The Philosophical Radicals was a philosophically-minded group of English political radicals in the nineteenth century inspired by Jeremy Bentham and James Mill. Individuals within this group included Francis Place, George Grote (1794–1871), Joseph Parkes, John Arthur Roebuck, Charles Buller, John Stuart Mill, Edward John Trelawny, and William Molesworth.[1]

Amongst other things, members of their group were the publishers of Darwin and ran the progressive journal the Westminster Review.
