Collected writings by one of the most influential Black Brazilian feminist intellectuals of the twentieth century Beatriz Nascimento (1942-1995) was a poet, historian, artist, and political leader in Brazil's Black movement, an innovative and creative thinker whose work offers a radical reimagining of gender, space, politics, and spirituality around the Atlantic and across the Black diaspora. Her powerful voice still resonates today, reflecting a deep commitment to political organizing, revisionist historiography, and the lived experience of Black women. The Dialectic Is in the Sea is the first English language collection of writings by this vitally important figure in the global tradition of Black radical thought. The Dialectic Is in the Sea traces the development of Nascimento's thought across the decades of her activism and writing, covering topics such as the Black woman, race and Brazilian society, Black freedom, and Black aesthetics and spirituality. Incisive introductory and analytical essays provide key insights into the political and historical context of Nascimento's work. This engaging collection includes an essay by Bethânia Gomes, Nascimento's only daughter, who shares illuminating and uniquely personal insights into her mother's life and career.
