III. Thinking as the Instrument of Knowledge

What is impossible with regard to Nature, namely, creating before knowing, is accomplished with regard to thinking. Were we to refrain from thinking until we had first gained knowledge of it, we should never attain it. We must resolutely think straight ahead, and then afterwards gain knowledge of the thinking we have done by observing it. When we want to observe thinking, we must ourselves first create the object to be observed: the existence of all other objects is provided for us without any activity on our part.
