Politics Is The Mind-Killer http://lesswrong.com/lw/gw/politics_is_the_mindkiller/ (February 2007) 
Context: People go funny in the head when talking about politics. The evolutionary reasons for this are so obvious as to be worth belaboring: In the ancestral environment, politics was a matter of life and death. And sex, and wealth, and allies, and reputation... When, today, you get into an argument about whether "we" ought to raise the minimum wage, you're executing adaptations for an ancestral environment where being on the wrong side of the argument could get you killed... Politics is an extension of war by other means. Arguments are soldiers. Once you know which side you're on, you must support all arguments of that side, and attack all arguments that appear to favor the enemy side; otherwise it's like stabbing your soldiers in the back — providing aid and comfort to the enemy.
                                    
“Where execution is dominant, as it is in the individual events of a war whether great or small, then intellectual factors are reduced to a minimum.”

Context: It was a terrible war. The idea that the cost of the war is due to Lincoln is simply absurd. It was a terrible war because the country was deeply divided, and the question of the future of the nation, whether or not it would be based upon principles recognized as principles of individual liberty, or whether the idea of one race dominating another race would be accepted as a means for governance. Let me just read one short statement here that might interest you. "Since the Civil War, in which the Southern States were conquered, against all historical logic and sound sense, the American people have been in a condition of political and popular decay.... The beginnings of a great new social order based on the principle of slavery and inequality were destroyed by that war, and with them also the embryo of a future truly great America." That has been the position of defenders of the Confederacy from Alexander Stephens through Thomas DiLorenzo. Do you know the man who said that was Adolf Hitler?

                                        Though Rickover quoted this, he did not claim to be the author of the statement. Using it in "The World of the Uneducated" in The Saturday Evening Post (28 November 1959), he prefaces it with "As the unknown sage puts it..." — It has sometimes been attributed to Eleanor Roosevelt, but without definite citation.
