One of the great minds of the past, considered the most astute historian of liberty and its development, was Lord Emerich Edward Dalberg Acton (1834-1902).
When we get weary of the battle, just consider what Lord Acton tells us from his learned perspective of history's march....
At all times sincere friends of freedom have been rare, and its
triumphs have been due to minorities...
It's our turn to do the heavy lifting.
Some other gems from The History of Freedom in Antiquity. Keep in mind, this was written in 1877.
In every age [freedom's] progress has been beset by its natural enemies, by
ignorance and superstition...
By liberty I mean the assurance that every man shall be protected in doing what he believes his duty, against the influence of authority and majorities, custom and opinion. The state is competent to assign duties and draw the line between good and evil only in its own immediate sphere.
The most certain test by which we judge whether a country is really free is the amount of security enjoyed by minorities.
Now Liberty and good government do not exclude each other; and there are excellent reasons why they should go together; but they do not necessarily go together. Liberty is not a means to a higher political end. It is itself the highest political end. It is not for the sake of a good public administration that it is required, but for security in the pursuit of the highest objects of civil society, and of private life.
