CONCEPT概念的诸多释义
CONCEPT概念的诸多释义ConceptA.From WikipediaA concept is an abstraction or generalisation from experience or the result of a transformation of existing ideas.The concept is instantiated(reified)by all of its actual or potential instances,whether these are things in the real world or other ideas. Concepts are treated in many if not most disciplines both explicitly,such asin linguistics,psychology,philosophy,etc.,and implicitly,such asin mathematics,physics,etc.In informal use the word concept often just meansany idea,but formally it involves the abstraction component.When the mind makes a generalization such as the concept of tree,it extractssimilarities from numerous examples;the simplification enables higher-levelthinking.In metaphysics,and especially ontology,a concept is a fundamental category of existence.In contemporary philosophy,there are at least three prevailing ways to understand what a concept is:Concepts as mental representations,where concepts are entities that exist in the brain(mental objects)Concepts as abilities,where concepts are abilities peculiar to cognitive agents (mental states)Concepts as Fregean senses(see sense and reference),where concepts are abstract objects,as opposed to mental objects and mental states Embodied contentMain article:Embodied cognitionIn cognitive linguistics,abstract concepts are transformations of concrete concepts derived from embodied experience.The mechanism of transformation is structural mapping,in which properties of two or more source domains are selectively mapped onto a blended space(Fauconnier&Turner,1995;see conceptual blending).A common class of blends are metaphors.Abstract objectsMain article:Abstract objectIn a platonist theory of mind,concepts are construed as abstract objects.This debate concerns the ontological status of concepts–what they are really like.In the simplest terms,a concept is a name or label that regards or treats an abstraction as if it had concrete or material existence.I t is important to realizethat a concept is merely a symbol,a representation of the abstraction.The word is not to be mistaken for the thing.For example,the word"moon"(a concept)is not the large,bright,shape-changing object up in the sky,but only represents that celestial object.Concepts are created(named)to describe,explain and capture reality as it is known and understood.A priori conceptsMain articles:A priori and a posteriori and Category(Kant)Kant declared that human minds possess pure or a priori concepts.Instead of being abstracted from individual perceptions,like empirical concepts,they originate in the mind itself.He called these concepts categories,in the sense of the word that means predicate,attribute,characteristic,or quality.But these pure categories are predicates of things in general,not of a particular thing.He called those concepts that result from abstraction"a posteriori concepts"(meaning concepts that arise out of experience).An empirical or an a posteriori concept is a general representation (Vorstellung)or non-specific thought ofthat which is common to several specific perceived objects(Logic,I,1.,§1,Note1)A concept is a common feature or characteristic.Kant investigated the way that empirical a posteriori concepts are created. The logical acts of the understanding by which concepts are generatedas to their form are:/doc/00c369d732d4b14e852458fb770bf78a65293a00.html parison,i.e.,the likening of mental images to one another inrelation to the unity of consciousness;2.reflection,i.e.,the going back over different mental images,howthey can be comprehended in one consciousness;and finally3.abstraction or the segregation of everything else by which themental images differ...In order to make our mental images into concepts,onemust thus be able to compare,reflect,and abstract,forthese three logical operations of the understanding areessential and general conditions of generating anyconcept whatever.OntologyMain article:OntologyPlato was the starkest proponent of the realist thesis of universal concepts.By his view,concepts(and ideas in general)are innate ideas that were instantiations of a transcendental world of pure forms that lay behind the veil of the physical world.In this way,universals were explained as transcendent objects.Main article:Mental representationIn a physicalist theory of mind,a concept is a mental representation,which the brain uses to denote a class of things in the world.This is to say that it is literally,a symbol or group of symbols together made from the physical material of the brain. Concepts are mental representations that allow us to draw appropriate inferences about the type of entities we encounter in our everyday lives.Concepts do not encompass all mental representations,but are merely a subset of them.The use of concepts is necessary to cognitive processes suchas categorization,memory,decision making,learning,and inference.Classical theoryMain article:DefinitionismThe classical theory of concepts,also referred to as the empiricist theory of concepts, is the oldest theory about the structure of concepts(it can be traced back to Aristotle), and was prominently held until the1970s.The classical theory of concepts says that concepts have a definitional structure.Adequate definitions of the kind required by this theory usually take the form of a list of features.These features must have two important qualities to provide a comprehensive definition.Features entailed by the definition of a concept must be both necessary and sufficient for membership in the class of things covered by a particular concept.A feature is considered necessary if every member of the denoted class has that feature.A feature is considered sufficient if something has all the parts required by the definition.Another key part of this theory is that it obeys the law of the excluded middle,which means that there are no partial members of a class,you are either in or out.Prototype theoryMain article:Prototype theoryPrototype theory says that concepts specify properties that members of a class tend to possess,rather