Six hundred years before the birth of Christ absolutism held unbounded sway. Throughout the East it was propped by the unchanging influence of priest… - John Dalberg-Acton, 1st Baron Acton

Most of this, I suppose, is undisputed, and calls for no enlargement. But the weight of opinion is against me when I exhort you never to debase the moral currency or to lower the standard of rectitude, but to try others by the final maxim that governs your own lives, and to suffer no man and no cause to escape the undying penalty which history has the power to inflict on wrong. The plea in extenuation of guilt and mitigation of punishment is perpetual. At every step we are met by arguments which go to excuse, to palliate, to confound right and wrong, and reduce the just man to the level of the reprobate. The men who plot to baffle and resist us are, first of all, those who made history what it has become. They set up the principle that only a foolish Conservative judges the present time with the ideas of the past; that only a foolish Liberal judges the past with the ideas of the present.

I have reached the end of my time, and have hardly come to the beginning of my task. In the ages of which I have spoken, the history of freedom was the history of the thing that was not. But since the Declaration of Independence, or, to speak more justly, since the Spaniards, deprived of their king, made a new government for themselves, the only known forms of Liberty, Republics and Constitutional Monarchy, have made their way over the world.

I am not thinking of those shining precepts which are the registered property of every school; that is to say — learn as much by writing as by reading; be not content with the best book; seek sidelights from the others; have no favourites; keep men and things apart; guard against the prestige of great names; see that your judgments are your own; and do not shrink from disagreement; no trusting without testing; be more severe to ideas than to actions; do not overlook the strength of the bad cause of the weakness of the good; never be surprised by the crumbling of an idol or the disclosure of a skeleton; judge talent at its best and character at its worst; suspect power more than vice, and study problems in preference to periods.
