Q: When you do get back to the Indus script, what are you hoping to do?
A: I have some unpublished, rather unfinished papers. One of the things I want to get back to is whether I can fix the phonetic values of some signs. I have some leads, particularly concerning the phonetic values of the terminal signs, which are very important. If at least a few phonetic values could be established, they will have a cascading effect. Many of the symbols could yield their results. But this is still a dream.
I also still want to work on the filter theory, whether by combining Dravidian theory, Indo-Aryan or by looking at the finds in the Indus Valley itself.
But I have no illusions that I will decipher the Indus script, nor do I have any regret. I think the ultimate decipherment of any language is built on the unsuccessful attempts of so many earlier scholars, so I am content to remain one of them. I am very hopeful that further discoveries by teams like Kenoyer's and others, and the active work of Parpola and his team will all bear fruit, hopefully in my lifetime.
