I am therefore of opinion that some one social power must always be made to predominate over the others; but I think that liberty is endangered when this power is checked by no obstacles which may retard its course, and force it to moderate its own vehemence.

Context

“The error arose from too much attention being paid to the actual struggle which was going on between the nobles and the people, without considering the probable issue of the contest, which was in reality the important point. When a community really has a mixed government, that is to say, when it is equally divided between two adverse principles, it must either pass through a revolution or fall into complete dissolution.
I am therefore of opinion that some one social power must always be made to predominate over the others; but I think that liberty is endangered when this power is checked by no obstacles which may retard its course, and force it to moderate its own vehemence. Unlimited power is in itself a bad and dangerous thing; human beings are not competent to exercise it with discretion, and God alone can be omnipotent, because His wisdom and His justice are always equal to His power.” source
