"所有人生而平等且独立，并享有某些固有权利，当他们进入社会状态时，任何契约都不能剥夺或处分其后代。"

Simplified Meaning:

This quote is about the idea that everyone is born with the same freedoms and rights, and no agreement or deal should take these away from future generations. Imagine you're playing a game where everyone starts with the same chances to win. If you try to make rules that take away this fairness for those who play after you, it’s not right. People are naturally free, and these rights, like freedom and independence, should be protected no matter what. For example, in history, when countries were formed and made governments, they created laws to protect people's rights. These laws are supposed to ensure that future generations, like your children and their children, will also have these freedoms. Just because we agree on some rules today doesn’t mean we can agree to something that will take away these basic rights for our descendants. In everyday life, it’s like making sure a school rule is fair for all students now and also the ones who will come later. It’s important because it builds a fair and just world where everyone has the same basic rights, no matter when they are born. So, whenever you make decisions or set rules, think about how they will affect not just you, but also future generations. Protecting these basic rights ensures everyone gets a fair start in life, always.
