Where can I see a copy of Mohammad Khatani's speech at Harvard?

Answer 1

This will give you a summary. If you are an alumnus or a paying member you might be able to get it for being a member. If not, I am sure Harvard will be glad to sell it to or the public. I would check with Harvard later in the week.

Answer 2

I think you mean Khatami. The link from Harvard's site to info on his speech does not work. Must have been too controversial.
