Activist

Rudolf Eucken had a beard and a way of tucking the ends of his bow tie under his collar that I remember Macmillan using in the 1970s. But it was in 1908, a year after Kipling, that Eucken won the Nobel prize for literature. (Anyone read a book by him?) His belief was that truth is arrived at through active striving after the spiritual life, and he called this principle activism.
