24 Sometimes songs excite us, and quickened rhythm and the martial noise of trumpets; so, too, shocking pictures and the dreadful sight of tortures, however well deserved, affect our minds. Hence it is that we smile when others are smiling, that a crowd of mourners makes us sad, and that we take a glowing interest in another’s battles; all of which feelings are not anger, any more than that which clouds our brow at the sight of a stage shipwreck is sadness, or what we feel, when we read how Hannibal after Cannae beset the walls of Rome, can be called fear. All these are emotions of minds which are loath to be moved, and are not passions, but rudiments which may grow into passions. So, too, a soldier starts at the sound of a trumpet, although he may be dressed as a civilian and in the midst of a profound peace, and camp horses prick up their ears at the clash of arms. It is said that Alexander, when Xenophantus was singing, laid his hand upon his weapons.
