„Suppose you want to teach the "cat" concept to a very young child. Do you explain that a cat is a relatively small, primarily carnivorous mammal with retractible claws, a distinctive sonic output, etc.? I'll bet not. You probably show the kid a lot of different cats, saying "kitty" each time, until it gets the idea. To put it more generally, generalizations are best made by abstraction from experience. They should come one at a time; too many at once overload the circuits.“

„It's the story of a place called Mouseland. Mouseland was a place where all the little mice lived and played, were born and died. And they lived much the same as you and I do. They even had a Parliament. And every four years they had an election. Used to walk to the polls and cast their ballots. Some of them even got a ride to the polls. And got a ride for the next four years afterwards too. Just like you and me. And every time on election day all the little mice used to go to the ballot box and they used to elect a government. A government made up of big, fat, black cats. Now if you think it strange that mice should elect a government made up of cats, you just look at the history of Canada for last 90 years and maybe you'll see that they weren't any stupider than we are. Now I'm not saying anything against the cats. They were nice fellows. They conducted their government with dignity. They passed good laws--that is, laws that were good for cats. But the laws that were good for cats weren't very good for mice. One of the laws said that mouseholes had to be big enough so a cat could get his paw in. Another law said that mice could only travel at certain speeds--so that a cat could get his breakfast without too much physical effort. All the laws were good laws. For cats. But, oh, they were hard on the mice. And life was getting harder and harder. And when the mice couldn't put up with it any more, they decided something had to be done about it. So they went en masse to the polls. They voted the black cats out. They put in the white cats. Now the white cats had put up a terrific campaign. They said: "All that Mouseland needs is more vision." They said:"The trouble with Mouseland is those round mouseholes we got. If you put us in we'll establish square mouseholes." And they did. And the square mouseholes were twice as big as the round mouseholes, and now the cat could get both his paws in. And life was tougher than ever. And when they couldn't take that anymore, they voted the white cats out and put the black ones in again. Then they went back to the white cats. Then to the black cats. They even tried half black cats and half white cats. And they called that coalition. They even got one government made up of cats with spots on them: they were cats that tried to make a noise like a mouse but ate like a cat. You see, my friends, the trouble wasn't with the colour of the cat. The trouble was that they were cats. And because they were cats, they naturally looked after cats instead of mice. Presently there came along one little mouse who had an idea. My friends, watch out for the little fellow with an idea. And he said to the other mice, "Look fellows, why do we keep on electing a government made up of cats? Why don't we elect a government made up of mice?" "Oh," they said, "he's a Bolshevik. Lock him up!"“

—  Tommy Douglas Scottish-born Canadian politician 1904 - 1986

So they put him in jail. But I want to remind you: that you can lock up a mouse or a man but you can't lock up an idea!

„You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat.“

—  Albert Einstein German-born physicist and founder of the theory of relativity 1879 - 1955

Earliest published version found on Google Books with this phrasing is in the 1993 book The Internet Companion: A Beginner's Guide to Global Networking by Tracy L. LaQuey and Jeanne C. Ryer, p. 25 http://books.google.com/books?id=sP5SAAAAMAAJ&q=meowing#search_anchor. However, the quote seems to have been circulating on the internet earlier than this, appearing for example in this post from 1987 http://groups.google.com/group/comp.lang.c/msg/cc89abb5e065d23f?hl=en and this one from 1985 http://groups.google.com/group/net.sources.games/browse_thread/thread/846af15b5a38c35/3d6d5a639c24bba3. No reference has been found that cites a source in Einstein's original writings, and the quote appears to be a variation of an old joke that dates at least as far back as 1866, as discussed in this entry from the "Quote Investigator" blog http://quoteinvestigator.com/2012/02/24/telegraph-cat/#more-3387. A variant was told by Thomas Edison, appearing in The Diary and Sundry Observations of Thomas Alva Edison (1948), p. 216 http://books.google.com/books?id=NXtEAAAAIAAJ&q=edinburgh#search_anchor: "When I was a little boy, persistently trying to find out how the telegraph worked and why, the best explanation I ever got was from an old Scotch line repairer who said that if you had a dog like a dachshund long enough to reach from Edinburgh to London, if you pulled his tail in Edinburgh he would bark in London. I could understand that. But it was hard to get at what it was that went through the dog or over the wire." A variant of Edison's comment can be found in the 1910 book Edison, His Life and Inventions, Volume 1 by Frank Lewis Dyer and Thomas Commerford Martin, p. 53 http://books.google.com/books?id=qN83AAAAMAAJ&pg=PA53#v=onepage&q&f=false.
The wireless telegraph is not difficult to understand. The ordinary telegraph is like a very long cat. You pull the tail in New York, and it meows in Los Angles. The wireless is the same, only without the cat.
Variant, earliest known published version is How to Think Like Einstein by Scott Thorpe (2000), p. 61 http://books.google.com/books?id=9yrYQxBgIYEC&lpg=PP1&pg=PA61#v=onepage&q&f=false. Appeared on the internet before that, as in this archived page from 12 October 1999 http://web.archive.org/web/19991012152820/http://stripe.colorado.edu/%7Ejudy/einstein/advice.html
