Schiller is closely related to Goethe but not to Kant. Of course he knew Kant who is actually the most wellknown and famous of the German philosophs at that time. In his "Kritik der reinen Vernunft" he initiated and formulated the fundamental ideas of the modern and common point of view in philosophics.
When you take a closer look you could even say that they were some kind opponents in philosophical questions.
