Abstract: | This article discusses John Stuart Mill's voluntary slavery argument in On Liberty. The author shows that standard interpretations of the argument rely on the assumption that part of Mill's objection to voluntary slavery is the permanent nature of the decision. However, in correspondence, Mill also objects to voluntary ‘coolie’ labour contracts, which he regards as a form of slavery. This produces difficulties for standard interpretations of the voluntary slavery argument. Finally, the author provides a revised interpretation of Mill's argument to solve this problem. |
