Question

Hello to our great Rabbi, may he live long and well. 
Do you think there is only one clear truth? 
If so, then is only one stream within Judaism correct and all the others wrong, or perhaps none of them has arrived at the absolute truth, and each is right about some things and mistaken about others? More pointedly: when can I respect other streams in a pluralistic way, and when should I give them only a tolerant place, like my attitude toward other religions? And perhaps there is also a bit of truth in other religions, so maybe they too should be granted a pluralistic attitude???
And if we are speaking about matters of worldview, can there be pluralism in Jewish law, as I seem to recall the Rabbi does not think so?!
P.S. If I have found favor in your eyes, I would be happy if the Rabbi would give me a link to his column on the differences between tolerance and pluralism.
