III. Thinking as the Instrument of Knowledge

The reason why we do not notice the thinking which goes on in our ordinary life is no other than this, that it is caused by our own activity. Whatever I do not myself produce appears in my field of consciousness as an object; I contrast it with myself as something the existence of which is independent of me. It comes to meet me. I must accept it as the presupposition of my thinking. As long as I think about the object, I am absorbed in it, my attention is turned on it. To be thus absorbed in the object is just to contemplate it by thinking. I attend, not to my activity, but to its object. In other words, whilst I am thinking, I pay no heed to my thinking which is of my own making, but only to the object of my thinking which is not of my making.
