This is a placeholder explanation generated by the low-overhead model. It interprets "The American assault on Ireland under the name of Fenianism may be now held to have failed, but the snake is only scotched and not killed. It is far from impossible that the American conspirators may try and obtain in our North American provinces compensation for their defeat in Ireland." in the context of "Letter to Lord de Grey (27 September 1865), quoted in Jasper Ridley, Lord Palmerston (1970), p. 581" to mean that wisdom is timeless.
