Some Strands of Wittgenstein's Normative Pragmatism
Some Strands of Wittgenstein’s Normative Pragmatism, and Some Strains of his Semantic Nihilism ROBERT B. BRANDOM ABSTRACT WORK TYPE In this reflection I address one of the critical questions this monograph is Article about: How to justify proposing yet another semantic theory in the light of Wittgenstein’s strong warnings against it. I see two clear motives for ARTICLE HISTORY Wittgenstein’s semantic nihilism. The first one is the view that philosophical Received: problems arise from postulating hypothetical entities such as ‘meanings’. To 27–January–2018 dissolve the philosophical problems rather than create new ones, Wittgenstein Accepted: suggests substituting ‘meaning’ with ‘use’ and avoiding scientism in philosophy 3–March–2018 together with the urge to penetrate in one's investigation to unobservable depths. I believe this first motive constitutes only a weak motive for ARTICLE LANGUAGE Wittgenstein’s quietism, because there are substantial differences between English empirical theories in natural sciences and semantic theories in philosophy that KEYWORDS leave Wittgenstein’s assimilation of both open to criticism. But Wittgenstein is Meaning and Use right, on the second motive, that given the dynamic character of linguistic Hypothetical Entities practice, the classical project of semantic theory is a disease that can be Antiscientism removed or ameliorated only by heeding the advice to replace concern with Semantic Nihilism meaning by concern with use. On my view, this does not preclude, however, a Linguistic Dynamism different kind of theoretical approach to meaning that avoids the pitfalls of the Procrustean enterprise Wittgenstein complained about. © Studia Humanitatis – Universidad de Salamanca 2019 R.

A Priori Rules: Wittgenstein on the Normativity of Logic
A Priori Rules: Wittgenstein on the Normativity of Logic Peter Railton The University of Michigan Introduction Like many, I have long been uneasy with the category of the a priori. Perhaps I have simply misunderstood it. It has seemed to me, at any rate, that asserting a claim or principle as a priori is tantamount to claiming that we would be justified in ruling out alternatives in advance, no matter what the future course of experience might hold. Yet in my own case, I have felt it would be mere bluffing were I to lodge such a claim. I certainly could not discover in myself any sense of the requisite authority, nor even any clear idea of where to look for guidance in forming it. Contemplating widely-used examples of "propositions true a priori" did not remove my worry. For a start, there was the shadow of history. A claim like "logical truth is a priori" or "the attribution of rationality is a priori in intentional explanation" kept sounding, to my ears, as if they echoed "the Euclidean geometry of space is a priori" or "the principle of sufficient reason is a priori in physical explanation". And these echoes awakened just sort of the worry that had initially unsettled me: I would pronouce myself satisfied that certain claims, at least, were safe from the threat of contrary experience, just on the eve of developments in our on-going view of the world that would lead a sensible person to want to reopen the question. So I would emerge looking like the (perhaps apocryphal) fellow who claimed, in the wake of the great inventions of the nineteenth century, that the US Patent Office could now be closed, since all the really new ideas had been used up. -

1 Embrace Your Cognitive Bias
1 Embrace Your Cognitive Bias http://blog.beaufortes.com/2007/06/embrace-your-co.html Cognitive Biases are distortions in the way humans see things in comparison to the purely logical way that mathematics, economics, and yes even project management would have us look at things. The problem is not that we have them… most of them are wired deep into our brains following millions of years of evolution. The problem is that we don’t know about them, and consequently don’t take them into account when we have to make important decisions. (This area is so important that Daniel Kahneman won a Nobel Prize in 2002 for work tying non-rational decision making, and cognitive bias, to mainstream economics) People don’t behave rationally, they have emotions, they can be inspired, they have cognitive bias! Tying that into how we run projects (project leadership as a compliment to project management) can produce results you wouldn’t believe. You have to know about them to guard against them, or use them (but that’s another article)... So let’s get more specific. After the jump, let me show you a great list of cognitive biases. I’ll bet that there are at least a few that you haven’t heard of before! Decision making and behavioral biases Bandwagon effect — the tendency to do (or believe) things because many other people do (or believe) the same. Related to groupthink, herd behaviour, and manias. Bias blind spot — the tendency not to compensate for one’s own cognitive biases. Choice-supportive bias — the tendency to remember one’s choices as better than they actually were. -
Biases and Variability from Costly Bayesian Inference
