According to the traditional analysis of propositional knowledge (which derives from Plato's account in the Meno and Theaetetus), knowledge is justified true belief. This chapter develops the traditional analysis, introduces the famous Gettier and lottery problems, and provides an overview of prospective solutions. In closing, I briefly comment on the value of conceptual analysis, note how it has shaped the field, and assess the state of post-Gettier epistemology.

Originally published in 1940. Firstly, this book seeks to combine epistemology and the new developments of the time in psychology. It holds that no epistemology can be sound if it is psychologically defective, nor can a psychological analysis of knowledge be philosophically naïve. Secondly, it attempts to suggest a single structural pattern underlying every type of cognitive situation. Offering a significant reorientation to epistemological thought of its time, this work considers perception, sense and memory and examines the referential (...) theory of knowledge. It is a lucid and precisely organised reading and analysis of knowledge. (shrink)

First published in 1958, this book focuses on the meaning, interpretation, and use of the verb 'to know'. In our daily lives we are often claiming to know this or not to know that; and it is not therefore surprising that the verb has played a major role in philosophical speculation from Plato down to Bertrand Russell. This book analyses the varying meanings of 'know' in its different operational roles: knowing Jones seems to have a different sort of logic from (...) knowing French or from knowing what to do - and equally from knowing that the earth is round and from knowing how to read music. Knowing something is also different from merely believing it. The main purpose of this book is to elucidate, in a new and original way, this whole question of the logical behaviour of 'know'; but its further and no less important purpose is to show how, once we have grasped the way in which certain key 'know'-statements function, a number of philosophical disputes may be discussed more fruitfully and settled more expeditiously. Some of the analyses offered will be regarded as controversial and will undoubtedly provoke discussion. The style is lucid and economical and technical terms are reduced to a minimum. This work is intended not only for the professional philosopher and the university student, but also for the general reader who is interested in the methods of modern philosophical analysis.

The objective of this paper is to defend the non-reductive thesis of phenomenal consciousness. This paper will give an overview of the arguments for the non-reductive explanation of phenomenal consciousness and justify why the reductionist approach is implausible in the context of explaining phenomenal subjective experience. The debate between reductionist and non-reductionist on the project of demystifying and mystifying phenomenal consciousness is driven by two fundamental assumptions-1) Reductive-Naturalistic Objectivism, 2) Phenomenal Realism. There are several arguments for the irreducibility of phenomenal (...) consciousness; this paper will focus on the inverted spectrum argument, knowledge argument, and the conceivability argument.

This book centers on two trends in contemporary epistemology: (i) the dissatisfaction with the reductive analysis of knowledge and (ii) the popularity of virtue-theoretic epistemologies. The goal is to endorse non-reductive virtue epistemology. Given that prominent renditions of virtue epistemology assume the reductive model, however, such a move is not straightforward—work needs to be done to elucidate what is wrong with the reductive model, in general, and why reductive accounts of virtue epistemology, specifically, are lacking. The first part (...) of the book involves diagnosing the Gettier Problem (perhaps the central challenge for any reductive analysis) and defending that diagnosis against objections. The second part involves applying this diagnosis to prominent versions of (reductive) virtue epistemology. The third and final part of this book explores of what non-reductive virtue epistemology should look like, with the aim of establishing a new form of non-reductive virtue epistemology--a type of non-reductive proper functionalism--that is able draw from the strength of the aforementioned trends and contribute positively to a number of debates and discussions across the discipline and beyond.

This thesis centers on two trends in epistemology: the dissatisfaction with the reductive analysis of knowledge, the project of explicating knowledge in terms of necessary and jointly sufficient conditions, and the popularity of virtue-theoretic epistemologies. The goal of this thesis is to endorse non-reductive virtue epistemology. Given that prominent renditions of virtue epistemology assume the reductive model, however, such a move is not straightforward—work needs to be done to elucidate what is wrong with the reductive model, in (...) general, and why reductive accounts of virtue epistemology, specifically, are lacking. The first part of this thesis involves diagnosing what is wrong with the reductive model and defending that diagnosis against objections. The problem with the reductive project is the Gettier Problem. In Chapter 1, I lend credence to Linda Zagzebski’s grim 1994 diagnosis of Gettier problems by examining the nature of luck, the key component of Gettier problems. In Chapter 2, I vindicate this diagnosis against a range of critiques from the contemporary literature. The second part involves applying this diagnosis to prominent versions of virtue epistemology. In Chapter 3, we consider the virtue epistemology of Alvin Plantinga. In Chapter 4, we consider the virtue epistemology of Ernest Sosa. Both are seminal and iconic; nevertheless, I argue that, in accord with our diagnosis, neither is able to viably surmount the Gettier Problem. Having diagnosed what is wrong with the reductive project and applied this diagnosis to prominent versions of virtue epistemology, the final part of this thesis explores the possibility of non-reductive virtue epistemology. In Chapter 5, I argue that there are three strategies that can be used to develop non-reductive virtue epistemologies, strategies that are compatible with seminal non-reductive accounts of knowledge and preserve our favorite virtue-theoretic concepts.

