2. Different Significations of the word Liberty. There is no word that admits of more various significations, and has made more varied impressions on the human mind, than that of liberty. Some have taken it as a means of deposing a person on whom they had conferred a tyrannical authority; others for the power of choosing a superior whom they are obliged to obey; others for the right of bearing arms, and of being thereby enabled to use violence; others, in fine, for the privilege of being governed by a native of their own country, or by their own laws.1 A certain nation for a long time thought liberty consisted in the privilege of wearing a long beard.2 Some have annexed this name to one form of government exclusive of others: those who had a republican taste applied it to this species of polity; those who liked a monarchical state gave it to monarchy.3 Thus they have all applied the name of liberty to the government most suitable to their own customs and inclinations: and as in republics the people have not so constant and so present a view of the causes of their misery, and as the magistrates seem to act only in conformity to the laws, hence liberty is generally said to reside in republics, and to be banished from monarchies. In fine, as in democracies the people seem to act almost as they please, this sort of government has been deemed the most free, and the power of the people has been confounded with their liberty.
3. In what Liberty consists. It is true that in democracies the people seem to act as they please; but political liberty does not consist in an unlimited freedom. In governments, that is, in societies directed by laws, liberty can consist only in the power of doing what we ought to will, and in not being constrained to do what we ought not to will.
We must have continually present to our minds the difference between independence and liberty. Liberty is a right of doing whatever the laws permit, and if a citizen could do what they forbid he would be no longer possessed of liberty, because all his fellow-citizens would have the same power.
4. The same Subject continued. Democratic and aristocratic states are not in their own nature free. Political liberty is to be found only in moderate governments; and even in these it is not always found. It is there only when there is no abuse of power. But constant experience shows us that every man invested with power is apt to abuse it, and to carry his authority as far as it will go. Is it not strange, though true, to say that virtue itself has need of limits?
To prevent this abuse, it is necessary from the very nature of things that power should be a check to power. A government may be so constituted, as no man shall be compelled to do things to which the law does not oblige him, nor forced to abstain from things which the law permits."
