In the mid-nineteenth century, Nicaraguans were at odds with one another over how their land should be run. Their odds grew into strife between two cities, León and Granada, and it had some nasty turns. To solve their problems, the people of León invited William Walker into the country. Walker was a brilliant and ambitious fellow, both a lawyer and a doctor, who had tried to conquer part of Mexico with a private army. That venture failed, but his reputation was widespread, so the Nicaraguans of León recruited him in their struggle against Granada. Walker did what they desired and defeated Granada, and then he took over the presidency and instituted rules and laws, including one that permitted slavery and another that made English the official language. Uh, Oh! Maldito! Things had not turned out as the residents of León had thought they would.
Recall those questions in the first paragraph above? Walker was qualified, but he was neither trustworthy nor concerned. Now remember a previous essay of mine, where I told the tale of Pyrrhus of Epirus. The people of Tarentum invited Pyrrhus into their city-state to wage war on the Romans. More than a couple of thousand years before the Nicaraguans suffered the intrusion of William Walker, the Tarentines found their lives changed for the worse by the rules and laws instituted by an outsider in control. Pyrrhus, like Walker after him, had his own interests had heart. Yes, he had the qualifications, but no, he wasn’t the trustworthy person Tarentines thought he was.
In both instances, nineteenth-century CE and twenty-fourth century BCE, the locals did not find ways to solve their own problems, and in both instances, they essentially gave away their freedoms and ways of life to a stranger. Now, maybe there are stories of outsiders entering the inside and solving problems without dire consequences for the insiders. Maybe you learned of such outsiders in some history class or through personal experience. If so, then on reexamination you should see that in such cases, the outsiders were qualified, trustworthy, and concerned.
Those you seek for help should be qualified, trustworthy, and concerned. When you find the outsider that fills those requirements, let that stranger in.
