In my metaphysics class, I am asked to first, explain how, on Lewis’s view, the following sentence is true:
(a) Obama is contingently the president of the US
and second, present the objection that Lewis’s account fails to adequately account for the truth of (a) because his account doesn’t sufficiently focus on Obama.
I am having trouble understanding Lewis's view when it comes to the truth of the sentence.
Contingently means that it happened by chance. He did not become president by chance because he was voted into position by the majority of the public. However, the vice-president that becomes president because the current president was removed for some reason could be considered the contingent president.
