III. Thinking in the Service of Understanding the World

Whatever principle we wish to advance, we must prove that somewhere we have observed it, or express it in the form of a clear thought which can be re-thought by others. Every philosopher who begins to speak about his fundamental principles must make use of the conceptual form, and thereby makes use of thinking. He therefore indirectly admits that for his activity he presupposes thinking. Whether thinking or something else is the main element in the evolution of the world, we shall not decide as yet. But that without thinking the philosopher can gain no knowledge of the evolution of the world, is immediately clear. Thinking may play a minor part in the coming into being of world phenomena, but thinking certainly plays a major part in the coming into being of a view about them.
