 For Althusser, the concept that helps to produce this understanding of scientific practices is that of the “mode of production.” With it, he argues, Marx supplied theorists with an idea sufficient to comprehend the way in which we materially produce our selves, our environments, our knowledges, and our histories. Indeed, this concept makes it possible to analyze all of our activities in their specificity and to understand them in their relation to the totality of which they are a part. As it must be if we are to make sense of scientific practice as one aspect of the total mode of production, much more than the activity of economic production must be included in this totality of productive practices. Added by Althusser to these two aspects of the mode of production are those of ideological, political, and philosophical production, among others.
