Now, while by today's philosophic standards Schiller's speculations would be considered wildly metaphysical and disconnected from the sciences, compared with the metaphysicians of his day (Hegel, McTaggart, etc.), Schiller saw himself as radically scientific. Schiller gave his philosophy a number of labels during his career. Early on he used the names "Concrete Metaphysics" and "Anthropomorphism", while later in life tending towards "Pragmatism" and particularly "Humanism".
