Marshall 1992,第641頁:“In general, anarchism is closer to socialism than liberalism. ... Anarchism finds itself largely in the socialist camp, but it also has outriders in liberalism. It cannot be reduced to socialism, and is best seen as a separate and distinctive doctrine.” [一般来说,无政府主义比自由主义更接近社会主义……无政府主义在很大程度上属于社会主义阵营,不过它也比起自由主义走得更前,故它不能够以社会主义之名涵盖之。因此最好视它作一门独立兼具自身特色的学说。]
