The problem, of course, was that people did not seem to understand the difference between right and wrong. They needed to be reminded about this, because if you left it to them to work out for themselves, they would never bother. They would just find out what was best for them, and then they would call that the right thing. That's how most people thought.
The essence of the quote highlights a fundamental issue in human behavior regarding moral judgment. It suggests that many individuals lack a clear understanding of right and wrong, often resorting to self-serving decisions rather than ethical considerations. When left to their own devices, they tend to prioritize personal gain over moral integrity, which can lead to ethical ambiguity.
This observation reflects a broader social concern, where the distinction between self-interest and true morality becomes blurred. The author implies that there is a need for guidance and reminders about ethical principles, emphasizing the importance of education and reflection in fostering a better understanding of right versus wrong among people.
