Erasmus

--> You see that hitherto nothing has been achieved by treaties, nothing advanced by alliances, nothing by violence or revenge. Now try instead what conciliation and kindness can do. War springs from war, revenge brings further revenge. Now let generosity breed generosity, kind actions invite further kindness, and true royalty be measured by willingness to concede sovereignty.
