Liberty and Equality.

Two ideas of the Enlightenment that many believed to have sparked the French Revolution.

My questions are

1. Whether or not these ideas sparked revolutions that actually delivered liberty and equality to the people.

2. If liberty and equality ever existed, do exist, or can exist in society.

So are liberty and equality the idealist essentials for a utopian society, or simply the slogans of a misled dystopia?
