And remember, where you have a concentration of power in a few hands, all too frequently men with the mentality of gangsters get control. History has proven that.

By liberty I mean the assurance that every man shall be protected in doing what he believes to be his duty against the influences of authority and majorities, custom and opinion.

Progress, the religion of those who have none.

Power tends to corrupt and absolute power corrupts absolutely. Great men are almost always bad men, even when they exercise influence and not authority: still more when you superadd the tendency or the certainty of corruption by authority.

Though oppression may give rise to violent and repeated outbreaks, like the convulsions of a man in pain, it cannot mature a settled purpose and plan of regeneration, unless a new notion of happiness is joined to the sense of present evil.

Liberty is not a means to a higher political end. It is itself the highest political end...liberty is the only object which benefits all alike, and provokes no sincere opposition...The danger is not that a particular class is unfit to govern. ~ Every class is unfit to govern ... Power tends to corrupt, and absolute power corrupts absolutely. Great men are almost always bad men.

Political differences essentially depend on disagreement in moral principles.
