Albert Einstein (1879 - 1955), the great German physicist, was also a very wise man. Today I found a quote that made me shiver (rough translation by me)
"I am not sure with which weapons World War III will be fought, but World War IV will be fought with stones and sticks".
He also said:
"Two things are infinite (endless), the universe and human stupidity, but about the universe I am still not quite sure."
To cheer us up he said:
"A clever person solves a problem. A sage man avoids it."
Suitable to your convictions please hope or pray for that!
