"Anyone serious about saving the world today must first discard the dominant philosophy of the culture. Stand on your own as much as if you moved to a separate valley, like in Atlas Shrugged. Check your premises; define your convictions rationally. Do not take anything on faith; do not believe that your elders know what they're doing; because they don't."
~ Ayn Rand, from the Q&A at the Ford Hall Forum during the 1970s, appearing in the recent book Ayn Rand Answers
