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.
All true religion, all true morality, all true mysticism have but one object, and that is to act on humanity, collective and individual, in such a manner that it shall correspond efficiently with the great law of development, and co-operate consciously therewith to achieve the end of development.
If we want to discover the full potential in our humanity, we need to celebrate those heartbreaking strengths and those glorious disabilities that we all have...it is our humanity, and all the potential within it that makes us beautiful.
We live within the environment. So that directly relates with our survival, our life. So through that way, more concern of well being of humanity, then naturally concerned about environment.
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.
If humanity is to survive, happiness and inner balance are crucial. Otherwise the lives of our children and their children are more likely to be unhappy, desperate and short. Material development certainly contributes to happiness - to some extent - and a comfortable way of life. But this is not sufficient. To achieve a deeper level of happiness we cannot neglect our inner development.
