The traditional criteria for distinguishing philosophy from other disciplines have either proved too limited or too broad. Only in its method does philosophy differentiate itself from other disciplines. Philosophy’s point of departure is constituted by spontaneous convictions (intuitions), which, in a first step, need to be articulated through conceptual analysis and then, in a second step, need to be justified; the third step comprises critiquing other philosophers’ thoughts and defending against others’ critique. This article proposes several metaphilosophical theses: Intuitions are not a fundamental source of evidence for philosophical theses, but are instead themselves in need of justification. Consistency is more important than truth; the task of philosophy is to develop extensive and, at the same time, consistent theories about the conceptual background of experience.
