Carnap's Inductive Logic And Cognitive Meaning

In the development of modern logic, the development of Inductive logic is relatively laggard, but in the numerous embranchments of logic, inductive logic is indeed applied widely. Actually:every kind of science is based on inductive logic, in order to calculate, science puts forward hypothesis, forms specific "theory" to deduct, and then verify it. Modern inductive logic has such scientific cognition function even greater.Carnap played a significant role in the development history modern inductive logic. He inherited Keynes'thought, meanwhile, he criticized Reichenbach's inductive logic, established a great inductive logic system, This established his main status in the development of inductive logic.The dissertation analyses Carnap's inductive logic mainly from three viewpoints, finally, It focus on the influence of Carnap's inductive logic on the development of cognition.Firstly, it analyses the development of inductive logic before Carnap's times. During this times, classical inductive logic, Keynes's thought of inductive logic and reichenbach's inductive logic have a profound influence on Carnap, he inherited them and also innovated them.Secondly, the second parts of the paper detailed the content of Carnap's inductive logic, including his basic thoughts and some principles that he has advanced. Meanwhile, he compared the differences between inductive logic and deductive logic, this section also emphasized the relation between logic probability and statistic probability, they are the basis of Carnap's inductive logic.Finally, the dissertation emphasized the significance of Carnap's inductive logic and it's advance in cognitive science and cognitive logic by analyzing the value of Carnap's inductive logic in the whole development history of inductive logic.In summary, Carnap's inductive logic has great value which deserves to be researched, it's significance not only because he advanced inductive logic, but also it have profound influence on cognitive logic and cognitive science.
