In any of several fields of study that treat the use of signs—for example, in linguistics, logic, mathematics, semantics, semiotics, and philosophy of language—an intension is any property or quality connoted by a word, phrase, or another symbol. In the case of a word, the word's definition often implies an intension. For instance, the intensions of the word plant include properties such as "being composed of cellulose ", "alive", and "organism", among others. A comprehension is the collection of all such intensions.
The meaning of life pertains to the inherent significance or philosophical meaning of living. There is not a definitive answer, and thinking or discourse on the topic is sought in the English language through the question, "What is the meaning of life?". There have been many proposed answers to these questions from many different cultural and ideological backgrounds. The search for life's meaning has produced much philosophical, scientific, theological, and metaphysical speculation throughout history. Different people and cultures believe different things for the answer to this question. Opinions vary on the usefulness of using time and resources in the pursuit of an answer. Excessive pondering can be indicative of, or lead to, an existential crisis.
Nihilism is a family of views within philosophy that rejects generally accepted or fundamental aspects of human existence, such as knowledge, morality, or meaning. The term was popularized by Ivan Turgenev and more specifically by his character Bazarov in the novel Fathers and Sons.
A sign is an object, quality, event, or entity whose presence or occurrence indicates the probable presence or occurrence of something else. A natural sign bears a causal relation to its object—for instance, thunder is a sign of storm, or medical symptoms a sign of disease. A conventional sign signifies by agreement, as a full stop signifies the end of a sentence; similarly the words and expressions of a language, as well as bodily gestures, can be regarded as signs, expressing particular meanings. The physical objects most commonly referred to as signs generally inform or instruct using written text, symbols, pictures or a combination of these.
Semiotics is the systematic study of sign processes and the communication of meaning. In semiotics, a sign is defined as anything that communicates intentional and unintentional meaning or feelings to the sign's interpreter.
Absurdism is the philosophical theory that the universe is irrational and meaningless. It states that trying to find meaning leads people into a conflict with the world. This conflict can be between rational man and an irrational universe, between intention and outcome, or between subjective assessment and objective worth, but the precise definition of the term is disputed. Absurdism claims that existence as a whole is absurd. It differs in this regard from the less global thesis that some particular situations, persons, or phases in life are absurd.
Semiosis, or sign process, is any form of activity, conduct, or process that involves signs, including the production of meaning. A sign is anything that communicates a meaning, that is not the sign itself, to the interpreter of the sign. The meaning can be intentional such as a word uttered with a specific meaning, or unintentional, such as a symptom being a sign of a particular medical condition. Signs can communicate through any of the senses, visual, auditory, tactile, olfactory, or taste.
In semiotics, a sign is anything that communicates a meaning that is not the sign itself to the interpreter of the sign. The meaning can be intentional, as when a word is uttered with a specific meaning, or unintentional, as when a symptom is taken as a sign of a particular medical condition. Signs can communicate through any of the senses, visual, auditory, tactile, olfactory, or taste.
In semiotics, the value of a sign depends on its position and relations in the system of signification and upon the particular codes being used.
Representation is the use of signs that stand in for and take the place of something else. It is through representation that people organize the world and reality through the act of naming its elements. Signs are arranged in order to form semantic constructions and express relations.
In semiotics and discourse analysis, floating signifiers are signifiers without a referent. The term open signifier is sometimes used as a synonym due to the empty signifier's nature to "resist the constitution of any unitary meaning", enabling its ability to remain open to different meanings in different contexts.
In psychology and psychotherapy, existential crises are inner conflicts characterized by the impression that life lacks meaning or by confusion about one's personal identity. Existential crises are accompanied by anxiety and stress, often to such a degree that they disturb one's normal functioning in everyday life and lead to depression. This negative attitude towards life and meaning reflects various positions characteristic of the philosophical movement known as existentialism. Synonyms and closely related terms include existential dread, existential vacuum, existential neurosis, and alienation. The various aspects associated with existential crises are sometimes divided into emotional, cognitive, and behavioral components. Emotional components refer to the feelings they provoke, such as emotional pain, despair, helplessness, guilt, anxiety, or loneliness. Cognitive components encompass the problem of meaninglessness, the loss of personal values or spiritual faith, and reflections about one's own mortality. Outwardly, existential crises often express themselves in addictions, anti-social and compulsive behavior.
