"En una república debe observarse esta regla, que la mayoría no debe tener el poder predominante."

Simplified Meaning:

In a system where people vote to make decisions, it's important that the largest group of people doesn’t have all the control. Imagine you're in a class of 30 children deciding which game to play at recess. If 16 of them always get to choose, the others might never get to play their favorite games. To avoid this, the teacher might suggest rotating who picks the game or mixing ideas to keep things fair for everyone. For example, in a country's government, if the same large political party always has the full power to decide laws, other viewpoints might be ignored. This could lead to decisions that don't consider everyone's needs, just those of the majority. By making sure even smaller groups have a say, the decisions can be better and more balanced for everyone. This approach ensures that all voices contribute to the decision-making process, which helps maintain fairness and equality.
