Other rights

Custom also plays a role. Implied or unenumerated rights are rights that courts may find to exist even though not expressly guaranteed by written law or custom; one example is the right to privacy in the United States, and the Ninth Amendment explicitly shows that other rights are also protected.

The United States Declaration of Independence states that people have unalienable rights including "Life, Liberty and the pursuit of Happiness". It is considered by some that the sole purpose of government is the protection of life, liberty and property.

Some thinkers have argued that the concepts of self-ownership and cognitive liberty affirm rights to choose the food one eats, the medicine one takes, and the habit one indulges.
