It's not an 'I think' which accompanies all experience but a certain distinct and constant feeling or taste without any associated I, but which in a question filled world demands an 'I' to answer for it. The 'I' never fully appears but the demand for it is always there, which becomes a demand for recognition, for acknowledgement which stands in for the absent 'I' in day to day commerce. The questioning branches out into endless tributaries but mostly fails to deliver the only true question which can only arise from the bare and silent situation of mere being.
