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)

The Identity Thesis, proposed by Reid for the case of sensations, and extended by Brentano to conscious states generally, says that a state is conscious iff it is identical with introspective knowledge of its own instantiation. The Thesis offers simple explanations of a number of puzzling features of introspective self-knowledge, and unites the problems of introspection, consciousness and knowledge in the single problem of the metaphysical nature of conscious states. It does nothing to solve the latter problem, but it does (...) entail that a functionalist account of consciousness is incomplete without an exact functionalist definition of knowledge itself.

Atomism denies that complexes exist. Common-sense metaphysics may posit masses, composite individuals and sets, but atomism says there are only simples. In a singularist logic, it is difficult to make a plausible case for atomism. But we should accept plural logic, and then atomism can paraphrase away apparent reference to complexes. The paraphrases require unfamiliar plural universals, but these are of independent interest; for example, we can identify numbers and sets with plural universals. The atomist paraphrases would fail if plurals (...) presuppose complexes: but an Appendix shows that reference to complexes is not required in the semantics of plurals. (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 paper develops an account of consciousness in action. Both consciousness and action are related to knowledge. A voluntary action is defined as a volition, or something intentionally effected by means of such volitions. Volitions are conscious mental acts whose proper function is to make their content true. A mental act is the exercise of a power of mind and a conscious mental act is identical with knowledge of its own phenomenal character. This set of definitions elucidates the relations between (...) consciousness, action and knowledge. (shrink)

The state of affairs of some things falling under a predicate is supposedly a single entity that collects these things as its constituents. But whether we think of a state of affairs as a fact, a proposition or a possibility, problems will arise if we adopt a plural logic. For plural logic says that any plurality include themselves, so whenever there are some things, the state of affairs of their plural self-inclusion should be a single thing that collects them all. (...) This leads to paradoxes analogous to those that afflict naïve set theory. Here I suggest that they are the very same paradoxes, because sets can be reduced to states of affairs. However, to obtain a consistent theoretical reduction we must restrict the usual axiom scheme of Comprehension for plural logic to ‘stratified’ formulas, to avoid viciously circular definitions. I prove that with this modification to the background plural logic, the theory of states of affairs is consistent; moreover, it yields the axioms of the familiar set theory NFU. (shrink)

What is exemplification? A proposition that attributes a property to an object is true if the object exemplifies the property. But according to the correspondence theory, a proposition is true if the corresponding fact exists. So if the correspondence theory is correct, an exemplification of a temporal property by an object is simply the concrete circumstance of the object’s having the property. But since not all properties are temporal, not all exemplifications are circumstances, and we need to recognise timeless as (...) well as temporal facts. This distinction allows us to solve the problem of converse relations, and to give an account of the logically complex facts which deduction allows us to know. (shrink)

Research into learners' ideas aboutscience suggests that school and collegestudents often hold alternative conceptionsabout `the atom'. This paper discusses whylearners acquire ideas about atoms which areincompatible with the modern scientificunderstanding. It is suggested that learners'alternative ideas derive – at least in part –from the way ideas about atoms are presented inthe school and college curriculum. Inparticular, it is argued that the atomicconcept met in science education is anincoherent hybrid of historical models, andthat this explains why learners commonlyattribute to atoms properties (...) (such as beingthe constituent particles of all substances, orof being indivisible and conserved inreactions) that more correctly belong to otherentities (such as molecules or sub-atomicparticles). Bachelard suggested that archaicscientific ideas act as `epistemologicalobstacles', and here it is argued thatanachronistic notions of the atom survive inthe chemistry curriculum. These conceptualfossils encourage learners to develop an`atomic ontology' (granting atoms `ontologicalpriority' in the molecular model of matter); tomake the `assumption of initial atomicity' whenconsidering chemical reactions; and to developan explanatory framework to rationalisechemical reactions which is based on thedesirability of full electron shells. Theseideas then act as impediments to thedevelopment of a modern chemical perspective onthe structure of matter, and an appreciation ofthe nature of chemical changes at the molecularlevel. (shrink)

