There is no other man who has influenced life for all times. There is no other man who is a perfect role model for all humans for all times. There is no other man who has given rights to people of every society for all times.
So who is it then?

Einstein, Darwin, Marx, Socrates, Newton, Plato, Freud… (who?).
OK, is it Jesus, Moses, Napoleon, Julius Caesar, Gandhi, Buddha, Lenin, Mussolini, Stalin, Churchill, Martin Luther King, Shakespeare, Princess Diana or Abraham Lincoln? Or even (God forbid) Ali G, Tu Pac, Michael Jackson or David Beckam?
