Later, it was misinterpreted by Medieval commentators on the classical texts as that which is above or beyond the physical, and so over time metaphysics has effectively become the study of that which transcends physics. The problem of universals arises when people start to consider in what sense it is possible for a property to exist in more than one place at the same time (e.g. The study of ontology along with delving into the fundamentals of being, is also concerned with the classification of the entities of universe. Determinism is the philosophical proposition that every event, including human cognition, decision and action, is causally determined by an unbroken chain of prior occurrences. View this answer The three core branches of metaphysics are ontology, natural theology, and universal science. In his famous formulation "Cogito ergo sum" ("I think therefore I am"), René Descartes argued that consciousness is axiomatic, because you cannot logically deny your mind's existence at the same time as using your mind to do the denying. See the section on Realism for a further discussion of this. The identity of an entity composed of other entities can be explained by reference to the identity of the building blocks, and how they are interacting. Descartes and Leibniz believed that, without physical objects, "space" would be meaningless because space is the framework upon which we understand how physical objects are related to each other. Baruch Spinoza and Bertrand Russell both adopted, in different ways, a dual-aspect theory called Neutral Monism, which claims that existence consists of a single substance which in itself is neither mental nor physical, but is capable of mental and physical aspects or attributes. Greek philosopher Aristotle deemed metaphysics as wisdom and determined it to be the first philosophy. Arguably, metaphysics is the foundation of philosophy: Aristotle calls it "first philosophy" (or sometimes just "wisdom"), and says it is the subject that deals with "first causes and the principles of things". A house can be explained by reference to the wood, metal, and glass that are combined in that particular way to form the house; or it could be explained in terms of the atoms that form it (see the sections on Atomism and Reductionism). See the section on Philosophy of Religion for more details. The nature of the mind and its relation to the body has also exercised the best brains for millennia. It may be more useful to say that a metaphysical statement usually implies an idea about the world or the universe, which may seem reasonable but is ultimately not empirically verifiable, testable or provable. Metaphysics is an ancient branch of philosophy that provided a foundation for future philosophies. BRANCHES OF METAPHYSICS. ", "How can the incorporeal mind affect the physical body? Currently there are three main theories which deal with the problem of change: A traditional Realist position is that time and space have existence independent from the human mind. Metaphysicians are interested in the nature of objects and their properties, and the relationship between the two (see the sections on Realism and Nominalism). Causality is the law that states that each cause has a specific effect, and that this effect is dependent on the initial identities of the agents involved. The Philosophy of Mathematics overlaps with metaphysics in this area. Pantheists, such as Spinoza, believe that God and the universe are one and the same. A possible fact is one that is true in some possible world, even if not in the actual world. Realism, best exemplified by Plato and his Platonic Forms, teaches that universals really exist, independently and somehow prior to the world. © copyright 2003-2020 Study.com. This third edition is revised and updated and includes two new chapters on Time and Causation. Become a Study.com member to unlock this Early debates on the nature of matter centered on identifying a single underlying principle (Monism): water was claimed by Thales, air by Anaximenes, Apeiron (meaning "the undefined infinite") by Anaximander, and fire by Heraclitus. It asks questions like: Within Western Philosophy, Philosophy of Religion, and theology in general, reached its peak with Medieval Christian schools of thought like Scholasticism. ", "How does the world exist, and what is its origin or source of creation? It asks questions like: "What is the nature of reality? The dominant metaphysics in the 20th Century has therefore been various versions of Physicalism (or Materialism), a Monist solution which explains matter and mind as mere aspects of each other, or derivatives of a neutral substance. Aristotle's Law of Identity (or the Axiom of Identity) states that to exist, an existent (i.e. The world contains many individual things (objects or particulars), both physical and abstract, and what these things have in common with each other are called universals or properties. Ontology is the study (-ology) of being (onto-), and... Our experts can answer your tough homework and study questions. Moderate Realism, as espoused by Aristotle among others, tries to find some middle ground between Nominalism and Realism, and holds that there is no realm as such in which universals exist, but rather they are located in space and time wherever they happen to be manifest. Thus, there is at any instant only one physically possible future, and no random, spontaneous, mysterious or miraculous events ever occur. Metaphysics Metaphysics: A contemporary introduction is for students who have already done an introductory philosophy course. Some philosophers hold that there are abstract objects (such as numbers, mathematical objects and fictional entities) and universals (properties that can be possessed by multiple objects, such as "redness" or "squareness"), both of which are outside of space and time and/or are causally inert. We are intuitively aware of change occurring over time (e.g. Thus, according to Leibniz, if some object x is identical to some object y, then any property that x has, y will have as well, and vice versa (otherwise, by definition, they would not be identical). - Definition & History, What is Ontology? Other positions such as Formalism and Fictionalism do not attribute any existence to mathematical entities, and are anti-Realist. Also, to have an identity means to have a single identity: an object cannot have two identities at the same time or in the same respect. This idea of possible worlds was first introduced by Gottfried Leibniz, although others have dealt with it in much more detail since, notably the American analytic philosopher David Lewis (1941 - 2001) in his theory of Modal Realism. This question leads to the branch of metaphysics known as 'ontology'. It should be noted that Determinism does not necessarily mean that humanity or individual humans have no influence on the future (that is known as Fatalism), just that the level to which human beings have influence over their future is itself dependent on present and past.
