The philosophy of positive thinking means being untruthful; it means being dishonest. It means seeing a certain thing and yet denying what you have seen; it means deceiving yourself and others. Positive thinking is the only bullshit philosophy that America has contributed to human thought — nothing else. Dale Carnegie, Napoleon Hill, and the Christian priest, Vincent Peale — all these people have filled the whole American mind with this absolutely absurd idea of a positive philosophy. And it appeals particularly to mediocre minds.
