“偶然性”与“自发性”是亚里士多德自然哲学中的重要概念，在《物理学》第二卷中，亚里士多德在探讨“自然的原因”的基础上，引入了偶然性和自发性，并对这两种概念进行了详细的分析。亚里士多德肯定偶然性和自发性的存在，同时将偶然性与自发性纳入他独特的自然目的论思想之中，起到完善和补充其自然目的论的作用。

Both 'Chance' and 'Spontaneity' are important conception in Aristotle's natural philosophy. In the second volume of Physics, Aristotle introduced chance and spontaneity on the basis of his discussion of 'natural causes' and made a detailed analysis of them. Aristotle affirmed the existence of chance and spontaneity, at the same time, he included chance and spontaneity into his unique thought of natural teleology to perfect and supplement his theory of natural teleology.
