Religious wars are not caused by the fact that there is more than one religion, but by the spirit of intolerance...the spread of which can only be regarded as the total eclipse of human reason.

Life was given to me as a favor, so I may abandon it when it is one no longer.

There are only two cases in which war is just: first, in order to resist the aggression of an enemy, and second, in order to help an ally who has been attacked.

Oh, how empty is praise when it reflects back to its origin!
