Niccolò Machiavelli,
The Annotated Prince — Chapter XVI: Of Liberality and Miserliness
(1513)
“ Because for a Prince who leads his armies in person and maintains them by plunder, pillage, and forced contributions, dealing as he does with the property of others this liberality is necessary, since otherwise he would not be followed by his soldiers. Of what does not belong to you or to your subjects you should, therefore, be a lavish giver, as were Cyrus, Cæsar, and Alexander; for to be liberal with the property of others does not take from your reputation, but adds to it. What injures you is to give away what is your own. And there is no quality so self-destructive as liberality ”
