From George Washington’s Farewell Address:

(Faction = partisanship/political parties)

“The very idea of the power and the right of the people to establish government presupposes the duty of every individual to obey the established government. All obstructions to the execution of the laws, all combinations and associations under whatever plausible character, with the real design to direct, control, counteract, or awe the regular deliberation and action of the constituted authorities, are destructive of this fundamental principle and of fatal tendency.

They serve to organize faction, to give it an artificial and extraordinary force—to put in the place of the delegated will of the nation the will of a party; often a small but artful and enterprising minority of the community; and, according to the alternate triumphs of different parties, to make the public administration the mirror of the ill concerted and incongruous projects of faction, rather than the organ of consistent and wholesome plans digested by common councils and modified by mutual interests.

However combinations or associations of the above description may now and then answer popular ends, they are likely, in the course of time and things, to become potent engines by which cunning, ambitious, and unprincipled men will be enabled to subvert the power of the people and to usurp for themselves the reins of government, destroying afterwards the very engines which have lifted them to unjust dominion…

The alternate domination of one faction over another, sharpened by the spirit of revenge natural to party dissension, which in different ages and countries has perpetrated the most horrid enormities, is itself a frightful despotism. But this leads at length to a more formal and permanent despotism. The disorders and miseries which result gradually incline the minds of men to seek security and repose in the absolute power of an individual; and sooner or later the chief of some prevailing faction, more able or more fortunate than his competitors, turns this disposition to the purposes of his own elevation on the ruins of public liberty.

Without looking forward to an extremity of this kind (which nevertheless ought not to be entirely out of sight) the common and continual mischiefs of the spirit of party are sufficient to make it the interest and the duty of a wise people to discourage and restrain it.”
