I was scared in recent days.I'm more and more realizing the ignorance of myself to the world.
There is another saying jumping out when the old saying "the earth goes round the sun"has been deeply into my heart. "why the sun,come on, you out , now the earth around the man" " what? if the man can turn day to night or he can give us the energy which we need ?" Surely he can . sometimes, we like white which is the symbol of hope or pure,hence,man discover the black to pollute it,then the day turns to night.However, another kind of man can't live in the night forever,so they get together whose action creat the energy origins from themself to fight against the black,the more people joining into the group ,the more energy will be collected until the balance to the white again.So , man bring the day again.
That's human theory,yeah, human,it's all of us ,but the single one of us.Consequently,in front of the history,the time,the great man,even the peer,we will be always ingnorant,just like the Socrates saying "My life, I only know one thing,why I was so ignorant."
