Why do we need to study Iqbal on his own terms? I am hoping that Ahmad Safi will post something on that issue soon (he usually answers this question with a more natural flow than I can). At the suggestion of Connie Nash, I am starting to offer my tentative definitions of the proposed key areas of Iqbal Sciences, beginning with literature.
Literature may be redefined as a demonstration of the life of the collective ego with the aid of language. This collective ego is what Sir Syed Ahmad Khan described as "the spirit of all human beings" in his short story 'Time Bygone'. Later, Iqbal stated in his paper 'The Muslim Community' that concepts like Zietgiest, collective consciousness, etc, are nothing more than faint and incomplete hints in guessing at this "collective ego" which is therefore different, and much bigger, than what is implied in any of the concepts of modern philosophy or psychology.
I hope to add more in this post. But basically I wanted to propose this definition for discussion (and it can be transferred to the SOIS Blog later): Literature is a demonstration of the life of the collective ego with the aid of language.
