Knowledge and its Limits presents a systematic new conception of knowledge as a kind of mental stage sensitive to the knower's environment. It makes a major contribution to the debate between externalist and internalist philosophies of mind, and breaks radically with the epistemological tradition of analyzing knowledge in terms of true belief. The theory casts new light on such philosophical problems as scepticism, evidence, probability and assertion, realism and anti-realism, and the limits of what can be known. The arguments are (...) illustrated by rigorous models based on epistemic logic and probability theory. The result is a new way of doing epistemology and a notable contribution to the philosophy of mind. (shrink)

‘What is characteristic of every mental activity’, according to Brentano, is ‘the reference to something as an object. In this respect every mental activity seems to be something relational.’ But what sort of a relation, if any, is our cognitive access to the world? This question – which we shall call Brentano’s question – throws a new light on many of the traditional problems of epistemology. The paper defends a view of perceptual acts as real relations of a subject to (...) an object. To make this view coherent, a theory of different types of relations is developed, resting on ideas on formal ontology put forward by Husserl in his Logical Investigations and on the theory of relations sketched in Smith's "Acta cum fundamentis in re". The theory is applied to the notion of a Cambridge change, which proves to have an unforeseen relevance to our understanding of perception. (shrink)

It will be the thesis of this paper that there are among our mental acts some which fall into the category of real material relations. That is: some acts are necessarily such as to involve a plurality of objects as their relata or fundamenta. Suppose Bruno walks into his study and sees a cat. To describe the seeing, here, as a relation, is to affirm that it serves somehow to tie Bruno to the cat. Bruno's act of seeing, unlike his (...) feeling depressed, his putative thinking-about-Santa-Claus or his musing, abstractedly, about the tallest spy, has at least two fundamenta: it is, as a matter of necessity, dependent for its existence upon both Bruno himself and the cat that he sees. This idea will naturally raise echoes of Russell's doctrine of knowledge by acquaintance. 'I am acquainted with an object', Russell tells us, 'when I have a direct cognitive relation to that object, i. e. when I am directly aware of the object itself' (1918, p. 209). And indeed a distinction in many ways like that between acquaintance and description will find a place within the theory here projected, but there are crucial differences. (shrink)

In what does the sense of a sentential connective consist? Like many others, I hold that its sense lies in rules that govern deductions. In the present paper, however, I argue that a classical logician should take the relevant deductions to be arguments involving affirmative or negative answers to yes-or-no questions that contain the connective. An intuitionistic logician will differ in concentrating exclusively upon affirmative answers. I conclude by arguing that a well known intuitionistic criticism of classical logic fails if (...) the answer "No" is accorded parity with the answer "Yes". (shrink)

The paper presents and discusses the so-called Wrong Kind of Reasons Problem (WKR problem) that arises for the fitting-attitudes analysis of value. This format of analysis is exemplified for example by Scanlon's buck-passing account, on which an object's value consists in the existence of reasons to favour the object- to respond to it in a positive way. The WKR problem can be put as follows: It appears that in some situations we might well have reasons to have pro-attitudes toward objects (...) that are not valuable. Or vice versa: we might have reasons not to have pro-attitudes toward some valuable objects. The paper goes through several attempts to solve (or dissolve) the WKR problem and argues that none of them is fully satisfactory. (shrink)

What are facts, situations, or events? When Situation Semantics was born in the eighties, I objected because I could not swallow the idea that situations might be chunks of information. For me, they had to be particulars like sticks or bricks. I could not imagine otherwise. The first manuscript of “An Investigation of the Lumps of Thought” that I submitted to Linguistics and Philosophy had a footnote where I distanced myself from all those who took possible situations to be units (...) of information. In that context and at that time, this meant Jon Barwise and John Perry. (shrink)

A while ago I pulled the short straw, and became chair of my department. One nice part of the job is to praise people I work with, which I can do sincerely because they are very praiseworthy. I also have to read a lot of praise by others; the familiar things—project evaluations, letters of recommendation, promotion dossiers, and so on and so forth. As a result, I have learnt to attend to praise a little more closely.

It is often claimed that emotions are linked to formal objects. But what are formal objects? What roles do they play? According to some philosophers, formal objects are axiological properties which individuate emotions, make them intelligible and give their correctness conditions. In this paper, I evaluate these claims in order to answer the above questions. I first give reasons to doubt the thesis that formal objects individuate emotions. Second, I distinguish different ways in which emotions are intelligible and argue that (...) philosophers are wrong in claiming that emotions only make sense when they are based on prior sources of axiological information. Third, I investigate how issues of intelligibility connect with the correctness conditions of emotions. I defend a theory according to which emotions do not respond to axiological information, but to non-axiological reasons. According to this theory, we can allocate fundamental roles to the formal objects of emotions while dispensing with the problematic features of other theories. (shrink)

The Metaphysics of Knowledge presents the thesis that knowledge is an absolutely fundamental relation, with an indispensable role to play in metaphysics, philosophical logic, and philosophy of mind and language. Knowledge has been generally assumed to be a propositional attitude like belief. But Keith Hossack argues that knowledge is not a relation to a content; rather, it a relation to a fact. This point of view allows us to explain many of the concepts of philosophical logic in terms of knowledge. (...) Hossack provides a theory of facts as structured combinations of particulars and universals, and presents a theory of content as the property of a mental act that determines its value for getting knowledge. He also defends a theory of representation in which the conceptual structure of a content is taken to picture the fact it represents. This permits definitions to be given of reference, truth, and necessity in terms of knowledge. Turning to the metaphysics of mind and language, Hossack argues that a conscious state is one that is identical with knowledge of its own occurrence. This allows us to characterize subjectivity, and, by illuminating the "I"-concept, allows us to gain a better understanding of the concept of a person. Language is then explained in terms of knowledge, as a device used by a community of persons for exchanging knowledge by testimony. The Metaphysics of Knowledge concludes that knowledge is too fundamental to be constituted by something else, such as one's functional or physical state; other things may cause knowledge, but do not constitute it.