The fact that humans cooperate with nonkin is something we take for granted, but this is an anomaly in the animal kingdom. Our species’ ability to behave prosocially may be based on human-unique psychological mechanisms. We argue here that these mechanisms include the ability to care about the welfare of others (other-regarding concerns), to “feel into” others (empathy), and to understand, adhere to, and enforce social norms (normativity). We consider how these motivational, emotional, and normative substrates of prosociality develop in (...) childhood and emerged in our evolutionary history. Moreover, we suggest that these three mechanisms all serve the critical function of aligning individuals with others: Empathy and other-regarding concerns align individuals with one another, and norms align individuals with their group. Such alignment allows us to engage in the kind of large-scale cooperation seen uniquely in humans. (shrink)

The views of myth advanced by Eliade, Jung, and Campbell are as flawed as they have been influential. Despite differences, all three concur in granting myth the status of a product of natural signification. The result is an obscurantist representation of myth, which in fact abets myth’s aim to represent itself as timeless, noncontingent, apolitical fact. Barthian analysis of myth exposes this aim by identifying its semiotic structure. This study applies that analysis to the myth of Pandora as an instance (...) of how myth insinuates itself into ordinary signs in order to pass as elementary and also elemental truth. (shrink)

Kant makes it clear in the Inaugural Dissertation that all the sense‐representations which form the material content of human knowledge are simply ‘modifications of inner sense’. Immortality would be, Kant suggests, the continuation of the unity of one's experience in a differently intuited world; ‘those transcendental objects, which in our present state appear as bodies, could be intuited in an entirely different manner’. Just as the early rationalist doctrine of the self is denied speculative validity, but admitted as a practical (...) postulate of morality; so the early rationalist doctrine of God is retained, but solely for practical use, without any cognitive function. Kant's contention that the ideal of God is a postulate for the employment of understanding in the investigation of nature is not usually granted much force in contemporary thought. Positively, the absolute demands of categorical morality require the postulates of freedom, immortality and God as a condition of their intelligibility. (shrink)

Hume’s Dialogues Concerning Natural Religion, Dialogues 1–11 discuss religion’s foundation in human reason. Dialogue 12, in which Philo. the relentless opponent of pro-theistic arguments, makes his “confession” that he embraces natural religion; namely, the view that the cause or causes of order in nature bear some remote analogy to human intelligence. Hume’s Natural History of Religion, although published earlier than the posthumous Dialogues, is, in effect, a second volume to them. It presents a complex naturalistic explanation of religion’s origin in (...) human nature, providing a sophisticated account of religion’s origin that is also a critique of religious belief. The core of this critique is an argument that theistic belief cannot be rendered so as to significantly differ from an atheism that grants that natural order has some cause or other. (shrink)

In his book, A Theory of Truces, Nir Eisikovits offers a perceptive and timely ethics of truces based on the claim that we need to reject the ‘false dichotomy between the ideas of war and peace’ underpinning much current thought about conflict and conflict resolution. In this article, I concur that truces and ‘truce thinking’ should be a focus of concern for any political theory wishing to address the realities of war. However, Eisikovits’s account, to be convincing, requires engagement with (...) a tradition of thought figuring only marginally in his reflections on truces, that is, just war theory. I argue this for three reasons. Without incorporation of the just war principles that should inform the decisions to enter conflict, to maintain conflict, and to cease conflict, any theory of truces will be, first, normatively inadequate, failing to provide us with requisite direction, and, second, open to the charge of permitting intolerable injustices, a charge Eisikovits wishes to avoid. Third, engagement with just war theory is important for arriving at a nuanced understanding of peacemaking, one which grants truces their place in our deliberations and spurns simplistic ‘war versus peace’ binaries whilst keeping more ambitious ideals of peace firmly in sight.

This article argues that corrupt practices such as bribery and embezzlement, which scholars have previously assumed to be evidence of the breakdown of the state, may reinforce the state's administrative hierarchies under certain conditions. Drawing on a cross-national analysis of 132 countries and a detailed examination of the informal institutions of official graft in Ukraine, the article finds that where graft is systematically tracked, monitored, and granted by state leaders as an informal payment in exchange for compliance, it provides both (...) an added incentive to obey leaders' directives and the potent sanction of criminal prosecution in the event of disobedience. Where graft is informally institutionalized in this way, it provides the basis for state organizations that are effective at collecting taxes, maintaining public order, and repressing political opposition but that may undermine the development of liberal politics.