Biases and Variability from Costly Bayesian Inference Arthur Prat-Carrabin1,2, Florent Meyniel3, Misha Tsodyks4,5, and Rava Azeredo da Silveira2,4,6,7,? 1Department of Economics, Columbia University, New York, USA 2Laboratoire de Physique de l’École Normale Supérieure, ENS, Université PSL, CNRS, Sorbonne Université, Université de Paris, France 3Cognitive Neuroimaging Unit, Institut National de la Santé et de la Recherche Médicale, Commissariat à l’Energie Atomique et aux énergies alternatives, Université Paris-Saclay, NeuroSpin center, 91191 Gif/Yvette, France 4Department of Neurobiology, Weizmann Institute of Science, Rehovot, Israel 5The Simons Center for Systems Biology, Institute for Advanced Study, Princeton, USA 6Institute of Molecular and Clinical Ophthalmology Basel 7Faculty of Science, University of Basel ?email: [email protected] Abstract When humans infer underlying probabilities from stochastic observations, they exhibit biases and variability that cannot be explained on the basis of sound, Bayesian manipulations of proba- bility. This is especially salient when beliefs are updated as a function of sequential observations. We introduce a theoretical framework in which biases and variability emerge from a trade-off between Bayesian inference and a cognitive cost of carrying out probabilistic computations. We consider two forms of the cost: a precision cost and an unpredictability cost; these penalize beliefs that are less entropic and less deterministic, respectively. We apply our framework to the case of a Bernoulli variable: the bias of a coin is inferred from a sequence of coin flips. Theoretical predictions are qualitatively different depending on the form of the cost. A precision cost induces overestimation of small probabilities on average and a limited memory of past observations, and, consequently, a fluctuating bias. -
Some Strands of Wittgenstein's Normative Pragmatism, and Some
Some Strands of Wittgenstein’s Normative Pragmatism, and Some Strains of his Semantic Nihilism ROBERT B. BRANDOM §1. Strands of Normative Pragmatism FIRST READ THE TRIUMVIRATE of classical American pragmatists as an I undergraduate, under the tutelage of Bruce Kuklick. He saw them as instituting a vibrant philosophical tradition that was visibly continued not only by C. I. Lewis, but by his students Goodman and Quine. (More controversially, but I believe, also correctly, he further saw the semantic holism Quine shared with Sellars as picking up a central strand of the idealist tradition —represented in the Golden Age by Lewis’s teacher Josiah Royce— with which pragmatism had always been in conversation.) My Doktorvater Richard Rorty then made familiar to me an understanding of pragmatism sufficiently capacious to include such disparate and reciprocally unsympathetic philosophers as the early Heidegger and the later Wittgenstein, as well as Sellars, and Quine’s student Davidson. I came to think of pragmatism as a house with many mansions, comprising a number of more or less closely related but distinct and separable commitments, relating various thinkers in the way Wittgenstein made famous under the rubric of “family resemblances.” Excavating the conceptual antecedents of those various pragmatist views led me to see some of the most central among them as rooted firmly in the thought of the German Idealists, Kant and Hegel —as Peirce and Dewey had explicitly avowed1. Among the most important of these antecedents is a thought that I take it serves as a fundamental orienting insight for the later Wittgenstein. This is the idea that intentionality is through and through a normative phenomenon. -

This work pays its focus on the various fundamental problems of philosophy, relating to Ethics, Metaphysics, Epistemology Logic, and its association with scientific realism. It will also highlight the various facets of these problems and the role of philosophers to point out the various issues relating to human issues. It is widely agreed that philosophy as a multi-dimensional subject that shows affinity to others branches of philosophy like, Philosophy of Science, Humanities, Physics and Mathematics, but this paper also seeks, a philosophical nature towards the universal problems of nature. It evaluates the contribution and sacrifices of the great sages of philosophers to promote the clarity and progress in the field of philosophy. Keywords: wisdom, intelligence, induction, deduction, existence, sensations, aphorism Plato: “He who has a taste for every sort of knowledge and is curious to learn is a philosopher” 1. Introduction All subjects written and unwritten pertaining to some object for analysis. Philosophy is one such subject pertaining to wisdom. Wisdom is different from intelligence, Cunningness, wit, cleverness and being crafty. It is the noblest feature differentiating a man from the animal kingdom. It is this specialty of head and heart that makes a man the crown of creation or the deputy of God on earth as well as the order or decree of the first cause. -
Cognitive Biases and Decision Making: a Literature Review and Discussion of Implications for the US Army ______