This book is a major attempt to reconcile the empirical basis of linguistic science with the a priori nature of philosophical reasoning. Its purpose is to show how the methods and findings of linguistic science, especially of transformational grammar, can be used to cast light upon central problems of analytic philosophy. After dealing with recent objections to the use of linguistic techniques in philosophy, the author shows, with great force and clarity, how these techniques can be applied to such problems (...) as the analysis of singular terms, the concepts of fact, event, and causality, and the meaning of the word "good.".

John Searle's Speech Acts (1969) and Expression and Meaning (1979) developed a highly original and influential approach to the study of language. But behind both works lay the assumption that the philosophy of language is in the end a branch of the philosophy of the mind: speech acts are forms of human action and represent just one example of the mind's capacity to relate the human organism to the world. The present book is concerned with these biologically fundamental capacities, and, (...) though third in the sequence, in effect it provides the philosophical foundations for the other two. Intentionality is taken to be the crucial mental phenomenon, and its analysis involves wide-ranging discussions of perception, action, causation, meaning, and reference. In all these areas John Searle has original and stimulating views. He ends with a resolution of the 'mind-body' problem. (shrink)

Editorial preface to the fourth edition and modified translation -- The text of the Philosophische Untersuchungen -- Philosophische untersuchungen = Philosophical investigations -- Philosophie der psychologie, ein fragment = Philosophy of psychology, a fragment.

Pour contrer le scepticisme au sujet de la connaissance des valeurs, la plupart soutiennent avec John Rawls qu’une croyance comme celle qu’une action est bonne est justifiée dans la mesure où elle appartient à un ensemble de croyances cohérent, ayant atteint un équilibre réfléchi. Christine Tappolet s’inspire des travaux de Max Scheler et d’Alexius von Meinong pour défendre une conception opposée au cohérentisme. La connaissance des valeurs est affirmée dépendre de nos émotions, ces dernières étant conçues comme des perceptions des (...) valeurs. (shrink)

Even the most cursory reader of Husserl’s writings must be struck by the frequent references to essences (“Wesen”, “Essenzen”), Ideas (“Idee”), kinds, natures, types and species and to necessities, possibilities, impossi- bilities, necessary possibilities, essential necessities and essential laws. What does Husserl have in mind in talking of essences and modalities? What did he take the relation between essentiality and modality to be? In the absence of answers to these questions it is not clear that a reader of Husserl can (...) be said to understand him. (shrink)

What is a fact ? Are there such things ?

There are at least three well-known accounts of value and evaluations which assign a central role to emotions. There is first of all the emotivist view, according to which evaluations express or manifest emotional states or attitudes but have no truth values. Second is the dispositionalist view, according to which to possess a value or axiological property is to be capable of provoking or to be likely to provoke emotional responses in subjects characterised in certain ways. Third, there is an (...) epistemology of values that is sometimes invoked by the naïve realist. If the naïve realist is one for whom evaluations are made true by the possession by objects of monadic, mind-independent axiological properties, then one natural question is: What sort of cognitive access do we have to such properties? These value properties, the realist may say, are properties we come to know of by virtue of our emotions. Emotions, he may say, present value properties to us. One variant of this view is the claim that values are the "formal objects" of emotions. Closely related to these claims is the view that our emotions are appropriate to value properties, or not. Indignation and injustice, it is sometimes said, are related in one or more of these three ways. (shrink)

Keith Hossack's thesis is that knowledge is a conceptually primitive and metaphysically fundamental relation between a mind and a fact. He argues that in terms of the simple relation of knowledge we can analyze central notions of epistemology, of semantics, of modality and a priori knowledge, of psychology, and of linguistics. He does so in a framework that includes a fairly rich faculty psychology and that stresses causation: knowledge can be caused by belief, but because knowledge is simple, it is (...) not any kind of belief. He regards his enterprise as metaphysics, and he proceeds in a rather grand manner. The beginning of his Preface might remind one of the opening paragraphs of Leibniz's The Monadology.If knowledge is a simple relation between minds and facts, then we want to know a bit about facts. Hossack takes facts to consist in universals being instantiated among things. He favours a view of universals as respects in which things resemble each other, but his theory is at least officially silent about which universals exist, leaving that as a matter for scientific inquiry. But he takes metaphysics to be a science. Here he is being coy, and it is worth making out how. Hossack uses multigrade relations; these are relations of no fixed polyadicity that for any natural number n may be instantiated by n things. Vectors are bearers of such relations. The relation among working men of uniting to form a union is a multigrade relation, and the founders of the International Workers of the World are a vector bearing this relation. (shrink)
