 Another complaint has been that mechanistic explanations fail to provide a satisfactory account of the complexity of living systems because they fail to devote serious attention to the “thoroughly processual character of living systems” (Dupre 2012: 19). Those who prefer a “process-oriented” ontology (Bapteste and Dupre 2013; Bickhard 2011; Campbell 2015; Dupre 2012; Jaeger and Monk 2015; Jaeger et al. 2012; Meincke 2018; Nicholson and Dupre 2018) argue that mechanistic accounts mistakenly assume that parts composing a mechanism can be identified independently of the activities or processes in which they are involved. Instead, as Anne Sophie Maincke explains, if there are parts or substances, they must be “reconceptualised as stabilized higher-order processes that persist as long as stabilization can be maintained” (2018). Processes are ontologically primary. Recent literature in molecular biology on molecular pathways (cf. Boniolo and Campaner 2018; Brigandt 2018; Ioannides and Psillos 2017; Ross 2018) seems to be another instantiation of this shift from mechanistic to processual explanations. But Christopher Austin (2016) has recently challenged the idea that processual explanations can be sufficiently grounded “without the metaphysical underpinning of the very mechanisms which processes purport to replace” (639).
