Reason and Government
Man, having been made a rational creature, ought to do nothing except by reason; for, otherwise he acts against nature, and so against the Author of nature. Again, the greater a man is, and the higher his position, the more strictly is he bound to follow reason. It follows that if he is sovereignly rational, he is bound to make reason reign; that is to say, it is his duty to make all those who are under his authority revere and obey reason religiously. Love is the most potent motive for obedience; and it is impossible that subjects should not love their prince if they know that reason is the guide of all his actions.
Since reason should be the guide of princes, passion, which is of all things the most incompatible with reason, should be allowed no influence on their actions. Passion can only blind them; make them take the shadow for the substance; and win for them odium in the place of affection.
Government requires a masculine virtue and an immovable firmness; for softness exposes those in whom it is found to the machinations of their enemies. Though there have been notable exceptions, their softness and their passions have generally made women unfit for rule.
Public Interests First
The public advantage should be the single object of the king and his counsellors, or should at least be preferred to every private interest. It is impossible to estimate the good which a prince and his ministers may do if they religiously follow this principle, or to estimate the disasters which must fall upon the state whose public interests are ruled by private considerations. True philosophy, the Christian law, and the art of statesmanship, unite to teach this truth.
The prosperity which Spain has enjoyed for several centuries has been due to no other cause than that her council has consistently preferred the interests of the state to all others, and most of the calamities which have visited France have been due to the preference of private advantage.
It is easy for princes to consent to the general regulations of their state, because in making them they have only reason and justice before their eyes, and men willingly embrace reason and justice when there are no obstacles to turn them from the right path. But when occasions arise for putting these regulations into practice, we do not find that princes always show the same firmness, for then the interests of factions and of minorities are pressed upon them; pity, sympathy, favour, and importunities solicit them and oppose their just designs; and they have not always strength enough to conquer themselves and to despise these partial considerations, which ought to have no weight at all in the affairs of the commonwealth.
It is on these occasions that they must gather up all their strength against their weakness, and remember that God has placed them there to safeguard the public interest.
