John Locke is the greatest English philosopher. _An Essay Concerning Human Understanding_, one of the most influential books in the history of thought, is his greatest work. In this study the historical meaning and philosophical significance of Locke's _Essay_ are investigated more comprehensively than ever before. _Locke_ was originally published in two volumes, _Epistemology_ and _Ontology_. This paperback edition has within its covers the full text of both volumes.

What is knowledge? What, if anything, can we know? Michael Ayers initiates a fresh approach to these questions by recovering the insight in the distinction between 'knowledge' and 'belief' that was common philosophical currency for two millennia after Plato. He argues that knowledge comes only with direct cognitive contact with reality or truth.

Consideration of the counting and reidentification of particulars leads naturally enough to the orthodox doctrine that, “on pain of indefiniteness,” an identity statement in some way involves or presupposes a general term or “covering concept”: i.e., that the principium individuationis or criterion of identity implied depends upon the kind of thing in question. Thus it is said that an auditor understands the question whether A is the same as B only in so far as he knows, however informally or implicitly, (...) the answer to the supplementary question, “The same what?”.

Philosophers debate whether all, some or none of the represcntational content of our sensory experience is conccptual, but the technical term "concept" has different uses. It is commonly linked more or less closely with the notions of judgdment and reasoning, but that leaves open the possibility that these terms share a systematic ambiguity or indeterminacy. Donald Davidson, however, holds an unequivocal and consistent, if paradoxical view that there are strictly speaking no psychological states with representational or intentional content except the (...) propositional attitudes of language users, since thc source or fundamental bearer of intentionality is the employed sentence. Accordingly he claims that what has content in ordinary sense experience is not sensation, but propositional belief caused, but not justified, by sensation. John McDowell, sharing some ofDavidson's premises,holds a less paradoxical, but (l will argue) equivocal and incoherent view that post-infantile human sensory expcrience must have content in so far as it is what grounds perceptual belief but that this content is itself conceptual or propositional, dependent on language and culture. Reasons are givcn in the present article for rejecting both views, and their common premises. It is argued that perceptual or sensory states have intentional content which is no more conceptual or propositional than the world is. Recognition that perceptual content and conceptual content are, in a certain unsurprising way incommensurable allows for a more realistic understanding of the relationship between Language and the world as we experience it.

The Cambridge History of 17th Century Philosophy offers a uniquely comprehensive and authoritative overview of early-modern philosophy written by an international team of specialists. As with previous Cambridge histories of philosophy the subject is treated by topic and theme, and since history does not come packaged in neat bundles, the subject is also treated with great temporal flexibility, incorporating frequent reference to medieval and Renaissance ideas. The basic structure of the volumes corresponds to the way an educated seventeenth - century (...) European might have organized the domain of philosophy. Thus, the history of science, religious doctrine, and politics feature very prominently. The narrative that unfolds begins with an intellectual world dominated by a synthesis of Aristotelianism and scholastic philosophy, but by the end of the period the mechanistic or "corpuscularian" philosophy has emerged and exerted its full impact on traditional metaphysics, ethics, theology, logic, and epistemology.

A scholastic-Cartesian schema faithfully maps ordinary, effective ways of dealing with intentionality; yet its apparent incoherence provokes philosophers into opting for one of two stances, 'Cartesian' or 'direct realist', seemingly incompatible, yet each seem in accord with ordinary thought. A wide range of canonical and current theories, realist, idealist and hybrid, essentially involve one option or the other. We should instead consider why the language of intentionality, with its apparent anomalies, works so well. Released from the obligation to opt for (...) one stance over the other, we can identify a robust realism different in kind from anything currently on offer. (shrink)

Perhaps everyone who can think has the concept of possibility, but no one understands it. The metaphysical theory of Determinism is a symptom of this lack of understanding, and the inconclusiveness of its opponents’ arguments indicates that the lack is universal. In this book, first published in 1968, the author shows that there are a number of different kinds on non-logical possibility, subtly interrelated, each requiring separate explanation. An original contribution to the subject, it is essential reading for all students (...) of philosophy. (shrink)

The thesis of this paper concerns the fundamental role of "ordinary objects" with respect to the structure of natural language. It ascribes their role as basic objects of reference to their being both natural and "given" individuals. Section 1 will summarize that idea. Further argument will be offered in Section 2. An objection appealing to physical theory will be answered in Section 3. Sections 4, 5, and 6 consider the implications of the thesis for current theories of the identity of (...) "ordinary objects" over time. Section 4 deals with some traditional, paradoxical, but still influen tial arguments. Section 5 focuses on four-dimensionalism and the ontology of possible worlds. Section 6 examines the theory of David Wiggins, who recognizes that biological individuals, at least, are both natural and given, but who retains a form of conceptualism. Some remarks are made through out about the wider philosophical motivations of different approaches to the topic of identity, and about the nature of philosophical "analysis.". (shrink)

