'Women so empowered are dangerous' Written with a 'black woman's anger' and the precision of a poet, these searing pieces by the groundbreaking writer Audre Lorde are a celebration of female strength and solidarity, and a cry to speak out against those who seek to silence anyone they see as 'other'.One of twenty new books in the bestselling Penguin Great Ideas series. This new selection showcases a diverse list of thinkers who have helped shape our world today, from anarchists to stoics, feminists to prophets, satirists to Zen Buddhists.
