Abstract

This contribution analyses the scientific and political meaning of the concept of ‘population’ within Thomas Robert Malthus’ thought. It is here argued that by encapsulating ‘population’ in a scientific principle, the author not only aimed at contrasting radical and revolutionary theories of his time; he was also looking for a renovation of the role principles hold in scientific reasoning. He considered this crucial for delineating a plausible science for such an elusive political object as society. Through an examination of key passages of Malthus’ theoretical production – his critique of previous definitions of ‘population’, his reassessment of the natural history of society, and the use of selected metaphors to explain his political thought – it is possible to observe how the author attempted to naturalize society and the inequalities arising from its historical laws. As shown in the conclusions, Malthus’ scientific and political effort was directed towards questioning possibilities to reduce the history of social relations to a path of rational progress, which is consistent with the way he re-conceptualized ‘population’ as regarding the fate of the people and their chances to transform the future in the plausible outcome of their political action in the present.
