Hi,&nbsp;Bahram:<br /><br />I have uploaded your edited document and hope that you find the suggestions helpful. If you have any questions, please send a message to me via Editor World.<br /><br />Your paper is excellent and reminded me of my old graduate days. I envy you working at such a level, in a field that is still important and relevant.<br /><br />I went over your paper very carefully, several times, making more edits than I really had to, but you can choose which to accept and which to reject. Here and there, I tried to clarify what is, after all, a very difficult subject but not to change your meaning. Please proofread carefully in case I failed at the&nbsp;latter. I remember defending a passage in Hegel once, only to discover after 20 minutes that a typo in the book had rendered his meaning the reverse of what I was claiming -- and all because of one word.<br /><br />MS Word includes tracked changes by default.

I really enjoyed helping with your paper<br /><br />Best wishes - TypeRighter (aka George)<br /><br />I am usually available for editing between 6:00 am and 10:30 pm.
