State of Nature is a term in political philosophy used in social contract theories to describe the hypothetical condition that preceded governments. There must have been a time before government, and so the question is how legitimate government could emerge from such a starting position, and what are the hypothetical reasons for entering a state of society by establishing a government.

In some versions of social contract theory, there are no rights in the state of nature, only freedoms, and it is the contract that creates rights and obligations. In other versions the opposite occurs: the contract imposes restrictions upon individuals that curtail their natural rights.

The term "state of nature" appears in the writings of Thomas Aquinas (born c. 1225) (see De Veritate, Question 19, Article 1, Answer 13). Aside from its influence upon later Political Philosophy, the use of the term in Aquinas is also of key importance for the development of the Catholic "Natural Law" Theological Tradition; its biblical theological provenance goes back to a pregnant statement of the Apostle Paul in his Letter to the Romans (Romans 2:12-16).

Sir David Frederick Attenborough ( /ˈætənbərə/) OM, CH, CVO, CBE, FRS, FZS, FSA (born 8 May 1926) is a British broadcaster and naturalist.

His career as the face and voice of natural history programmes has endured for more than 50 years. He is best known for writing and presenting the nine Life series, in conjunction with the BBC Natural History Unit, which collectively form a comprehensive survey of all life on the planet. He is also a former senior manager at the BBC, having served as controller of BBC Two and director of programming for BBC Television in the 1960s and 1970s.

Attenborough is widely considered a national treasure in Britain, although he himself does not care for the term. He is a younger brother of director, producer and actor Richard Attenborough.

Attenborough was born in Isleworth, west London, but grew up in College House on the campus of the University College, Leicester, where his father, Frederick, was principal. He is the middle of three sons (his elder brother, Richard, became an actor and his younger brother, John, an executive at Italian car manufacturer Alfa Romeo). During World War II his parents also adopted two Jewish refugee girls from Europe.
