Reality contains information that becomes significances in the mind of the observer. Language is the human instrument to understand reality. But is it possible to attain this reality? Is there an absolute reality, as certain philosophical schools tell us? The reality that we perceive, is it just a fragmented reality of which we are part? The work that the authors present is an attempt to address this question from an epistemological, linguistic and logical-mathematical point (...) of view. (shrink)

Very often reality is identified with our knowledge of it, and in turn our knowledge of reality is identified with the linguistic manner of describing it. It is claimed that the three moments cannot be identified, by pointing out some crucial differences among them obtained through an analysis of the power and limitations of languages and of the manners of acquisition of knowledge.

Wincenty Lutosławski was a multilingual Polish philosopher and author who coined the term 'stylometry'. Originally published in 1930, this book presents the outline of a course in metaphysics delivered by Lutosławski at a variety of academic institutions from 1890 onwards. Numerous aspects of reality are discussed in an effort to form a unified conception of it, from the material world through to abstract spirituality. This book will be of value to anyone with an interest in metaphysics and the development (...) of philosophy. (shrink)

There is at present no publication specifically dedicated to analyzing the philosophical implications of augmented reality, especially regarding knowledge formation, which constitutes a fundamental trait of knowledge society. That is why this volume includes an analysis of the applications and implications of augmented reality. While applications cover diverse fields like psychopathology and education, implications concern issues as diverse as negative knowledge, group cognition, the internet of things, and ontological issues, among others. In this way, it (...) is intended not only to generate answers, but also, to draw attention to new problems that arise with the diffusion of augmented reality. In order to contemplate these problems from diverse perspectives, the auhors are from a variety of fields - philosophy, computer sciencess, education, psychology, and many more. Accordingly, the volume offers varied and interesting contributions which are of interest to professionals from multiple disciplines. (shrink)

The Reality of Knowledge completes a trilogy begun with The Architecture of Knowledge (1980) and Processes of Knowledge (2001). It presents a holistic analysis of knowledge and the reality that is known. The book shows how living things, including humans, construct reality in specific ways that maximize their ability to know it. Different species construct different areas of reality, but they all use the same methods: objectification, categorization, and generalization. Support for this (...) analysis comes from examining certain logical protocols in computer technology, because computer architectures have evolved to emulate human knowledge. (shrink)

I discuss how virtual reality can be used to acquire self-knowledge. Lawlor (Philos Phenomenol Res 79(1):47–75, 2009) and Cassam (Vices of the mind: from the intellectual to the political. OUP, Oxford, 2014) develop inferential accounts of self-knowledge in which one can use imagination to acquire self-knowledge. This is done by actively prompting imaginary scenarios and observing one’s reactions to those scenarios. These reactions are then used as the inferential basis for acquiring self-knowledge. I suggest that (...) the imaginary scenarios can be in principle replaced with scenarios in virtual reality in a way that still provides an inferential basis for self-knowledge. Instead of internal prompting in imagination, I call this external prompting in virtual reality. I discuss the advantages and disadvantages of external prompting. On one hand, external prompting avoids some of the common biases that can intervene with internal prompting in imagination. On the other hand, external prompting comes with some challenges of its own. External prompting might be more time-consuming and might be open to a game-like approach of the agent leading to a different sort of distortion that gets in the way of self-knowledge. I suggest that these are practical challenges, but nevertheless, external prompting seems worthwhile for self-knowledge that is otherwise especially difficult to acquire. (shrink)

This book reformulates the sociological subdiscipline known as the sociology of knowledge. Knowledge is presented as more than ideology, including as well false consciousness, propaganda, science and art.

Shankara was born in the eighth century on the west coast of south India. After devoting himself to yoga practices and meditation, Shankara wrote commentaries on the Bhagavad Gita, some of the Upanishads and other scriptures, and travelled throughout India declaring the oneness of a supreme reality and refuting erroneous philosophical doctrines. He reorganized the ancient, renunciate swami order and established permanent monastic centres in four regions of India: Sringeri in the south, Puri in the east, Dwaraka in the (...) west, and Badrinath in the Himalayas. Shankara lived during an era when Sanatana Dharma was beginning to be more widely emphasized, authoritative leadership was lacking, and conflicting religious sects were promoting a variety of philosophical opinions. His emphasis on the oneness of a supreme reality and the divinity of each person was a harmonizing influence. Besides expounding his non-dualistic views as presented in Self-Knowledge, he also wrote poems and composed hymns to reverently honour a variety of gods and goddesses to inspire and encourage people in all walks of life to be devoted to right living and spiritual practices.

