In an age of rising inequality and social fracture, Political Philosophy as if the Neighbour Mattered reimagines governance around one timeless principle — love thy neighbour as thyself. This framework transforms moral empathy into measurable public policy, proposing a “Loving Republic” where care becomes infrastructure, justice is restorative, and every law passes the “neighbour impact” test. Drawing from thinkers across civilizations — from Bhishma and Confucius to Rawls, Gandhi, and Habermas — it offers a practical constitutional model for inclusive, ecological, and compassionate governance that treats the good society not as an abstraction, but as a shared moral practice.
