These words had scarcely been written, when, as if to give them an emphatic contradiction, occurred the Government Press Prosecutions of 1858. That ill-judged interference with the liberty of public discussion has not, however, induced me to alter a single word in the text, nor has it at all weakened my conviction that, moments of panic excepted, the era of pains and penalties far political discussion has, in our own country, passed away. For, in the first place, the prosecutions were not persisted in; and in the second, they were never, properly speaking, political prosecutions. The offence charged was not that of criticizing institutions, or the acts or persons of rulers, but of circulating what was deemed an immoral doctrine, the lawfulness of Tyrannicide.

If the arguments of the present chapter are of any validity, there ought to exist the fullest liberty of professing and discussing, as a matter of ethical conviction, any doctrine, however immoral it may be considered. It would, therefore, be irrelevant and out of place to examine here, whether the doctrine of Tyrannicide deserves that title. I shall content myself with saying, that the subject has been at all times one of the open questions of morals, that the act of a private citizen in striking down a criminal, who, by raising himself above the law, has placed himself beyond the reach of legal punishment or control, has been accounted by whole nations, and by some of the best and wisest of men, not a crime, but an act of exalted virtue and that, right or wrong, it is not of the nature of assassination but of civil war. As such, I hold that the instigation to it, in a specific case, may be a proper subject of punishment, but only if an overt act has followed, and at least a probable connection can be established between the act and the instigation. Even then it is not a foreign government, but the very government assailed, which alone, in the exercise of self-defence, can legitimately punish attacks directed against its own existence.
