III. Thinking as the Instrument of Knowledge

I should like to mention a widely current error which prevails with regard to thinking. It is often said that thinking, in its original nature, is never given. The thinking-processes which connect our perceptions with one another, and weave about them a network of concepts, are not at all the same as those which our analysis afterwards extracts from the objects of perception, in order to make them the object of study. What we have unconsciously woven into things is, so we are told, something widely different from what subsequent analysis recovers out of them.
