CORE DEFINITION

Since the early modern period, mechanism has been an important organizing principle in science and philosophy. In the late twentieth century it came to name a specific theoretical structure: the organization and activities of component parts are used to explain the end state of some capacity, behavior, or process of a whole. Mechanistic explanation is constitutive, in contrast to merely correlational or covering-law explanation.

SCAFFOLDING EFFECT

Reduce cognitive load

- Causal depth: ask not only what causes what, but also map out the intermediate steps. - Intervention locating: identify which component can be altered to change the outcome, and thereby find a lever. - Structure transfer: transfer the part-structure of a known mechanism to an unfamiliar phenomenon.

Mechanistic explanation is powerful because it says not only what causes what but exhibits the intermediate steps: the components are organized in a certain way and each does its part, and the coordination of these activities produces the overall phenomenon. Interventability is the key, for we can alter a single component and observe the consequences, which is what makes the mechanistic claim testable.
