This paper offers a new interpretation of the unity of the human soul’s parts in De Anima II.3, drawing on the mathematical notion of dimension. Dimensionality, understood as an intrinsic property that parameterises a system’s complexity by the number of its independent yet ordered parameters, provides a suitable framework for explaining the unity of the tripartite human soul. The nutritive, the perceptual, and the intellectual parts emerge as three definitionally distinct yet operationally ordered dimensions of a human being. Though anachronistic, this dimensional account is philosophically fruitful: it effectively unifies three...

Viewing Popper through a republican lens would reveal that there is a robust and coherent theory behind his attack on the “enemies of the open society”. The paper focuses successively on the concept of freedom understood as nondomination, on the role of the state and the rule of law, and on democracy. That Popper might be classified “as a republican,...
