A Theory Of Objects

By developing object calculi in which objects are treated as primitives, the authors are able to explain both the semantics of objects and their typing rules, and also demonstrate how to develop all of the most important concepts of object-oriented programming languages: self, dynamic dispatch, classes, inheritance, protected and private methods, prototyping, subtyping, covariance and contravariance, and method specialization. An innovative and important approach to the subject for researchers and graduates.

This is a philosophical work that develops a general theory of ontological objects and object-relations. It does this by examining concepts as acquired dispositions, and then focuses on perhaps the most important of these: the concept of learning. This concept is important because everything that we know and do in the world is predicated on a prior act of learning. A concept can have many meanings and can be used in a number of different ways, and this creates difficulty when considering the nature of objects and the relationships between them. To enable this, David Scott answers a series of questions about concepts in general and the concept of learning in particular. Some of these questions are: What is learning? What different meanings can be given to the notion of learning? How does the concept of learning relate to other concepts, such as innatism, development and progression? The book offers a counter-argument to empiricist conceptions of learning, to the propagation of simple messages about learning, knowledge, curriculum and assessment, and to the denial that values are central to understanding how we live. It argues that values permeate everything: our descriptions of the world, the attempts we make at creating better futures and our relations with other people.

A haunting and moving collection of original narratives that reveals an expatriate's coming-of-age in Paris and the magic she finds in ordinary objects An awkward, curious girl growing up in a foreign country, Stephanie LaCava finds solace and security in strange yet beautiful objects. When her father's mysterious job transports her and her family to the quaint Parisian suburb of Le Vésinet, everything changes for the young American. Stephanie sets out to explore her new surroundings and to make friends at her unconventional international school, but her curiosity soon gives way to feelings of anxiety and a deep depression. In her darkest moments, Stephanie learns to filter the world through her peculiar lens, discovering the uncommon, uncelebrated beauty in what she finds. Encouraged by her father through trips to museums and scavenger hunts at antique shows, she traces an interconnected web of narratives of long-ago outsiders, and of objects historical and natural, that ultimately help her survive. A series of illustrated essays that unfolds in cinematic fashion, An Extraordinary Theory of Objects offers a universal lesson—to harness the power of creativity to cope with loneliness, sadness, and disappointment to find wonder in the uncertainty of the future.

What is reality, really? Are humans more special or important than the non-human objects we perceive? How does this change the way we understand the world? We humans tend to believe that things are only real in as much as we perceive them, an idea reinforced by modern philosophy, which privileges us as special, radically different in kind from all other objects. But as Graham Harman, one of the theory's leading exponents, shows, Object-Oriented Ontology rejects the idea of human specialness: the world, he states, is clearly not the world as manifest to humans. At the heart of this philosophy is the idea that objects - whether real, fictional, natural, artificial, human or non-human - are mutually autonomous. In this brilliant new introduction, Graham Harman lays out the history, ideas and impact of Object-Oriented Ontology, taking in everything from art and literature, politics and natural science along the way. Graham Harman is Distinguished Professor of Philosophy at SCI-Arc, Los Angeles. A key figure in the contemporary speculative realism movement in philosophy and for his development of the field of object-oriented ontology, he was named by Art Review magazine as one of the 100 most influential figures in international art.

Although the theory of object-oriented programming languages is far from complete, this book brings together the most important contributions to its development to date, focusing in particular on how advances in type systems and semantic models can contribute to new language designs.The fifteen chapters are divided into five parts: Objects and Subtypes, Type Inference, Coherence, Record Calculi, and Inheritance. The chapters are organized approximately in order of increasing complexity of the programming language constructs they consider - beginning with variations on Pascal- and Algol-like languages, developing the theory of illustrative record object models, and concluding with research directions for building a more comprehensive theory of object-oriented programming languages.Part I discusses the similarities and differences between "objects" and algebraic-style abstract data types, and the fundamental concept of a subtype. Parts II-IV are concerned with the "record model" of object-oriented languages. Specifically, these chapters discuss static and dynamic semantics of languages with simple object models that include a type or class hierarchy but do not explicitly provide what is often called dynamic binding. Part V considers extensions and modifications to record object models, moving closer to the full complexity of practical object-oriented languages.Carl A.

Describes a new, systematic process philosophy of science and technology focused on the agency and mobility of objects.

"Judaism and Christianity as condensed illustrations of how people across time struggle with the materiality of life and death. Speaking across many fields, including classics, history, anthropology, literary, gender, and queer studies, the book journeys through the ancient Mediterranean world by way of the myriad physical artifacts that punctuate the transnational history of early Christianity. By bringing a psychoanalytically inflected approach to bear upon her materialist studies of religious history, Kotrosits makes a contribution not only to our understanding of Judaism and early Christianity, but also our sense of how different disciplines construe historical knowledge, and how we as people and thinkers understand our own relation to our material and affective past"--

Category theory is a general mathematical theory of structures and of structures of structures. It occupied a central position in contemporary mathematics as well as computer science. This book describes the history of category theory whereby illuminating its symbiotic relationship to algebraic topology, homological algebra, algebraic geometry and mathematical logic and elaboratively develops the connections with the epistemological significance.
