among these are Life, Liberty and the pursuit of Happiness
The Declaration specifically mentions three rights which human beings possess by birth or by nature-life, liberty and the pursuit of happiness. No one may rightfully deny us these things. Nor, since they are "unalienable," may we rightfully surrender them.
It is worth remarking that the Declaration does not proclaim a right to happiness itself. Happiness is not something we have by nature. Rather we are born with minds and talents that we may use to pursue happiness.
The Declaration says that these three rights are "among" our natural rights. We have others in addition. Among the most important of these are the rights of conscience and property. These are among the rights specifically guaranteed in the Constitution's first ten amendments, known as the Bill of Rights.
The right of conscience means religious freedom. As explained in the Virginia Declaration of Rights of 1776: "religion, or the duty which we owe to our Creator, and the manner of discharging it, can be directed only by reason and conviction, not by force or violence; and therefore all men are entitled to the free exercise of religion, according to the dictates of conscience." Each of us has a right to worship God in his own way and time.
As for property rights, they were at the heart of the dispute which led to the American Revolution. When Americans at the time listed the rights of man, they often said "life, liberty, and property." Boston's 1772 "Rights of the Colonists" were typical: "Among the natural rights of the colonists are these: First, a right to life; secondly to liberty; thirdly to property." As with happiness, this is not a right to property itself, but a right to use one's talents to acquire property, and to use it as one sees fit, as long as one does not injure oneself or others.
