Before God, there is neither Greek nor barbarian, neither rich nor poor; and the slave is as good as his master, for by birth all men are free; they … - John Dalberg-Acton, 1st Baron Acton

From this universal degradation the world was rescued by the most gifted of the nations. Athens, which like other cities was distracted and oppressed by a privileged class, avoided violence and appointed Solon to revise its laws. ...Solon gave a share of power proportioned to the demands made on their resources. The poorest classes were exempt from direct taxes, but were excluded from office. Solon gave them a voice in electing magistrates from the classes above them, and the right of calling them to account. This concession... was the beginning of a mighty change. It introduced the idea that a man ought to have a voice in selecting those to whose rectitude and wisdom he is compelled to trust his fortune, his family, and his life. And this idea completely inverted the notion of human authority, for it inaugurated the reign of moral influence... Government by consent superseded government by compulsion, and the pyramid which had stood on a point was made to stand upon its base. By making every citizen the guardian of his own interest Solon admitted the element of Democracy into the State.

The idea that the ends of government justify the means employed, was worked into system by Machiavelli. He was an acute politician, sincerely anxious that the obstacles to the intelligent government of Italy should be swept away. It appeared to him that the most vexatious obstacle to intellect is conscience, and that the vigorous use of statecraft necessary for the success of difficult schemes would never be made if governments allowed themselves to be hampered by the precepts of the copy-book. His audacious doctrine was avowed in the succeeding age, by men whose personal character otherwise stood high. They saw that in critical times good men have seldom strength for their goodness, and yield to those who have grasped the meaning of the maxim that you cannot make an omelette if you are afraid to break the eggs. They saw that public morality differs from private, because no government can turn the other cheek, or can admit that mercy is better than justice. And they could not define the difference, or draw the limits of exception; or tell what other standard for a nation’s acts there is than the judgment which heaven pronounces in this world by success.

The way was paved for absolute monarchy to triumph over the spirit and institutions of a better age, not by isolated acts of wickedness, but by a studied philosophy of crime, and so thorough a perversion of the moral sense that the like of it had not been since the Stoics reformed the morality of paganism. The clergy who had in so many ways served the cause of freedom during the prolonged strife against feudalism and slavery, were associated now with the interest of royalty.
