History repeats itself in the large because human nature changes with geological leisureliness.
Will DurantWhat if it is for life's sake that we must die? In truth we are not individuals; and it is because we think ourselves such that death seems unforgivable. We are temporary organs of the race, cells in the body of life; we die and drop away that life may remain young and strong. If we were to live forever, growth would be stifled, and youth would find no room on earth. Death, like style, is the removal of rubbish, the circumcision of the superfluous. In the midst of death life renews itself immortally.
Will DurantThe time when you need to do something is when no one else is willing to do it, when people are saying it can't be done.
