In this monograph I explore the relationship between contemporary scientific metaphysics and the informational turn in philosophy and logic. Scientific metaphysics and the philosophy of information are two of the newest and most important subdisciplines in philosophy and the philosophy of science. Both are very young as philosophical disciplines go, and many of their theoretical commitments have a common theoretical and metaphysical basis. Both are heavily influenced by naturalism and the sciences, and each informs the other at a foundational level in questions of ontology, cognition, and natural knowledge. The rise of the philosophy of information marks what has been called the informational turn in philosophy. This intellectual, methodological, and theoretic turn involves taking the nature and existence of data and information to be foundational and fundamental in the world, with the result being that much of philosophy must be seriously revised and updated on an informational basis. Scientific metaphysics is a new movement within philosophy and the philosophy of science that seeks to draw philosophy even closer to science in terms of method, ontological commitments, and application. One of the chief indications that both scientific metaphysics and the informational turn jointly influence contemporary philosophy and metaphysics is the occurrence of a corresponding informational turn in logic, which is one of the core historical disciplines of philosophy. In this book, Dr Bruce Long investigates the relationship and interplay between scientific metaphysics and the philosophy of information, and proposes a new informational scientific metaphysics as a candidate for solving numerous outstanding ontological and theoretical problems in the philosophy of information, theories of semantic information, and informational logic.
