Searching for an early, highly theoretical, even philosophical, math paper on models or small-world networks

Stanley Milgram, The Small World Problem, Psychology Today 2, 60 (1967) seems to fit the bill: +50 years old, "kind of philosophical", and yes, iconic -- cited more than 9,000 times. There ...
