Always keep the search for and use of enemies under control. It is clarity you want, not paranoia. It is the downfall of many tyrants to see an enemy in everyone. They lose their grip on reality and become hopelessly embroiled in the emotions their paranoia churns up. By keeping an eye on possible enemies, you are simply being prudent and cautious. Keep your suspicions to yourself, so that if you’re wrong, no one will know.
