It is a miserable state of mind, to have few things to desire, and many things to fear; and yet that commonly is the case of kings; who, being at the highest, want matter of desire, which makes their minds more languishing; and have many representations of perils and shadows, which makes their minds the less clear. And this is one reason also, of that effect which the Scripture speaketh of, That the king’s heart is inscrutable. For multitude of jealousies, and lack of some predominant desire, that should marshal and put in order all the rest, maketh any man’s heart, hard to find or sound. Hence it comes likewise, that princes many times make themselves desires, and set their hearts upon toys; sometimes upon a building; sometimes upon erecting of an order; sometimes upon the advancing of a person; sometimes upon obtaining excellency in some art, or feat of the hand; as Nero for playing on the harp, Domitian for certainty of the hand with the arrow, Commodus for playing at fence, Caracalla for driving chariots, and the like. This seemeth incredible, unto those that know not the principle, that the mind of man, is more cheered and refreshed by profiting in small things, than by standing at a stay, in great. We see also that kings that have been fortunate conquerors, in their first years, it being not possible for them to go forward infinitely, but that they must have some check, or arrest in their fortunes, turn in their latter years to be superstitious, and melancholy; as did Alexander the Great; Diocletian; and in our memory, Charles the Fifth; and others: for he that is used to go forward, and findeth a stop, falleth out of his own favor, and is not the thing he was.

To speak now of the true temper of empire, it is a thing rare and hard to keep; for both temper, and distemper, consist of contraries. But it is one thing, to mingle contraries, another to interchange them. The answer of Apollonius to Vespasian, is full of excellent instruction. Vespasian asked him, What was Nero’s overthrow? He answered, Nero could touch and tune the harp well; but in government, sometimes he used to wind the pins too high, sometimes to let them down too low. And certain it is, that nothing destroyeth authority so much, as the unequal and untimely interchange of power pressed too far, and relaxed too much.

This is true, that the wisdom of all these latter times, in princes’ affairs, is rather fine deliveries, and shiftings of dangers and mischiefs, when they are near, than solid and grounded courses to keep them aloof. But this is but to try masteries with fortune. And let men beware, how they neglect and suffer matter of trouble to be prepared for no man can forbid the spark, nor tell whence it may come. The difficulties in princes’ business are many and great; but the greatest difficulty, is often in their own mind. For it is common with princes (saith Tacitus) to will contradictories, Sunt plerumque regum voluntates vehementes, et inter se contrariae. For it is the solecism of power, to think to command the end, and yet not to endure the mean.

Kings have to deal with their neighbors, their wives, their children, their prelates or clergy, their nobles, their second-nobles or gentlemen, their merchants, their commons, and their men of war; and from all these arise dangers, if care and circumspection be not used.

First for their neighbors; there can no general rule be given (for occasions are so variable), save one, which ever holdeth, which is, that princes do keep due sentinel, that none of their neighbors do ever grow so (by increase of territory, by embracing of trade, by approaches, or the like), as they become more able to annoy them, than they were. And this is generally the work of standing counsels, to foresee and to hinder it. During that triumvirate of kings, King Henry the Eighth of England, Francis the First King of France, and Charles the Fifth Emperor, there was such a watch kept, that none of the three could win a palm of ground, but the other two would straightways balance it, either by confederation, or, if need were, by a war; and would not in any wise take up peace at interest. And the like was done by that league (which Guicciardini saith was the security of Italy) made between Ferdinando King of Naples, Lorenzius Medici, and Ludovicus Sforza, potentates, the one of Florence, the other of Milan. Neither is the opinion of some of the Schoolmen, to be received, that a war cannot justly be made, but upon a ............
