摘要： 作为刑法因果关系领域的通说理论，条件说受到了条件说无用论、条件说错误论以及条件说宽松论的批评，但这些批评意见都难以成立。是否有助于查明因果关系，并不是评价包括条件说在内的刑法因果关系理论的合理标准。条件公式的确会在假定因果关系和择一因果关系的场合得出错误结论，但条件公式不等于条件说判断公式，而条件说判断公式可以在上述两种场合得出正确结论。条件说可以区分为积极条件说和消极条件说，积极条件说的确存在过于宽松的问题，但目前在理论上占据通说地位的消极条件说并不存在这个问题。

Abstract: As the most influential theory in the field of causality in criminal law, the conditions theory is subject to three typical criticisms.Firstly, it is criticized as worthless because it can not provide any help in the identification of causal relationships.Secondly, it is considered to be a wrong theory because it will draw erroneous conclusions on specific occasions.Thirdly, it is accused for leading to an overly broad scope of criminal responsibility.After a detailed analysis, we can know that the three criticisms can not be established.
