What is the point of having original thought anyway? All people who think independently are small rowboats disembarking from the galleon to forge their own path through the cold, deep sea. They linger for a while, but are inevitably thrashed apart by the waves. Only the galleon of popular ideology has the mass to survive the ocean.
They sail their own doomed paths in the hope that one day the galleon will turn and follow them, if only for a while, and be closer to destination Truth than it was without them.
