why 'Indian philosophy' is adhoc?

What does "philosophy" refer to in our common parlance? Production of theoretical knowledge, of course. Whatever theoretical knowledge Indian traditions produced, in a way, is subordinated to the experiential knowledge. Heuristics, generalizations, tricks, etc, are descriptive. Focussing on arguments concerning the former, without telling what they are after (in this case, experiential knowledge) is just unproductive: that is,their hypothesis that Indian traditions are set of philosophies have not explained any thing at all; or explained only the set of the facts they have chosen to explain in the first place (and therefore, adhoc).
