I outline some objections to Lewis’s (1976) theory of abilities. I then discuss the threat of Logical Fatalism. I criticise Van Cleve’s riposte to Lewis’s paper and highlight a curious argument of Lewis’s. I end by commenting on Lewis’s solution to the Grandfather Paradox and matters arising.

David Lewis; time travel; abilities; fatalism; Grandfather Paradox.
