Thanks for mentioning these sources Greg.
The Shape of Ancient Thought: Comparative Studies in Greek and Indian Philosophies by Thomas McEvilley.
Have you read this one Greg? I haven't, but one criticism I've heard is that McEvilley overstates his case in a number of places, drawing unsupported conclusions, etc. But there's probably much of interest in it as well (it's a lengthy text that covers a lot of ground).
"Pyrrhonism and the Mādhyamika" by Adrian Kuzminski, Philosophy East & West Volume 57, Number 4 October 2007
Here's a PDF copy: Pyrrhonism and the Mādhyamika
by Adrian Kuzminski.
No, I haven't really devoted the proper attention to any of these sources honestly - I don't think I've done more than skim any of them. I just bought the McEvilley yesterday after seeing that, bizarrely, the Kindle edition only costs $3.03 vs $31 for the paperback. But I have seen that criticism too and would definitely read it with that in mind.
In general, I'm not up to speed on Western philosophy and I am more and more feeling a sense of lack in that regard. Slowly trying to remedy. If only there were more hours in the day.
For the record the Burton I did not find persuasive at all.
