John Stuart Mill (1806-1873) was a highly influential English philosopher of the Victorian Era. His writings were influenced by the Enlightenment thinkers and German Romanticism. Besides philosophical works, he wrote on mathematics, language, and logic. Well ahead of his time, he advocated the abolition of slavery and was a proponent of both children's and women's rights. However, he is best remembered for his essays on utilitarianism, a philosophy developed by Jeremy Bentham (1748-1832).
