This quote is a potent critique of the relationship between those who govern and those who are governed. It suggests that the dynamics of power, authority, and obedience can often lead to a situation where both rulers and the ruled are acting in ways that lack principles, ethics, and integrity.

The phrase "hell more unprincipled" is a metaphorical way of saying a situation or a place that is worse or more corrupt. It implies that Thoreau sees the current state of governance and societal obedience as deeply flawed and corrupt, almost akin to a kind of hell.

In the context of today’s world, this quote is still highly relevant. It can be seen as a call to question and challenge the status quo, to scrutinize our leaders and their actions, and to examine our own complacency or complicity in maintaining systems of power that may be unjust or unethical. It is a reminder that we should not blindly accept authority but should always strive for a society that is guided by principles of justice, fairness, and integrity.

On a personal level, it encourages us to reflect on our own principles and the ways in which we might be compromising them. Are we acting in ways that align with our values, or are we simply following the crowd, even when it leads us down an unprincipled path? It pushes us to strive for personal integrity, to stand up for what we believe is right, and to resist the temptation to simply go along with the majority or obey authority without question.

In essence, this quote is a powerful commentary on the importance of principles in both governance and personal conduct, and a reminder that we should always strive to uphold these principles, even when it is difficult or unpopular to do so.