Can humans acquire knowledge of ultimate reality, even significant or comprehensive knowledge? I argue that for all we know we can, and that is so whether ultimate reality is divine or non-divine. My strategy involves arguing that we are ignorant, in the sense of lacking public or shared knowledge, about which possibilities, if any, obtain for humans to acquire knowledge of ultimate reality. This follows from a deep feature of our epistemic situation—that our (...) current psychology strongly constrains what we can conceive about the extent to which human intellectual and other psychological capacities might develop in the future. This mean that many possibilities for such development remain open to us epistemically, including the possibility that we might come to understand vastly more about ultimate reality than we currently do, even if ultimate reality is divine. I also argue that there is room to rationally hope that that is so. (shrink)

Open peer commentary on the target article “Arguments Opposing the Radicalism of Radical Constructivism” by Gernot Saalmann. First paragraph: I appreciate Saalmann’s recognition that “there are considerable differences amongst the authors” and that these “have changed their opinions in the course of time” (§3); but given this, what are the consequences for an outline of the theses of radical constructivism (RC)? Which approach is best for outlining a theory of knowing under these hindering conditions? My suggestion would be to use (...) a method specifically developed for this kind of situation and to present it explicitly, or, if it does not yet exist, to develop one. (shrink)

In the following paper, the author will try to test the meaning of the transcendental approach in respect of the inner changes implied by the idea of quantum gravity. He will firstly describe the basic methodological Kant’s aim, viz. the grounding of a meta-science of physics as the a priori corpus of physical knowledge. After that, he will take into account the problematic physical and philosophical relationship between the theory of relativity and the quantum mechanics; in showing how the (...) elementary ontological and epistemological assumptions of experience result to be changed within them, he will also show the further modifications occurred in the development of the loop quantum gravity. He will particularly focus on the tough problem of the relationship space-matter, in order to settle the decisive question about the possibility of keeping a transcendental approach in the light of quantum gravity. He will positively answer by recalling Cassirer’s theory of the invariants of experience, although he will also add some problematic issues arising from the new physical context. (shrink)

We argue that Halford et al.'s characterisation of relational complexity offers an unadaptive principle in terms of cognitive economy, that its relation with the empirical evidence is highly selective, and that the task behaviours used in support of a multivector processing space are better described by linear serial processes which do not require n-dimensional mappings for their emergence.

Multimedia learning theories suggest presenting associated pieces of information in spatial and temporal contiguity. New technologies like Augmented Reality allow for realizing these principles in science laboratory courses by presenting virtual real-time information during hands-on experimentation. Spatial integration can be achieved by pinning virtual representations of measurement data to corresponding real components. In the present study, an Augmented Reality-based presentation format was realized via a head-mounted display and contrasted to a separate display, which provided a well-arranged data matrix (...) in spatial distance to the real components and was therefore expected to result in a spatial split-attention effect. Two groups of engineering students performed six experiments exploring fundamental laws of electric circuits. Cognitive load and conceptual knowledge acquisition were assessed as main outcome variables. In contrast to our hypotheses and previous findings, the Augmented Reality group did not report lower extraneous load and the separate display group showed higher learning gains. The pre- and posttest assessing conceptual knowledge were monitored by eye tracking. Results indicate that the condition affected the visual relevancy of circuit diagrams to final problem completion. The unexpected reverse effects could be traced back to emphasizing coherence formation processes regarding multiple measurements. (shrink)

In this work the distinguished physical chemist and philosopher, Michael Polanyi, demonstrates that the scientist's personal participation in his knowledge, in both its discovery and its validation, is an indispensable part of science itself. Even in the exact sciences, "knowing" is an art, of which the skill of the knower, guided by his personal commitment and his passionate sense of increasing contact with reality, is a logically necessary part. In the biological and social sciences this becomes even more (...) evident. The tendency to make knowledge impersonal in our culture has split fact from value, science from humanity. Polanyi wishes to substitute for the objective, impersonal ideal of scientific detachment an alternative ideal which gives attention to the personal involvement of the knower in all acts of understanding. His book should help to restore science to its rightful place in an integrated culture, as part of the whole person's continuing endeavor to make sense of the totality of his experience. In honor of this work and his The Study of Man Polanyi was presented with the Lecomte de Noüy Award for 1959. (shrink)

