Well that's bad news for the Israelis and Palestinians.

When is Churchill supposed to have said this? What is the source for this quotation?

There is no conspiracy here. Morgenthau was simply talking about the de-nazification of Germany. That put's rather a different spin of things.

There was no 29 February in 1925 ...

Rousseau had it right when he wrote: "The English people believes itself to be free; it is gravely mistaken; it is free only during the election of Members of Parliament; as soon as the Members are elected, the people are enslaved; it is nothing. In the brief moment of its freedom, the English people make such a use of that freedom that it deserves to lose it"

I don't see anybody standing up for the Scots and their independence over the Libyan case. If the Americans want to be independent, they should stand up for Scottish independence.

Wendell Phillips was actually referring to a dictum by the Irish politician of the eighteenth century, John Philpott Curran: “It is the common fate of the indolent to see their rights become a prey to the active. The condition upon which God hath given liberty to man is eternal vigilance; which condition if he break, servitude is at once the consequence of his crime and the punishment of his guilt” It was such a well-known quotation both then and now that Wendell Phillips would have expected his audience to spot the allusion. There was no question of plagiarism.

What Jefferson actually said in a letter of 1787 was "Lethargy [is] the forerunner of death to the public liberty."

Mencken's next sentence (which was omitted from your extracts) was: "What was the practical effect of the battle of Gettysburg? What else than the destruction of the old sovereignty of the states, i.e., of the people of the States?"

Gladstone: “Money should fructify in the pockets of the people”

Montesquieu: “It is sometimes necessary to change certain laws. But the occasion is rare and when it arises one must only touch them with a trembling hand”

I think the quote is from an "Introductory Lecture" which Housman delivered on October 3, 1892 at University College, London. The full quote runs as follows: “The house of delusions is cheap to build, but draughty to live in, and ready at any instant to fall.”

Dr Laura was not the first to come up with this thought - compare: Dryden: “Virtue is its own reward” Dryden (a great classicist) was in turn no doubt inspired by several classical authors, including: 1) Cicero: "Honor est praemium virtutis" 2) Seneca: “The reward of a good deed is to have done it” 3) Sophocles: "Rather fail with honour than succeed by fraud."
