Empiricism Semantics and Ontology Carn Es imagineI. The puzzle of Abstract Entities Empiricists attempt to limit themselves to nominalistic voice communication, a oral communication non containing references to abstract entities such(prenominal) as properties, classes, relations, numbers, propositions, etc. They treat mathematics as a mere calculus wherein no interpretation is inclined or can be given. However, abstract entities argon im attainable to avoid for some scientific contexts. The establishment of meaning and truth is the problem of abstract entities in relation to semantics1. Semanticists claim that genuine looks evidence certain entities, including abstract entities2. This violates the basic principles of empiricism and leads back to a metaphysical ontology3 of the platonic mannequin. Carnap rejects the idea that the use of such manner of speaking embraces Platonic ontology, but is rather compatible with empiricism and scientific thinking. II. Linguistic Frameworks4 Carnap believes that for someone to express of a sensitive kind of entities in his talking to, he must construct a lingual cloth, a system of brand- new-fashioned ways of speaking and is subject to new rules.To understand these entities, we must recognize the twain fundamentalquestions concerning the reality of these entities (1) Internal questions or the questions of macrocosm of the new entities within the mannequin and (2) External questions or the questions of existence of the system of entities as a while. Internal questions can be answered by new images of mental synthesiss both by logical or empirical methods. External questions, on the some other hand, are in wish of a closer examination.The homo of involvements is the simplest kind of entities we deal with everyday language and upon our tole symmetryn of the social functionlanguage with its exemplar for functions, we can raise internal questions like Is there a white piece of idea on my des k? , Are unicorns real or imaginary? and these can be answered by empirical probe. The results of this investigation can be confirmed or disconfirmed based on explicit rules for the evaluation, which is the main concern of epistemology.The rules of the framework claim that in order for something to be considered real, it must fit into a system at a particular space-time continuum continuum position along with other thingsconsidered as real. The external question of the reality of the thing world is not asked by scientists but by philosophers and is given affirmative answers by realists, and negative answers from inbred idealists. This question is never resolved because it is wrongly framed. To be real in the scientific context style to be an element of the system, hence, this concept cannot be meaningfully applied to the system.Those who question the reality of the thing world are not expecting of a theory-based question, rather, a practical question whichwould affect the cons truction of our language hence, we must decide whether or not to adapt the forms of expression in the framework. We have accepted the thing language since our earlier years and now we are given the choice whether or not to sustain using the thing language or to restrict ourselves to sense-date, to construct an alternative language with new structure and rules, or to refrain from speaking at all.However, Carnap believes that none of the above-mentioned choices is practical. So, he explained that theacceptance of the thing language does not imply the acceptance of the existence of the thing world, but the acceptance of a certain form of language, accepting rules in order to form, test, or reject statements, and the idea of the reality of the thing world cannot be among these statements because it cannot be formulated in the thing language or in any other theoretical language. Questions regarding the efficiency, fruitfulness and simplicity of the use of the thing language are not yes- no questions but rather questions of degree. scarcely it is wrong to say that The fact of the efficiency of the thing language is confirming evidence for the reality of the thing world, rather, This fact makes it advisable to accept the thing language. Carnap apply the use of the system of numbers as an slip of a system which is of a logical rather than a factual nature, based on the rules of the new expressions 1 SEMAN?

