"立法、行政和司法所有权力的集中，无论是集中在一人、少数人或多数人手中，无论是世袭、自任或选举产生，都可以公正地被称为暴政的真正定义。"

Simplified Meaning:

When all government power is controlled by one person or a small group, it's very dangerous and can lead to tyranny. Tyranny is when those in charge use their power unfairly and people lose their freedom. Imagine if in a school, one student gets to make all the rules (legislative), decide who gets punished or rewarded (executive), and judge if the rules are broken (judiciary). If this student favors their friends and acts selfishly, other students would feel powerless and mistreated. This situation mirrors how unfairness and power abuse can grow when a single person or group runs everything, and no one is there to keep them in check. To prevent this, it's better to divide power among different groups so they can balance each other out. This is like having a school principal, teachers, and student council sharing responsibilities to ensure fairness. In our own lives, we should support systems where power is spread out and those in charge are held accountable, ensuring no one abuses their position.
