David Hume on Freedom of the PressEssays Moral, Political, Literary (1742), Essay 2.
It is a very comfortable reflection to the lovers of liberty, that this peculiar privilege of Britain is of a kind that cannot easily be wrested from us, but must last as long as our government remains, in any degree, free and independent. It is seldom, that liberty of any kind is lost all at once. Slavery has so frightful an aspect to men accustomed to freedom, that it must steal upon them by degrees, and must disguise itself in a thousand shapes, in order to be received. But, if the liberty of the press ever be lost, it must be lost at once. The general laws against sedition and libelling are at present as strong as they possibly can be made. Nothing can impose a farther restraint, but either the clapping an Imprimatur upon the press, or the giving to the court very large discretionary powers to punish whatever displeases them. But these concessions would be such a bare-faced violation of liberty, that they will probably be the last efforts of a despotic government. We may conclude, that the liberty of Britain is gone for ever when these attempts shall succeed.
