Suppose there were an experience machine that would give you any experience you desired. Superduper neuropsychologists could stimulate your brain so that you would think and feel you were writing a great novel, or making a friend, or reading an interesting book. All the time you would be floating in a tank, with electrodes attached to your brain.

Robert NozickThe terminology of philosophical art is coercive: arguments are powerful and best when they are knockdown, arguments force you to a conclusion, if you believe the premisses you have to or must believe the conclusion, some arguments do not carry much punch, and so forth. A philosophical argument is an attempt to get someone to believe something, whether he wants to beleive it or not. A successful philosophical argument, a strong argument, forces someone to a belief.
