" Human beings often cling to their certainties for fear that their opinions will be proven false. But a certainty that cannot be called into question is not a certainty. Solid certainties are those that survive questioning. In order to accept questioning as the foundation for our voyage toward knowledge, we must be humble enough to accept that today’s truth may become tomorrow’s falsehood. "
