"This young lady, who instantly overwhelmed me..." - Quote by Karl Marx

“History calls those men the greatest who have ennobled themselves by working for the common good; experience acclaims as happiest the man who has made the greatest number of people happy.”

“There is no royal road to science, and only those who do not dread the fatiguing climb of its steep paths have a chance of gaining its luminous summits. (Preface to the French edition).”

“There is something in human history like retribution; and it is a rule of historical retribution that its instrument be forged not by the offended, but by the offender himself. The first blow dealt to the French monarchy proceeded from the nobility, not from the peasants. The Indian revolt does not commence with the ryots, tortured, dishonoured and stripped naked by the British, but with the sepoys, clad, fed and petted, fatted and pampered by them.”

“Travel is lethal to prejudice.”

“Bigotry is the disease of ignorance.”

“Bigotry is an odd thing. To be bigoted you have to be absolutely sure you are right and nothing makes that surety and righteousness like continence. Continence is the foe of heresy.”

“The glory of this land has been its capacity for transcending the moral evils of our past. For example, the long struggle of minority citizens for equal rights, once a source of disunity and civil war, is now a point of pride for all Americans. We must never go back. There is no room for racism, anti-Semitism, or other forms of ethnic and racial hatred in this country.”

“Why should [Uncle Sam] send 20 billion dollars down there [South America], which is going to go down the drain every time you have a racial in - incident in this country?”

“The common enemy is the white man.”
