"For one thing, there have been many revolutions in Galactic histyory that have overthrown tyrannies, sometimes on individual planets, sometimes in groups of them, occasionally in the Empire itself or in the pre-Imperial regional governments. Often, this has only meant a change in tyranny. In other words, one ruling class is replaced by another - sometimes by one that is more efficient and therefore still more capable of maintaining itself - while the poor and downtrodden remain poor and downtrodden or beocme even worse off."

Davan, listening intently, said, "I'm aware of that. We all are. Perhaps we can learn from the past and know better what to avoid. Besides, the tyranny that now exists is actual. That which may exist in the future is merely potential. If we are always to draw back from change with the thought that the change may be for the worse, then there is no hope at all of ever escaping injustice."
