You can never plan the future by the past. - Edmund Burke

He insisted that it was a travelling delusion, that nations were not to interfere with each other: for if any nation endeavoured to confuse, to trample upon, violate or despise the rights of others, the interests of human society required that all should join against them. If, by the subversion of all law and religion, a nation adopts a malignant spirit to produce anarchy and mischief in other countries, it is the right of nations to go to war with them. In support of this doctrine, he quoted the authority of Vattel, who lays it down, that if one nation adopt principles injurious to all government and order, such a nation is to be opposed from principles of common safety. This, he insisted, was the spirit of France; and what was to keep the effects of it from England? War, and nothing else. Until, therefore, we could find that security in their principles and practices which could alone make peace permanent, he would never agree to prostrate the throne of Great Britain at the foot of any National Convention or Jacobin club whatever.

A kind Providence has placed in our breasts a hatred of the unjust and cruel, in order that we may preserve ourselves from cruelty and injustice. They who bear cruelty, are accomplices in it. The pretended gentleness which excludes that charitable rancour, produces an indifference which is half an approbation. They never will love where they ought to love, who do not hate where they ought to hate.

William Pitt the Younger: Never fear, Mr. Burke: depend on it we shall go on as we are, until the day of judgment.
Edmund Burke: Very likely, Sir. It is the day of no judgment that I am afraid of.
