John Stuart Mil:
(Pentonville, 20 May 1806 – Avignon, 8 May 1873).
English philosopher and economist. He was a proponent of utilitarianism, the ethical theory proposed by his godfather Jeremy Bentham. He described his own version of this in the work Utilitarianism, indicating the need to distinguish between different kinds of pleasure. In his well-known work On Liberty, he set out the harm principle.
Somerville College Library, the library of Somerville College (Oxford) contains his collection of around 1700 books (the so-called John Stuart Mill Library).
The liberty of the individual must be thus far limited; he must not make himself a nuisance to other people.
The only freedom worthy of the name is the freedom to pursue our own good, in our own way, as long as we do not try to rob others of theirs or thwart them in their efforts to achieve it.
