%0 Journal Article %T David LewisĄ¯s Neglected Challenge: ItĄ¯s Me or God %A Andrew Stephenson %J Perspectives : International Postgraduate Journal of Philosophy %D 2010 %I %X I begin by sketching a dialectic typical of modern discussions of the ontological argument and explain the underlying modal principles. I will not pursue this well-worn dialectic. Instead I will explicate David LewisĄ¯s valid reconstruction (in first order predicate logic) of St AnselmĄ¯s argument in Proslogion-II. LewisĄ¯s objections to this argument are based on his idiosyncratic views about modality. Implicitly, Lewis presents a challenge: either I am right about modality, or there is a sound version of the ontological argument. More specifically, Lewis claims there is no good reason to supposethere is anything special about the actual world. I suggest there is good reason to think that must be incorrect. Thus we are left with a formal version of the ontological argument for GodĄ¯s existence that for all we have seen here looks eminently viable. %K David Lewis %K Anselm %K modality %K modal logic %K ontological argument %K God %U http://www.ucd.ie/philosophy/perspectives/resources/issue3/Perspectives_volumeIII_DLewisNeglectedChallenge.pdf
