In recent decades the socialists have attracted more attention and historical study than other social reformers. The extreme positions, utopian socialism and Marxism, have been the subject of many studies, and indeed, have been investigated to the neglect of the intermediate and moderate forms of socalism. The concentration of study upon the extreme positions may perhaps be explained in that they are older movements and they have had an influence that certainly makes for quantitative importance. Moreover, those who take extreme positions are often the first to gain attention.
