We do not learn
We are doomed to repeat our mistakes for much longer to come. "New religions" spring up daily, new philosophies, new wisdom. What hope have we? - we who refuse to make a start in the beginning itself.
Praying for the dead
I pray for you, that your praying for the dead constitutes your learning from their mistakes, taking responsibility for their crimes, and doing what they never had the courage to do.
Let those fountains of grief, and waterfalls of pity go their own way - the way of the dead.
