Aristotle observes that substances have no contraries. Consider one possible role that the contrary of a substance might play, were it to exist. Just as objects serve as guarantors of the instantiation of properties, contraries of objects could serve as guarantors of the non‐instantiation of properties. By first considering a reframing of deontic logic that takes ‘being permitted’ rather than ‘being forbidden’ as the default state, I develop logical tools that allow the construction of extremal models in which everything is permitted and nothing is forbidden. Transferred to quantified logic, these same tools give us a conception of antiobjects which block property instantiation. The resulting picture of antiobjects is then used as a test case to examine questions about the role of symmetry considerations in philosophical methodology.

It is a fundamental feature of language that words refer to things. Much attention has been devoted to the nature of reference, both in philosophy and in linguistics. Puzzles of Reference is the first book to give a comprehensive accessible survey of the fascinating work on this topic from the 1970s to the present day. Written by two eminent philosophers of language, Puzzles of Reference offers an up-to-date introduction to reference in philosophy and linguistics, summarizing ideas such as Kripke's revolutionary theory and presenting the various challenges in a clear and accessible manner. As the text does not assume prior training in philosophy or linguistics, it is ideal for use as part of a philosophy of language course for philosophy students or for linguistics students. Puzzles of Reference belongs to the series Contemporary Introductions to Philosophy of Language, in which each book provides an introduction to an important area of the philosophy of language, suitable for students at any level.

Context and Communication offers an introduction to a central theme in the study of language: the various ways in which what we say depends on the context of speech and thought. The period since 1970 has produced a vast literature on this topic, both by philosophers and by linguists. This book explores key data, questions, concepts, and theories of context sensitivity. It is written to be accessible to someone with no prior knowledge of the material or, indeed, any prior knowledge of philosophy, and is ideal for use as part of a philosophy of language course by students of philosophy or linguistics.
