It was in the most patient period of Roman servitude that themes of tyrannicide made the ordinary exercise of boys at school — quum perimit sævos classis numerosa tyrannos. In the ordinary state of things, it produces in a country like ours the worst effects, even on the cause of that liberty which it abuses with the dissoluteness of an extravagant speculation. Almost all the high-bred republicans of my time have, after a short space, become the most decided, thorough-paced courtiers; they soon left the business of a tedious, moderate, but practical resistance to those of us whom, in the pride and intoxication of their theories, they have slighted as not much better than Tories. Hypocrisy, of course, delights in the most sublime speculations, for, never intending to go beyond speculation, it costs nothing to have it magnificent. But even in cases where rather levity than fraud was to be suspected in these ranting speculations, the issue has been much the same. These professors, finding their extreme principles not applicable to cases which call only for a qualified or, as I may say, civil and legal resistance, in such cases employ no resistance at all. It is with them a war or a revolution, or it is nothing. Finding their schemes of politics not adapted to the state of the world in which they live, they often come to think lightly of all public principle, and are ready, on their part, to abandon for a very trivial interest what they find of very trivial value. Some, indeed, are of more steady and persevering natures, but these are eager politicians out of parliament who have little to tempt them to abandon their favorite projects. They have some change in the church or state, or both, constantly in their view. When that is the case, they are always bad citizens and perfectly unsure connections. For, considering their speculative designs as of infinite value, and the actual arrangement of the state as of no estimation, they are at best indifferent about it. They see no merit in the good, and no fault in the vicious, management of public affairs; they rather rejoice in the latter, as more propitious to revolution. They see no merit or demerit in any man, or any action, or any political principle any further than as they may forward or retard their design of change; they therefore take up, one day, the most violent and stretched prerogative, and another time the wildest democratic ideas of freedom, and pass from one to the other without any sort of regard to cause, to person, or to party.
