Michael Scriven on Relevance - Dictionary of Arguments

Fraassen I 104
Relevance/explanation/ScrivenVsHempel/BrombergerVsHempel: Relevance provides neither sufficient nor necessary conditions that something is an explanation.
Not sufficient: good belief reasons are no explanation: e.g. redshift cannot be a reason for the expansion.
Not necessary: not every explanation gives good belief reasons. - E.g. rare disease as a result of a frequent disease: - So you advise for treatment. - but it would not be rational to expect that the disease occurs.
E.g. a very small amount of uranium does probably not radiate - but when it radiates the correct explanation is, that it is uranium.
E.g. a man that takes birth control pills and does not get pregnant.
I 109
Relevance is not sufficient: E.g. 90% of the plants are killed: then it is not an explanation for the plants that survived that they were sprayed.
