"I didn't know, so it's not my fault."
Haru made excuses. Ren gave her a stern look.
"Ignorance is no excuse."
"But I can't be responsible for what I don't know."
Simon mediated. "There are types of ignorance."
"Types?" Haru asked.
"Ignorance of not knowing you don't know, and ignorance of choosing not to know."
Ren supplemented. "The former is unavoidable. The latter is deliberate."
"Choosing not to know?"
"Information is available, but you don't look. Don't learn. That's a choice."
Haru thought. "But knowing everything is impossible."
"Of course," Simon nodded. "So what you should know is important."
"Priorities?"
"Depending on your position and role, there are things you should know."
Ren gave an example. "A doctor not knowing medicine is sinful. Harms patients."
"Professional responsibility," Haru understood.
"Ordinary citizens also have things they should know," Simon said.
"Like what?"
"Social rules, basic human rights, policies of candidates you vote for."
Haru countered. "But politics is hard. Can't understand everything."
"Perfect understanding isn't required," Ren said. "But minimum effort is necessary."
"Minimum?"
"Research. Think. Ask questions."
Simon said deeply, "Socrates taught 'knowledge of ignorance.'"
"Knowing that you're ignorant?"
"Yes. Being aware of not knowing is the beginning of knowledge."
Haru was confused. "Then ignorance isn't bad?"
"Ignorance itself isn't evil," Ren distinguished. "But leaving ignorance alone is problematic."
"You mean there's a duty to learn?"
"More than duty, responsibility," Simon said. "If your actions affect others."
Noa supplemented. "Harm from ignorance can produce the same results as harm from malice."
"So 'I didn't know' isn't an excuse?"
"Depends on situation," Ren said carefully. "If you had no means to know, responsibility is lighter."
"But modern times are information society," Simon pointed out. "Means to know are abundant."
Haru thought. "What about fake news? If you believe wrong information?"
"That's also a form of ignorance," Ren answered. "Lack of information literacy."
"Critical thinking is needed," Simon supplemented. "Don't swallow whole, verify."
"But verifying everything is hard," Haru complained.
"That's why the ability to identify reliable sources matters."
Noa said quietly, "Ignorance is sometimes comfortable."
"Comfortable?"
"Sometimes not knowing is easier. Knowing creates responsibility."
Haru understood. "So some people choose not to know."
"Willful ignorance," Ren named it. "That's ethically problematic."
Simon gave an example. "Environmental issues. Knowing requires changing lifestyle. So don't want to know."
"But that's irresponsible," Haru said.
"Yes. Pushes burden onto next generation."
Ren said severely, "Ignorance in the powerful is especially sinful."
"Why?"
"Because their influence is large. Ignorant decisions make many people suffer."
Simon cited history. "'Noblesse oblige.' Position comes with responsibility."
Haru sighed. "Knowing is heavy."
"But knowing is also freedom," Noa encouraged.
"Freedom?"
"Ignorance is manipulated. Knowledge is the foundation of autonomy."
Ren supplemented. "'Knowledge is power.' Knowledge increases options."
Haru nodded. "Ignorance isn't sin, but remaining ignorant is."
"Good summary," Simon acknowledged.
"But knowing never ends," Haru expressed anxiety.
"That's human destiny," Ren smiled. "Always keep learning."
Simon quoted ancient Greece. "'Know thyself.' The most difficult and most important knowledge."
Haru resolved. "Don't fear not knowing, keep learning."
The three nodded to each other. Ignorance is a starting point. Learning from there is what makes us human.
