But the large toleration these considerations dictate has limits. For example, though we tolerate, and rightly tolerate, the propaganda of Anarchism as a political theory which embraces all that is valuable in the doctrine of Laisser-Faire and the method of Free Trade as well as all that is shocking in the views of Bakounine, we clearly cannot, or at all events will not, tolerate assassination of rulers on the ground that it is "propaganda by deed" or sociological experiment. A play inciting to such an assassination cannot claim the privileges of heresy or immorality, because no case can be made out in support of assassination as an indispensable instrument of progress. Now it happens that we have in the Julius Caesar of Shakespear a play which the Tsar of Russia or the Governor-General of India would hardly care to see performed in their capitals just now. It is an artistic treasure; but it glorifies a murder which Goethe described as the silliest crime ever committed. It may quite possibly have helped the regicides of 1649 to see themselves, as it certainly helped generations of Whig statesmen to see them, in a heroic light; and it unquestionably vindicates and ennobles a conspirator who assassinated the head of the Roman State not because he abused his position but solely because he occupied it, thus affirming the extreme republican principle that all kings, good or bad, should be killed because kingship and freedom cannot live together. Under certain circumstances this vindication and ennoblement might act as an incitement to an actual assassination as well as to Plutarchian republicanism; for it is one thing to advocate republicanism or royalism: it is quite another to make a hero of Brutus or Ravaillac, or a heroine of Charlotte Corday. Assassination is the extreme form of censorship; and it seems hard to justify an incitement to it on anti-censorial principles. The very people who would have scouted the notion of prohibiting the performances of Julius Caesar at His Majesty's Theatre in London last year, might now entertain very seriously a proposal to exclude Indians from them, and to suppress the play completely in Calcutta and Dublin; for if the assassin of Caesar was a hero, why not the assassins of Lord Frederick Cavendish, Presidents Lincoln and McKinley, and Sir Curzon Wyllie? Here is a strong case for some constitutional means of preventing the performance of a play. True, it is an equally strong case for preventing the circulation of the Bible, which was always in the hands of our regicides; but as the Roman Catholic Church does not hesitate to accept that consequence of the censorial principle, it does not invalidate the argument.