______________________________________________________________________ Cognitive Biases and Decision Making: A Literature Review and Discussion of Implications for the US Army ______________________________________________________________________ White Paper Human Dimension Capabilities Development Task Force Capabilities Development Integration Directorate Mission Command Center of Excellence (MC CoE) Executive Summary As the US Army’s strategic and operating environment becomes more diffuse and unpredictable, military professionals will increasingly be expected to make critical decisions under conditions of uncertainty. Research suggests that under such circumstances people are more susceptible to make predictable errors in judgment caused by cognitive biases. In order for the US Army to retain overmatch and remain adaptive and effective amid the complex and ambiguous environment of the future it will be critical to more fully understand cognitive biases and to train, educate and develop US Army personnel and institutions to cope with them appropriately. This paper discusses research on cognitive biases and draws conclusions and recommendations relevant to reducing these biases and improving decision making in the Army. The purposes of the research are to 1) describe key concepts that form the foundation of the heuristics and biases literature, 2) identify attempts to develop theories and models to mitigate biases, 3) identify initiatives implemented by the US Army to address cognitive biases or, more generally, to improve decision making, 4) provide a platform to begin linking research on cognitive biases to the success of the US Army for Force 2025 and Beyond, and 5) suggest avenues for the US Army to pursue to address this issue, including courses of action and topics of future research. Descriptive theories of decision making acknowledge that there are finite bounds to human cognition that frequently result in irrational decisions. -
Psychologism: a Case Study in the Sociology of Philosophical Knowledge/Martin Kusch
PSYCHOLOGISM For most of this century, Western philosophy has been resolutely antinaturalist, and until recently the sharp distinction between the empirical sciences and philosophy seemed almost self-evident: the questions of why they should be separate, and of how they came to be separate, were never asked. These questions are at the heart of Martin Kusch’s groundbreaking study. Antinaturalism rose to dominance in the debate on psychologism among German academic philosophers at the turn of the century. Psychologism, according to received opinion, was decisively refuted by Frege and Husserl. Kusch therefore examines their arguments and, crucially, relates them to the context that shaped that debate and gave those arguments their persuasive force. Drawing on perspectives pioneered by the sociology of scientific knowledge, he reconstructs the dynamics of the psychologism debate; he uncovers its causes and weighs the factors that determined its outcome. What emerges is the fascinating picture of a struggle, between ‘pure’ philosophy and the newly emerging experimental psychology, for academic status, social influence and institutional power. The triumph of antinaturalism, far from being the only logical conclusion, was dependent on historical contingency. Introducing forms of analysis new to the history of philosophy, Psychologism will make fascinating reading for lecturers and students of philosophy, psychology, sociology and cognitive science; it will also stimulate renewed debate on the prospects of antinaturalism at the close of this century. Martin Kusch is Lecturer at the Science Studies Unit of the University of Edinburgh. He is the author of Language as Calculus vs. Language as Universal Medium (1989), and Foucault’s Strata and Fields (1991). -
The Debate on Epistemic and Ethical Normativity
Color profile: Generic CMYK printer profile Composite Default screen THE DEBATE ON EPISTEMIC AND ETHICAL NORMATIVITY Dalibor Reni} 165.15 17.023 Epistemology uses some concepts which are usually understood as normative and evaluative. We talk about what a person should or should not believe or judge in certain epistemic circumstances. We evaluate beliefs or judgments with respect not only to whether they are true, but also to whether they are justified. We evaluate the person’s intellectual qualities and motivations with respect to whether she is reasonable, rational, wise, impartial, and epistemically responsible in general. In certain ways this is comparable to the way we evaluate persons and their actions in ethics. It is true that we cannot simply take it for granted that the epistemic evaluation of beliefs and subjects is one case of ethical evaluation, but they seem to be, at least, analogous. Whether or not epistemic normativity is a case of ethical normativity, there are good reasons to assume that notions like ethics of belief, ethics of inquiry or truth–ethos, which we often come across in epistemology, are relevant for understanding epistemic normativity. The question of ethical factors in epistemology has historically underlain Western epistemology, even if it was not always the main focus of attention. The interest for that topic has been revived in recent years in an unexpected settingthat of analytic epistemology. The debate has reached such a degree of liveliness that some commentators speak of a “value turn” in epistemology.1 The issues discussed are mainly the question of the validity of the traditional deontological concept of epistemic normativity, either in itself or in contrast to its consequentialist alternative, and the question of the relevance of virtue ethics in epistemology (virtue epistemology).
