This quote suggests that any form of unity that doesn’t arise naturally from the collective agreement or consensus of a group is a form of oppression or tyranny. The "multitudes" here represent the diverse individuals that make up a society or a group. If unity is imposed from the top, without considering the ideas, beliefs, and desires of the individuals, it becomes a form of tyranny. It becomes a force that suppresses individuality and diversity, rather than a bond that brings people together.

In the context of today’s world, this quote could be applied to various situations. For instance, in politics, it could refer to the importance of democracy, where the power and the decisions come from the people, the multitudes, rather than being imposed by a dictator or a small group of elites. Any unity or consensus that doesn’t come from the democratic process could be seen as tyranny.

In the business world, this quote could be applied to the importance of diversity and inclusion in the workplace. Any unity that doesn’t take into account the diverse perspectives, experiences, and ideas of all employees could be seen as a form of tyranny. It could lead to a culture that suppresses diversity and promotes conformity, which could stifle innovation and productivity.

In terms of personal development, this quote could be interpreted as the importance of self-awareness and authenticity. Any unity or coherence in our personality that doesn’t come from our own diverse experiences, values, and beliefs could be seen as a form of self-tyranny. It could lead to a life that is not true to ourselves, but is instead shaped by external pressures or expectations.
