Russell wrote in 1918 in The Philosophy of Logical Atomism: When I speak of a fact ... I mean the kind of thing that makes a proposition true or false. If I say 'It is raining', what I say is true in a certain condition of weather and is false in other conditions of the weather. The condition of weather that makes my state­ment true (or false as the case may be), is what I should call a 'fact'. If I say, 'Socrates is dead', my statement will be true owing to a certain physiological occurrence which happened in Athens long ago. This classic statement of Russell's version of the correspondence theory of truth is defective on one point only: Russell was unwise to use the word 'fact'. Objects which perform the semantic role Russell accords to facts I shall call simply truth-makers.

Grenon and Smith (2004) propose a framework for the ontology of things in space and time involving and invoking the distinction between continuants and occurrents, which has become a key element of Basic Formal Ontology (BFO). The terminology of SNAP (from “snapshot:” state of a continuant at a time) and SPAN (how an occurrent develops over an interval or timespan) occurs in that paper’s title. While any commonsense ontology will have a place for both continuants and occurrents, there is much room for philosophical debate on whether one of them is more basic than the other, or can be reduced to the other, or whether they are equally fundamental, or whether they are two different perspectives on the same reality. Grenon and Smith opt for the last of these. They call the accounts of continuants (SNAP) and occurrents (SPAN) both “ontologies.” They do not have a single ontology of all that is in space and time. This dialog throws a few of the common arguments around a bit and comes to no sure conclusion. But one of the characters bears a faint resemblance to a certain Buffalonian philosopher.

Summary The introduction of computers into the process of musical composition markedly disturbs the relationships which normally obtain between composer, work, performances, and sound complexes. This shift gives rise to a number of philosophical problems with far-reaching consequences, which this paper discusses. The conclusion is that the use of computers in composition exposes a crisis facing the notion of a work of music, whose outcome cannot yet be foreseen. In its subject matter, the paper takes up issues raised by Roman Ingarden's phenomenological ontology of art works. The use of example and counterexample to probe the boundaries of the notion of a work of music on the other hand owes more to Husserl's method of eidetic variation.

Many mereological propositions are true contingently, so we are entitled to ask why they are true. One frequently given type of answer to such questions evokes truth-makers, that is, entities in virtue of whose existence the propositions in question are true. However, even without endorsing the extreme view that all contingent propositions have truth-makers, it turns out to be puzzlingly hard to provide intuitively convincing candidate truth-makers for even a core class of basic mereological propositions. Part of the problem is that the relation of part to whole is ontologically intimate in a way reminiscent of identity. Such intimacy bespeaks a formal or internal relation, which typically requires no truth-makers beyond its terms. But truth-makers are held to necessitate their truths, so whence the contingency when A is part of B but need not be, or B need not have A as part? This paper addresses and attempts to disentangle the conundrum.

Alexius Meinong is one of the foremost, most independent-minded, most distinctive, most misunderstood and most unjustly maligned of all philosophers. He was pilloried by his own teacher Brentano and his one-time admirer Bertrand Russell as what Gilbert Ryle called “perhaps the supreme entity-multiplier in the history of philosophy.” It is often enough to employ the adjective ‘Meinongian’ to cast a philosopher’s views into the outer darkness. But as supreme commentator J. N. Findlay observes, Meinong was a painstakingly careful and methodical thinker, who inched his way forward to his radical ontological views. Meinong maintained a running interest in ethics and value theory, and the subjective experiences of feeling and desire that correlate to these spheres, from his 1894 Psychological-ethical investigations in value theory to his late works Emotional presentation and the posthumous On the foundation of general value theory. In the process he graduated from value subjectivism to value objectivism. In this paper we will survey Meinong’s mature theory of intentionality and its objects, with particular attention to the otherwise neglected dignitatives and desideratives.

The metaphysics of relations is still in its infancy. We use the idea of truthmaking to gain purchase on this metaphysics. Assuming a modest supervenience conception of truthmaking, where true relational predications require multiply dependent truthmakers, these are indispensable relations. Though some such relations are required, none are needed for internal relatedness, nor for several other kinds of relational predication. Discerning the metaphysically basic kinds of relations is fraught with uncertainties, but must be tackled if progress is to be made.

Philosophen, insbesondere Wissenschaftstheoretiker, wurden oft so sehr von der Physik geblendet, dass sie die Bedeutung der Biologie für die Philosophie unterschätzt haben. Es wird beschrieben, wie Biologen in der Taxonomie mit der Klassifikation umgehen, wie verschieden ihre Vorgangsweise von der traditionellen Definitions-und Klassifikationstheorie ist, und wie sie die klare Fregesche Trennung zwischen Extension und Intension durcheinander bringt. Dadurch können Sprachphilosophen von Biologen über die Sprache etwas lernen. Auf der anderen Seite können sprachphilosophische Unterscheidungen etwa in der Theorie der pluralen Referenz, einen Beitrag leisten zur Entschärfung der biologischen Kontroverse darüber, ob Spezies und andere Taxa Klassen oder Individuen sind.

The Routledge Companion to Metaphysics is an outstanding, comprehensive and accessible guide to the major themes, thinkers, and issues in metaphysics. The Companion features over fifty specially commissioned chapters from international scholars which are organized into three clear parts: History of Metaphysics Ontology Metaphysics and Science. Each section features an introduction which places the range of essays in context, while an extensive glossary allows easy reference to key terms and definitions. The Routledge Companion to Metaphysics is essential reading for students of philosophy and anyone interested in surveying the central topics and problems in metaphysics from causation to vagueness and from Plato and Aristotle to the present-day