Drawing from a four-year study of US science institutions that support biological control of arthropods, this article examines the decline in biological control institutional capacity in California within the context of both declining public interest science and declining agricultural research activism. After explaining how debates over the public interest character of biological control science have shaped institutions in California, we use scientometric methods to assess the present status and trends in biological control programs within both the University of California Land (...) Grant System and the California Department of Food and Agriculture. We present available data on the number of scientific positions and the types of positions to discuss the impact on the amount of public interest research on biological control in California. We use sociograms to depict how biological control science networks have been reconfigured over time. Our quantitative and qualitative analyses indicate that the following factors contributed to the decline of biological control science in California over the 45-year period analyzed: (1) the institutional reconfiguration of university research priorities; (2) the fraying networks within and increasing specialization of biological control science; (3) the transformation of the social organization of the life science work, including privatization; and (4) the abandonment of this thematic area by civil society activist groups. This broad array of forces suggests that biological control, as a public interest science, will require a deliberate intervention, based on advocacy of clear public interest criteria. (shrink)

Guala appears to take social preferences for granted in his discussion of reciprocity experiments. While he does not overtly claim that social preferences are only by-products that arise in testing environments, he does assert that whatever they are they have little value in the real world. Experiments on animals suggest that social preferences may be unique to humans, supporting the idea that they might play a prominent role in our world.

Many philosophical debates take for granted that there is such a thing as ‘the’ common-sense conception of the phenomenon of interest. Debates about the nature of perception tend to take for granted that there is a single, coherent common-sense conception of vision, consistent with Direct Realism. This conception is often accorded an epistemic default status. We draw on philosophical and psychological literature on naïve theories and belief fragmentation to motivate the hypothesis that untutored common sense encompasses conflicting Direct Realist and (...) Indirect Realist conceptions: there is no such thing as ‘the’ common-sense conception of vision that could enjoy epistemic default status. To examine this hypothesis, a survey administered an agreement rating task with verbal and pictorial stimuli to lay participants. We found many laypeople simultaneously hold conflicting Direct Realist and Indirect Realist beliefs about vision. Against common assumptions, Direct Realist beliefs are not clearly dominant, and consistent adherence to Direct Realism is not the norm, but the exception. These findings are consistent with recent accounts of belief fragmentation. They forcefully challenge common methodology in philosophical debates about the nature of perception and beyond. (shrink)

Reading Kevin Hart’s creative hermeneutic of the ‘basileic’ reduction in his latest book, Kingdoms of God, naturally leads me to consider another eminent linguistic phenomenologist who continually occupies my thoughts. Although I have been reading Hart now for about 25 years, I have been reading Paul Ricoeur for a decade longer than that, and it is his theory of poetic discourse that my mind keeps tenaciously associating with Hart’s perspectives on parable. Granted, Hart never mentions Ricoeur in Kingdoms of God—unless (...) my careful reading is not so careful and I missed it! In Trespass of the Sign, however, he does note Ricoeur’s significance as a hermeneutical philosopher, specifically his emphasis on the distinction between the hermeneutics of faith and the hermeneutics of suspicion. Also, in an article on John Caputo’s postsecular philosophy of ‘religion without religion,’ Hart makes a brief comment on Ricoeur’s apparent Hegelianism with reference to a general theory of revelation as nonreligious and nontheistic. Still, nowhere that I know of does he extensively address Ricoeur’s fascinating discourse theory regarding metaphor, mimesis, narrative, and parable. If great minds think alike, then Hart and Ricoeur are, indeed, great minds, for, truly, Ricoeur’s reflections on parables and the Kingdom offer an intriguing gloss on Hart’s parabolic ‘basileiology.’ Translating Hart into Ricoeur, therefore, is, in my mind, an easy and profitable exercise that may well enhance the provocative character of Hart’s basileic reduction. Such a translation is the central purpose of this essay. (shrink)

Charles Travis’s new collection on perception brings together eleven of his previously published essays on this topic, some of which are substantially revised, plus one new essay. The intentionally ambiguous subtitle hints at the author’s endorsement of Fregean anti-psychologism, though influences from Wittgenstein and Austin are equally apparent. The work centres around two major questions in the philosophy of mind and perception. First, Travis argues against the view that perceptual experience, as distinct from perceptual judgement or belief, is representational, and (...) so belongs to what Travis calls ‘the conceptual’. This is contrasted with the ‘non-conceptual’, or ‘historical’; that is, environmental particulars which lack the generality of representational thought. The second is what Travis calls ‘the fundamental question of perception’; namely, how can perceptual experience make the world bear (rationally) upon what we are to think and do? The answer, he argues, cannot be found in terms of relations between thoughts—a purely conceptual affair—but in the way that thought is itself grounded in the particularity of experience. For perceptual experience to bear rationally upon thought at all—or, in more familiar Fregean terms, to bring ‘objects’ under ‘concepts’—perception must first make environmental particulars available to cognition. Thus, Travis argues, experience cannot itself be ‘conceptual’, or representational, on pain of undermining the very thing that grants us a recognisable, and so thinkable, world at all. (shrink)

