If a man, before he passed from one stage to another, could know his future life in full detail, he would have nothing to live for. It is the same with the life of humanity. If it had a programme of the life which awaited it before entering a new stage, it would be the surest sign that it was not living, nor advancing, but simply rotating in the same place.
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.
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.
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.
There's something about when humanity goes from hoping they get lucky in finding something fermented to doing it on purpose. They don't understand what they've done until the late 1800s, but they know if they combine things in a certain way, they'll get something magic.
The sole meaning of life is to serve humanity by contributing to the establishment of the kingdom of God, which can only be done by the recognition and profession of the truth by every man.
All of us living in today's world are facing an enormous crisis - arguably the greatest that humanity has ever faced - in the form of man-made global warming; one can't be neutral at such a moment. It's like claiming to be neutral if you're living in Germany in 1933.
Forgiveness is the most effective way of dealing with arguments; altruism and forgiveness bring humanity together so that no conflict, however serious, will go beyond the bounds of what is truly human.
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.
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.
