The world Trotskyist movement was built from its inception in incessant struggle not only against revisionists and centrists but also against sectarians. Especially illuminating in this connection are a series of letters written by Leon Trotsky in 1929-30 in an attempt to find, within the framework of a single organization, a common ground for collaborating with the Italian revolutionist Bordiga and his group. The attempt failed. – Editor
