进化规律的可能性与必要性

On the Possibility and the Necessity of Evolutionary Laws

如果规律是关于倾向性的陈述 ,那么 ,科学理论的建构就应被理解为主要是阐释这种倾向性的初始和边界条件的活动。依据这种条件被阐释的程度 ,可以说明进化规律的可能性。即使按照语义观 ,科学解释也要求经验规律 ,因为仅有模型与数据的适合还不足以说明经验系统的因果结构。所以 ,进化规律对于保证进化论的科学地位又是必要的。

If a law is a statement about the tendency, we must understand the principal task in constructing scientific theories as to specify the initial and boundary conditions under which the tendency appearing. According to the degree of specifying, we can account of the possibility of evolutionary law. Explanations on the semantic view also require the existence of empirical laws, because the fit between model and data cannot specify the causal structure in a empirical system. Thus evolutionary laws are necessary for saving evolutionary theory.
