Of course, he was right. Why does it seem to be so highly prized by anarchists.
Anarchists aim to achieve maximum personal freedom for everyone.
We see liberty and freedom as absolutely essential to any form of socialism. Without freedom there is no growth, no creativity, no dignity - a revolution without freedom is simply a change of rulers. To be dominated is to be oppressed and denied the chance and the time to think. Domination stifles individuality and initiative and leads inevitably to conformity, mediocrity and misery. You only have to look to the former Stalinist countries to see how a revolution without freedom at it's core would disintegrate.
