This is the reason of an appearance very frequent in madmen; that they remain whole days and nights, sometimes whole years, in the constant repetitio… - Edmund Burke

I wished to warn the people against the greatest of all evils, — a blind and furious spirit of innovation, under the name of reform.

[The Aliens Bill is necessary] to keep out of England those murderous atheists, who would pull down church and state; religion and God; morality and happiness... He mentioned the circumstance of three thousand daggers having been bespoke at Birmingham by an Englishman, of which seventy had been delivered. It was not ascertained how many of these were to be exported, and how many were intended for home consumption [Here Mr. Burke drew out a dagger which he had kept concealed, and with much vehemence of action threw it on the floor.] This, said he, pointing to the dagger, is what you are to gain by an alliance with France: wherever their principles are introduced, their practice must follow. You must guard against their principles; you must proscribe their persons. He then held the dagger up to public view, which he said never could have been intended for fair and open war, but solely for murderous purposes. It is my object, said he, to keep the French infection from this country; their principles from our minds, and their daggers from our hearts. I vote for this bill, because I consider it the means of saving my life and all our lives, from the hands of assassins. I vote for it, because it will break the abominable system of the modern Pantheon, and prevent the introduction of French principles and French daggers. When they smile, I see blood trickling down their faces; I see their insidious purposes; I see that the object of all their cajoling is—blood! I now warn my countrymen to beware of these execrable philosophers, whose only object it is to destroy every thing that is good here, and to establish immorality and murder by precept and example—"Hic niger est hunc tu Romane caveto." ["Such a man is evil; beware of him, Roman." Horace, Satires I. 4. 85.]

There is, however, a limit at which forbearance ceases to be a virtue.
