What luck for rulers that men do not think?

The phrase suggests that rulers benefit from the apathy or lack of critical thinking among the populace, as it allows them to maintain control and power without challenge. When people do not question authority or think deeply about their circumstances, they are more easily manipulated and governed. This dynamic underscores the importance of education and awareness in fostering a more informed citizenry that can hold leaders accountable. Ultimately, the statement serves as a cautionary reminder of the dangers of complacency in society.
