In philosophy, a quality is an attribute or a property characteristic of an object. [1] In contemporary philosophy the idea of qualities, and especially how to distinguish certain kinds of qualities from one another, remains controversial. [1]
Aristotle analyzed qualities in his logical work, the Categories. To him, qualities are hylomorphically–formal attributes, such as "white" or "grammatical". Categories of state, such as "shod" and "armed" are also non–essential qualities (katà symbebekós). [2] Aristotle observed: "one and the selfsame substance, while retaining its identity, is yet capable of admitting contrary qualities. The same individual person is at one time white, at another black, at one time warm, at another cold, at one time good, at another bad. This capacity is found nowhere else... it is the peculiar mark of substance that it should be capable of admitting contrary qualities; for it is by itself changing that it does so". [3] Aristotle described four types of qualitative opposites: correlatives,contraries,privatives and positives. [4]
John Locke presented a distinction between primary and secondary qualities in An Essay Concerning Human Understanding . For Locke, a quality is an idea of a sensation or a perception. Locke further asserts that qualities can be divided in two kinds: primary and secondary qualities. Primary qualities are intrinsic to an object—a thing or a person—whereas secondary qualities are dependent on the interpretation of the subjective mode and the context of appearance. [1] For example, a shadow is a secondary quality. It requires a certain lighting to be applied to an object. For another example, consider the mass of an object. Weight is a secondary quality since, as a measurement of gravitational force, it varies depending on the distance to, and mass of, very massive objects like the Earth, as described by Newton's law. It could be thought that mass is intrinsic to an object, and thus a primary quality. In the context of relativity, the idea of mass quantifying an amount of matter requires caution. The relativistic mass varies for variously traveling observers; then there is the idea of rest mass or invariant mass (the magnitude of the energy-momentum 4-vector [5] ), basically a system's relativistic mass in its own rest frame of reference. (Note, however, that Aristotle drew a distinction between qualification and quantification; a thing's quality can vary in degree). [6]
Philosophy and common sense tend to see qualities as related either to subjective feelings or to objective facts. The qualities of something depends on the criteria being applied to and, from a neutral point of view, do not determine its value (the philosophical value as well as economic value). Subjectively, something might be good because it is useful, because it is beautiful, or simply because it exists. Determining or finding qualities therefore involves understanding what is useful, what is beautiful and what exists. Commonly, quality can mean degree of excellence, as in, "a quality product" or "work of average quality". It can also refer to a property of something such as "the addictive quality of nicotine". [7] In his book, Zen and the Art of Motorcycle Maintenance , Robert M. Pirsig examines concepts of quality in classical and romantic, seeking a Metaphysics of Quality and a reconciliation of those views in terms of non-dualistic holism.
Quality (Latin: quality, characteristic, property, condition) has three meanings:
a) neutral: the sum of all properties of an object, system or process b) evaluates: the quality of all properties of an object, system or process c) evaluates: the individual values preceding the action and its results With regard to points a) and b), quality is the designation of a perceptible state of systems and their characteristics, which is defined in this state in a certain period of time based on certain properties of the system. Quality could describe a product such as wine and its chemical components and the resulting subjectively assessable taste, as well as the processes of ripening the grape, the production and distribution of the wine, or the process of managing the winery. In the meaning b) one speaks of quality wine or wine with predicate or of excellent management.
With reference to c), quality is the sum of the individual (value) attitudes (properties) of a target-oriented individual. Quality is differentiated by "having" or "being". The aim to which qualitative action is directed towards goals or effects also has fundamental effects on the creation of long-term growing cultural capital and thus on the existence of trust values in a cooperating, stable, and in particular democratic society. [8]
Aesthetics is the branch of philosophy concerned with the nature of beauty and the nature of taste and, in a broad sense, incorporates the philosophy of art. Aesthetics examines the philosophy of aesthetic value, which is determined by critical judgments of artistic taste; thus, the function of aesthetics is the "critical reflection on art, culture and nature".
In ontology, the theory of categories concerns itself with the categories of being: the highest genera or kinds of entities. 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?"
In philosophy, empiricism is an epistemological view which holds that true knowledge or justification comes only or primarily from sensory experience and empirical evidence. It is one of several competing views within epistemology, along with rationalism and skepticism. Empiricists argue that empiricism is a more reliable method of finding the truth than purely using logical reasoning, because humans have cognitive biases and limitations which lead to errors of judgement. Empiricism emphasizes the central role of empirical evidence in the formation of ideas, rather than innate ideas or traditions. Empiricists may argue that traditions arise due to relations of previous sensory experiences.
The philosophy of perception is concerned with the nature of perceptual experience and the status of perceptual data, in particular how they relate to beliefs about, or knowledge of, the world. Any explicit account of perception requires a commitment to one of a variety of ontological or metaphysical views. Philosophers distinguish internalist accounts, which assume that perceptions of objects, and knowledge or beliefs about them, are aspects of an individual's mind, and externalist accounts, which state that they constitute real aspects of the world external to the individual. The position of naïve realism—the 'everyday' impression of physical objects constituting what is perceived—is to some extent contradicted by the occurrence of perceptual illusions and hallucinations and the relativity of perceptual experience as well as certain insights in science. Realist conceptions include phenomenalism and direct and indirect realism. Anti-realist conceptions include idealism and skepticism. Recent philosophical work have expanded on the philosophical features of perception by going beyond the single paradigm of vision.
