{"product_id":"proof-against-itself","title":"Proof Against Itself","description":"Paradox is a guided tour of puzzles that have shaped logic, science, economics, mathematics, and philosophy?told in verse and unpacked in prose. Each paradox is introduced as a formally rhymed poem, followed by a concise explanation that makes the underlying idea clear without sacrificing rigor. Along the way, readers encounter liars and barbers, time-travelers and twins, markets that fail because they work too well, infinities that misbehave, and arguments that collapse under their own logic. Some paradoxes are resolved; others are not. All are illuminating.","brand":"Gardners","offers":[{"title":"Default Title","offer_id":57507764076917,"sku":"9781806950768","price":17.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/7193\/3106\/files\/9781806950768.jpg?v=1787042904","url":"https:\/\/backstory.london\/products\/proof-against-itself","provider":"Backstory","version":"1.0","type":"link"}
