Hunt's extended essay traces the history of the concept of `human rights', or the rights of man, first articulated in these terms in the American Declaration of Independence (1776). It is not, therefore, a history of democracy, or liberalism, or republicanism or a history of political thought. What Hunt is concerned with here is the explicit articulation of the rights of man (life, liberty, equality) as the basis of government, rights which are declared in the eighteenth century, for the first time, to be `natural and inalienable'.
As she herself points out, `rights' and the associated category of citizenship are always, despite the optimism they encapsulate, socially-constructed: so both the American Declaration and that of the French Revolution excluded children, the `insane' (however loosely defined), `foreigners' (ditto), the imprisoned, non-property owners, slaves, religious minorities and - of course - women. Rights, then, are the province of hegemonic ideologies.
Where I slightly part company with Hunt is when she proposes that this idea of `rights' emerges at this time in history because of the rise of the novel (itself a questionable assertion) and the associated feelings of empathy and autonomy that it enables.
The latter part of the book links the emergence of the concept of rights, and the idea of universal equality with darker responses: the development of pseudo-scientific race theories, and the idea of `natural' difference based on ethnicity and/or gender, offering so-called biological bases for the exclusion and oppression of women and whole racial groups, giving rise to Nazism amongst other sinister ideologies.
So whether you're interested in the specific topic of human rights, or the more general issue of how the category of the human is articulated, debated, and contested at different points in history, this is a thoughtful and stimulating read.
