The neo-Kantian reception of Schiller between Platonism and Kantianism

In the second half of the 19th century, several neo-Kantians became interested in Schiller's philosophy, thus playing a fundamental role in his appreciation as a philosopher. 

Schiller's philosophy is characterized by a peculiar mixture of Kantian and (neo)Platonic elements. 

There are two paradigmatic readings of Schiller's philosophy: the Kantian one emphasizes Schiller's adoption of the critical framework of Kant's transcendental philosophy and highlights the separation between the sensual and ideal worlds; the Platonic one emphasizes the role of beauty as the harmonious union of the two worlds, thus revealing Schiller's ethical-metaphysical commitments.

The question behind the project is: If neo-Kantian philosophers were attracted to Schiller's Kantianism, how did they respond to his Platonism?
