Smedley Butler quotes are some of the most influential in the world in regard to military and war. At the time of his death in 1940 Major General Smedley Darlington Butler was the most decorated Marine in American history. His 16 medals included two Medals of Honor and the Brevet Medal, all for separate acts of heroism. Following his military service Butler revealed a supposed plot to overthrow the U.S. government, as well as published War Is a Racket, a scathing criticism of American wars for profit.

Very few writers achieve an image that overshadows their actual body of work, but boy, is Dr. Hunter S. Thompson ever one of them. Hunter S. Thompson quotes are some of the most bizarre (yet insightful) quotes out there. His persona of an acid-soaked degenerate frantically pecking away at the keys of an electric typewriter while surrounded by mounds of rotting, half-eaten grapefruits isn’t entirely spot-on, however. That has been largely played up, especially for the sake of movies like Where the Buffalo Roam and Fear and Loathing in Las Vegas.

Hailed as the godfather of conservative libertarianism, Milton Friedman quotes openly attacked Keynesianism in an era when most economists widely accepted its fundamental premises. Friedman won the 1976 Nobel Prize in Economic Sciences “for his achievements in the fields of consumption analysis, monetary history and theory and for his demonstration of the complexity of stabilization policy.” As a leader of the Chicago school of economics he taught several of the country’s future preeminent economists including Gary Becker, Robert Fogel, and Thomas Sowell.

Renowned Austrian school economist. Founder and former leading theoretician of anarcho-capitalism. Passionate historical revisionist. Arguably the preeminent libertarian thinker of the 20th century. Whenever you see the colors black and yellow laid side by side, the first man who comes to your mind should be Murray Newton Rothbard. And needless to say, when you read Murray Rothbard quotes you should pay attention.

Alongside Isaac Asimov and Arthur C. Clarke, Robert A. Heinlein represents the third of the “Big Three” science fiction authors. While his genre is arguably best known for far-fetched contrivances and other elements that would look right at home in a fantasy novel, Heinlein is revered for pioneering the “hard” science fiction subgenre that puts logic and scientific accuracy in the front seat.

An Austrian School economist, Ludwig Heinrich Edler von Mises devoted much of his life to writing and educating on the subject of classical liberalism. While several classical libertarians including John Locke and Jean-Baptiste Say preceded him, Mises’ revival of the ideology following the Second World War has cemented his place as one of libertarianism’s most revered figures.

Teddy, as he was affectionately called (although seldom to his face) was the 26th president of the United States, and considered by more than a few to have been the greatest. He was also a statesman, writer, conservationist, naturalist, hunter, ornithologist, taxidermist, cowboy, and war veteran – he was posthumously awarded the Medal of Honor in 2001.

A culturally conservative libertarian, Hoppe founded the The Property and Freedom Society in 2006. His goal was twofold: to explain the requirements and features of a free, stateless natural order, and to expose the state itself as “an institution run by gangs of murderers, plunderers and thieves, surrounded by willing executioners, propagandists, sycophants, crooks, liars, clowns, charlatans, dupes and useful idiots.” Hoppe leaves little to interpretation regarding his feelings on government.

Who is Ayn Rand? Born to a middle-class Russian-Jewish family in 1905, Rand was treated to a front-row seat to the wonders of communism in action. Rand fled with her family to the Crimea following the “liberation” of her father’s pharmacy but ultimately returned to Saint Petersburg where she could attend university when she wasn’t busy starving. Due to her life experiences, Ayn Rand’s quotes are some of the most thought-provoking in the world.

Henry Hazlitt was an American journalist whose columns appeared regularly in Newsweek, The Nation, The Sun, and The New York Times. Although he wrote prodigiously – enough to fill 150 volumes, by his own estimation – Hazlitt will forever remain best known for his book Economics in One Lesson. The vast majority of Henry Hazlitt quotes invariably come from it.