In 1984, John W. Yolton published Perceptual Acquaintance from Descartes to Reid. His most recent book builds on that seminal work and greatly extends its relevance to issues in current philosophical debate. Perception and Reality examines the theories of perception implicit in the work of seventeenth- and eighteenth-century philosophers which centered on the question: How is knowledge of the body possible? That question raises issues of mind-body relation, the way that mentality links with physicality, and the nature of (...) the known world. In contrast to commonsense realism, which suggests that the world is as it appears to be, a more complex theory developed throughout this period. Yolton traces its evolution from Descartes to Kant, via Arnauld, Malebranche, Locke, Berkeley, and Hume. Yolton explains that the new theory postulated two interactive relations between perceivers and the physical world, one physical and causal, the other cognitive. An understanding of this double relation is important for an accurate construction of the history of philosophy. It is also important for contemporary thought because it suggests a way to account for representation (cognitivity) and realism at the same time. (shrink)

Knowledge management is important in the construction industry, but there is a dramatic gap between rhetoric and reality, highlighting mistaken expectations of technology. We report on a case study of a major construction company. The UK construction industry, with scarce academic qualifications, and limited use of IT, depends on knowledge sharing, and, crucially, on tacit knowledge. Economic crisis presents particular problems, and recent trends in work organization have far-reaching implications. The industry depends on human knowledge, (...) with limited systems support. A shared concern for health and safety provides the surest guarantee of sustainability of both knowledge and the company. (shrink)

I contend that a great deal of western philosophical thought is based upon a mistaken assumption, and that is: there is something real that we can know. I argue that, on the contrary, insofar as our experience is of a world that has meaning, this experience is not of the world "as it really is," but of the world as we perceive it through language. The very process of making the world meaningful, or learning about it, is at the same (...) time a mediation of the world. ;Because the self has, for the most part, been conceived as some kind of object, in Part One I discuss the relationship between language and our experience of objects, and our experience of objects in time. In Part Two I examine the two traditional approaches to knowledge, and attempt to show that empiricism yields no knowledge of "reality" and that metaphysics is unmeaningful. I conclude that, while we cannot know what is real, we continue to desire to do so, and so continue to make the world meaningful in various ways. ;In Part Three I claim that the self is something that we cannot know--although we try to know ourselves by telling stories about ourselves to ourselves--and that all attempts to describe the self result in the creation of models. I define 'models' as broad, compelling representations of what the self is, but which are incapable of accommodating one or another obvious feature of human experience. ;In Part Four I apply all of the above to the disciplines of psychology and literary criticism. Specifically, I criticize Stanley Fish's notion of the interpretation of texts, and analyze what is called 'dissociative identity disorder' --a disorder that makes sense only on the assumption that many selves can inhabit a single body. ;Finally, in Part Five, I admit that this entire thesis is nonsense, insofar as it is an attempt to say: "This is how things are." I conclude, however, that there are greater and lesser pieces of nonsense in the world, and that the value of philosophy resides in being able to expose great nonsense as nonsense. (shrink)

A common criticism of Locke’s ideational definition of knowledge is that it contradicts his accounts of knowledge’s reality and sensitive knowledge. Here it is argued that the ideational definiton of knowledge is compatible with knowledge of idea-independent reality. The key is Locke’s notion of the signification. Nominal agreements obtain if and only if the ideas’ descriptive contents are the ground for truth; real agreements obtain only if their total denotation are the grounds for (...) truth. The signification of the ideas determine whether they denote real or fantastical objects. Three types of ideas, simple quality-ideas, modal ideas, and relational ideas, necessarily signify real objects. The fourth type, the ideas of substances, are real only if those particular combinations of qualitites have been perceived to co-exist. Locke’s ideas are intrinsically either real or fantastical and thus, it is argued, his models of truth and knowledge’s reality are far from typical correspondence theories. (shrink)

As a study in the methodology of metaphysics, the book seeks to show that ultimately Reality’s inherent impetus to lawful order serves also to account for its existence. It unfolds a train of thought to show that Reality both exists and has the nature it does for good reason, and specifically because this is somehow for the best.

In this book, Michael Arbib, a researcher in artificial intelligence and brain theory, joins forces with Mary Hesse, a philosopher of science, to present an integrated account of how humans 'construct' reality through interaction with the social and physical world around them. The book is a major expansion of the Gifford Lectures delivered by the authors at the University of Edinburgh in the autumn of 1983. The authors reconcile a theory of the individual's construction of reality as a (...) network of schemas 'in the head' with an account of the social construction of language, science, ideology and religion to provide an integrated schema-theoretic view of human knowledge. The authors still find scope for lively debate, particularly in their discussion of free will and of the reality of God. The book integrates an accessible exposition of background information with a cumulative marshalling of evidence to address fundamental questions concerning human action in the world and the nature of ultimate reality.

