The book opens with an outline of the general theory of metaphysics, which creates the underlying framework for all subsequent chapters. Having identified four options for subject-object relations, the book then applies these to examinations of linguistics, hermeneutics, determinism, the ethics of economics as cyberethics and cybereconomics, and the social sciences. The books also dissects "lifeworld" into "object" and "methodological" or "approach" lifeworld and shows through semantics that human factors engineering as probably identified with metaphysics as theoretical and applied. Other topics for intellectual discourse include public versus private property, God, empirical and rational knowledge, and technology's relation to science and art.
Written in recognition of ethics and metaphysics as fundamental components of philosophy and the quest for wisdom, Unified Philosophy is a thought-provoking text for students of theology, ethics, and engineering. It shows how human factors engineering integrates with theoretical and applied metaphysics, and redefines civil engineering as the framework for all other engineering except military engineering. With its focus on philosophy as an integral part of liberal arts and sciences, it is also an excellent supplement for courses in economics, anthropology, and the arts.
