Lassalle rejected the Marxist idea that the state was a class-based power structure destined to 'wither away.' Instead, he saw the state as an independent entity and an instrument of justice essential for achieving socialist goals . This fundamental disagreement put him at odds with Marx, who viewed Lassalle as a 'reformist heretic' .

Lassalle championed an evolutionary approach rather than a revolutionary one . He held that the German working class had to organize itself into a national association whose immediate goal would be direct, universal suffrage . He believed that gaining political power through the ballot box would allow the state to introduce socialist reforms .

Lassalle's concept of 'state socialism' provided a theoretical foundation for the reformist wing of the socialist movement. His ideas were a major influence on Eduard Bernstein's revisionism and helped the German Social Democratic Party adopt the aims of parliamentary democracy . His approach offered a practical, gradual path to socialism, in contrast to the revolutionary doctrines of his contemporaries .

Lassalle is remembered not as a profound theorist but as a pioneer and a founder of the German labor movement . His focus on the 'true aim on history's horizon: the liberation of man' and his emphasis on the power of the people's will set him apart from the more deterministic Marxism of his time, making him a key figure in the evolution of democratic socialism .
