Thank you so much Hom Nath Chalise sir. Actually I have read this article and it does not help much. I want some articles where scholars have used genealogy as research method so that I can also develop one for my research.
If it helps, linguistics (my doctorate) has long used a genealogical method in historical-comparative work, mostly pre-Foucault, however. You might look at this link to see if it seems to promise anything: http://linguistics.oxfordre.com/view/10.1093/acrefore/9780199384655.001.0001/acrefore-9780199384655-e-78#. Language family trees go back to at least the 19th c. and are said by some to be derived from existing genealogical work. Others used the term 'genetic' method. Works to check include Bloomfield, 1933, Language; newer tomes on Historical Linguistics; etc. Also, see works by Bakhtin? I am not up on everything in discourse analysis, but older works include
I hope that it makes sense. As genealogy has genesis in historical linguistics, I believe that the article will help me a lot in order to develop methodology. I wonder, how can I have access to this.
