. Gods could not have existed, given that they do not actually exist and never did. Epistemologically, godlessness is an a posteriori discovery. Kripshe dismisses the gods in the same breath that she dismisses mermaids. Semantically, the perspective Kripshe finds most perspicacious, no counterfactual situation (...) is properly describable as one in which there are gods. Perhaps it is not quite a necessary truth that there are no gods. According to Saul Kripke, failed natural kind terms are ill-defined. Incorporating ill-defined terms into declarative sentences yields only mock propositions. Just as the meteorologist has no professional interest in mock thunder, the logician has no professional interest in mock propositions. Kripshe disagrees with agnostics who assign a low probability to ‘There is at least one god’. The bearers of probabilities must be propositions. Despite this deference to science, Kripshe agrees with the a priori atheist that, necessarily, no future experience could constitute an encounter with a god. Divine revelation is impossible. Kripshe's a posteriori necessary atheism compares favorably to familiar forms of atheism and to non-cognitivists. It reveals interesting challenges to a coherent formulation of atheism. (shrink)

Islamic building codes require mosques to face Mecca. The further Islam spreads, the more apt are believers to fall into a quandary. X faces Y only when the front of X is closer to Y than any other side of X. So the front of the mosque should be oriented along a shortest path to Mecca. Which way is that? Does the path to Mecca tunnel through the earth? Or does the path follow the surface of the earth?

History is the science which investigates the successive changes that have taken place in the material and intellectual conditions of man; it inquires into the causes of those changes, and the influence which they have exerted in modifying the life and mind of mankind.

Do not pass by my epitaph, Wayfarer, but when you have stopped, hear and learn, then depart. There is no boat, To carry you to Hades, No ferryman Charon, No judge Aeacus, No Dog Cerberus.

Sorensen provides a panoramic view of paradoxes of theoretical and practical rationality. These puzzles are organized as apparent counterexamples to attractive principles such as the principle of charity, the transitivity of preferences, and the principle that we should maximize expected utility. The following paradoxes are discussed: fearing fictions, the surprise test paradox, Pascal’s Wager, Pollock’s Ever Better wine, Newcomb’s problem, the iterated prisoner’s dilemma, Kavka’s paradoxes of deterrence, backward inductions, the bottle imp, the preface paradox, Moore’s problem, Buridan’s ass, Condorcet’s (...) paradox of cyclical majorities, the St. Petersburg paradox, weakness of will, the Ellsberg paradox, Allais’s paradox, and Peter Cave’s puzzle of self-fulfilling beliefs.

Stepping into the other guy's shoes works best when you resemble him. After all, the procedure is to use yourself as a model: in goes hypothetical beliefs and desires, out comes hypothetical actions and revised beliefs and desires. If you are structurally analogous to the empathee, then accurate inputs generate accurate outputs-just as with any other simulation. The greater the degree of isomorphism, the more dependable and precise the results. This sensitivity to degrees of resemblance suggests that the method of (...) empathy works best for average people. The advantage of being a small but representative sample of the population will create a bootstrap effect. For as average people prosper, there will be more average descendants and so the degree of resemblance in subsequent generations will snowball. Each increment in like-mindedness further enhances the reliability and validity of mental simulation. With each circuit along the spiral, there is tighter and tighter bunching and hence further empowerment of empathy. The method is self-strengthening and eventually molds a population of hyper-similar individuals-which partly solves the problem of other minds. (shrink)

One familiar philosophical use of the term ‘evil’ just contrasts it with ‘good’, i.e., something is an evil if it is a bad thing, one of life’s “minuses.” This is the sense of ‘evil’ that is used in posing the traditional theological problem of evil, though it is customary there to distinguish between moral evils and natural evils. Moral evils are those bad things that are caused by moral agents; natural evils are those bad things that are not caused by (...) moral agents. Since the existence of evils of both sorts is usually taken to be indubitable, the problem of evil is then construed as the problem of how to square their existence with the existence of an all-powerful and benevolent God.

This paper presents a new argument against philosophical theories based on arguments in favor of ontological reductions. The argument is an experiment in thought that has transcendental force, because it demonstrates the impossibility of forming a concept of anything with a reductionist nature. So although we consider as examples only theories that try to reduce everything in accordance with the currently popular materialisms or dualism, the argument applies as well to every sort of reduction theory whatever.

_Der Mythos der religiösen Neutralität_ bietet eine radikale Neuinterpretation der allgemeinen Beziehungen zwischen Religion, Wissenschaft und Philosophie.

Although they hold different political positions, Oakeshott and Dunn actually share in common a sceptical reading of the human condition and the nature of politics. There are, however, two sceptical traditions within the British context that they seem, respectively, to have followed: the Humean autonomy of practice and the Lockean quest for guidance. It is hoped that by tracing their sources back to Hume and Locke, Oakeshott's and Dunn's conflicting views on the theory of practical reason, namely the detachment view (...) versus the engagement view, can be well explicated, and that the differentia between the `right' and the `left' can be philosophically reconsidered.

Semantic indeterminacy is the ether of philosophy of language. It fills the interstices of our intentions and pervades accounts of presupposition, tense, fiction, translation, and especially, vagueness. Yet semantic indeterminacy is as impossible as ectoplasm. Indeed, more so! The demonstration need only borrow a few assumptions used elsewhere in widely accepted impossibility results. Since an impossibility is never a necessary condition for anything actual, semantic indeterminacy must be superfluous. Language is no more explained by semantic indeterminacy than calculus is explained (...) by (pre-Robinsonian) infinitesimals. (shrink)
