As the foundation of our rationality, logic has traditionally been considered fixed, stable and constant. This conception of the discipline has been challenged recently by the plurality of logics and in this book, Pavel Arazim extends the debate to offer a new view of logic as dynamic and without a definite, specific shape. The Problem of Plurality of Logics examines the origins of our standard view of logic alongside Kant's theories, the holistic view, the issue of logic's pragmatic significance and Robert Brandom's logical expressivism. Arazim then draws on proof-theoretical approaches to present a convincing argument for a dynamic version of logical inferentialism, which opens space for a new freedom to modify our own logic. He explores the scope, possibilities and limits of this freedom in order to highlight the future paths logic could take, as a motivation for further research. Marking a departure from logical monism and also from the recent doctrine of logical pluralism in its various forms, this book addresses current debates concerning the expressive role of logic and contributes to a lively area of discussion in analytic philosophy.

Ethology, or how animals relate to their environments, is currently enjoying increased academic attention. A prominent figure in this scholarship is Gilles Deleuze and yet, the significance of his relational metaphysics to ethology has still not been scrutinised. Jason Cullen's book is the first text to analyse Deleuze's philosophical ethology and he prioritises the theorist's examination of how beings relate to each other. For Cullen, Deleuze's Cinema books are integral to this investigation and he highlights how they expose a key Deleuzian theme: that beings are fundamentally continuous with each other. In light of this continuity then, Cullen reveals that how beings understand each other shapes them and allows them to transform their shared worlds.
