Engels argued that the traditional monogamous household was in fact a recent construct, closely bound up with capitalist societies. Under this patriarchal system, women were servants and, effectively, prostitutes. Only Communism would herald the dawn of communal living and a new sexual freedom and, in turn, the role of the state would become superfluous.","forthcoming":false,"isbn13":"9780141191119","publication_date":"20100629","publisher":"Penguin Publishing Group","slug":"the-origin-of-the-family-private-property-and-the-state","subtitle":"","title":"The Origin of the Family, Private Property and the State"},"discovery":{"categories":{"all":[{"bisac_code":"POL042010","confidence_band":"low","label":"Anarchism","score":0.6497,"source":"bisac_hint_model"},{"bisac_code":"SOC026040","confidence_band":"low","label":"Social Theory","score":0.6444,"source":"bisac_hint_model"},{"bisac_code":"POL042060","confidence_band":"low","label":"Capitalism & Markets","score":0.6396,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"POL042010","confidence_band":"low","label":"Anarchism","score":0.6497,"source":"bisac_hint_model"},{"bisac_code":"SOC026040","confidence_band":"low","label":"Social Theory","score":0.6444,"source":"bisac_hint_model"},{"bisac_code":"POL042060","confidence_band":"low","label":"Capitalism & Markets","score":0.6396,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"HIS037060","confidence_band":"high","label":"19th-Century History","score":1,"source":"onix_publisher_code"},{"bisac_code":"PHI019000","confidence_band":"high","label":"Political Philosophy","score":1,"source":"onix_publisher_code"},{"bisac_code":"POL005000","confidence_band":"high","label":"Communism & Socialism","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Anarchism","score":0.6497,"slug":"anarchism"},{"label":"Social Theory","score":0.6444,"slug":"social-theory"},{"label":"Capitalism & Markets","score":0.6396,"slug":"capitalism-markets"}],"reader_fit":["Good for readers who enjoy Anarchism","Good for readers interested in philosophy","Good for fans of Politics"],"related_lists":[{"intro":"","slug":"shelf-soc026040-social-theory","title":"Social Theory Books","url":"https://bookfrontier.com/lists/shelf-soc026040-social-theory"}],"series":null,"similar_books":[{"authors":["Ruth Kinna"],"book_id":"9780141984667","cover_image_url":"https://img.bookfrontier.com/9780141984667.jpg?v=20260417T232332Z%3A2026-04-17T23%3A23%3A32Z","score":19.4525,"title":"The Government of No One","url":"https://bookfrontier.com/books/9780141984667"},{"authors":["Fara Dabhoiwala"],"book_id":"9780674987319","cover_image_url":"https://img.bookfrontier.com/9780674987319.jpg?v=20260417T232332Z%3A2026-04-17T23%3A23%3A32Z","score":18.5171,"title":"What Is Free Speech?","url":"https://bookfrontier.com/books/9780674987319"},{"authors":["Peter Kropotkin","David Priestland","Pyotr Kropotkin"],"book_id":"9780141396118","cover_image_url":"https://img.bookfrontier.com/9780141396118.jpg?v=20260417T232332Z%3A2026-04-17T23%3A23%3A32Z","score":17.0389,"title":"The Conquest of Bread","url":"https://bookfrontier.com/books/9780141396118"}],"topics":[{"evidence_refs":["keyword:world history"],"label":"History","score":0.9238,"slug":"history"},{"evidence_refs":["keyword:political science"],"label":"Science","score":0.2945,"slug":"science"},{"evidence_refs":["keyword:world history"],"label":"World","score":0.2022,"slug":"world"},{"evidence_refs":["keyword:political science"],"label":"Political","score":0.1549,"slug":"political"},{"evidence_refs":["keyword:philosophy"],"label":"Philosophy","score":0.1142,"slug":"philosophy"}],"what_you_get":["Themes: History, Science, Political.","Reading lane: Anarchism and Social Theory.","Publisher: Penguin Publishing Group."]},"llm_signals":null,"source_presence":{"amazon":true,"book_detail":true,"goodreads":true,"llm_signals":false,"similarity_seed":true},"stats":{"amazon_ratings_count":0,"goodreads_ratings_count":8116,"goodreads_reviews_count":697,"quality_score":0.944}}
