J.S. Mill definitely requires a bust..an old-time bust straight from the 19th century...one that even LOOKS like him. Very important guy...son of a very important guy, also an activist...god-father of Bertrand Russell I hear tell too, but most important for creating the logical approach on which modern experimental science bases itself. For that he is rarely acknowledged, but Ernst Cassirer hated him for it, and Mill hated his owled friend August Comte for trying to turn science into religion. J.S. may be remembered for being an outspoken womens rights activist in a day far before these things were openly spoken of. But last of all, he is in my economists section, for that is what he most surely defined as opposed to Marx and Engels during the same or similar time-frame.
