Metaphysics
The word metaphysics was not coined by the philosopher who defined it, but by an editor two centuries after his death. Aristotle, the towering figure of ancient Greek thought, never used the term in his own writings. Instead, he referred to the study of being qua being, or the investigation of existence itself. It was Andronicus of Rhodes, an editor of Aristotle's collected works in the first century BCE, who organized the scattered treatises and titled the collection Metaphysics. The Greek term literally means 'after the physics,' indicating that these texts were to be studied after Aristotle's works on natural science. This historical accident shaped the discipline's identity for over two millennia, framing it as the inquiry that lies beyond the physical world. The term entered the English language in the mid 1500s through the Latin word metaphysica, cementing its place as the study of the most fundamental features of reality.
Universals and Particulars
The debate over whether the color red exists independently of red objects has divided philosophers for centuries. Particulars are individual entities like a specific apple or the Eiffel Tower, unique and non-repeatable. Universals are general features like the color red that can be instantiated by many different particulars at the same time. Realists argue that universals are real, mind-independent entities that exist in addition to particulars. According to Platonic realists, the universal red would continue to exist even if there were no red things. A more moderate form of realism, inspired by Aristotle, states that universals depend on particulars, meaning that they are only real if they are instantiated. Nominalists reject the idea that universals exist in either form, claiming the world is composed exclusively of particulars. Conceptualists offer an intermediate position, stating that universals exist, but only as concepts in the mind used to order experience by classifying entities. This ancient dispute continues to influence modern discussions about the nature of reality and the categories of being.
Time and Change
The flow of time is not a universal truth but a matter of philosophical interpretation. According to the A-series theory, the flow of time is real, meaning that events are categorized into the past, present, and future. The present continually moves forward in time and events that are in the present now will eventually change their status and lie in the past. From the perspective of the B-series theory, time is static, and events are ordered by the temporal relations earlier-than and later-than without any essential difference between past, present, and future. Eternalism holds that past, present, and future are equally real, whereas presentism asserts that only entities in the present exist. Material objects persist through time and change in the process, like a tree that grows or loses leaves. The main ways of conceptualizing persistence through time are endurantism and perdurantism. According to endurantism, material objects are three-dimensional entities that are wholly present at each moment. As they change, they gain or lose properties but otherwise remain the same. Perdurantists see material objects as four-dimensional entities that extend through time and are made up of different temporal parts. At each moment, only one part of the object is present, not the object as a whole.
Common questions
Who coined the term metaphysics and when was it first used?
Andronicus of Rhodes coined the term metaphysics in the first century BCE. He organized Aristotle's scattered treatises and titled the collection Metaphysics two centuries after Aristotle's death. The Greek term literally means after the physics, indicating that these texts were to be studied after Aristotle's works on natural science.
What is the difference between realists and nominalists regarding universals?
Realists argue that universals are real, mind-independent entities that exist in addition to particulars. Nominalists reject the idea that universals exist in either form, claiming the world is composed exclusively of particulars. Conceptualists offer an intermediate position, stating that universals exist, but only as concepts in the mind used to order experience by classifying entities.
How does the A-series theory of time differ from the B-series theory?
According to the A-series theory, the flow of time is real, meaning that events are categorized into the past, present, and future. From the perspective of the B-series theory, time is static, and events are ordered by the temporal relations earlier-than and later-than without any essential difference between past, present, and future. Eternalism holds that past, present, and future are equally real, whereas presentism asserts that only entities in the present exist.
What is the hard problem of consciousness in the mind-body problem?
A key aspect of the mind-body problem is the hard problem of consciousness or how to explain that physical systems like brains can produce phenomenal consciousness. According to Cartesian dualism, minds and bodies are distinct substances that causally interact with each other in various ways but can, at least in principle, exist on their own. Materialists state that all reality is at its core material and explain mind in terms of certain aspects of matter, such as brain states, behavioral dispositions, or functional roles.
When did the Upanishads appear and what did they examine?
In ancient India, starting in the 7th century BCE, the Upanishads were written as religious and philosophical texts that examine how ultimate reality constitutes the ground of all being. They further explore the nature of the self and how it can reach liberation by understanding ultimate reality. This period also saw the emergence of Buddhism in the 6th century BCE, which denies the existence of an independent self and understands the world as a cyclic process.
