A Prince is likewise esteemed who is a stanch friend and a thorough foe, that is to say, who without reserve openly declares for one against another,… - Niccolò Machiavelli

A prince is also esteemed when he is a true friend and a true enemy.

A prince is also esteemed when he shows himself a true friend or a true enemy, that is, when, without reservation, he takes his stand with one side or the other. This is always wiser than trying to be neutral, for if two powerful neighbors of yours fall out they are either of such sort that the victor may give you reason to fear him or they are not. In either case it will be better for you to take sides and wage an honest war.

And let it be noted that there is no more delicate matter to take in hand, nor more dangerous to conduct, nor more doubtful in its success, than to set up as a leader in the introduction of changes.

If you only notice human proceedings, you may observe that all who attain great power and riches, make use of either force or fraud; and what they have acquired either by deceit or violence, in order to conceal the disgraceful methods of attainment, they endeavor to sanctify with the false title of honest gains. Those who either from imprudence or want of sagacity avoid doing so, are always overwhelmed with servitude and poverty; for faithful servants are always servants, and honest men are always poor; nor do any ever escape from servitude but the bold and faithless, or from poverty, but the rapacious and fraudulent. 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.

When evening has come, I return to my house and go into my study. At the door I take off my clothes of the day, covered with mud and mire, and I put on my regal and courtly garments; and decently reclothed, I enter the ancient courts of ancient men, where, received by them lovingly, I feed on the food that alone is mine and that I was born for. There I am not ashamed to speak with them and to ask them the reason for their actions; and they in their humanity reply to me. And for the space of four hours I feel no boredom, I forget every pain, I do not fear poverty, death does not frighten me. I deliver myself entirely to them.