Articulatory gestures are the actions necessary to enunciate language. Examples of articulatory gestures are the hand movements necessary to enunciate sign language and the mouth movements of speech. In semiotic terms, these are the physical embodiment (signifiers) of speech signs, which are gestural by nature.
Charles Sanders Peirce began writing on semiotics, which he also called semeiotics, meaning the philosophical study of signs, in the 1860s, around the time that he devised his system of three categories. During the 20th century, the term "semiotics" was adopted to cover all tendencies of sign researches, including Ferdinand de Saussure's semiology, which began in linguistics as a completely separate tradition.
Social semiotics is a branch of the field of semiotics which investigates human signifying practices in specific social and cultural circumstances, and which tries to explain meaning-making as a social practice. Semiotics, as originally defined by Ferdinand de Saussure, is "the science of the life of signs in society". Social semiotics expands on Saussure's founding insights by exploring the implications of the fact that the "codes" of language and communication are formed by social processes. The crucial implication here is that meanings and semiotic systems are shaped by relations of power, and that as power shifts in society, our languages and other systems of socially accepted meanings can and do change.
Figurae are the non-signifying constituents of signifiers (signs). For example, letters of the alphabet are the figurae that comprise a written word (signifier). In the semiotic language of Louis Hjelmslev, the coiner of this term, figurae serve only to distinguish elements of the expression plane from each other, independently from the content plane. That is, the letter B, in the written word expression "bat", distinguishes "bat" from the word "sat", but neither B nor S bears meaning on its own. On the other hand, the constituents "foot" and "ball" both bear their own individual meanings, such that in the word "football", they cannot be considered figurae, although their individual letters can. Hjelmslev states that in a given language a "legion of signs" can be constructed with a "handful of figurae" through ever new arrangements of them. Linguists often use the terms phonemes and morphemes to refer, respectively, to the figurae and the signifiers of human languages.
Existential nihilism is the philosophical theory that life has no objective meaning or purpose. The inherent meaninglessness of life is largely explored in the philosophical school of existentialism, where one can potentially create their own subjective "meaning" or "purpose". The supposed conflict between our desire for meaning and the reality of a meaningless world is explored in the philosophical school of absurdism. Of all types of nihilism, existential nihilism has received the most literary and philosophical attention.
The paradox of nihilism is a family of paradoxes regarding the philosophical implications of nihilism, particularly situations contesting nihilist perspectives on the nature and extent of subjectivity within a nihilist framework. There are a number of variations of this paradox.
In semiotics, signified and signifier are the two main components of a sign, where signified is what the sign represents or refers to, known as the "plane of content", and signifier which is the "plane of expression" or the observable aspects of the sign itself. The idea was first proposed in the work of Swiss linguist Ferdinand de Saussure, one of the two founders of semiotics.
Importance is a property of entities that matter or make a difference. For example, World War II was an important event and Albert Einstein was an important person because of how they affected the world. There are disagreements in the academic literature about what type of difference is required. According to the causal impact view, something is important if it has a big causal impact on the world. This view is rejected by various theorists, who insist that an additional aspect is required: that the impact in question makes a value difference. This is often understood in terms of how the important thing affects the well-being of people. So in this view, World War II was important, not just because it brought about many wide-ranging changes but because these changes had severe negative impacts on the well-being of the people involved. The difference in question is usually understood counterfactually as the contrast between how the world is and how the world would have been without the existence of the important entity. It is often argued that importance claims are context- or domain-dependent. This means that they either explicitly or implicitly assume a certain domain in relation to which something matters. For example, studying for an exam is important in the context of academic success but not in the context of world history. Importance comes in degrees: to be important usually means to matter more within the domain in question than most of the other entities within this domain.
