Eratosthenes was the director of the great library of Alexandria, the Centre of science and learning in the ancient world. Aristotle had argued that humanity was divided into Greeks and everybody else, whom he called barbarians and that the Greeks should keep themselves racially pure. He thought it was fitting for the Greeks to enslave other peoples. But Erathosthenes criticized Aristotle for his blind chauvinism, he believed there was good and bad in every nation.

There is no such thing on earth as an uninteresting subject; the only thing that can exist is an uninterested person. Nothing is more keenly required than a defence of bores. When Byron divided humanity into the bores and bored, he omitted to notice that the higher qualities exist entirely in the bores, the lower qualities in the bored, among whom he counted himself. The bore, by his starry enthusiasm, his solemn happiness, may, in some sense, have proved himself poetical. The bored has certainly proved himself prosaic.
But we are living in a sceptical and, if I may use the phrase, a thought-tormented age: and sometimes I fear that this new generation, educated or hyper-educated as it is, will lack those qualities of humanity, of hospitality, of kindly humour which belonged to an older day.
As history has demonstrated many times over, change may arrive slowly or quickly but it is the one constant, in one form or another, on which we can all count.