than must possess.Wittgenstein describes the relationship between members of a class as family resemblances.There are not necessarily any necessary conditions for membership,a dog can still be a dog with only three legs. This view is particularly supported by psychological experimental evidence for prototypicality effects.We can judge an item's membership to the referent class of a concept by comparing it to the typical member–the most central member of the concept.If it is similar enough in the relevant ways,it will be cognitively admitted as a member of the relevant class of entities.Rosch suggests that every category is represented by a central exemplar which embodies all or the maximum possible number of features of a given category.Theory-theoryThis theory postulates that categorization by concepts is something like scientific theorizing.Concepts are not learned in isolation,but rather are learned as a part of ourexperiences with the world around us.In this sense,concepts'structure relies on their relationships to other concepts as mandated by a particular mental theory about the state of the world.According to the theory of ideasthesia(or"sensing concepts"),activation of a concept may be the main mechanism responsible for creation of phenomenal experiences.Therefore,understanding how the brain processes concepts may be central to solving the mystery of how conscious experiences(or qualia)emerge within a physical system e.g.,the sourness of the sour taste of lemon.This question is also known as the hard problem of consciousness.Research on ideasthesia emerged from research on synesthesia where it was noted that a synesthetic experience requires first an activation of a concept of the /doc/00c369d732d4b14e852458fb770bf78a65293a00.html ter research expanded these results into everyday perception.B.From Sci-tech encyclopediaConcept1.International Dictionary of Psychoanalysis|2005|Luzes,PedroCOPYRIGHT2005Thomson Gale.For Wilfred Bion,conception is the result of coupling a pre-conception,an innate a priori idea,and a realization,elements of the real that are provided by external-sensory or internal-emotional experience.The concept is derived from conception through abstraction and /doc/00c369d732d4b14e852458fb770bf78a65293a00.html nguage and the attribution of a name to a concept unite preconception and realization,preventing any loss of experience in the process.Bion considers the concept a conception that has been assigned a name.The concept signifies a growth of the abstraction that enables us to expand the generalization of psychoanalytic theories,which,as a whole are judged to be too descriptive,tooconcrete.Concepts can be articulated in a deductive scientific system that functions like an Ars combinatoria2.The Oxford Pocket

concept和reference的例子
concept和reference的例子
在学术写作中,概念(Concept)和参考文献(Reference)是其中两个重要的元素。
概念指的是创造性思维的产物,是对事物、现象或观点的抽象概括和理解,而参考文献是对所参考的文献资料的引用和列举。
举一个概念的例子,我们可以考虑“社会责任感”这个概念。
社会责任感可以定义为个人或组织对社会问题承担责任的意识和行动。
在学术写作中,可以通过对社会责任感的定义、特征和影响等方面进行深入研究。
通过概念的引用和阐述,我们能够更好地理解和解释这个概念,并将其应用于相关领域。
参考文献的例子是在学术论文或研究报告中引用的文献资料。
参考文献的作用是为了支持和证明所提出的观点和研究成果的可靠性。
例如,在一篇关于环境污染对健康的研究中,研究人员可能会引用过去的研究、科学报告或相关政策文件作为参考文献。
通过引用可靠的参考文献,读者可以追溯并确认研究的依据和可信度。
要注意的是,引述的参考文献应该来源于权威和可信的出版物,如学术期刊、书籍或政府机构发布的报告。
在学术写作中,正确引用参考文献的格式也是非常重要的,通常遵循特定的引用规范,如APA、MLA或Chicago等。
总结起来,概念和参考文献是学术写作中不可或缺的组成部分。
通过清晰阐述和定义概念,研究人员能够深入探索和解释特定的主题。
同时,正确引用和列举参考文献可以增加研究的可信度和可靠性。

ConceptA.From WikipediaA concept is an abstraction or generalisation from experience or the result of a transformation of existing ideas.The concept is instantiated(reified)by all of its actual or potential instances,whether these are things in the real world or other ideas. Concepts are treated in many if not most disciplines both explicitly,such asin linguistics,psychology,philosophy,etc.,and implicitly,such asin mathematics,physics,etc.In informal use the word concept often just meansany idea,but formally it involves the abstraction component.When the mind makes a generalization such as the concept of tree,it extractssimilarities from numerous examples;the simplification enables higher-levelthinking.In metaphysics,and especially ontology,a concept is a fundamental category of existence.In contemporary philosophy,there are at least three prevailing ways to understand what a concept is:∙Concepts as mental representations,where concepts are entities that exist in the brain(mental objects)∙Concepts as abilities,where concepts are abilities peculiar to cognitive agents (mental states)∙Concepts as Fregean senses(see sense and reference),where concepts are abstract objects,as opposed to mental objects and mental states Embodied contentMain article:Embodied cognitionIn cognitive linguistics,abstract concepts are transformations of concrete concepts derived from embodied experience.The mechanism of transformation is structural mapping,in which properties of two or more source domains are selectively mapped onto a blended space(Fauconnier&Turner,1995;see conceptual blending).A common class of blends are metaphors.Abstract objectsMain article:Abstract objectIn a platonist theory of mind,concepts are construed as abstract objects.This debate concerns the ontological status of concepts–what they are really like.In the simplest terms,a concept is a name or label that regards or treats an abstraction as if it had concrete or material existence.I t is important to realizethat a concept is merely a symbol,a representation of the abstraction.The word is not to be mistaken for the thing.For example,the word"moon"(a concept)is not the large,bright,shape-changing object up in the sky,but only represents that celestial object.Concepts are created(named)to describe,explain and capture reality as it is known and understood.A priori conceptsMain articles:A priori and a posteriori and Category(Kant)Kant declared that human minds possess pure or a priori concepts.Instead of being abstracted from individual perceptions,like empirical concepts,they originate in the mind itself.He called these concepts categories,in the sense of the word that means