Our nations unalienable right are 'Life', 'Liberty', and 'The pursuit of happiness'. An unalienable right is our rights that cannot be changed, transferred, or sold.
Government by consent. The Declaration says, "Governments are instituted by men, deriving their just powers from the consent of the Governed." This means that government gets all its power from the people. The people set up the government. The people run the government, the government does not run the people.
Why does a just government need Government by consent you might ask? The term implies that the people of a country or territory are sovereign and consent, in a direct referendum or through elected representatives, to the establishment of their own government.
Who is responsible for protecting or guaranteeing our unalienable rights? The citizens. We protect these rights because they are our given rights. If the government breaks these rights for us, its our job to do something about it.
Are the principles of unalienable rights and government by consent in the Declaration outdated, or are they still true today? They are still true today, they're more true today then they were back then. Back then women weren't aloud to own property and they had slaves. But today we don't have any slaves and women can own their own property. So yes, these rights are still true today.
These principles do matter to me because without our natural right what would we have? What would do? These are our rights and we deserve to keep them, and if any destroys our rights, they can be punished.