This collection of essays, originally published in 1970 by Random House, gathers together some of the best initial responses to the problems raised by Edmund Gettier's celebrated critique of the traditional analysis of knowledge. Designed for upper-level courses and seminars in undergraduate philosophy programs and is intended as an introduction to epistemology from the analytic point of view.

Roderick Chisholm has offered a new attempt to define knowledge in the second edition of Theory of Knowledge. The purpose of this paper is to present an objection to that definiton.Here is the proposed definition :D6.4 h is known by 5 =df h is accepted by S; h is true; and h is nondefectively evident for 5.To understand D6.4 we need to know what it is for a proposition to be nondefectively evident for a person. That has the (...) following definition:D6.3 h is nondefectively evident for S=df Either h is sertain for S, or h is evident for S and is entailed by a conjunction of propositions each having for S a basis which is not a basis for any false proposition.There are four technical expressions in D6.3: “entailed,” “certain” “evident,” and “basis.“.

The expectation is fulfilled, but in an unexpected way. 'The first studies toward this book were addressed to topics in the field of ethics' ; but our author, like Wagner composing 'Der Ring des Nibelungen', found himself becoming preoccupied with prolegomena. To these the present volume is wholly devoted. In order to establish its fundamental thesis that valuation is a form of empirical knowledge, two preparatory discussions are called for. An analysis of empirical knowledge in general is (...) one of these; but there is an inquiry properly prior even to this, an examination of the topic of meaning. The articulation of the book is accordingly tripartite; and Book I Meaning and Analytic Truth, Book II Empirical Knowledge, and Book III Valuation are of roughly equal length. (shrink)

ABSTRACT: In this essay I provide one methodology that yields the level of analysis of an alleged knowledge-claim under investigation via its relations to varying gradations of scepticism. Each proposed knowledge-claim possesses a specified relationship with: (i) a globally sceptical argument; (ii) the least sceptical but successful argument that casts it into doubt; and (iii) the most sceptical yet unsuccessful argument, which is conceivably hypothesized to repudiate it but fails to do so. Yielding this specified set of (...) relations, by means of proceeding from global scepticism to (ii) and (iii), increases the chances of identifying the highest evaluative relevancy of the levels of analysis and observation of an alleged knowledge-claim. I argue that the failure to analyse and derive a difference between (i) and (ii) with respect to an alleged knowledge-claim signifies that the claim is grounded within the theoretical framework itself, that the claim lacks specification with regard to content that is analysable via that framework, and the claim is dubious insofar as alternative theoretic frameworks may present greater relevancy to levels of observation. KEYWORDS: knowledge, scepticism, perception, level of observation, magnification level, methodological scepticism. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Martin Heidegger and OntologyEmmanuel Levinas (bio)The prestige of Martin Heidegger 1 and the influence of his thought on German philosophy marks both a new phase and one of the high points of the phenomenological movement. Caught unawares, the traditional establishment is obliged to clarify its position on this new teaching which casts a spell over youth and which, overstepping the bounds of permissibility, is already in vogue. For once, (...) Fame has picked one who deserves it and, for that matter, one who is still living. Anyone who has studied philosophy cannot, when confronted by Heidegger’s work, fail to recognize how the originality and force of his achievements, stemming from genius, are combined with an attentive, painstaking, and close working-out of the argument—with that craftsmanship of the patient artisan in which phenomenologists take such pride. In this study, it is important for us to understand, above all, the true intentions of our author, to illuminate what he thinks really needs to be said, and to surmise what is most critical for him.To get to the heart of Heidegger’s system, it seems fitting to begin with a problem that is generally familiar. We choose the problem of knowledge, a deeper understanding of which takes us to the very threshold of Heidegger’s thought. For this problem, central to modern philosophy, is one of the main obstacles of modern philosophy that Heidegger wishes to surmount. Neo-Kantianism, which takes knowledge as the philosophical problem of the first rank, is the movement against which Heidegger rebels with all his strength. We have, thus, every chance of gaining access to his thought by the main door, so to speak. Once inside the system we will try to trace its outlines, 2 reserving, for a second part of our work, the determination of Heidegger’s place in the history of ideas, especially in the phenomenological movement, as well as of his relations with the philosopher to whom he owes so much—Edmund Husserl. 31In its most general form, the problem of the theory of knowledge has a critical significance. It consists in delineating a domain where knowledge can be certain and in determining the criteria for the legitimate scope of knowledge. But this problem, as normal and as simple as it may appear, has deeper roots. That knowledge should need a criterion at all presupposes that truth is not identical to all that is known and that the course [End Page 11] of things can fail to correspond with the course of thought. “How does knowledge correspond to being?” is a more profound formulation of the problem of knowledge.But we are not going to touch anymore on the primordial phenomenon that generates the problem. The problem of correspondence between thing and thought presupposes a free activity of thought and its isolation in relation to the object. It is precisely this presupposition which renders their harmony and even their contact problematic. “How does the subject take leave of itself to attain the object?” is what the problem of knowledge, in the last analysis, boils down to. Its true source is thus the concept of “subject” as elaborated by modern philosophy. The cogito presided over the subject’s birth. The cogito was the affirmation of the privileged nature of the subject’s immanent sphere, of its unique place in existence; hence, the cogito was the specificity of the subject’s connection to the rest of reality, the sui generis nature which opens up the passage from immanence to transcendence, the passage from ideas contained in the thinking substance to 4 their “formal existence.”The concept of the subject, understood as a substance having a specific position in the entire domain of being, presents us with difficulties of two kinds. First, how do we understand this leave-taking from the self which the thinking substance brings about and which displays an entirely original aspect? Indeed, we could say that thought, in reaching out toward objects, does not actually take leave of itself, since its objects—considered as ideas and contents of thought—are, in a certain sense, already within it. In order to make sense of this paradox, Descartes... (shrink)

