This book offers an in-depth and updated examination of the nature of haecceity—that primitive entity which explains why something is distinct from other things. The book begins by exploring different conceptions of haecceity throughout history. The discussion of various figures across history is important for getting clear on the nature of haecceity and its role in individuation. The next part of the book examines different views about the nature of haecceity. The author defends a view on which haecceities have objects that instantiate them as constituents. Following that, the book considers arguments for and against the existence of haecceities, the epistemology of haecceity, and the distinction between qualitative and non-qualitative properties. About Haecceity will appeal to scholars and advanced students working in metaphysics, philosophy of language, epistemology, logic, and history of philosophy.

Many contemporary philosophers are interested in the scotistic notion of haecceity or `thisness' because it is relevant to important problems concerning identity and individuation, reference, modality, and propositional attitudes. Haecceity is the only book-length work devoted to this topic. The author develops a novel defense of Platonism, arguing, first, that abstracta - nonqualitative haecceities - are needed to explain concreta's being diverse at a time; and second, that unexemplified haecceities are then required to accommodate the full range of cases in which there are possible worlds containing individuals not present in the actual world. In the cognitive area, an original epistemic argument is presented which implies that certain haecceities can be grasped by a person: his own, those of certain of his mental states, and those of various abstracta, but not those of external things. It is argued that in consequence there is a clear sense in which one is directly acquainted with the former entities, but not with external things.

Haecceities: Essentialism, Identity, and Abstraction is both an artistic and philosophical examination of the limits of Abstraction in art and of kinds of radical identity that are determined in the identification of those limits. Building on his work Subjects and Objects, Strayer shows how the fundamental conditions of making and apprehending works of art can be used, in concert with language, thought, and perception, as ‘material’ for producing the more Abstract and radical artworks possible. Certain limits of Abstraction and possibilities of radical identity are then identified that are critically and philosophically considered. They prove to be so extreme that the concepts artwork, abstraction, identity, and object in art, philosophy, and philosophy of art, have to be reconsidered.

This book offers a historical explanation of important philosophical problems in logic and mathematics, which have been neglected by the official history of modern logic. It offers extensive information on Gottlob Frege’s logic, discussing which aspects of his logic can be considered truly innovative in its revolution against the Aristotelian logic. It presents the work of Hilbert and his associates and followers with the aim of understanding the revolutionary change in the axiomatic method. Moreover, it offers useful tools to understand Tarski’s and Gödel’s work, explaining why the problems they discussed are still unsolved. Finally, the book reports on some of the most influential positions in contemporary philosophy of mathematics, i.e., Maddy’s mathematical naturalism and Shapiro’s mathematical structuralism. Last but not least, the book introduces Biancani’s Aristotelian philosophy of mathematics as this is considered important to understand current philosophical issue in the applications of mathematics. One of the main purposes of the book is to stimulate readers to reconsider the Aristotelian position, which disappeared almost completely from the scene in logic and mathematics in the early twentieth century.
