 A related issue concerns the scope of aesthetic ideas. Matherne (2013) challenges interpretations on which aesthetic ideas can present or express only moral or rational concepts, arguing that they can also present empirical concepts and human emotions. Reiter and Geiger (2018) also propose expanding the scope of what can be presented in an aesthetic idea, arguing that, insofar as aesthetic ideas present the rational idea of humanity in our person, they show the “range and variety of human freedom”. Vaccarino Bremner (2021) suggests a different way of broadening the scope of aesthetic ideas, arguing that they do not just present or express concepts, but call for us to revise them.
