A Study Of Nudgrim 's Anti - Factual Conditional Sentences

Nelson. Goodman (Nelson Goodman) Americans, the famous philosopher andlogician. The main representative of "counterfactual conditionals Dilemma" in1946on "Science" published, the article mainly reflects the understanding of the relevantcounterfactual Goodman authenticity determination, and proposed two anti-factdifficulties, this article once published it caused a lot of logical discussion inacademic circles, counterfactual conditionals for related problems and to find ways tosolve the problem of counterfactual conditionals, causing the majority of logiciansrepercussions.Expand Goodman material implication in classical logic on the basis ofcounterfactual conditionals true, false standards determine the question, and thus thecounterfactual conditionals true, false research, and presents two counterfactualpredicament. Material implication is (including counterfactual conditionals) and agenuine relationship between the pieces to determine conditional sentence based onantecedent conditions (including counterfactual conditionals) of the true value. Inaccordance with the substance of the implication of view: a sentence as long as theantecedent condition is false, this proposition is true propositions. However, thesimple explanation is that a counterfactual conditional sentence antecedentcounterfactual conditionals, if the criteria used to determine the substance contains"counterfactual conditionals " is the " antecedent is false," the conditions of thesentence is true forever proposition. For this view, Goodman cited many examples inlife, to find the facts on anti-determination of true and false sentences, according to" another way " belief that their ideas, suggestions counterfactual conditionalsagainst "true the new guidelines,"the understanding, try to solve the plight of thetwo counterfactual conditionals. But due to the demonstration and validation endlesscycle encountered problems, he conceived the theory is not able to give a good finalsolution to the plight of counterfactual conditionals answer. But do not thinkGoodman is the fuss live, even though he was not able to last a good solution to theplight of two counterfactual sentence, but he exploded some problems counterfactualconditionals, found, for example, to the past, after coupling member and the relationship between the laws of science point of departure for the study ofcounterfactual. It is precisely because of his persistence and hard before allowingfurther behind logicians of counterfactual conditionals studied on the basis of hisresearch.This paper is mainly on the counterfactual conditions of N Goodman’s words, isdivided into four parts to explain N Goodman’s counterfactual thinking: the firstchapter is the brief introduction of Goodman’s life story, he exhibition and to hiscounterfactual thought origin; any thoughts or theories have a certain source, therewill be after the development of the source, can be said is an important basis offorming ideas, so the use of a certain length to the source is necessary, but also tostrengthen the understanding of Goodman’s counterfactual thoughts on. In the secondchapter, focuses on two related questions proposed by Goodman’s "counterfactualconditionals in problem" of the show, in the predicament that also contains his on andsolutions counterfactual analysis. This emphasizes the counterfactual thought is animportant part in the logical thought of Goodman; in this chapter, mainly have arough outline of counterfactual thinking will be Goodman, for he had done to thecounterfactual problem of solving attempts, the relevant contents of thecounterfactual problem to have an accurate grasp of. The third part, a lot of space todisplay counterfactual conditions on Goodman’s words were analyzed, theconnectives counterfactual sentences, and related rules of inference of counterfactualconditionals and counterfactual sentences facts are introduced briefly. In the fourthchapter, focuses on the new thinking of counterfactual conditionals, furtherelaboration of new thinking, this is the biggest, which includes the analysis ofcounterfactual conditionals in point of time, to illustrate the application ofcounterfactual conditionals in time by the common support theory and similaritytheory. This will help to interpret our counterfactual thoughts of Goodman.
