I want to know the answer to the following question:
What has been maintained by the Greeks throughout their extended history ?
All the background I'm provided with is that "Paideia was one of the highest societal values in the Greek and Hellenistic world while the first European institution described as a university was founded in 5th century Constantinople and operated in various incarnations until the city's fall to the Ottomans in 1453.". Is that enough to answer the question?
Answer: no
