Edward Gibbon Quote

Inclined to peace by his temper and situation, it was easy for [Augustus] to discover that Rome, in her present exalted situation, had much less to hope than to fear from the chance of arms; and that, in the prosecution of remote wars, the undertaking became every day more difficult, the event more doubtful, and the possession more precarious and less beneficial.