Rationalism, Platonism and God comprises three main papers on Descartes, Spinoza and Leibniz, with extensive responses. It provides a significant contribution to the exploration of the common ground of the great early-modern Rationalist theories, and an examination of the ways in which the mainstream Platonic tradition permeates these theories. -/- John Cottingham identifies characteristically Platonic themes in Descartes's cosmology and metaphysics, finding them associated with two distinct, even opposed attitudes to nature and the human condition, one ancient and 'contemplative', the (...) other modern and 'controlling'. He finds the same tension in Descartes's moral theory, and believes that it remains unresolved in present-day ethics. -/- Was Spinoza a Neoplatonist theist, critical Cartesian, or naturalistic materialist? Michael Ayers argues that he was all of these. Analysis of his system reveals how Spinoza employed Neoplatonist monism against Descartes's Platonist pluralism. Yet the terminology - like the physics - is Cartesian. And within this Platonic-Cartesian shell Spinoza developed a rigorously naturalistic metaphysics and even, Ayers claims, an effectually empiricist epistemology. -/- Robert Merrihew Adams focuses on the Rationalists' arguments for the Platonist, anti-Empiricist principle of 'the priority of the perfect', i.e. the principle that finite attributes are to be understood through corresponding perfections of God, rather than the reverse. He finds the given arguments unsatisfactory but stimulating, and offers a development of one of Leibniz's for consideration. -/- These papers receive informed and constructive criticism and development at the hands of, respectively, Douglas Hedley, Sarah Hutton and Maria Rosa Antognazza.

‘Empiricism’ has become for many a dirty word, and many writers have in mind the kind of neo-Humean Positivism that is the target of Wittgenstein’s Private Language Argument, Quine’s ‘Two Dogmas of Empiricism’, or Merleau-Ponty’s Phénoménologie de la perception. But examination of the Empiricist tradition before Hume uncovers views that do not involve anything like the much-abused “Myth of the Given” or twentieth-century sensedatum theory. This paper identifiesthe particular line of seventeenth-century thought that eventually gave rise to sense-datum theory, and (...) discusses other notions of experience that avoid it. The aim of this history lesson is to point to the possibility of an essentially empiricist approach today, an approach that avoids the neo-idealism or conceptualism of popular modern alternatives to sensedatum theory.

Minds, Ideas and Objects is a collection of conference papers on the topic of seventeenth- and eighteenth-century theories of ideas or “sensory experience, thought, knowledge and their objects.” At least half the twenty-three papers are by well-known historians of philosophy who seldom disappoint, and there is some equally thought-provoking work among the rest. Some papers say little that is surprising, and some, including good ones, fail to convince, but few are weak. It is perhaps to be expected that coverage of (...) the period is uneven, but chance has played some odd tricks, giving us one paper each on Leibniz and Hume and none on Spinoza, whereas Berkeley excites the attention of six contributors, one more even than Kant. Most philosophers discussed are narrowly canonical, with just a page on Cudworth and only four even on Reid, but there are a couple of welcome articles on the vastly rewarding, until recently seldom studied Arnauld-Malebranche debate. Günter Zöller’s “The Austrian Way of Ideas,” summarizing the views on intentionality of Brentano and his pupils, Twardowski, Meinong, and Husserl, reminds us of the close continuities between early-modern and twentieth-century concerns.

No doubt most philosophers who spend time on the history of philosophy are familiar with that question asked to embarrass (and liable to be asked by scientists in particular) why the history of the subject should be thought a significant part of the subject itself. Either there is progress in philosophy, it is said, or there is not. If there is progress, why the laborious backward glances? How can the past be so important? Why aren’t philosophers like psychologists, given perhaps (...) a short historical orientation before being brought up to the nitty-gritty of the present? If, on the other hand, there is no progress, if we might as well be discussing Locke as Quine, doesn’t that imply that philosophy consists in a set of questions for which there is no way of establishing even that some answers are better than others? Wouldn’t it be more profitable to pursue questions to which at least provisional answers can be established, approximating to the truth? Wouldn’t it be better to be a scientist? (shrink)
