Marxian exploitation is the exploitation of people's lack of understanding of economics.
Robert NozickOne way to determine if a view is inadequate is to check its consequences in particular cases, sometimes extreme ones, but if someone always decided what the result should be in any case by applying the given view itself, this would preclude discovering it did not correctly fit the case. Readers who hold they would plug in to the machine should notice whether their first impulse was not to do so, followed later by the thought that since only experiences could matter, the machine would be all right after all.
