Mark Twain Quotes
“Censorship is telling a man he can't have a steak just because a baby can't chew it.”
Often attributed to Twain online, but unsourced. Alternate source: "The whole principle [of censorship] is wrong. It's like demanding that grown men live on skim milk because the baby can't have steak." — Robert Heinlein, The Man Who Sold the Moon, 1951, p. 188.

“The lack of money is the root of all evil.”
This appears in Twain's posthumous The Refuge of the Derelicts (1905), but it had already been published by other writers.
The earliest citation found in Google Books is a 1872 article by Richard Bowker: "Our Crime Against Crimes" https://books.google.com/books?id=YZgBAAAAYAAJ&pg=PA68&dq=The+lack+of+money+is+the+root+of+all+evil&hl=en&sa=X&ved=0ahUKEwjWi5DE1crLAhUI3mMKHeSdB0YQ6AEIKzAB#v=onepage&q=%22lack%20of%20money%22&f=false, in The Herald of Health, vol. 19 no. 2, New York: Wood & Holbrook, February 1872. The saying is placed within quotation marks, perhaps indicating that it was already well-known.
A precursor is found in an article from 1859 https://books.google.com/books?id=gpdEAQAAMAAJ&pg=PA209&dq=The+lack+of+money+is+the+root+of+all+evil&hl=en&sa=X&ved=0ahUKEwjWi5DE1crLAhUI3mMKHeSdB0YQ6AEINTAD#v=onepage&q=%22lack%20of%20gold%22&f=false: It is very well to repeat, parrot-like, the old axiom that “the love of gold is the root of all evil;” but it is very certain that in truth—the lack of gold is the great incentive to crime.

Context: The people of those foreign countries are very, very ignorant. They looked curiously at the costumes we had brought from the wilds of America. They observed that we talked loudly at table sometimes. They noticed that we looked out for expenses and got what we conveniently could out of a franc, and wondered where in the mischief we came from. In Paris they just simply opened their eyes and stared when we spoke to them in French! We never did succeed in making those idiots understand their own language.

Context: Your race, in its poverty, has unquestionably one really effective weapon—laughter. Power, Money, Persuasion, Supplication, Persecution—these can lift at a colossal humbug,—push it a little—crowd it a little—weaken it a little, century by century: but only Laughter can blow it to rags and atoms at a blast. Against the assault of Laughter nothing can stand.
