※ 引述《popandy (pop)》之銘言： : 標題: Re: The Analysis of Knowledge : 時間: Thu Oct 30 10:12:27 2003 : : ※ 引述《kinddog (為自己加加油)》之銘言： : : : : : : Gettier's Problem : : : In his short 1963 paper, "Is justified true belief knowledge?", : : : Edmund L. Gettier proposed two counterexamples to the traditional : : : analysis. In this article, Gettier intends to argue that the three : : : sufficient and necessary conditions of knowledge, in the past firmly : : : asserted by many, are indeed not sufficient for knowledge. That is to say, : : : the three conditions for a proposition P do not logically make it knowledge. : : : Gettier demonstrated that to us in the opposite way, that is, 'S knows that P' : : : is not the necessary condition for the three statements. (That A is : : : the sufficient condition for B is identical with that B is the necessary : : : condition for A.) Even though the conditions above are true, S still does : : : not know that P. thus, P is exclude from knowledge. He described two cases, : : : in which (1), (2) and (3) are true but 'S knows that P' is false, that is, : : : S do not know that P. : : : In case one, Smith believes and is justified in believing that : : : 'The man who will get the job has ten coins in his pocket', for the president : : : assured him that Jones would get the job and he had just counted the coins : : : in Jones's pocket. At last, Smith got the job and, unknown to him, he : : : happened to have ten coins in his pocket. So what Smith believes is true, : : : but Smith doesn't know it. In case two, the similar situation offers : : : the counterexample to argue that 'S knows that P' is false when the : : : alleged sufficient conditions is true. : : case2跟case1有何不同呢? : : 看不出來ㄟ : Here I do not depict the case 2, for it is similar to the case 1 : in the point that the justified belief turned out to be true : out of luck. So, the case 2, in my opinion, is the same as the case 1 : , offering a counterexample to deny the traditionally alledged : sufficient conditions for knowledge. : : : : An Alternative Approach : : : Above, we noted that the role of the justification condition is to ensure : : : that the analysis does identify as knowledge a belief that is true out of : : ^^^^ : : 我覺得這裡應該是"does not" : : 降子跟下一句話比較接的起來 : I am sure that it is 'does'. In priciple, the justification condition is to : guarantee the accuracy of the traditional analysis in identifying knowledge. : As a matter of fact, it fails to serve the purpose of guaratee. Therefore, : in the next sentence, I wrote that "the justification condition by itself : cannot ensure this." : : Thank you for your comments. 這段的第一句話意思是the justification condition is to guarantee 傳統的分析把一 個出於幸運而為真的信念當成知識.(如果是用"does") Is this what you mean ? : : luck. : : : The lesson to be learned from the Gettier problem is that the justification : : : condition by itself cannot ensure this. Even a justified belief, understood : : : as a belief based on good evidence, can be true out of luck. Thus if the : : : traditional analysis of knowledge is to exclude all cases in relation : : : to luck, it must be amended with a suitable fourth condition, a condition : : : that succeeds in the qualification of knowledge. 還有你寫的英文很簡潔 : -- :
