What are the motifs in The Man Without Qualities by Robert Musil?

Progress is one important concept found pervasively throughout the novel. The novel grows naturally out of the 19th century. In Germany, the modern and the idea of progress were often found together. German philosophy took the idea and raised it to the spiritual level. Although not everyone bought into this idea it was highly popular. If it were not for the belief in progress, which is intimately associated with improvement, there could not be any technological or scientific advancement. Not only that, but Diotima's Collateral Campaign relies on the idea of progress.
