Tony Cliff on Rosa Luxemburg

“Franz Mehring, the biographer of Marx, did not exaggerate when he called Rosa Luxemburg the best brain after Marx. But she did not contribute her brain alone to the working-class movement; she gave everything she had — her heart, her passion, her strong will, her very life.”

“A passion for truth made Rosa Luxemburg recoil from any dogmatic thought. In a period when Stalinism has largely turned Marxism into a dogma, spreading desolation in the field of ideas, Rosa Luxemburg's writings are invigorating and life-giving. Nothing was more intolerable to her than bowing down to "infallible authorities". As a real disciple of Marx she was able to think and act independently of her master.”

“During a period when so many who consider themselves Marxists sap Marxism of its deep humanistic content, no one can do more to release us from the chains of lifeless mechanistic materialism than Rosa Luxemburg. For Marx communism (or socialism) was "real humanism", "a society in which the full and free development of every individual is the ruling principle".”
