"I felt DeLeon understood Marx very well abstractly but knew little about the practical needs of the labor movement. The last time I talked with DeLeon I told him I was moving to Philadelphia and was willing to accept the secretaryship of the S.L.P. local there, which had been offered me, but that I could not go along with their principles wholeheartedly. As a good friend of mine, DeLeon accepted what I said without anger, but would not change his methods."