As scientific discoveries and technological advances continue to modify our perceptions of reality at an unprecedented rate, the traditional frameworks for understanding and organizing our experience of truth and Knowledge have become less and less adequate. David Rich comes to grips with this problem in his innovative study, which shows how both knowledge and truth are conditioned by experience and explores the dynamics of creativity that generate knowledge.

According to one interpretation of Aristotle’s famous thesis, to say that action is the conclusion of practical reasoning is to say that action is itself a judgment about what to do. A central motivation for the thesis is that it suggests a path for understanding the non-observational character of practical knowledge. If actions are judgments, then whatever explains an agent’s knowledge of the relevant judgment can explain her knowledge of the action. I call the approach to action (...) that accepts Aristotle’s thesis so understood Normativism. There are many reasons to doubt Normativism. My aim in this paper is to defend Normativism from a pair of arguments that purport to show that a normative judgment could not constitute an event in material reality and also the knowledge of such a happening. Both highlight a putative mismatch between the natures of, on the one hand, an agent’s knowledge of her normative judgment and, on the other, her knowledge of her own action. According to these objections, knowledge of action includes (a) perceptual knowledge and (b) knowledge of what one has already done. But knowledge of a normative judgment includes neither. Hence knowledge of action cannot simply be knowledge of a normative judgment. (shrink)

Joseph Bertrand's 1888 evidencing that assignment of a probability depends upon what one chooses to know or not and to control or not, congruent with Grad's 1961 evidencing that statistical entropy depends upon what one deems relevant or not in formalization and measurement, radically undermine common sense realism; mean values are symbols, but symbols of what? For that very reason, recent clever conceptualizations of the quantum measurement process via partial tracing do not restore realism: How could deliberate ignorance generate a (...) reality? Beyond this, Born's and Jordan's quantal wavelike probability calculus, entailing algebraic nonseparability and spacetime nonlocality, blurs “reality” still more radically. Thus information stands out as the master word, with its two reciprocal aspects: knowledge and organization. (shrink)

The text translated, “Das Wissen von fremden Ichen,” bears particular importance for the early phenomenological movement for two reasons. The first is Lipps’ refutation of the theory that knowledge of other selves arises by way of an inference from analogy. Lipps first developed his account of empathy to explain that we tend to succumb to geometric optical illusions because we project living activity into inanimate objects. In sum, Lipps’ groundbreaking article on The Knowledge of Other Egos deserves as (...) much interest from the philosophical community today as it had in the past. The figure of Lipps the philosopher needs to be taken into consideration anew among other much-celebrated proponents of the phenomenological movement. The supporters of that theory, however, demand that we ought to be able to pick out a justification for the existence of objective reality from the fact of our sensations by way of thought alone.

Historians and sociologists chart the consequences of the expansion of knowledge; philosophers of science examine the causes. This book bridges the gap. The focus is on ‘academisation’ — the paradox whereby, as the general public becomes better educated to live and work with knowledge, the ‘academy’ increases its intellectual distance from the public, so that the nature of social and natural reality becomes more rather than less obscure.

This dissertation is about human knowledge of reality. In particular, it argues that scientific knowledge is bounded by historically available instruments and theories; nevertheless, the use of several independent instruments and theories can provide access to the persistent potentialities of reality. The replicability of scientific observations and experiments allows us to obtain explorable evidence of robust entities and properties. The dissertation includes seven chapters. It also studies three cases – namely, Higgs bosons and hypothetical Ϝ-particles (section (...) 2.4), the Ptolemaic and Kepler model of the planets (section 6.7), and the special theory of relativity (chapter 7). -/- Chapter 1 is the introduction of the dissertation. Chapter 2 clarifies the notion of the real on the basis of two concepts: persistence and resistance. These concepts enable me to explain my ontological belief in the real potentialities of human-independent things and the implications of this view for the perceptual and epistemological levels of discussion. On the basis of the concept of “overlapping perspectives”, chapter 3 argues that entity realism and perspectivism are complementary. That is, an entity that manifests itself through several experimental/observational methods is something real, but our knowledge of its nature is perspectival. Critically studying the recent views of entity realism, chapter 4 extends the discussion of entity realism and provides a criterion for the reality of property tokens. Chapter 5, in contrast, develops the perspectival aspects of my view on the basis of the phenomenological-hermeneutical approaches to the philosophy of science. This chapter also elaborates my view of empirical evidence, as briefly expressed in sections 2.5 and 4.5. Chapter 6 concerns diachronic theoretical perspectives. It first explains my view of progress, according to which current perspectives are broader than past ones. Second, it argues that the successful explanations and predictions of abandoned theories can be accounted for from our currently acceptable perspectives. The case study of Ptolemaic astronomy supports the argument of this chapter. Chapter 7 serves as the conclusion of the dissertation by applying the central themes of the previous chapters to the case study of special relativity theory. I interpret frame-dependent properties, such as length and time duration, and the constancy of the speed of light according to realist perspectivism. (shrink)

