Cumulation, Efficient Cause, Proximate Cause

Kant joins Aristotle and Hume in treating an Efficient Cause as an event isolated from its context, thus abstracting it from other conditions that contribute to the production of an Effect. For example, that the striking of a match 'causes' it to ignite presupposes dryness, sufficient oxygen, adequate striking force, etc. Likewise, 'Efficient Cause' seems to questionably classify 'the straw that breaks the camel's back', and to be problematically applicable to chemical reactions in which no single component is the decisive one. In other words, 'Efficient Causality', as understood by each of the three, is a special case of a cumulative process, in which the penultimate phase is emphasized. Hence, a less misleading characterization of that penultimate phase might be 'Proximate', instead of 'Efficient', 'Cause'.
