This quote suggests that class differences, or the division of individuals into social and economic groups, is fundamentally unjust. It implies that these divisions are not based on merit, ability, or even natural differences, but rather on force, which can be understood as the power and influence of those at the top of the social hierarchy.

The phrase “contrary to justice” underscores the belief that class differences are inherently unfair. Justice, in its most basic form, is about fairness and equality. If class differences were based on inherent or earned attributes, they might be seen as just. However, the quote suggests that they are not, but are instead based on the ability of those in power to enforce and maintain these divisions.

“In the last resort, based on force” implies that these divisions persist because of the power structures in place. Those with wealth and influence have the means to maintain their status and keep others in lower classes. This force can take many forms, from economic and political power to control over resources and opportunities.

In today’s world, this idea is highly relevant. Income inequality and class divisions are persistent issues in many societies. The rich continue to get richer, often at the expense of the poor. This can be seen in the control over resources, the influence on political decisions, and the opportunities available to different classes.

The idea can also be applied to personal development. Recognizing the role of power structures in our lives can help us understand our own positions and the challenges we face. It can inspire us to strive for justice in our own actions and relationships, to challenge unfair systems, and to work towards a more equitable society. It can also make us more empathetic to those who are disadvantaged by these systems, and more motivated to help them.
