Philosophical means to do with deep questions, or calm about misfortune. A philosophical question, philosophical about the loss, take a philosophical view.
The second sense is much the commoner in speech, where being philosophical about something means accepting it without complaint. It comes from the Stoics, who taught exactly that, so the everyday use is closer to the discipline than it looks.
