"Anarchism always "demands the impossible" even as it tries to also "realize the impossible." Its idealism is thoroughly pragmatic. Hierarchical forms of social organization can never fulfill most peoples' needs or desires, but time and again, nonhierarchical forms have demonstrated their capacity to come closer to that aim. It makes eminent and ethical sense to experiment with utopian notions. No other political philosophy does this as consistently and generously, as doggedly, and with as much overall honesty about the many dead-ends in the journey itself."
