John Stuart Mill

John Stuart Mill (20 May 1806 – 8 May 1873), English philosopher, political theorist, political economist, civil servant and Member of Parliament, was an influential British Classical liberal thinker of the 19th century whose works on liberty justified freedom of the individual in opposition to unlimited state control.[2] He was a proponent of utilitarianism, an ethical theory developed by Jeremy Bentham, although his conception of it was very different from Bentham's. Hoping to remedy the problems found in an inductive approach to science, such as confirmation bias, he clearly set forth the premises of falsification as the key component in the scientific method.