(1) numerals like five and curse forms like there are five books on the table (2) the general term number for th e new entities, and sentence forms like five is a number (3) expressions of properties of numbers (odd, prime), relations ( great than), and functions (plus), and sentence forms like dickens plus lead is five. (4) numerical variables (m,n,etc) and quantifiers for universal sentences (for every n,. ) and existential sentences (there is an n such that) with the customary deductive rules Empirical investigation is impossible to answer the internal question, Is there a prime number greater than a hundred? , rather it can be answered through logical analysis. He also introduced the system of propositions wherein any declarative sentence can be substituted by a variable. Every sentence that comes in the form is a proposition is considered uninflected.This framework included three constructs (1) For every p, either p or not p (2) There is p such that p is not necessary and not p is not necessary. (3) There is p such that p is a proposition. (1) and (2) are both internal assertions of ex istence while (3) is an implication that there are propositions. Lastly, in the spatio- blase coordinate system for physics, the new entities are the space-time points. Each point is an ordered quadruple of four real numbers (3 spatial and 1 temporal coordinate). It is not forced on us but is suggested by common observation.The physical state of these space-time points is described through qualitative predicates or through ascribing numbers such as mass, temperature, etc. move on to this physical coordinate system requires a decision on how to use language. Carnap argues that the introduction of such forms into our language is a matter of degree, and that the formulation in the form real or not leave alone be inadequate. Many philosophers argue that the affirmation of the reality of the entity of the language shall come prior to the introduction of new language forms, and Carnap strongly disagrees.He claims that a new way of speaking needs not be justified because in the first pla ce, it does not imply any assertion of reality, but lone(prenominal) acceptance of a new framework. III. What Does Acceptance of a Kind of Entities Mean? The acceptance of a new kind of entities is represented in the language by the introduction of a framework of new forms of expressions to be used according to a new set of rules.The two essential steps into the introduction of the framework are (1) the introduction of a general term, a predicate of higher level, for the new kind of entities, permitting us to say of any particular entity that itbelongs to this kind5 and (2) the introduction of variables of the new type. After the formulation of the new forms of language, they can now realise internal questions that may either be empirical or logical, and be addressed by genuine answers that are either factually on-key or analytic.Carnap debunks the idea that the acceptance of a new framework is an assertion of the reality of the entities. He argues that the question whether or no t to accept the new entities and the new linguistic form is a practical question and not a theoretical question.It cannot be judged as true or false because it is not an assertion, rather, it can be judged as being more or less(prenominal) expedient, fruitful and conducive. IV. Abstract Entities in Semantics In semantical meaning analysis, certain expressions are often said to designate (or name or denote or signify) certain extra- linguistic entities. Ex. The word red designates a quality of things. The word five designates a number. Empiricists admit that these are meaningful expressions but reject the belief as they see these as implicitly presupposed by those semantical statements. 5 E. G.RED IS A PROPERTY, FIVE IS A NUMBER This belief is criticized as hypostatization, or treating as call expressions which are not names. Carnap used the example of Fido, his dog, as a name that designates his dog Fido, while red and five are not names and are not supposed to designate anythin g. To deal with this criticism, Carnap clarifies abstract entities as designata (a) Five designates a number. This presupposes that our language L contains the forms of expressions which we have called the framework of numbers, in particular, numerical variables and the general term number.If L contains these forms, the sideline is an analytic statement in L. (b) Five is a number. To make the statement (a) possible, L must contain an expression like designates or is a name of for the semantical relation of designation. If suitable rules for this term are laid down, the following is likewise analytic (c) Five designates five. Since (a) follows from (c) and (b), (a) is likewise analytic. You must accept these as true statements if you accept the framework of numbers.Carnap acknowledges the need for theoretical justification for internal assertions but argues that it is wrong to demand forsu ch when it comes to acceptance of system of entities. He cites Ernest Nagel who asked for e vidence relevant for affirming with warrant that there are such entities as infinitesimals or propositions. He take the evidence to be logical and dialectical.And so Carnap provides an example of this problem of proof Here are three books. The framework of the sentence allows us to communicate but the question on the ontological reality of the system of numbers continues. One philosopher believes that numbers are real entities so there is no problem in using thenumerical framework for semantical statements. A nominalistic opponent, on the other hand, says there are no numbers. For Carnap, numbers may still be used as meaningful expressions but they are not names and there are no entities designated by them.The term numbers and numerical variables must only be used as abbreviating devices i. e. to translate them into the nominalistic thing language. He believes that there is no possible evidence relevant for both philosophers. V. Conclusion Carnaps stand on using semantical method s depended not on the ontological question of existence of abstract entities but onthe qu estion whether or not the rise of abstract linguistic forms is expedient and fruitful for semantical analyses6.This is no yes-or-no question. It dealt with a matter of degree, by their efficiency as instruments, by the . . ratio of the results achieved to the amount and complexity of the efforts required. He challenges the nominalists to offer better arguments than merely appealing to ontological insight plausibly a semantical method without any references at all to abstract entities and by simpler means, achieves the same results as other methods.Carnappointed out that dogmatic prohibitions are both futile and harmful that looking back to history, traces of slow phylogenesis rooted to religious, metaphysical, mythological, and other irrational sources. And so by granting freedom to use any form of expression useful to them, those useless forms will sooner or later be eliminated. Carnap ende d with a reminder, allow us be cautious in making assertions and critical in examining them, but tolerant in permitting linguistic forms. 6 SEMAN?
