A cosmological argument, in natural theology, is an argument which claims that the existence of God can be inferred from facts concerning causation, explanation, change, motion, contingency, dependency, or finitude with respect to the universe or some totality of objects. A cosmological argument can also sometimes be referred to as an argument from universal causation, an argument from first cause, the causal argument, or prime mover argument. Whichever term is employed, there are two basic variants of the argument, each with subtle yet important distinctions: in esse (essentiality), and in fieri (becoming).
Metaphysics is the branch of philosophy that studies the fundamental nature of reality. This includes the first principles of being or existence, identity, change, space and time, cause and effect, necessity, actuality, and possibility.
Alvin Carl Plantinga is an American analytic philosopher who works primarily in the fields of philosophy of religion, epistemology, and logic.
Analytic philosophy is a branch of philosophy using analysis, popular in the Western world and particularly the Anglosphere, which began around the turn of the 20th century in the contemporary era in Germany, the United Kingdom, United States, Canada, Australia, New Zealand, and Scandinavia, and continues today. Analytic philosophy is often contrasted with continental philosophy, coined as a catch-all term for other methods, prominent in Europe.
Aristotelianism is a philosophical tradition inspired by the work of Aristotle, usually characterized by deductive logic and an analytic inductive method in the study of natural philosophy and metaphysics. It covers the treatment of the social sciences under a system of natural law. It answers why-questions by a scheme of four causes, including purpose or teleology, and emphasizes virtue ethics. Aristotle and his school wrote tractates on physics, biology, metaphysics, logic, ethics, aesthetics, poetry, theatre, music, rhetoric, psychology, linguistics, economics, politics, and government. Any school of thought that takes one of Aristotle's distinctive positions as its starting point can be considered "Aristotelian" in the widest sense. This means that different Aristotelian theories may not have much in common as far as their actual content is concerned besides their shared reference to Aristotle.
William Lane Craig is an American analytic philosopher, Christian apologist, author, and Wesleyan theologian who upholds the view of Molinism and neo-Apollinarianism. He is a professor of philosophy at Houston Christian University and at the Talbot School of Theology of Biola University. Craig has updated and defended the Kalam cosmological argument for the existence of God. He has also published work where he argues in favor of the historical plausibility of the resurrection of Jesus. His study of divine aseity and Platonism culminated with his book God Over All.
David Kellogg Lewis was an American philosopher who is widely regarded as one of the most important philosophers of the 20th century. Lewis taught briefly at UCLA and then at Princeton University from 1970 until his death. He is closely associated with Australia, whose philosophical community he visited almost annually for more than 30 years.
In philosophy, metaphysical necessity, sometimes called broad logical necessity, is one of many different kinds of necessity, which sits between logical necessity and nomological necessity, in the sense that logical necessity entails metaphysical necessity, but not vice versa, and metaphysical necessity entails physical necessity, but not vice versa. A proposition is said to be necessary if it could not have failed to be the case. Nomological necessity is necessity according to the laws of physics and logical necessity is necessity according to the laws of logic, while metaphysical necessities are necessary in the sense that the world could not possibly have been otherwise. What facts are metaphysically necessary, and on what basis we might view certain facts as metaphysically but not logically necessary are subjects of substantial discussion in contemporary philosophy.
A possible world is a complete and consistent way the world is or could have been. Possible worlds are widely used as a formal device in logic, philosophy, and linguistics in order to provide a semantics for intensional and modal logic. Their metaphysical status has been a subject of controversy in philosophy, with modal realists such as David Lewis arguing that they are literally existing alternate realities, and others such as Robert Stalnaker arguing that they are not.
The Kalam cosmological argument is a modern formulation of the cosmological argument for the existence of God. It is named after the Kalam, from which its key ideas originated. William Lane Craig was principally responsible for giving new life to the argument in the 20th century, due to his book The Kalām Cosmological Argument (1979), among other writings.
Hartry H. Field is an American philosopher. He is Silver Professor of Philosophy at New York University; he is a notable contributor to philosophy of science, philosophy of mathematics, epistemology, and philosophy of mind.
Modal realism is the view propounded by philosopher David Lewis that all possible worlds are real in the same way as is the actual world: they are "of a kind with this world of ours." It is based on four tenets: possible worlds exist, possible worlds are not different in kind from the actual world, possible worlds are irreducible entities, and the term actual in actual world is indexical, i.e. any subject can declare their world to be the actual one, much as they label the place they are "here" and the time they are "now".
Aristotle first used the term ethics to name a field of study developed by his predecessors Socrates and Plato which is devoted to the attempt to provide a rational response to the question of how humans should best live. Aristotle regarded ethics and politics as two related but separate fields of study, since ethics examines the good of the individual, while politics examines the good of the City-State, which he considered to be the best type of community.
Timothy Williamson is a British philosopher whose main research interests are in philosophical logic, philosophy of language, epistemology and metaphysics. He is the Wykeham Professor of Logic at the University of Oxford, and fellow of New College, Oxford.
The unmoved mover or prime mover is a concept advanced by Aristotle as a primary cause or "mover" of all the motion in the universe. As is implicit in the name, the unmoved mover moves other things, but is not itself moved by any prior action. In Book 12 of his Metaphysics, Aristotle describes the unmoved mover as being perfectly beautiful, indivisible, and contemplating only the perfect contemplation: self-contemplation. He equates this concept also with the active intellect. This Aristotelian concept had its roots in cosmological speculations of the earliest Greek pre-Socratic philosophers and became highly influential and widely drawn upon in medieval philosophy and theology. St. Thomas Aquinas, for example, elaborated on the unmoved mover in the Quinque viae.
Jonathan Peter Dancy is a British philosopher, who has written on ethics and epistemology. He is currently Professor of Philosophy at University of Texas at Austin and Research Professor at the University of Reading. He taught previously for many years at the University of Keele.
The following outline is provided as an overview of and topical guide to metaphysics:
Professor David Simon Oderberg is an Australian philosopher of metaphysics and ethics based in Britain since 1987. He is Professor of Philosophy at the University of Reading. He describes himself as a non-consequentialist or a traditionalist in his works. Broadly speaking, Oderberg places himself in opposition to Peter Singer and other utilitarian or consequentialist thinkers. He has published over thirty academic papers and has authored six books: The Metaphysics of Good and Evil, Opting Out: Conscience and Cooperation in a Pluralistic Society, Real Essentialism, Applied Ethics, Moral Theory, and The Metaphysics of Identity over Time. Professor Oderberg is an alumnus of the Universities of Melbourne, where he completed his first degrees, and Oxford where he gained his D.Phil.
An ontological argument is a philosophical argument, made from an ontological basis, that is advanced in support of the existence of God. Such arguments tend to refer to the state of being or existing. More specifically, ontological arguments are commonly conceived a priori in regard to the organization of the universe, whereby, if such organizational structure is true, God must exist.
Gideon Rosen is an American philosopher. He is a Stuart Professor of Philosophy at Princeton University, where he specializes in metaphysics, philosophy of mathematics, and ethics.
