Semantic theory of truth A theory of truth in the philosophy of language A semantic theory of truth is a theory of truth in the philosophy of language which holds that truth is a property of sentences.[1] The semantic conception of truth, which is related in different ways to both the correspondence and deflationary conceptions, is due to work by Polish logician Alfred Tarski. Tarski's theory of truth [edit] To formulate linguistic theories[2] without semantic paradoxes such as the liar paradox, it is generally necessary to distinguish the language that one is talking about (the object language) from the language that one is using to do the talking (the metalanguage). Tarski's material adequacy condition, also known as Convention T, holds that any viable theory of truth must entail, for every sentence "P", a sentence of the following form (known as "form (T)"): (1) "P" is true if, and only if, P. For example, (2) 'snow is white' is true if and only if snow is white. Kripke's theory of truth
Philosophy of mind A phrenological mapping[1] of the brain – phrenology was among the first attempts to correlate mental functions with specific parts of the brain Philosophy of mind is a branch of philosophy that studies the nature of the mind, mental events, mental functions, mental properties, consciousness, and their relationship to the physical body, particularly the brain. The mind–body problem, i.e. the relationship of the mind to the body, is commonly seen as one key issue in philosophy of mind, although there are other issues concerning the nature of the mind that do not involve its relation to the physical body, such as how consciousness is possible and the nature of particular mental states.[2][3][4] Mind–body problem[edit] Our perceptual experiences depend on stimuli that arrive at our various sensory organs from the external world, and these stimuli cause changes in our mental states, ultimately causing us to feel a sensation, which may be pleasant or unpleasant. Arguments for dualism[edit]
Recursive definition Defining elements of a set in terms of other elements in the set The recursion theorem states that such a definition indeed defines a function that is unique. The proof uses mathematical induction.[1] An inductive definition of a set describes the elements in a set in terms of other elements in the set. of natural numbers is: 0 is in If an element n is in then n + 1 is in is the smallest set satisfying (1) and (2). There are many sets that satisfy (1) and (2) – for example, the set {0, 1, 1.649, 2, 2.649, 3, 3.649, …} satisfies the definition. Properties of recursively defined functions and sets can often be proved by an induction principle that follows the recursive definition. Form of recursive definitions [edit] Most recursive definitions have two foundations: a base case (basis) and an inductive clause. (i.e., inductive clause). Principle of recursive definition Let A be a set and let a0 be an element of A. such that Examples of recursive definitions Elementary functions ?
Axiology History[edit] Between the 5th and 6th century B.C., it was important in Greece to be knowledgeable if you were to be successful. Philosophers began to recognize that differences existed between the laws and morality of society. Socrates held the belief that knowledge had a vital connection to virtue, making morality and democracy closely intertwined. Socrates' student, Plato furthered the belief by establishing virtues which should be followed by all. With the fall of the government, values became individual, causing skeptic schools of thought to flourish, ultimately shaping a pagan philosophy that is thought to have influenced and shaped Christianity. Axiological Issues in Communication Studies[edit] Communication theorists seek to contribute to mutual intelligence about the anatomy and operation of human communication. Those who take a conventional scientific approach believe that research must be free of values in order to be valid. See also[edit] References[edit] Further reading[edit]

Epistemology Philosophical study of knowledge The school of skepticism questions the human ability to attain knowledge while fallibilism says that knowledge is never certain. Empiricists hold that all knowledge comes from sense experience, whereas rationalists believe that some knowledge does not depend on it. Separate branches of epistemology focus on knowledge in specific fields, like scientific, mathematical, moral, and religious knowledge. Early reflections on the nature, sources, and scope of knowledge are found in ancient Greek, Indian, and Chinese philosophy. Epistemology explores how people should acquire beliefs. The word epistemology comes from the ancient Greek terms ἐπιστήμη (episteme, meaning knowledge or understanding) and λόγος (logos, meaning study of or reason), literally, the study of knowledge. Knowledge is an awareness, familiarity, understanding, or skill. Knowledge contrasts with ignorance, often simply defined as the absence of knowledge. . Major schools of thought [edit]
Truth condition From Wikipedia, the free encyclopedia Condition required for a semantic statement to be true Notes and references [edit] Iten, C. (2005). Ontology Philosophical study of being Ontologists disagree about which entities exist on the most basic level. Platonic realism asserts that universals have objective existence. The origins of ontology lie in the ancient period with speculations about the nature of being and the source of the universe, including ancient Indian, Chinese, and Greek philosophy. Ontology is the study of being. The word ontology has its roots in the ancient Greek terms ὄντως (ontos, meaning being) and λογία (logia, meaning study of), literally, the study of being. The scope of ontology covers diverse entities, including everyday objects, living beings, celestial bodies, ideas, numbers, and fictional creatures. Being, or existence, is the main topic of ontology. The relation between being and non-being is a frequent topic in ontology.

