Robert A. Heinlein

• That we were slaves I had known all my life & nothing could be done about it. True, we weren’t bought & sold – if Authority held monopoly over what we had to have & what we could sell to buy it, we were slaves.
  The Moon is A Harsh Mistress
  
• No amount of force can control a free man, whose mind is free. No, not the rack nor the atomic bomb, not anything. You can’t conquer a free man; the most you can do is kill him.
• There is no worse tyranny than to force a man to pay for what he does not want merely because you think it would be good for him.
• Taxes are not levied for the benefit of the taxed.
