Study On The Thought Of Causality Of Schlick

The thought of causality is an important part of Schlick’s philosophy,and has some changes in the development of his philosophy.The scholars who study the thought of Schlick’s causality in China only focus on his later thoughts,but ignore his early thoughts.The early Schlick advocated that the causal relationship is about the relationship between the real things.As the description of natural events,the law of causality is strict and effective in practice,and simplicity is the causality of the standard;the late Schlick abandoned the decisive law of causality,but turned to meet a statistical regularity that has probability in nature,and regarded the statistical regularity as the imprecise causality,and the confirmation of prediction was the decisive criterion of causality.Influenced by the quantum transition in quantum mechanics,especially the uncertainty principle,Schlick did not completely abandon the law of causality,he theoretically refuted Heisenberg et al about the judgement of " the lost effectiveness of causality ",and proved the validity of the law of causality in principle,which has not been changed.In addition,the later thoughts of causality of Schlick is contradictory.On the one hand,he considered the causality as the assumption of the insignificance of understanding;on the other hand,the expression of causality are interpreted as a statement of the theoretical system could deduce other representations of axioms,which led to the expression of causality statements could have true or false nature.At the same time,he insisted that the law of causality would not lose effectiveness.With the continuous development of science,the law of causality as a statement of reality will eventually be confirmed.
