The excerpt is taken from an essay of the Federalist Papers written by Alexander Hamilton, Federalist Papers. Although the passage isn't stated in a simple and more practical way, Hamilton's main point is to highlight that certain calls for moderation to the political parties are necessary. Without them, we'd be at the mercy of "that intolerant spirit which has, at all times, characterized political parties", referring to the vicious traits of abusive powers such as ambition, avarice, hostility, selfishness, among others.
