贝内特从“实践”的层次对阿尔都塞的文学理论观点进行了分析和探试。在他看来，阿尔都塞的“实践”层次是一种相对的自主体，“是对一定的原料改造成一定产品的过程”，科学、文学和意识形态这三种实践形式就是通过对一定的原料发生影响而以认识效应、美学效应、思想效应为特征的劳动产品。而这些效应是永恒不变的认识形式。因此，在贝内特看来，阿尔都塞的“物质实践”在其本质上是认识形式的恒定结构的表现。 Bennett analyzed and explored Althusser’s literary theory from the “practical” level. In his view, Althusser’s “practice” level is a relative autonomy, “a process of transforming certain raw materials into products,” and the three forms of practice of science, literature and ideology are through a certain The impact of raw materials to cognitive effects, aesthetic effects, ideological and labor features characterized by the product. And these effects are eternal forms of cognition. Therefore, in Bennett’s opinion, Althusser’s “material practice” is essentially a manifestation of the constant structure of the form of cognition.
