page 368 note 2 Following Bunge, op. cit., pp. 121 ff., it is useful to distinguish conjunctive and disjunctive plurality or multiplicity of causes so that no confusion can arise. Conjunctive plurality, i.e. the fact that more than one condition must be satisfied conjointly in order that something can take place, is non-controversial while the matter is different in the case of disjunctive plurality, as I have shown above (where when I spoke of plurality the disjunctive kind was, of course, referred to).
page 370 note 1 Pap, op. cit., pp. 255–57, makes the same point although in different words. What I call ‘relatively necessary condition’ he referes to as ‘conditionally necessary’ or ‘contributing condition’. See also Nagel, Ernest, The Structure of Science, New York, 1962 pp. 559–60Google Scholar, who speaks of ‘contingently necessary conditions’.
page 370 note 2 I do not deny, of course, that the customary definition of some words includes part of the cause, e.g. in the case of ‘rust’ the definition of which in the Concise Oxford Dictionary includes ‘formed on iron or steel by oxidation esp. as effect of moisture’. But this does not affect the point made here, namely that for purposes of causal analysis we cannot include causal features in the definition of the effect.
