'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.
