Among the numerous advantages promised by a well-constructed union, none deserves to be more accurately developed than its tendency to break and control the violence of faction. The friend of popular governments never finds himself so much alarmed for their character and fate as when he
contemplates their propensity to this dangerous vice. He will not fail, therefore, to set a due value on any plan, which, without violating the principles to which he is attached, provides a proper cure for it. The instability, injustice, and confusion introduced into the public councils have, in truth, been the diseases under which popular governments have everywhere perished... Complaints are everywhere heard from our most considerate and virtuous citizens, equally friends of public and private faith and of public and personal liberty, that our governments are too unstable, that the public good is disregarded in the conflicts of rival parties, and that measures are too often decided, not according to the rules of justice and the rights of the minor party, but by the superior force of an interested and overbearing majority... [I]t will be found... that prevailing and increasing distrust of our public engagements and alarm for private rights are echoed from one end of the continent to the other. These must be chiefly, if not wholly, effects of the unsteadiness and injustice with which a factious spirit has tainted our public administration...

As long as the reason of man continues to be fallible, and he is at liberty to exercise it, different opinions will be formed. As long as the connection subsists between his reason and his self-love, his opinions and his passions will have  a reciprocal influence on each other; and the former will be objects to which the latter will attach themselves. The diversity in the faculties of men, from which the rights of property originate, is not less an insuperable obstacle to a uniformity of interests. The protection of these faculties is the first object of government. From the protection of different and unequal faculties of acquiring property, the possession of different degrees and kinds of property immediately results; and from the influence of these on the sentiments and views of the respective proprietors ensues a division of society into different interests and parties.

The latent causes of faction are thus sown into the nature of man; and we see them everywhere brought into different degrees of activity, according to the different circumstances of civil society. A zeal for different opinions concerning religion, concerning government, and many other points... an attachment to different leaders ambitiously contending for pre-eminence and power; or to persons of other descriptions whose fortunes have been interesting to the human passions, have, in turn, divided mankind into parties, inflamed them with mutual animosity, and rendered them much more disposed to vex and oppress each other than to co-operate for the common good. So strong is this propensity of mankind to fall into mutual animosities that... most frivolous and fanciful distinctions have been sufficient to kindle their unfriendly passions and excite their most violent conflicts. But the most common and durable source of factions has been the verious and unequal distribution of property. Those who hold and those who are without property have ever formed distinct interests in society. Those who are creditors, and those who are debtors, fall under a like discrimination. A landed interest, a manufacturing interest, a mercantile interest, a moneyed interest, with many lesser interests, grow up of necessity in civilized nations, and divided them into different classes, actuated by different sentiments and views. The regulation of these various and interfering interests forms the principal task of modern legislation and involves the spirit of party and faction in the necessary and ordinary operations of government.

No man is allowed to be a judge in his own cause, because his interest would certainly bias his judgment, and, not improbably, corrupt his integrity.  With greater reason, a body of men are unfit to be both judges and parties at the same time; yet, what are many of the most important acts of legislation but so many judicial determinations, not indeed concerning the rights of single persons, but concerning the rights of large bodies of citizens? And what are the different classes of legislators but advocates and parties to the causes which they determine? Is a law proposed concerning private debts? It is a question to which creditors are parties on one side and debtors on the other. Justice ought to hold the balance between them. Yet the parties are, and must be, themselves the judges; and the most numerous party, or in other words, the most powerful faction, must be expected to prevail...

When a majority is included in a faction... the form of popular government enables it to sacrifice to its ruling passions or interest both the public good and private rights of other citizens. To secure the public good and the private rights against the danger of such a faction, and at the same time to preserve the spirit and the form of popular government, is then the great object to which our inquiries are directed...

By what means is this object attainable? Either the existent of the same passion or interest in a majority at the same time must be prevented, or the majority, having such coexistent passion or interest, must be rendered, by their number and local situation, unable to concert and carry into effect schemes of oppression...

From this view of the subject it may be concluded that a pure democracy, by which I mean a society consisting of a small number of citizens, who assemble and administer the government in person, can admit of no cure for the mischiefs of faction. A common passion or interest will, in almost every case, be felt by the majority of the whole; a communication and concert results from the form of government itself, and there is nothing to check the inducements to sacrifice the weaker party... Hence it is that such democracies have ever been spectacles of turbulence and contention; have ever been found incompatible with personal security or the rights of property; and have been in general a short in their lives as they have been violent in their deaths...

A republic, by which I mean a government in which the scheme of representation takes place, opens a different prospect and promises the cure for which we are seeking...

The two great points of difference between a democracy and a republic are: first, the delegation of the government in the latter to a small number of citizens elected by the rest; secondly, the greater number of citizens and greater sphere of country over which the latter may be extended.

The effect of the first difference is, on the one hand, to refine and enlarge the public views by passing them through the medium of a chosen body of citizens, whose wisdom may best discern the true interest of their country and whose patriotism and love of justice will be least likely to sacrifice it to temporary or partial considerations. Under such a regulation it may well happen that the public voice, pronounced by the representatives of the people, will be more consonant to the public good than if pronounced by the people themselves... The question resulting is, whether small or extensive republics are most favorable to the election of proper guardians of the public weal; it is clearly decided in favor of the latter...

...[A]s each representative will be chosen by a greater number of citizens in the large than in the small republic, it will be more difficult for unworthy candidates to practise with success...

It must be confessed that... [b]y enlarging too much the number of electors, you render the representative too little acquainted with the all their local circumstances and lesser interests; by reducing it too much, you render him unduly attached to these, and too little fit to comprehend and pursue great and national objects. The federal Constitution forms a happy combination in this respect; the great and aggregate interests being referred to the national, the local and particular to the State legislatures.

The other point of difference is the greater number of citizens and extent of territory which may be brought within the compass of republican than of democratic government; and it is this circumstance which renders factious combinations to be less dreaded in the former than in the latter. The smaller the society, the fewer probably will be the distinct parties and interests composing it; the fewer the distinct parties and interests, the more frequently will a majority be found of the same party; and the smaller number of individuals composing a majority, and the smaller the compass within which they are placed, the more easily will they concert and execute their plans of oppression. Extend the sphere and you take in a greater variety of parties and interests; you make it less probable that a majority of the whole will have a common motive to invade the rights of the other citizens; or, if such a common motive exists, it will be more difficult for all who feel it to discover their own strength and act in unison with each other...

The influence of factious leaders may kindle a flame within their particular States but will be unable to spread a general conflagration through the other States. A religious sect may degenerate into a political faction in a part of the Confederacy; but the variety of sects dispersed over the entire face of it must secure the national councils against any danger from that source. A rage of paper money, for an abolition of debts, for an equal division of property, or any other improper or wicked project, will be less apt to pervade the whole body of the Union than a particular member of it, in the same proportion that such a malady is more likely to taint a particular county or district than an entire State...

[T]herefore, we behold a republican remedy for the diseases most incident to republican government. And according to this degree of pleasure and pride we feel in being republicans ought to be our zeal in cherishing the spirit and supporting the character of federalists.