predicate,attribute,characteristic,or quality.But these pure categories are predicates of things in general,not of a particular thing.He called those concepts that result from abstraction"a posteriori concepts"(meaning concepts that arise out of experience).An empirical or an a posteriori concept is a general representation (Vorstellung)or non-specific thought of that which is common to several specific perceived objects(Logic,I,1.,§1,Note1)A concept is a common feature or characteristic.Kant investigated the way that empirical a posteriori concepts are created.The logical acts of the understanding by which concepts are generatedas to their form are:parison,i.e.,the likening of mental images to one another inrelation to the unity of consciousness;2.reflection,i.e.,the going back over different mental images,howthey can be comprehended in one consciousness;and finally3.abstraction or the segregation of everything else by which themental images differ...In order to make our mental images into concepts,onemust thus be able to compare,reflect,and abstract,forthese three logical operations of the understanding areessential and general conditions of generating anyconcept whatever.OntologyMain article:OntologyPlato was the starkest proponent of the realist thesis of universal concepts.By his view,concepts(and ideas in general)are innate ideas that were instantiations of a transcendental world of pure forms that lay behind the veil of the physical world.In this way,universals were explained as transcendent objects.Main article:Mental representationIn a physicalist theory of mind,a concept is a mental representation,which the brain uses to denote a class of things in the world.This is to say that it is literally,a symbol or group of symbols together made from the physical material of the brain. Concepts are mental representations that allow us to draw appropriate inferences about the type of entities we encounter in our everyday lives.Concepts do not encompass all mental representations,but are merely a subset of them.The use of concepts is necessary to cognitive processes suchas categorization,memory,decision making,learning,and inference.Classical theoryMain article:DefinitionismThe classical theory of concepts,also referred to as the empiricist theory of concepts, is the oldest theory about the structure of concepts(it can be traced back to Aristotle), and was prominently held until the1970s.The classical theory of concepts says that concepts have a definitional structure.Adequate definitions of the kind required by this theory usually take the form of a list of features.These features must have two important qualities to provide a comprehensive definition.Features entailed by the definition of a concept must be both necessary and sufficient for membership in the class of things covered by a particular concept.A feature is considered necessary if every member of the denoted class has that feature.A feature is considered sufficient if something has all the parts required by the definition.Another key part of this theory is that it obeys the law of the excluded middle,which means that there are no partial members of a class,you are either in or out.Prototype theoryMain article:Prototype theoryPrototype theory says that concepts specify properties that members of a class tend to possess,rather than must possess.Wittgenstein describes the relationship between members of a class as family resemblances.There are not necessarily any necessary conditions for membership,a dog can still be a dog with only three legs. This view is particularly supported by psychological experimental evidence for prototypicality effects.We can judge an item's membership to the referent class of a concept by comparing it to the typical member–the most central member of the concept.If it is similar enough in the relevant ways,it will be cognitively admitted as a member of the relevant class of entities.Rosch suggests that every category is represented by a central exemplar which embodies all or the maximum possible number of features of a given category.Theory-theoryThis theory postulates that categorization by concepts is something like scientific theorizing.Concepts are not learned in isolation,but rather are learned as a part of ourexperiences with the world around us.In this sense,concepts'structure relies on their relationships to other concepts as mandated by a particular mental theory about the state of the world.According to the theory of ideasthesia(or"sensing concepts"),activation of a concept may be the main mechanism responsible for creation of phenomenal experiences.Therefore,understanding how the brain processes concepts may be central to solving the mystery of how conscious experiences(or qualia)emerge within a physical system e.g.,the sourness of the sour taste of lemon.This question is also known as the hard problem of consciousness.Research on ideasthesia emerged from research on synesthesia where it was noted that a synesthetic experience requires first an activation of a concept of the ter research expanded these results into everyday perception.B.From Sci-tech encyclopediaConcept1.International Dictionary of Psychoanalysis|2005|Luzes,PedroCOPYRIGHT2005Thomson Gale.For Wilfred Bion,conception is the result of coupling a pre-conception,an innate a priori idea,and a realization,elements of the real that are provided by external-sensory or internal-emotional experience.The concept is derived from conception through abstraction and nguage and the attribution of a name to a concept unite preconception and realization,preventing any loss of experience in the process.Bion considers the concept a conception that has been assigned a name.The concept signifies a growth of the abstraction that enables us to expand the generalization of psychoanalytic theories,which,as a whole are judged to be too descriptive,too concrete.Concepts can be articulated in a deductive scientific system that functions like an Ars combinatoria2.The Oxford Pocket Dictionary of Current English|2009©The Oxford Pocket Dictionary of Current
