In my investigation into the Seridei Aish's description of the Mussar Movement as "frum haskala", I have come back to my original understanding. At this point I disagree with Prof. Shapiro that "frum haskala" simply meant concern with spiritual development and fear of G-d.
The Haskala was a man based vision -
not a religious one. I just posted the Seridei Ish's vision of
the Jew in the ghetto - not only was it repressive economically
and psychologically but most found religion also to be repressive.

Mussar was clearly a man based program to revive religion as was Hirsch's Torah im Derech Eretz. It also involved participation in the world, tikun olam and an awareness of human knowledge and a focus on the individual human being. This is clearly the opposite of Chassidus which is a movement based on ruach hakodesh, revelation and Daas Torah and subjugation to authority. The Mussar Movement was also opposed to the ghetto - either of the body or mind and deprivation of wordly pleasures and experience.
