This quote suggests that truly noble and elevated individuals do not place importance on the pursuit of happiness, particularly not on the happiness of others. The reasoning behind this could be that these high-minded individuals are more focused on broader, more abstract concepts such as truth, justice, or the betterment of society. They may consider the pursuit of happiness as a rather trivial or self-centered endeavor, especially when it is at the expense of others.

The indifference to other people’s happiness does not necessarily mean they wish for others’ unhappiness. Instead, it could imply that they do not consider it their responsibility or within their power to make others happy. They might believe that each individual is responsible for their own happiness and that it is not something that can or should be given or taken by another.

Applying this concept to today’s world, we might say that high-minded leaders, for instance, should not focus on short-term happiness or satisfaction, either personal or for their followers. Instead, they should aim for long-term benefits, even if they require sacrifices in the present. In terms of personal development, one might interpret this quote as a call to rise above the pursuit of personal gratification and instead focus on more profound and lasting values.

However, it’s worth noting that this perspective might overlook the importance of empathy and shared joy in human relationships and societies. While it’s true that we should not depend on others for our happiness, being indifferent to others’ emotions might lead to a lack of connection and understanding. As with many philosophical concepts, balance is key.
