Intuitionistic mereology
A Slow Impossible Mirror Picture
A new type of impossible picture is presented and described. The picture involves an object along with its reflection in a plane mirror, delivering two apparently irreconcilable views of the object itself when seen simultaneously in its flesh and in the mirror. Contrary to other, more familiar impossible pictures, its interpretation requires explicit reasoning about the represented reality. It is a slow impossible picture
Counterpart theories for everyone
David Lewis’s counterpart theory (CT) is often seen as involving a radical departure from the standard, Kripke-style semantics for modal logic (ML), suggesting that we are dealing with deeply divergent accounts of our modal talk. However, CT captures but one version of the relevant semantic intuition, and does so on the basis of metaphysical assumptions (all worlds are equally real, individuals are world-bound) that are ostensibly discretionary. …
Paraconsistency in classical logic
On Doing Ontology Without Metaphysics
According to a certain, familiar way of dividing up the business of philosophy, made popular by Quine, ontology is concerned with the question of what entities exist (a task that is often identified with that of drafting a “complete inventory” of the universe) whereas metaphysics seeks to explain, of those entities, what they are (i.e., to specify the “ultimate nature” of the items included in the inventory). For instance, a thesis to the effect …
The Extensionality of Parthood and Composition
I focus on three mereological principles: the extensionality of parthood (EP), the uniqueness of composition (UC), and the extensionality of composition (EC). These principles are not equivalent. Nevertheless they are closely related (and often equated), since they all reflect the basic nominalistic dictum ‘No difference without a difference maker'. All of them, individually or collectively, have been challenged on philosophical grounds. In the f…
A note on the transitivity of parthood
That parthood is a transitive relation is among the most basic principles of classical mereology. Alas, it is also very controversial. In a recent paper, Ingvar Johansson has put forward a novel diagnosis of the problem, along with a corresponding solution. The diagnosis is on the right track, I argue, but the solution is misleading. And once the pieces are properly put together, we end up with a reinforcement of the standard defense of transitiv…
Vagueness in geography
Some have argued that the vagueness exhibited by geographic names and descriptions such as ‘Albuquerque’, ‘the Outback’, or ‘Mount Everest ’ is ultimately ontological: these terms are vague because they refer to vague objects, objects with fuzzy boundaries. I take the opposite stand and hold the view that geographic vagueness is exclusively semantic, or conceptual at large. There is no such thing as a vague mountain. Rather, there are many things…
Parts and Places
Thinking about space is thinking about spatial things. The table is on the carpet; hence the carpet is under the table. The vase is in the box; hence the box is not in the vase. But what does it mean for an object to be somewhere? How are objects tied to the space they occupy? In this book Roberto Casati and Achille C. Varzi address some of the fundamental issues in the philosophy of spatial representation. Their starting point is an analysis of …
Fiction and Metaphysics
Fiat and Bona Fide Boundaries
There is a basic distinction, in the realm of spatial boundaries, between bona fide boundaries on the one hand, and fiat boundaries on the other. The former are just the physical boundaries of old. The latter are exemplified especially by boundaries induced through human demarcation, for example in the geographic domain. The classical problems connected with the notions of adjacency, contact, separation and division can be resolved in an intuitiv…

Deviant Logic, Fuzzy Logic
Initially proposed as rivals of classical logic, alternative logics have become increasingly important in areas such as computer science and arti ficial intelligence. Fuzzy logic, in particular, has motivated major technological developments in recent years. Susan Haack's Deviant Logic provided an extended examination of the philosophical consequences of alternative logics. In this volume, Haack includes the complete text of Deviant Logic, as wel…
Holes and Other Superficialities
Holes and Other Superficialities
This investigation on the borderlines of metaphysics, everyday geometry and the theory of perception seeks to answer two basic questions: Do holes really exist? If they do, what are they? Holes are among entities that down-to-earth philosophers would like to expel from their ontological inventory. Casati and Varzi argues in favour of holes' existence, examining their ontology of holes, their geometry, their part-whole relations, their identity, t…
Holes and Other Superficialities
Speaking of Events
In recent years the idea that an adequate semantics of ordinary language calls for some theory of events has sparked considerable debate among linguists and philosophers. Speaking of Events offers a vivid and up-to-date indication of this debate, with emphasis precisely on the interplay between linguistic applications and philosophical implications. Each chapter has been written expressly for this volume by leading authors in the field, including…
