«The study of human conduct» sounds overly broad, but googling 'round the web, one gets a pretty good idea of what is (and who are) involved here. This
site is not a bad place to start ; another promising
entrance to this recondite world is that of Roderick T Long, who has even written an a longish (70 pages)
article in which he claims the early Confucians as
Gesinnungsgenossen ! Not really my cup of tea, but fun to read - thanks for the tip,
Apo !...
