Although an intelligent person and dedicated revolutionary socialist thinker, Jogiches was virtually incapable of converting his ideas into written words: "the mere thought of putting his ideas on paper paralyzes him," Luxemburg later recalled.
Consequently, the chief contribution of Jogiches was that of literary stimulant to the skilled publicist Luxemburg as well as behind-the-scenes organizer of the fledgling underground political party that he had helped to establish.

As Luxemburg grew in fame as a Marxist theoretician, Jogiches became gradually more embittered about his life, until by his mid-30s, he had come, as one Luxemburg biographer phrased it, to have "fully realized the gap between his youthful aspirations and the disillusionments of reality."

Interpersonal conflict followed, exacerbated by the different trajectories of personal achievement, with the pair permanently separating in 1907.