In this paper I propose an indubitability analysis of knowledge. The motivation for this analysis is a conviction I have that the Cartesian analysis of knowledge as indubitability is not completely mistaken, although it requires considerable weakening if it is to be satisfactory. My analysis may be contrasted to those which treat knowledge as a species of the genus justified true belief. For although on my analysis, ‘S knows that p’ entails ‘S (...) has a justified true belief that p’, I am not proposing indubitability as a differentia distinguishing knowledge from other members of the genus justified true belief. The situation here is analogous to that of the conceptual relation between vermillion and red: ‘X is vermillion’ entails ‘X is red’, but there is no straightforward differentia which would entitle us to think of vermillion as a species of the genus red. Another point of contrast is that species-of-justified-true-belief analyses start with an analysis which is too weak and strengthen it. My starting point is an analysis which is too strong which I then weaken. (shrink)

Discussion: A New Gettier-Type Refutation of Nozick´s Analysis of Knowledge.

It is all but universally accepted in epistemology that knowledge is factive: S knows that p only if p. The purpose of this thesis is to present an argument against the factivity of knowledge and in doing so develop a non-factive approach to the analysis of knowledge. The argument against factivity presented here rests largely on empirical evidence, especially extant research into visuomotor noise, which suggests that the beliefs that guide everyday motor action are not strictly (...) true. However, as we still want to attribute knowledge on the basis of successful motor action, I argue that the best option is to replace factivity with a weaker constraint on knowledge, one on which certain false beliefs might still be known. In defence of this point, I develop the non-factive analysis of knowledge, which demonstrates that a non-factive constraint might do the same theoretical work as factivity. (shrink)

The subject of this study is a philosophical question and an analysis of knowledge. Philosophical questions are questions that almost everyone deals with in daily life. Philosophy-making activity is a fundamental field of study that belongs to man and his essence. Those who are familiar with these questions have become philosophers. Philosophers are concept friends and have built knowledge by adhering to the use of language. Philosophical knowledge, above all, has a systematic, consistent and logical aspect. (...) This discipline, in which questions are more important than answers, formed the basis of other fields. Philosophical thought laid the basic discipline's groundwork, such as science, religion, politics, and art. In this context, the study will include essential views on the philosophical question and the value of knowledge. (shrink)

Low-carbon technological innovation is the main means to develop a low-carbon economy, and network knowledge sharing and collaborative innovation is an effective model for the development of low-carbon technologies. First of all, this article adopts a decision-making experiment and evaluation laboratory method and interpretation structure model, combines the two methods, extracts the advantages of the two, and discards the shortcomings of the two, thus constructing a new optimized and upgraded interpretation structure model. We give methods to explore the main (...) influencing factors of collaborative innovation of low-carbon technologies for online knowledge sharing. Based on the industrial network knowledge sharing and cooperation network environment, the network evolution game model of network knowledge sharing knowledge collaboration is constructed to study the rewards and punishments, the profit distribution rate, the knowledge potential difference, and the parameter pairing of the network knowledge sharing cooperation network structure in the process of network knowledge sharing and collaborative knowledge innovation. The influence of the network knowledge sharing cooperation strategy is obtained through simulation to change the size of the relevant parameters so that the network knowledge sharing cooperation agent chooses the network evolution game of the sharing strategy to realize the optimal evolutionary stable strategy. According to the simulation results, this article proposes suggestions from the following aspects, aiming to improve the overall knowledge synergy effect of the network knowledge sharing and cooperation network.
