A plural Legislature is as necessary to good Government as a single Executive. It is not enough that your Legislature should be numerous; it should also be divided. Numbers alone are not a sufficient Barrier against the Impulses of Passion, the Combinations of Interest, the Intrigues of Faction, the Haste of Folly, or the Spirit of Encroachment. One Division should watch over and controul the other, supply its Wants, correct its Blunders, and cross its Designs, should they be criminal or erroneous. Wisdom is the specific Quality of the Legislature, grows out of the Number of the Body, and is made up of the Portions of Sense and Knowledge which each Member brings to it.
— Benjamin Franklin

In the weakness of one kind of authority, and in the fluctuation of all, the officers of an army will remain for some time mutinous and full of faction, until some popular general, who understands the art of conciliating the soldiery, and who possesses the true spirit of command, shall draw the eyes of all men upon himself. Armies will obey him on his personal account. There is no other way of securing military obedience in this state of things.

Faction quotes
Picture quote about Faction

In perpetrating a revolution, there are two requirements: someone or something to revolt against and someone to actually show up and do the revolting. Dress is usually casual and both parties may be flexible about time and place, but if either faction fails to attend, the whole enterprise is likely to come off badly.
— Woody Allen

Abuse of words has been the great instrument of sophistry and chicanery, of party, faction, and division of society.
— John Adams

It is impossible that the whisper of a faction should prevail against the voice of a nation.
— faction quotation by Lord John Russell