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.
Truth or verity is the property of being in accord with fact or reality. In everyday language, it is typically ascribed to things that aim to represent reality or otherwise correspond to it, such as beliefs, propositions, and declarative sentences.
In common usage and in philosophy, ideas are the results of thought. Also in philosophy, ideas can also be mental representational images of some object. Many philosophers have considered ideas to be a fundamental ontological category of being. The capacity to create and understand the meaning of ideas is considered to be an essential and defining feature of human beings.
Edward Jonathan Lowe, usually cited as E. J. Lowe but known personally as Jonathan Lowe, was a British philosopher and academic. He was Professor of Philosophy at Durham University. He defended non-Cartesian dualism.
Associationism is the idea that mental processes operate by the association of one mental state with its successor states. It holds that all mental processes are made up of discrete psychological elements and their combinations, which are believed to be made up of sensations or simple feelings. In philosophy, this idea is viewed as the outcome of empiricism and sensationism. The concept encompasses a psychological theory as well as comprehensive philosophical foundation and scientific methodology.
Subjective idealism, or empirical idealism or immaterialism, is a form of philosophical monism that holds that only minds and mental contents exist. It entails and is generally identified or associated with immaterialism, the doctrine that material things do not exist. Subjective idealism rejects dualism, neutral monism, and materialism; it is the contrary of eliminative materialism, the doctrine that all or some classes of mental phenomena do not exist, but are sheer illusions.
Natural philosophy or philosophy of nature is the philosophical study of physics, that is, nature and the physical universe while ignoring any supernatural influence. It was dominant before the development of modern science.
Essence has various meanings and uses for different thinkers and in different contexts. It is used in philosophy and theology as a designation for the property or set of properties or attributes that make an entity the entity it is or, expressed negatively, without which it would lose its identity. Essence is contrasted with accident, which is a property or attribute the entity has accidentally or contingently, but upon which its identity does not depend.
In the philosophy of perception and philosophy of mind, direct or naïve realism, as opposed to indirect or representational realism, are differing models that describe the nature of conscious experiences; out of the metaphysical question of whether the world we see around us is the real world itself or merely an internal perceptual copy of that world generated by our conscious experience.
Philosophical realism—usually not treated as a position of its own but as a stance towards other subject matters— is the view that a certain kind of thing has mind-independent existence, i.e. that it exists even in the absence of any mind perceiving it or that its existence is not just a mere appearance in the eye of the beholder. This includes a number of positions within epistemology and metaphysics which express that a given thing instead exists independently of knowledge, thought, or understanding. This can apply to items such as the physical world, the past and future, other minds, and the self, though may also apply less directly to things such as universals, mathematical truths, moral truths, and thought itself. However, realism may also include various positions which instead reject metaphysical treatments of reality altogether.
The Categories is a text from Aristotle's Organon that enumerates all the possible kinds of things that can be the subject or the predicate of a proposition. They are "perhaps the single most heavily discussed of all Aristotelian notions". The work is brief enough to be divided not into books, as is usual with Aristotle's works, but into fifteen chapters.
On Generation and Corruption, also known as On Coming to Be and Passing Away is a treatise by Aristotle. Like many of his texts, it is both scientific, part of Aristotle's biology, and philosophic. The philosophy is essentially empirical; as in all of Aristotle's works, the inferences made about the unexperienced and unobservable are based on observations and real experiences.
In philosophy, potentiality and actuality are a pair of closely connected principles which Aristotle used to analyze motion, causality, ethics, and physiology in his Physics, Metaphysics, Nicomachean Ethics, and De Anima.
Corpuscularianism, also known as corpuscularism, is a set of theories that explain natural transformations as a result of the interaction of particles. It differs from atomism in that corpuscles are usually endowed with a property of their own and are further divisible, while atoms are neither. Although often associated with the emergence of early modern mechanical philosophy, and especially with the names of Thomas Hobbes, René Descartes, Pierre Gassendi, Robert Boyle, Isaac Newton, and John Locke, corpuscularian theories can be found throughout the history of Western philosophy.
The primary–secondary quality distinction is a conceptual distinction in epistemology and metaphysics, concerning the nature of reality. It is most explicitly articulated by John Locke in his Essay concerning Human Understanding, but earlier thinkers such as Galileo and Descartes made similar distinctions.
Substantial form is a central philosophical concept in Aristotelianism and, afterwards, in Scholasticism. The form is the idea, existent or embodied in a being, that completes or actualizes the potentiality latent in the matter composing the being itself. For Aristotle, in fact, matter is the basis of all that exists; it comprises the potentiality of everything, but of itself is not actually anything. A determinate thing only comes into being when the potentiality in matter is converted into actuality; this is achieved by the substantial form. It is substantial because it is the principle by which a material kind of thing is recognised as such.