Linguistic description Work of objectively describing a particular language All academic research in linguistics is descriptive; like all other scientific disciplines, it seeks to describe reality, without the bias of preconceived ideas about how it ought to be.[2][3][4][5] Modern descriptive linguistics is based on a structural approach to language, as exemplified in the work of Leonard Bloomfield and others.[6] This type of linguistics utilizes different methods in order to describe a language such as basic data collection, and different types of elicitation methods.[7] Descriptive versus prescriptive linguistics[edit] Linguistic description is often contrasted with linguistic prescription,[8] which is found especially in education and in publishing.[9][10] History of the discipline[edit] Even though more and more languages were discovered, the full diversity of language was not yet fully recognized. Methods[edit] The first critical step of language description is to collect data. Challenges[edit] See also[edit]
Reality Not to be confused with Realty. Philosophers, mathematicians, and other ancient and modern thinkers, such as Aristotle, Plato, Frege, Wittgenstein, and Russell, have made a distinction between thought corresponding to reality, coherent abstractions (thoughts of things that are imaginable but not real), and that which cannot even be rationally thought. By contrast existence is often restricted solely to that which has physical existence or has a direct basis in it in the way that thoughts do in the brain. Reality is often contrasted with what is imaginary, delusional, (only) in the mind, dreams, what is false, what is fictional, or what is abstract. The truth refers to what is real, while falsity refers to what is not. Related concepts World views and theories A common colloquial usage would have reality mean "perceptions, beliefs, and attitudes toward reality," as in "My reality is not your reality." Many of the concepts of science and philosophy are often defined culturally and socially.
Pāṇini Ancient Sanskrit grammarian Pāṇini (Sanskrit: पाणिनि) (pronounced [paːɳɪnɪ], variously dated between fl. 4th century BCE; and "6th to 5th century BCE"[web 1][note 1]) was an ancient Sanskrit philologist, grammarian, and a revered scholar in ancient India. Considered "the father of linguistics", after the discovery and publication of Pāṇini's work by European scholars in the nineteenth century,[12][13] his influence on aspects of the development of modern linguists is widely recognized in the profession; his grammar was influential on foundational scholars such as Ferdinand de Saussure and Leonard Bloomfield.[14] Pāṇini likely lived in Shalatula in ancient Gandhara in the northwest Indian subcontinent, during the Mahajanapada era.[15] The name Pāṇini is a patronymic meaning descendant of Paṇina.[25] His full name was "Dakṣiputra Pāṇini" according to verses 1.75.13 and 3.251.12 of Patanjali's Mahābhāṣya, with the first part suggesting his mother's name was Dakṣi.

Being As an example of efforts in recent times, Heidegger (who himself drew on ancient Greek sources) adopted German terms like Dasein to articulate the topic.[1] Several modern approaches build on such continental European exemplars as Heidegger, and apply metaphysical results to the understanding of human psychology and the human condition generally (notably in the Existentialist tradition). By contrast, in mainstream Analytical philosophy the topic is more confined to abstract investigation, in the work of such influential theorists as W. V. O. Quine, to name one of many. "How comes the world to be here at all instead of the nonentity which might be imagined in its place?

20th century The 20th century was a century that began on January 1, 1901[1] and ended on December 31, 2000.[2] It was the tenth and final century of the 2nd millennium. It is distinct from the century known as the 1900s which began on January 1, 1900 and ended on December 31, 1999. The 20th century was dominated by a chain of events that heralded significant changes in world history as to redefine the era: flu pandemic, World War I and World War II, nuclear power and space exploration, nationalism and decolonization, the Cold War and post-Cold War conflicts; intergovernmental organizations and cultural homogenization through developments in emerging transportation and communications technology; poverty reduction and world population growth, awareness of environmental degradation, ecological extinction;[3][4] and the birth of the Digital Revolution. Overview[edit] The century had the first global-scale total wars between world powers across continents and oceans in World War I and World War II.
Becoming (philosophy) In philosophy, the concept of becoming was born in eastern ancient Greece by the philosopher Heraclitus of Hephesus, who in the Sixth century BC, said that nothing in this world is constant except change and becoming. His theory stands in direct contrast to Parmenides, another Greek philosopher, but from the italic Magna Grecia, who believed that the ontic changes or "becoming" we perceive with our senses is deceptive, and that there is a pure perfect and eternal being behind nature, which is the ultimate truth. In philosophy, the word "becoming" concerns a specific ontological concept, which should not be confused with the process philosophy, the latter indicating a metaphysical doctrine of theology. Heraclitus (c. 535 - c. 475 BC) spoke extensively about becoming. Clemens Alexandrinus (Stromata, v, 105).
