It is the duty of a man of honor to teach others the good which he has not been able to do himself because of the malignity of the times, that this good finally can be done by another more loved in heaven.
I hold it to be of great prudence for men to abstain from threats and insulting words towards any one, for neither the one nor the other in any way diminishes the strength of the enemy; but the one makes him more cautious, and the other increases his hatred of you, and makes him more persevering in his efforts to injure you
Thus it happens in matters of state; for knowing afar off (which it is only given a prudent man to do) the evils that are brewing, they are easily cured. But when, for want of such knowledge, they are allowed to grow so that everyone can recognize them, there is no longer any remedy to be found.
All courses of action are risky, so prudence is not in avoiding danger (it's impossible), but calculating risk and acting decisively. Make mistakes of ambition and not mistakes of sloth. Develop the strength to do bold things, not the strength to suffer.
I assert once again as a truth to which history as a whole bears witness that men may second their fortune, but cannot oppose it; that they may weave its warp, but cannot break it. Yet they should never give up, because there is always hope, though they know not the end and more towards it along roads which cross one another and as yet are unexplored; and since there is hope, they should not despair, no matter what fortune brings or in what travail they find themselves.
He who has annexed them, if he wishes to hold them, has only to bear in mind two considerations: the one, that the family of their former lord is extinguished; the other, that neither their laws nor their taxes are altered, so that in a very short time they will become entirely one body with the old principality.
For among other evils caused by being disarmed, it renders you contemptible; which is one of those disgraceful things which a prince must guard against.
Men seldom rise from low condition to high rank without employing either force or fraud, unless that rank should be attained either by gift or inheritance.
God and nature have thrown all human fortunes into the midst of mankind; and they are thus attainable rather by rapine than by industry, by wicked actions rather than by good. Hence it is that men feed upon each other, and those who cannot defend themselves must be worried.
