James Kreines's Reason in the World (2015) offers an engaging and thought-provoking examination of Hegel's ambitions in the Science of Logic. However, it has gone unnoticed that there are two fundamental misinterpretations in his account of ‘Mechanism’ from the Logic. First, Kreines interprets the chapter as beginning with a ‘pure mechanism’ hypothesis that investigates the coherence of a purely mechanistic explanation of the world that makes no appeal to the immanent concept of things. Thus, according to Kreines, the Concept is (...) absent from the beginning of ‘Mechanism’ and only appears in the final section of the chapter, in ‘C. Absolute Mechanism’ in the subsection on the law, what Kreines conceptualizes as ‘reasonable mechanism’. Second, within his overall interpretation of ‘Mechanism’ as the development from the ‘pure mechanism’ hypothesis to ‘reasonable mechanism’ Kreines claims that there are logical moments that are explanatorily relevant and some that are not. Thus, Kreines will want to claim that Hegel's analysis of ‘pure mechanism’ reveals that ‘pure mechanism’ fails to be explanatorily relevant because, a) the logical moments do not have a concept immanent to them, and b) have ‘indifference’. It is only in the law that mechanistic explanations become explanatorily relevant because of the appearance of the Concept and the disappearance of ‘indifference’. I argue against both these positions. First, I think that there is no textual support for the idea that ‘Mechanism’ begins without the Concept immanent to it. Second, I think that Kreines is mistaken to equate ‘indifference’ with explanatory irrelevance and the absence of the Concept. My approach in this paper is to give my own analysis of the relevant passages from ‘Mechanism’ and, in doing so, to both show the misgivings of Kreines's interpretation and to offer an alternative way of reading the chapter.