Imagine a character, Mary Analogue, who has a complete theoretical knowledge of her subject matter: the illusory nature of self. Suppose that when presenting her paper on no self at a conference she suffers stage-fright – a reaction that implies she is under an illusion of the very self whose existence she denies. Might there be something defective about her knowledge of no self? The Buddhist tradition would claim that Mary Analogue, despite her theoretical omniscience, lacks deep ‘insight (...) knowledge’ into the reality of no self. The only way for her to gain insight, and thereby improve her epistemic status, would be to divest her mind of the self-illusion. In this paper, I offer an analysis of what could be epistemically involved in the process of acquiring such insight knowledge whereby one becomes, in Buddhist parlance, ‘awakened’. (shrink)

One of the most widespread claims combining epistemology and metaphysics in post-Avicennian Islamic philosophy was that every object of thought is real. In Muʿtazilite reading, it was endorsed due to a theory of knowledge which states that knowledge is a connection or relation between the knower and the object known. Avicennists accepted it due to the rule that in a proposition “s is p” if p is something positive s has to be positive and real too. Hence, insofar (...) as one can conceptually distinguish between two non-existent items, they have to be real. In this article, the author presents significant consequences of this theory: the acceptance and denial of non-existent yet real extramental objects; the concept of mental existence as an alternative solution; the conceivability of paraconsistent ideas and their reality or reducibility to some real objects.

In the face of various contemporary everyday understandings of work, this essay relies upon phenomenological analyses to distinguish key concepts such as action (Handeln), working (Werken), and work (Arbeit). Actions are pre-planned conscious experiences, working is the embodiment of such actions in behavior, and work is a form of working that has for its principal goal the changing of reality. The concept of work as we know it has evolved from structural developments in society such as the social division (...) of labor, the growth of professions, the social distribution of knowledge, the growth of markets, and industrialization. The end results have been that work roles have been separated from kinship structures, that one produces for society at large rather than one’s own needs, and that one is no longer self-sufficient in the maintenance of one’s lifestyle.

The dominating theologian in Europe between Thomas Aquinas and John Duns Scotus, Henry of Ghent produced a massive Summa of Ordinary Questions as well as fifteen quodlibets during his long tenure at the University of Paris. His work constituted a new synthesis of faith and reason which competed with that of Thomas Aquinas and influenced the history of both philosophy and theology. The first five articles of the Summa, dealing with various issues associated with human knowledge, constitute an adequate (...) introduction to Henry's thought. In them we find his approach to fundamental principles and themes developed in detail in the rest of his corpus. Of the five, only article one has appeared as a whole in English translation. The next four articles reinforce and develop the findings of the first article, providing additional treatments that indicate Henry's principles and orientation. In fact, these four articles alone provide a condensed but remarkably rich portrait of Henry's basic thought, and so are an invaluable resource for beginning and advanced students alike. Articles 2-5 include important positions on knowledge and reality, a conception of humanity's ultimate purpose and the pursuits most conducive to it, and an approach to faith and reason. These four articles are presented here for the first time in English translation with an introduction and notes. Along with the translation, the volume includes the Latin text of the modern critical edition. --Book cover. (shrink)