Throughout his career, Keith Hossack has made outstanding contributions to the theory of knowledge, metaphysics and the philosophy of mathematics. -/- This collection of previously unpublished papers begins with a focus on Hossack's conception of the nature of knowledge, his metaphysics of facts and his account of the relations between knowledge, agents and facts. Attention moves to Hossack's philosophy of mind and the nature of consciousness, before turning to the notion of necessity and its interaction with (...) a priori knowledge. Hossack's views on the nature of proof, logical truth, conditionals and generality are discussed in depth. In the final chapters, questions about the identity of mathematical objects and our knowledge of them take centre stage, together with questions about the necessity and generality of mathematical and logical truths.

Keith Hossack argues in his The Metaphysics of Knowledge(2007) that knowledge is a simple and metaphysically fundamental relation between a thinker and a fact: knowledge is uptake of fact. Facts are conceived as combinations of particulars and universals, distinct from true propositions. Hossacks's general argument is, roughly, that one can define central philosophical concepts (belief, content, justification, etc.) if one assumes that knowledge is primitive, but that knowledge cannot be defined in terms of such concepts. In this paper, (...) I will question Hossack's view of knowledge and his use of knowledge in the theory of content. To anticipate one of the main points: there is knowledge that cannot be uptake of a fact, because there is no fact to be taken up. The conclusion is that Hossack needs either to revise his theory of facts or his metaphysics of knowledge. Something has to give. (shrink)

In this impressive second edition of Theory of Knowledge, Keith Lehrer introduces students to the major traditional and contemporary accounts of knowing. Beginning with the traditional definition of knowledge as justified true belief, Lehrer explores the truth, belief, and justification conditions on the way to a thorough examination of foundation theories of knowledge,the work of Platinga, externalism and naturalized epistemologies, internalism and modern coherence theories, contextualism, and recent reliabilist and causal theories. Lehrer gives all views careful examination and concludes (...) that external factors must be matched by appropriate internal factors to yield knowledge. This match of internal and external factors follows from Lehrer’s new coherence theory of undefeated justification. In addition to doing justice to the living epistemological traditions, the text smoothly integrates several new lines that will interest scholars. Also, a feature of special interest is Lehrer’s concept of a justification game.This second edition of Theory of Knowledge is a thoroughly revised and updated version that contains several completely new chapters. Written by a well-known scholar and contributor to modern epistemology, this text is distinguished by clarity of structure, accessible writing, and an elegant mix of traditional material, contemporary ideas, and well-motivated innovation.

The eminent philosopher Keith Lehrer offers an original and distinctively personal view of central aspects of the human condition, such as reason, knowledge, wisdom, autonomy, love, consensus, and consciousness. He argues that what is uniquely human is our capacity for evaluating our own mental states (such as beliefs and desires), and suggests that we have a system for such evaluation which allows the resolution of personal and interpersonal conflict. The keystone in this system is self-trust, on which reason, knowledge, (...) and wisdom are grounded. (shrink)

Russell's Principle states that in order to think about an object I must know which thing it is, in the sense of being able to distinguish it from all other things. I show that, contra Strawson, Evans and Cassam, Russell's Principle cannot be applied to first-person thought so as to yield necessary conditions of self-consciousness.

It is widely accepted that there is a visual field, but the analogous notion of an auditory field is rejected by many philosophers on the grounds that the metaphysics or phenomenology of audition lack the necessary spatial or phenomenological structure. In this paper, I argue that many of the common objections to the existence of an auditory field are misguided and that, contrary to a tradition of philosophical scepticism about the spatiality of auditory experience, it is as richly spatial as (...) visual experience—and in some ways even more so. By carefully considering the spatiality and boundedness of audition, along with how sounds or their sources are experienced as occurring within the surrounding acoustic environment, we can gain a better understanding of (i) our auditory experience of space and (ii) the conditions for the existence of spatial sensory fields in general in a way that does not privilege vision over the other senses.
