From the last para:
Human civilisations learn from one another more than they realise, more than we realise. In a collection of essays published by Needham on the historic dialogue of East and West in 1969, he chose for his title Within the Four Seas. That title was from the Analects of Confucius, who said, "Within the Four Seas, all men are brothers”. In the heyday of Third World solidarity in the 50’s, the Indians had a saying ─ "Hindi-Chini, bhai bhai” ─ Indians and Chinese are brothers. In these confused times, we need to learn from one another on the basis of a deep respect for each other as human beings.