The relationship between the mind and the body remains one of the most contentious issues in philosophy. According to Cartesian dualism, minds and bodies are distinct substances. They causally interact with each other in various ways but can, at least in principle, exist on their own. This view is rejected by monists, who argue that reality is made up of only one kind. According to metaphysical idealism, everything is mental or dependent on the mind, including physical objects, which may be understood as ideas or perceptions of conscious minds. Materialists, by contrast, state that all reality is at its core material. Some deny that mind exists but the more common approach is to explain mind in terms of certain aspects of matter, such as brain states, behavioral dispositions, or functional roles. Neutral monists argue that reality is fundamentally neither material nor mental and suggest that matter and mind are both derivative phenomena. A key aspect of the mind-body problem is the hard problem of consciousness or how to explain that physical systems like brains can produce phenomenal consciousness.
Possibility and Necessity
The concept of possible worlds has revolutionized how philosophers understand modality. Borrowing a term from German philosopher Gottfried Wilhelm Leibniz's theodicy, many metaphysicians use the concept of possible worlds to analyze the meaning and ontological ramifications of modal statements. A possible world is a complete and consistent way the totality of things could have been. For example, the dinosaurs were wiped out in the actual world but there are possible worlds in which they are still alive. According to possible world semantics, a statement is possibly true if it is true in at least one possible world, whereas it is necessarily true if it is true in all possible worlds. Modal realists argue that possible worlds exist as concrete entities in the same sense as the actual world, with the main difference being that the actual world is the world we live in while other possible worlds are inhabited by counterparts. This view is controversial and various alternatives have been suggested, for example, that possible worlds only exist as abstract objects or are similar to stories told in works of fiction.
Causality and Determinism
The relation between cause and effect is the engine of the universe, yet its nature remains elusive. Causality is the relation between cause and effect whereby one entity produces or alters another entity. For instance, if a person bumps a glass and spills its contents then the bump is the cause and the spill is the effect. The regularity theory of causation, inspired by David Hume's philosophy, states that causation is nothing but a constant conjunction in which the mind apprehends that one phenomenon, like putting one's hand in a fire, is always followed by another phenomenon, like a feeling of pain. According to nomic regularity theories, regularities manifest as laws of nature studied by science. Counterfactual theories focus not on regularities but on how effects depend on their causes. They state that effects owe their existence to the cause and would not occur without them. According to primitivism, causation is a basic concept that cannot be analyzed in terms of non-causal concepts, such as regularities or dependence relations. One form of primitivism identifies causal powers inherent in entities as the underlying mechanism. Eliminativists reject the above theories by holding that there is no causation.
Critiques and Revivals
Metaphysics has faced persistent attacks questioning its very legitimacy as a field of inquiry. One criticism argues that metaphysical inquiry is impossible because humans lack the cognitive capacities needed to access the ultimate nature of reality. This line of thought leads to skepticism about the possibility of metaphysical knowledge. Empiricists often follow this idea, like Hume, who asserts that there is no good source of metaphysical knowledge since metaphysics lies outside the field of empirical knowledge and relies on dubious intuitions about the realm beyond sensory experience. Arguing that the mind actively structures experience, Kant criticizes traditional metaphysics for its attempt to gain insight into the mind-independent nature of reality. He asserts that knowledge is limited to the realm of possible experience, meaning that humans are not able to decide questions like whether the world has a beginning in time or is infinite. Another criticism holds that the problem lies not with human cognitive abilities but with metaphysical statements themselves, which some claim are neither true nor false but meaningless. According to logical positivists, for instance, the meaning of a statement is given by the procedure used to verify it, usually through the observations that would confirm it. Based on this controversial assumption, they argue that metaphysical statements are meaningless since they make no testable predictions about experience.
Global Traditions
The roots of metaphysics extend far beyond the Western tradition, with speculations about the nature and origin of the universe found in ancient India, China, and Greece. In ancient India, starting in the 7th century BCE, the Upanishads were written as religious and philosophical texts that examine how ultimate reality constitutes the ground of all being. They further explore the nature of the self and how it can reach liberation by understanding ultimate reality. This period also saw the emergence of Buddhism in the 6th century BCE, which denies the existence of an independent self and understands the world as a cyclic process. At about the same time in ancient China, the school of Taoism was formed and explored the natural order of the universe, known as Tao, and how it is characterized by the interplay of yin and yang as two correlated forces. In ancient Greece, metaphysics emerged in the 6th century BCE with the pre-Socratic philosophers, who gave rational explanations of the cosmos as a whole by examining the first principles from which everything arises. Building on their work, Plato formulated his theory of forms, which states that eternal forms or ideas possess the highest kind of reality while the material world is only an imperfect reflection of them.
