Jealousy

The principle of equality, which makes men independent of each other, gives them a habit and a taste for following, in their private actions, no other guide but their own will. This complete independence, which they constantly enjoy towards their equals and in the intercourse of private life, tends to make them look upon all authority with a jealous eye, and speedily suggests to them the notion and the love of political freedom. Men living at such times have a natural bias to free institutions. Take any one of them at a venture, and search if you can his most deep-seated instincts; you will find that of all governments he will soonest conceive and most highly value that government, whose head he has himself elected, and whose administration he may control. (De Tocqueville Democracy in America) The jealous are troublesome to others, but a torment to themselves. -William Penn
