In ontology, the theory of categories concerns itself with the categories of being: the highest genera or kinds of entities according to Amie Thomasson. To investigate the categories of being, or simply categories, is to determine the most fundamental and the broadest classes of entities. A distinction between such categories, in making the categories or applying them, is called an ontological distinction. Various systems of categories have been proposed, they often include categories for substances, properties, relations, states of affairs or events. A representative question within the theory of categories might articulate itself, for example, in a query like, "Are universals prior to particulars?"
Epiphenomenalism is a position on the mind–body problem which holds that subjective mental events are completely dependent for their existence on corresponding physical and biochemical events within the human body, yet themselves have no influence over physical events. The appearance that subjective mental states influence physical events is merely an illusion, consciousness being a by-product of physical states of the world. For instance, fear seems to make the heart beat faster, but according to epiphenomenalism the biochemical secretions of the brain and nervous system —not the experience of fear—is what raises the heartbeat. Because mental events are a kind of overflow that cannot cause anything physical, yet have non-physical properties, epiphenomenalism is viewed as a form of property dualism.
Metaphysics is the branch of philosophy that studies the fundamental nature of reality. This includes studies of the first principles of: being or existence, identity, change, consciousness, space and time, necessity, actuality, and possibility. It can also include questions about the existence of God, as well as relationships between foundational philosophical ideas such as between mind and matter, cause and effect, substance and attribute, or potentiality and actuality.
Monism attributes oneness or singleness to a concept, such as to existence. Various kinds of monism can be distinguished:
In metaphysics, ontology is the philosophical study of being. It investigates what types of entities exist, how they are grouped into categories, and how they are related to one another on the most fundamental level. Ontologists often try to determine what the categories or highest kinds are and how they form a system of categories that encompasses the classification of all entities. Commonly proposed categories include substances, properties, relations, states of affairs, and events. These categories are characterized by fundamental ontological concepts, including particularity and universality, abstractness and concreteness, or possibility and necessity. Of special interest is the concept of ontological dependence, which determines whether the entities of a category exist on the most fundamental level. Disagreements within ontology are often about whether entities belonging to a certain category exist and, if so, how they are related to other entities.
In philosophy, physicalism is the view that "everything is physical", that there is "nothing over and above" the physical, or that everything supervenes on the physical. Physicalism is a form of ontological monism—a "one substance" view of the nature of reality as opposed to a "two-substance" or "many-substance" (pluralism) view. Both the definition of "physical" and the meaning of physicalism have been debated.
Substance theory, or substance–attribute theory, is an ontological theory positing that objects are constituted each by a substance and properties borne by the substance but distinct from it. In this role, a substance can be referred to as a substratum or a thing-in-itself. Substances are particulars that are ontologically independent: they are able to exist all by themselves. Another defining feature often attributed to substances is their ability to undergo changes. Changes involve something existing before, during and after the change. They can be described in terms of a persisting substance gaining or losing properties. Attributes or properties, on the other hand, are entities that can be exemplified by substances. Properties characterize their bearers; they express what their bearer is like.
The distinction between subject and object is a basic idea of philosophy.
Hylomorphism is a philosophical doctrine developed by the Ancient Greek philosopher Aristotle, which conceives every physical entity or being (ousia) as a compound of matter (potency) and immaterial form (act), with the generic form as immanently real within the individual. The word is a 19th-century term formed from the Greek words ὕλη and μορφή. Hylomorphic theories of physical entities have been undergoing a revival in contemporary philosophy.
In the philosophy of mind, mind–body dualism denotes either the view that mental phenomena are non-physical, or that the mind and body are distinct and separable. Thus, it encompasses a set of views about the relationship between mind and matter, as well as between subject and object, and is contrasted with other positions, such as physicalism and enactivism, in the mind–body problem.
Gilbert Ryle was a British philosopher, principally known for his critique of Cartesian dualism, for which he coined the phrase "ghost in the machine." He was a representative of the generation of British ordinary language philosophers who shared Ludwig Wittgenstein's approach to philosophical problems.
The Concept of Mind is a 1949 book by philosopher Gilbert Ryle, in which the author argues that "mind" is "a philosophical illusion hailing chiefly from René Descartes and sustained by logical errors and 'category mistakes' which have become habitual."
The "ghost in the machine" is a term originally used to describe and critique the concept of the mind existing alongside and separate from the body. In more recent times, the term has several uses, including the concept that the intellectual part of the human mind is influenced by emotions; and within fiction, for an emergent consciousness residing in a computer.
In ontology and the philosophy of mind, a non-physical entity is an object that exists outside physical reality. The philosophical schools of idealism and dualism assert that such entities exist, while physicalism asserts that they do not. Positing the existence of non-physical entities leads to further questions concerning their inherent nature and their relation to physical entities.
Philosophy of mind is a branch of philosophy that deals with the nature of the mind and its relation to the body and the external world.
Quietism in philosophy sees the role of philosophy as broadly therapeutic or remedial. Quietist philosophers believe that philosophy has no positive thesis to contribute, but rather that its value is in defusing confusions in the linguistic and conceptual frameworks of other subjects, including non-quietist philosophy. For quietists, advancing knowledge or settling debates is not the job of philosophy, rather philosophy should liberate the mind by diagnosing confusing concepts.
The mind–body problem is a philosophical problem concerning the relationship between thought and consciousness in the human mind, and the body.
Cartesianism is the philosophical and scientific system of René Descartes and its subsequent development by other seventeenth century thinkers, most notably François Poullain de la Barre, Nicolas Malebranche and Baruch Spinoza. Descartes is often regarded as the first thinker to emphasize the use of reason to develop the natural sciences. For him, philosophy was a thinking system that embodied all knowledge.
The following outline is provided as an overview of and topical guide to metaphysics:
In the philosophy of mind, logical behaviorism is the thesis that mental concepts can be explained in terms of behavioral concepts.
