It requires a very unusual mind to undertake the analysis of the obvious. - Alfred North Whitehead

As soon as high consciousness is reached, the enjoyment of existence is entwined with pain, frustration, loss, tragedy. Amid the passing of so much beauty, so much heroism, so much daring, Peace is then the intuition of permanence. It keeps vivid the sensitiveness to the tragedy; and it sees the fineness beyond the faded level of surrounding fact. Each tragedy is the disclosure of an ideal: What might have been, and was not; What can be. The tragedy was not in vain.
