Mr Ollivander: "He Who Must Not Be Named did great things. Terrible, yes, but great." (From the movie: Harry Potter and the Philosopher's Stone, based on J. K. Rowling's novel of the same name.).Even when humanity arrives at a higher development, there is yet a higher development to achieve. Great things are great developments, great powers both of which can be misused. Hagrid tells Harry that there are "bad wizards" in the world, and the Sorting Hat tells Harry that the Slytherines can help Harry attain greatness. "Bad" witches and wizards are left behind and humanity moves on to new and better things, "great" things. In fact as humanity progresses, these great things become more common (communistic), more likely to come from our neighbors and in fact ourselves, from the majority. According to scientific communism we are in the period of people's republics in which majority populations around the world build socialism by winning control of state power. In scientific communism: when we arrive at a new level of development which negates the old, we then turn around and negate this negation and move on to something better, something greater.
