Kanger was the son of a missionary couple and received his PhD in philosophy from Stockholm University in 1957 . 1963 to 1968 he was a professor at the Åbo Akademi and then in Uppsala. In 1968/69 he was visiting professor at the University of California.

He is known for contributions to modal logic and its applications in philosophy (e.g. legal philosophy), Possible Worlds of Semantics (the founder of which is usually considered to be Saul Kripke ), Logic of Action , proof theory and Deontic logic . Among other things, the Anderson-Kanger reduction is named after him and Alan Ross Anderson (after independent work by the two of them in the 1950s) and occasionally the Kanger-Lindahl theory (also after his student Lars Lindahl, who further developed it).

His wife Helle Kanger used his methods to analyze the Declaration of Human Rights in 1948.

In 1972 he became a Knight of the North Star Order .
