“Words are the litmus paper of the mind.”

Terry Pratchett book Small Gods

“These lectures have shown very clearly the difference between Roger and me. He's a Platonist and I'm a positivist. He's worried that Schrödinger's cat is in a quantum state, where it is half alive and half dead. He feels that can't correspond to reality. But that doesn't bother me. I don't demand that a theory correspond to reality because I don't know what it is. Reality is not a quality you can test with litmus paper. All I'm concerned with is that the theory should predict the results of measurements. Quantum theory does this very successfully. It predicts that the result of an observation is either that the cat is alive or that it is dead. It is like you can't be slightly pregnant: you either are or you aren't.”

Stephen Hawking book The Nature of Space and Time

During a debate with Roger Penrose in 1994 at the Isaac Newton Institute for Mathematical Sciences at the University of Cambridge, transcribed in The Nature of Space and Time (1996) by Stephen Hawking and Roger Penrose, p. 121 http://books.google.com/books?id=LstaQTXP65cC&lpg=PP1&dq=nature%20of%20space%20and%20time&pg=PA121#v=onepage&q=&f=false

“I have never given a litmus test to anyone that I have appointed to the bench…. I feel very strongly about those social issues, but I also place my confidence in the fact that the one thing that I do seek are judges that will interpret the law and not write the law.”

Ronald Reagan (1911–2004) American politician, 40th president of the United States (in office from 1981 to 1989)

Interview with LA Times http://www.reagan.utexas.edu/archives/speeches/1986/62386e.htm (23 June 1986)
1980s, Second term of office (1985–1989)
Context: I have never given a litmus test to anyone that I have appointed to the bench.... I feel very strongly about those social issues, but I also place my confidence in the fact that the one thing that I do seek are judges that will interpret the law and not write the law. We've had too many examples in recent years of courts and judges legislating. They're not interpreting what the law says and whether someone has violated it or not. In too many instances, they have been actually legislating by legal decree what they think the law should be, and that I don't go for. And I think that the two men that we're just talking about here, Rehnquist and Scalia, are interpreters of the Constitution and the law.

“Jan Mickelson: One of my litmus test questions to find out what kind of thinking process a candidate has done on this, is to ask my test question. Test question is: do you think that Roe v. Wade is the law of land?
Ron Paul: Well, they call it the law of the land, but I want to clarify that by getting rid of it. I think this is one example of the courts overstepping their bounds tremendously. Texas had a law against this violent act, and it went in to the federal courts and the Supreme Court. They overruled the state law, which should have been legitimate, and then came down on the side of legalizing killing a fetus, even into the 3rd trimester. But the fastest way to accomplish this is not through a constitutional amendment, or waiting till you get enough justices to overrule. You can pass a law in the Congress, which denies jurisdiction to the federal courts. So if Iowa or Texas or any state passes a law against abortion, you can't get it into the federal courts, and the states would decide this issue, as they decide all issues of violence: murder, manslaughter, theft, all this things are supposed to be state issues.”

Ron Paul (1935) American politician and physician

“It would let me protect the Earth from asteroids. In fact, for a small fee I would protect the Earth on a monthly basis, locating rocks that could be steered into the Earth and then not doing it if the cheque didn't bounce.
We could finally commodify sunlight. A large solar collector at the Earth Sun L1 would block all the light that otherwise falls on the unworthy and could be sold to those that deserve it (Litmus test is the same as with Operation Nice Planet You Have, Shame If Anything Were To Happen To It).”

James Nicoll (1961) Canadian fiction reviewer

“When humus remains constantly damp, without, however, being covered with water, it forms a very unpleasant smelling acid, which is more particularly, characterized by the property which it possesses of colouring blue litmus paper into red. This circumstance has long been known, and it is the reason that land and meadows which are not properly drained, and which exhibit these phenomena, are called sour. We have carefully examined these facts, and have endeavoured to discover the peculiar constitution of this acid. At first, we were inclined to regard it as being of a distinct nature, and having carbon for its base; but we have since become convinced that it is generally composed of acetic acid, and occasionally contains a portion of the phosphoric. This latter always adheres so firmly to the humus that it cannot be separated from it either by boiling or washing. The liquid in which the humus is boiled certainly acquires a slight acid flavour, but the greater part of the acid remains attached to the humus.
This acid or sour humus it not at all of a fertilizing nature; on the contrary, it is prejudicial to vegetation* Where it is very strong and pervades the whole of the humus, the soil only produces reeds, rushes, sedge, and other useless, unpalatable plants; and whenever these abound, it may be inferred that the soil contains a great deal of sour or acid humus… There are various means of getting rid of this baneful property, and rendering the humus fertile. It is well known that with the aid of alkalies, ashes, lime, and marl, humus may be deprived of its acidity, and rendered easily soluble… Heaths do not thrive where this humus does not exist, and when they have established themselves in one particular spot, they suffer few other plants to appear. This humus may be changed by a dressing composed of marl, lime, or ammonia; and where this has been mixed with the soil, the heaths, &c., speedily perish.”

Albrecht Thaer (1752–1828) German agronomist and an avid supporter of the humus theory for plant nutrition

“1/2 cup of hope and 1/2 cup of kindness seem like a litmus test by asking "Is the glass half empty or half full?" Nature shows us in every waking moment that where there is life, there is hope. And to quote the movie Horns starring Daniel Radcliffe and Juno Temple, "Man is not born evil. The Devil himself was a fallen angel," there is kindness in everyone if you dig deep enough.”

“Litmus test: If you can't describe Ricardo's Law of Comparative Advantage and explain why people find it counterintuitive, you don't know enough about economics to direct any criticism or praise at "capitalism" because you don't know what other people are referring to when they use that word.”

Eliezer Yudkowsky (1979) American blogger, writer, and artificial intelligence researcher
