Niccolò Machiavelli,
The Prince (Hill Thomson) — Chapter III: Of Mixed Princedoms
(1910)
“ For the distempers of a State being discovered while yet inchoate, which can only be done by a sagacious ruler, may easily be dealt with; but when, from not being observed, they are suffered to grow until they are obvious to every one, there is no longer any remedy. The Romans, therefore, foreseeing evils while they were yet far off, always provided against them, and never suffered them to take their course for the sake of avoiding war; since they knew that war is not so to be avoided, but is only postponed to the advantage of the other side. ”
