The existence and necessity of causal relations are not always doubted in daily life, yet it puzzled us more than once in field of philosophical reflections. As the problems of epistemology, these puzzles are beginning from David Hume, because he not only gave his suspicions of the necessity of causes at the aspects of experience, but also oppugned the necessity of causes at the aspects of logic by his arguments.The analytical philosophy has great contributions to epistemology, and it is because of changing the mode of asking questions first. Then in the opinions of analytical philosopher, before asking "What is truth?" we have not answered the question that can we give a true answer to these kinds of questions, namely "Can we say out the truth exactly?" we can also ask the question like this: before asking "What is the causal relations?", can we express the causal relations exactly? So we should analyze our expressions of causal relations at first.Hume's argumentation of non-necessity of causal relations will be as the object of this paper, and I will give an explanation of this argumentation by using words of modern philosophy in the way of analysis, and I will also give the reason why Davidson's theory of action reasons has its superiority on explaining this argumentation and on explaining causal relations moreover. Finally the argument of Davidson's view about the non-necessity of causal relations will be given. Thus the structure of this paper will be given as follow:In chapter one the object of analysis, Hume's argumentation of non-necessity of causal relations, will be given, together with a preparatory illumination on this argumentation. In chapter two some traditional philosophy views on this argumentation will be shown, and "the drift toward Descartes" on the mode of argument will be treated as the emphasis of analysis. In chapter three the question under the view of reference theory will be talked about, including the alteration of concept and the invalidation of the principle of Hume's argumentation. In chapter four, the question that how does Davidson build the meaning theory on the basis of con-reference theory will be explained. In chapter five, the final one, the process of Davidson building his theory of action reasons will be shown, and after that I will analyze Davidson's view on Hume's argumentation on the theory of action reasons basis, and I will analyze the primary view of causal relations which is given by Davidson's theory, before showing the advantage of this theory. |
