<P> The 17th - century cleric and philosopher Richard Cumberland wrote that promoting the well - being of our fellow humans is essential to the "pursuit of our own happiness". Locke never associated natural rights with happiness, but his philosophical opponent Gottfried Wilhelm Leibniz made such an association in the introduction to his Codex Iuris Gentium . William Wollaston's The Religion of Nature Delineated describes the "truest definition" of "natural religion" as being "The pursuit of happiness by the practice of reason and truth". An English translation of Jean - Jacques Burlamaqui's Principles of Natural and Politic Law prepared in 1763 extolled the "noble pursuit" of "true and solid happiness" in the opening chapter discussing natural rights . Historian Jack Rakove posits Burlamaqui as the inspiration for Jefferson's phrase . </P> <P> Another possible source for the phrase is in the Commentaries on the Laws of England published by Sir William Blackstone, from 1765 to 1769, which are often cited in the laws of the United States . Blackstone argues that God' has so intimately connected, so inseparably interwoven the laws of eternal justice with the happiness of each individual, that the latter cannot be attained but by observing the former; and, if the former be punctually obeyed, it cannot but induce the latter . In consequence of which mutual connection of justice and human felicity, he has not perplexed the law of nature with a multitude of abstracted rules and precepts, referring merely to the fitness or unfitness of things, as some have vainly surmised; but has graciously reduced the rule of obedience to this one paternal precept, "that man should pursue his own true and substantial happiness ." This is the foundation of what we call ethics, or natural law .' </P> <P> Other tripartite mottos include "liberté, égalité, fraternité" (liberty, equality, fraternity) in France; "Einigkeit und Recht und Freiheit" (unity, justice and liberty) in Germany and "peace, order, and good government" in Canada . It is also similar to a line in the Canadian Charter of Rights: "life, liberty, security of the person" (this line was also in the older Canadian Bill of rights, which added "enjoyment of property" to the list). </P> <P> The phrase can also be found in Chapter III, Article 13 of the 1947 Constitution of Japan, and in President Ho Chi Minh's 1945 declaration of independence of the Democratic Republic of Vietnam . An alternative phrase "life, liberty, and property", is found in the Declaration of Colonial Rights, a resolution of the First Continental Congress . The Fifth Amendment and Fourteenth Amendment to the United States Constitution declare that governments cannot deprive any person of "life, liberty, or property" without due process of law . Also, Article 3 of the Universal Declaration of Human Rights reads, "Everyone has the right to life, liberty, and security of person". </P>
