 Mechanistic explanation is non-causal, and so is reductive explanation. However, sometimes, reductionist models are phrased in causal terminology. Enç (1976) is a case in point. He describes reductive explanation and reductive dependence as causal. The description he gives of this relation, however, does not fit the usual use of the term ‘causation’. Enç describes it as a ‘generative’ relation that may hold between an object a and an object b even if a=b. Hence, despite the fact that he uses the term ‘causation’, he should not be interpreted as stating that literally, reductive explanation is causal explanation. This has been overlooked by Schaffner (1993) who reflects upon Enç’s description, criticizing him for assuming that reduction is causation.
