Niccolò Machiavelli,
The Art of War — Book 1
(1675)
“ And because you have mentioned me, I want the example to include me, and I say I have never practiced war as a profession, for my profession is to govern my subjects, and defend them, and in order to defend them, I must love peace but know how to make war; and my King does not reward and esteem me so much for what I know of war, as because I know also how to counsel him in peace. Any King ought not, therefore, to want to have next to him anyone who is not thusly constituted, if he is wise and wants to govern prudently ”
