> He was a staunch follower of the pre-1914 Kautsky
This is correct. Not only that, but Lenin also took Kautsky's position *against* Rosa Luxemburg during the "mass strike" debate within the SPD.
I'd like to think that Lenin's support for soviet power in 1917 represents an implicit revision of his position vis-a-vis Luxemburg, but does anyone know of any actual texts where he revises his position in favor of Luxemburg and against Kautsky?
^^^^^^^ CB: You should probably take the emphatic criticism of Kautsky in _The State and Revolution_ ( "renegade" and "ex-Marxist") as a somewhat more explicit revision of his position vis-a-vis Luxemburg generally then, but more looking to now and forward than backward. Concrete analysis of the concrete situation doesn't involve much revisiting analyses of the past and revising them.