No one denies that in his research the historian, whether consciously or not, guides himself by already acquired knowledge of reality past and present that has undergone certain interpretation. It is usually said that he possesses a certain "view of the world." a certain understanding of the historical process, a certain theory , i.e., conceptions from which he cannot detach himself in the course of his research. Some regard this situation as a kind of "inevitable evil" inherent primarily (...) in the social sciences and demand "pure," "objective" research, i.e., for historical research, that it not be guided by anything but the sources actually employed. There are others who are not disturbed by this situation, for they recognize that "pure" research does not exist even in the natural sciences. And if they make certain demands in this regard, it is not for elimination of the researcher's particular standpoint, guided by the knowledge already acquired, but rather enrichment and perhaps qualitative reconstruction of the knowledge he employs in his research. This knowledge is treated in the given case as a kind of governing mechanism in the process of research. The proponents of both points of view strive for a particular goal: attainment of research results as adequate to reality as possible in a given field, with the only difference that they suggest different paths for attainment of this goal. It may even be stated that these standpoints are not debatable, for adherents of the second point of view will undoubtedly agree that in order to enrich and perhaps reorganize the knowledge used in the research it is necessary to eliminate from it elements of low quality, i.e., speculative, unsupported knowledge that impedes the research. Adherents of the former point of view, however, would not maintain too extreme a position if the knowledge they want to eliminate proves to be scientific knowledge, i.e., confirmed knowledge or, to put it differently, true knowledge. Naturally, this does not mean that no differences exist between these viewpoints. (shrink)

In this paper, I argue that arguments from skeptical hypotheses for external world skepticism derive their support from a skeptical argument from the distinction between appearance and reality. This skeptical argument from the appearance/reality distinction gives the external world skeptic her conclusion without appealing to skeptical hypotheses and without assuming that knowledge is closed under known entailments. If this is correct, then this skeptical argument from the appearance/reality distinction poses a new skeptical challenge that cannot be (...) resolved by denying skeptical hypotheses or knowledge closure.

The thesis that knowledge is a factive mental state plays a central role in knowledge-first epistemology, but accepting this thesis requires also accepting an unusually severe version of externalism about the mind. On this strong attitude externalism, whether S is in the mental state of knowledge can and often will rapidly change in virtue of changes in external states of reality with which S has no causal contact. It is commonly thought that this externalism requirement originates (...) in the factivity of knowledge. However, despite a number of recent defenses of non-factive accounts of knowledge, epistemology has yet to consider whether a non-factive approach might produce a version of the mental state thesis that can avoid strong externalism. Here I do just that, exploring how three different proposals for weakening factivity might be adapted to theories of knowledge as a non-factive mental state. Contrary to what we might expect, however, none of these proposals are compatible with anything close to attitude internalism about knowledge—or even a substantially weaker externalism. All told, the widespread view that wraps up the severe externalism required for knowledge to be a mental state in factivity is mistaken. Knowledge’s external-world connection runs far deeper than the factivity constraint. (shrink)

This monograph addresses the question of the increasing irrelevance of philosophy, which has seen scientists as well as philosophers concluding that philosophy is dead and has dissolved into the sciences. It seeks to answer the question of whether or not philosophy can still be fruitful and what kind of philosophy can be such. The author argues that from its very beginning philosophy has focused on knowledge and methods for acquiring knowledge. This view, however, has generally been abandoned in (...) the last century with the belief that, unlike the sciences, philosophy makes no observations or experiments and requires only thought. Thus, in order for philosophy to once again be relevant, it needs to return to its roots and focus on knowledge as well as methods for acquiring knowledge. Accordingly, this book deals with several questions about knowledge that are essential to this view of philosophy, including mathematical knowledge. Coverage examines such issues as the nature of knowledge; plausibility and common sense; knowledge as problem solving; modeling scientific knowledge; mathematical objects, definitions, diagrams; mathematics and reality; and more. This monograph presents a new approach to philosophy, epistemology, and the philosophy of mathematics. It will appeal to graduate students and researchers with interests in the role of knowledge, the analytic method, models of science, and mathematics and reality. (shrink)

If there is any consensus about knowledge in contemporary epistemology, it is that there is one primary kind: knowledge-that. I put forth a view, one I find in the works of Aristotle, on which knowledge-of – construed in a fairly demanding sense, as being well-acquainted with things – is the primary, fundamental kind of knowledge. As to knowledge-that, it is not distinct from knowledge-of, let alone more fundamental, but instead a species of it. To (...) know that such-and-such, just like to know a person or place, is to be well-acquainted with a portion of reality – in this case a fact. In part by comparing classic Gettier cases to cases in which one has true impressions of but fails to know a person, I argue that this account not only respects our intuitions about knowledge-that – in particular that it is or entails non-accidentally true justified belief – but also explains them, providing a compelling analysis.

In our post-modern cultural climate we are often told that reality is value-free. Indeed sometimes it is even said to be fact-free. Yet almost all philosophers have been deeply concerned with matters of value, in addition to their other main pre-occupation: that is the nature of truth and our knowledge of it. The question therefore arises: why should these two – good and truth – be so powerfully connected? And why should this business of value continue to exert (...) the hold on philosophers that it evidently does? (shrink)
