 Lange had an indirect impact on what was later known as the revisionist debate within socialism. Eduard Bernstein, the father of revisionism, eventually broke with Marxian orthodoxy, and argued that achieving socialism did not require a revolution, or at least that much could be achieved by working within existing democratic political structures. This was in part a result of Bernstein’s developing neo-Kantianism (Steger 1992). He claimed that it was primarily Lange’s work that led him to both Kant and revisionism (Vorländer 1900, 47; Bernstein 1892). He suggests that when it comes to articulating a path forward for socialism, “I would translate ‘back to Kant’ by ‘back to Lange’” (Bernstein 1902, 187–88).
